Travis County
State of Texas
Travis County is the 8th largest jurisdiction in Texas — 1,290,188 residents. This page is the permit route for that jurisdiction: the fifteen steps from working out who has a say over an address through to permission to operate, the documents this authority publishes, and 62 answers taken from those documents and dated.
Permitting 5 steps · 28 questions

Confirm who has a say over your address
A city address is usually permitted by the city, not the county — but not always, and some authorities keep building and hand electrical to someone else. Getting this wrong costs the whole submittal, because every requirement below belongs to whoever actually holds jurisdiction. Check the overlays in the same pass: an HOA, a historic district, a windstorm certification or a system-size cap can reshape the design, and all of them are cheaper to find now than after the array is laid out.
- Is this authority the AHJ for residential solar at this address? Partially. Travis County IS the AHJ for the development/floodplain permit for residential rooftop PV in the unincorporated county. It is NOT the building-code or electrical AHJ and does not inspect the PV system. 90% · authority permit page
- What does this authority permit itself, and what does it delegate? Delegated — the county permits land development only (floodplain, erosion/sedimentation control, site plan). Building-code inspection is delegated to third-party licensed inspectors under Code 480.006; electrical is held by the serving utility (Austin Energy in its territory), not by the county. 90% · adopting ordinance (county-hosted PDF)
- Is a permit required for a residential rooftop PV system? Yes. A Development (Residential) permit is required before installing rooftop solar in unincorporated Travis County. 95% · authority permit page + ordinance 464.061
- Is there a separate electrical permit, or is it combined? Neither — Travis County issues no electrical permit at all. The electrical permit is issued by the utility path: in Austin Energy territory, an Austin Energy 'Auxiliary Power Electrical Permit' via Austin Build + Connect. The county development permit and the utility electrical permit are entirely separate instruments from separate bodies. 85% · utility permitting manual
- Is a HOA or architectural approval required first? No. Travis County does not require HOA or architectural approval as a precondition of the development permit; it is not a step in the county's published process and no such requirement appears in the code. 65% · authority permit page + code search
- Is there a historic-district review? No historic-district review. Travis County has no zoning or historic-district authority over private property in the unincorporated area. 70% · ordinance / code search
- Is a wind or windstorm certification required? No wind or windstorm certification required by Travis County. 60% · code search (absence)
- Is a Specific Use Permit or Council approval ever required? No Specific Use Permit or Commissioners Court approval is required for residential rooftop PV. Travis County has no zoning power. The only Commissioners Court route in this area is a floodplain variance under Code Ch. 464 Subchapter C Division 4, which a rooftop array would not normally engage. 70% · ordinance
- Is there a system-size cap on residential generation? No county cap on residential generation size. At utility level in Austin Energy territory, a system is not capped but crossing 25 kW-ac (solar + ESS combined) triggers an additional Distributed Generation Planning Application and/or Transformer Capacity review before the permit can activate. 80% · utility permitting manual

Check who is allowed to apply
Several authorities require the electrical permit to be pulled by a licensed electrician, or require the contractor to be registered with them BEFORE applying. Registration is not same-day. This is second on the list rather than fourth because it is the step most likely to stop the job before the drawings matter.
- Who is allowed to pull the electrical permit? Licensed electrician — in Austin Energy territory. 'All solar PV systems require an Auxiliary Power electrical permit to be pulled by a licensed electrician. Homeowner exemptions are NOT allowed for solar projects.' Travis County itself imposes no such rule because it issues no electrical permit; its development permit is applied for by the owner/applicant. 85% · utility interconnection guide
- Must the contractor be registered with this authority before applying? No — Travis County does not require contractor registration for the development permit. (In Austin Energy territory, Vendor Registration with the City of Austin IS required before an Auxiliary Power EP application can be submitted.) 70% · authority permit page + utility permitting manual
- Is a homeowner permitted to self-install and self-permit? For the county development permit — yes, the property owner applies. For the electrical work in Austin Energy territory — no: 'Homeowner exemptions are NOT allowed for solar projects.' 80% · utility interconnection guide + authority permit page

Build the submittal package
Almost everywhere wants a site plan, a one-line or three-line electrical diagram, equipment cut sheets with listings, and a structural attachment detail. Build it against the published checklist rather than the last jurisdiction you worked in — the checklist is what the reviewer marks against.
- What documents make up a complete submittal? County: (a) address; (b) TCAD legal description — Property ID (PID), lot, block, phase and section; (c) proposed construction start date; (d) estimated cost of construction; (e) a site plan showing all proposed improvements, location of waterways, an ESC (erosion & sedimentation control) Plan, a Restoration Plan, location of all easements and setbacks, location of floodplain, and location of on-site sewage facilities where applicable. The separate PDF Residential Checklist is no longer uploaded — its questions are now built into the online application. Utility (Austin Energy): DGPA form, wire diagram / design packet, and a signed Interconnection Agreement (now mandatory for all residential DG). 95% · published checklist / permit page
- How many copies, and in what format? Electronic upload through the MyGovernmentOnline (MGOConnect) portal; no paper copies described in the current process. Note that Code 464.062 still says an applicant shall submit the application 'along with plans in triplicate, drawn to scale' — paper-era text the online process appears to have superseded. 70% · ordinance + portal process page
- Is a site plan required, and what must it show? Yes. The site plan must show: all proposed improvements; location of waterways; ESC Plan; Restoration Plan; location of all easements and setbacks (if applicable); location of floodplain (if applicable); location of on-site sewage facilities (if applicable). 95% · published checklist
- Is a one-line / three-line diagram required? No at county level — Travis County requires no one-line or three-line diagram (the term 'one-line' returns zero hits in the county code and the solar page's document list has no electrical drawing). Yes at utility level — Austin Energy requires a 'Wire diagram/design packet for the proposed system design' as a mandatory upload on every Auxiliary Power EP. 90% · utility permitting manual + code search
- Are string and conductor calculations required? Not required by the county. Austin Energy's inspection checklist requires that 'Module string configuration is designed per inverter manufacturer's string sizing calculations' and that overcurrent devices be sized per NEC 705.11/705.12 — checked at inspection rather than demanded as a submittal calculation. 75% · utility inspection checklist (DIG Appendix C)
- Is a structural PE stamp required, and at what threshold? No structural PE stamp for a standard roof-parallel residential array. Travis County imposes none (Ch. 480 does not reach a rooftop array). In Austin Energy territory a PE seal IS required where modules are not mounted parallel to the roof surface, extend past the existing roof, are on a new separate structure (ground mount), are solar roof tiles, or the installation is commercial — and separately, all Energy Storage System plans must be sealed by a Texas-licensed PE. 85% · utility interconnection guide
- Is an electrical PE stamp required, and at what threshold? No electrical PE stamp for standard residential rooftop PV. AE's inspection checklist requires PE-sealed electrical plans only for commercial installations, modules on new structures, modules extending past the roof, modules not parallel to the roof, and solar roof tiles. 80% · utility inspection checklist

Apply and pay
Most authorities now take the whole application through a portal, and several states cap or constrain what a residential solar permit may cost. Check whether plan check is billed separately before you quote the job.
- Which permit portal does this authority use? MyGovernmentOnline / MGOConnect (mgoconnect.org) for the Travis County development permit. Austin Build + Connect (AB+C) for the Austin Energy Auxiliary Power electrical permit and its inspections. Travis County also runs 'Camino' (app.oncamino.com/traviscounty) as a supplemental pre-application requirements tool, which the county states is NOT a substitute for the Code. 95% · portal landing page
- Can the whole application be completed online? Yes. Account creation, application, document upload, status tracking, comment response and permit issue (by email) are all described as online. The county notes 'All communication associated with your permit application will be conducted within the same website.' 90% · authority permit page
- What does a residential solar permit cost? $149 per application for an 'A' Residential floodplain/development permit; $287 per application if a 'B' Residential permit applies (property in the special flood hazard area). Acreage does not change either figure. Additional residential review fees may attach: Permanent Water Quality Control $203/lot, Site Complexity – Environmental $187/application. 55% · published fee schedule
- How is the fee calculated? Flat — 'per application', explicitly not varying with acreage for residential ('A' Residential <1 acre and >1 acre are both $149). Non-residential, by contrast, is valuation-based ($137 + $1.99 per $1,000 of construction valuation). 80% · published fee schedule
- Is there a separate plan-check fee? No separate plan-check fee is listed for a residential development permit. There is an 'Additional Reviews Fee' (10% of the original fee where there is no change and under 6 months of non-activity, 100% after six months), a $245 Construction Plan Revisions fee, and optional Expedited Review (varies, plus 31.32% expedited review overhead). 70% · published fee schedule

Plan review — and start the utility in parallel
Interconnection is a separate process from the permit and usually the longer pole. Where the utility does not depend on the permit being issued, running both at once is the single biggest saving available on a residential job.
- How long is an issued permit valid before it expires? If development has commenced: on completion of the project, or 5 years from issue, whichever comes first. If development has NOT commenced: 180 days after the permit was issued. 95% · ordinance
- Which utility handles interconnection here? Split by address — there is no single utility for unincorporated Travis County. Austin Energy serves a large share: its territory is ~437 square miles, 'most of that area falls within Travis County', only 'about half of our service area is within the Austin city limits', and it names Travis County and Del Valle (unincorporated) among the areas served. The remainder of the unincorporated county is served by electric cooperatives (Pedernales EC to the west/north, Bluebonnet EC to the east) — which I could NOT confirm from their own sources in this run. 65% · utility service-area page
- Where does the utility sit in the sequence? Before permit (utility gates the permit). In Austin Energy territory a signed Interconnection Agreement is now required for ALL residential DG projects and must be reviewed and approved by AE staff before the Auxiliary Power EP can be activated. AE also runs a DG Planning Application / Transformer Capacity review where DG output (solar + ESS) is ≥25 kW-ac, and a DG Plan Review whenever an ESS is included. The county development permit has no utility dependency. 85% · utility permitting manual
28 questions answered against Travis County’s own published documents
Q1 Is this authority the AHJ for residential solar at this address? Core Jurisdiction & scope
Partially. Travis County IS the AHJ for the development/floodplain permit for residential rooftop PV in the unincorporated county. It is NOT the building-code or electrical AHJ and does not inspect the PV system.
Why the confidence is not higherCounty's own Solar Permit page requires a Development (Residential) permit; Code Ch. 480 and Ch. 201 both exclude rooftop PV on a single-family dwelling from any building/fire building-permit requirement. See jurisdiction.why for the controls run.
authority permit page checked 2026-08-28 https://www.traviscountytx.gov/tnr/development-services/apply-for-a-permit/residential-solar-permit
Q2 What does this authority permit itself, and what does it delegate? Core Jurisdiction & scope
Delegated — the county permits land development only (floodplain, erosion/sedimentation control, site plan). Building-code inspection is delegated to third-party licensed inspectors under Code 480.006; electrical is held by the serving utility (Austin Energy in its territory), not by the county.
Why the confidence is not higherCode 480.006 names the six categories of third-party inspector the builder must contract; the county's own residential permit pages repeat 'must be performed by a licensed 3rd party inspector'. No county electrical permit type exists in the fee schedule or on any permit page.

Q3 Is a permit required for a residential rooftop PV system? Core Jurisdiction & scope
Yes. A Development (Residential) permit is required before installing rooftop solar in unincorporated Travis County.
Why the confidence is not higherThe county's Solar Permit page gives an 8-step process ending 'Receive the Permit … post the permit somewhere visible from the public right of way'. Code 464.061 independently requires a development permit before any construction, including additions to existing buildings and structures.

Q4 Is there a separate electrical permit, or is it combined? Core Jurisdiction & scope
Neither — Travis County issues no electrical permit at all. The electrical permit is issued by the utility path: in Austin Energy territory, an Austin Energy 'Auxiliary Power Electrical Permit' via Austin Build + Connect. The county development permit and the utility electrical permit are entirely separate instruments from separate bodies.
Why the confidence is not higherZero hits for 'National Electrical Code' in the county code (controls passed) and no electrical permit line in the FY2026 fee schedule. Austin Energy's Solar Permitting Manual (published May 2026) states ALL solar DG in AE territory requires an Auxiliary Power EP and that projects outside Austin city limits 'do not require any CoA building permits'. Deducted 15 because for the non-Austin-Energy parts of the county (co-op territory) I could not confirm the equivalent utility permit route this run.
utility permitting manual checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Green-Power/Solar/AustinEnergy_SolarPermittingManual.pdf
Q5 Who is allowed to pull the electrical permit? Core Who may apply
Licensed electrician — in Austin Energy territory. 'All solar PV systems require an Auxiliary Power electrical permit to be pulled by a licensed electrician. Homeowner exemptions are NOT allowed for solar projects.' Travis County itself imposes no such rule because it issues no electrical permit; its development permit is applied for by the owner/applicant.
Why the confidence is not higherVerbatim from Austin Energy Distribution Interconnection Guide rev. 14.0 (footer dated 31 March 2025), Section C. Deducted 15 because this is a utility-territory rule, not a county rule, and does not reach co-op-served parts of the unincorporated county.

Q6 Must the contractor be registered with this authority before applying? Core Who may apply
No — Travis County does not require contractor registration for the development permit. (In Austin Energy territory, Vendor Registration with the City of Austin IS required before an Auxiliary Power EP application can be submitted.)
Why the confidence is not higherThe county's 8-step solar process and its 'Gather Required Information' list ask only for address, TCAD legal description/PID/lot/block/phase, start date and estimated cost — no contractor registration step, and no registration page exists under TNR Development Services. Confidence held at 70 because this is proved by absence across the county's process pages rather than by a positive statement. The Austin Energy half is quoted directly from the Solar Permitting Manual p.1.

Q7 Is a homeowner permitted to self-install and self-permit? Who may apply
For the county development permit — yes, the property owner applies. For the electrical work in Austin Energy territory — no: 'Homeowner exemptions are NOT allowed for solar projects.'
Why the confidence is not higherThe AE half is a verbatim prohibition from the DIG rev. 14.0. The county half is inference from the application requirements (owner/applicant details, TCAD property ID) with no licensing requirement anywhere in Ch. 464 or the solar page.

Q8 What documents make up a complete submittal? Core Submittal package
County: (a) address; (b) TCAD legal description — Property ID (PID), lot, block, phase and section; (c) proposed construction start date; (d) estimated cost of construction; (e) a site plan showing all proposed improvements, location of waterways, an ESC (erosion & sedimentation control) Plan, a Restoration Plan, location of all easements and setbacks, location of floodplain, and location of on-site sewage facilities where applicable. The separate PDF Residential Checklist is no longer uploaded — its questions are now built into the online application. Utility (Austin Energy): DGPA form, wire diagram / design packet, and a signed Interconnection Agreement (now mandatory for all residential DG).
Why the confidence is not higherBoth lists are itemised verbatim on the authority's Solar Permit page and in the Austin Energy Solar Permitting Manual 'Required Documents' section respectively.
published checklist / permit page checked 2026-08-28 https://www.traviscountytx.gov/tnr/development-services/apply-for-a-permit/residential-solar-permit
Q9 How many copies, and in what format? Submittal package
Electronic upload through the MyGovernmentOnline (MGOConnect) portal; no paper copies described in the current process. Note that Code 464.062 still says an applicant shall submit the application 'along with plans in triplicate, drawn to scale' — paper-era text the online process appears to have superseded.
Why the confidence is not higherDirect conflict between the county's current published process (all-online, checklist integrated into the application) and the unrepealed text of 464.062, which was last replaced 30 April 2019. I have not found a document that reconciles them, so the 'triplicate' clause may still be invoked at the desk.

Q11 Is a one-line / three-line diagram required? Core Drawings & calculations
No at county level — Travis County requires no one-line or three-line diagram (the term 'one-line' returns zero hits in the county code and the solar page's document list has no electrical drawing). Yes at utility level — Austin Energy requires a 'Wire diagram/design packet for the proposed system design' as a mandatory upload on every Auxiliary Power EP.
Why the confidence is not higherCounty absence proved by full-text code search with positive controls passing and by the county's own document list. Utility requirement is verbatim from the Solar Permitting Manual 'Required Documents'.

Q12 Are string and conductor calculations required? Drawings & calculations
Not required by the county. Austin Energy's inspection checklist requires that 'Module string configuration is designed per inverter manufacturer's string sizing calculations' and that overcurrent devices be sized per NEC 705.11/705.12 — checked at inspection rather than demanded as a submittal calculation.
Why the confidence is not higherThe AE checklist verifies the outcome; it does not explicitly demand a submitted calculation sheet, so this is a judgement about how the requirement bites. County side is a proved absence.

Q13 Is a structural PE stamp required, and at what threshold? Core Engineering & stamps
No structural PE stamp for a standard roof-parallel residential array. Travis County imposes none (Ch. 480 does not reach a rooftop array). In Austin Energy territory a PE seal IS required where modules are not mounted parallel to the roof surface, extend past the existing roof, are on a new separate structure (ground mount), are solar roof tiles, or the installation is commercial — and separately, all Energy Storage System plans must be sealed by a Texas-licensed PE.
Why the confidence is not higherThresholds are itemised in AE DIG rev. 14.0 §C.11.a and §C.10.b. Note the AE clause is framed 'when the customer is located inside City of Austin full- or limited-purpose jurisdiction' for the building-permit half, so for an unincorporated address the PE trigger comes through AE's own review rather than a City building permit — a distinction worth confirming with AE for a specific parcel.

Q14 Is an electrical PE stamp required, and at what threshold? Engineering & stamps
No electrical PE stamp for standard residential rooftop PV. AE's inspection checklist requires PE-sealed electrical plans only for commercial installations, modules on new structures, modules extending past the roof, modules not parallel to the roof, and solar roof tiles.
Why the confidence is not higherVerbatim from the AE DG/DER Inspection Checklist 'General' section. Deducted because it is a checklist item rather than a submittal rule stated in the permitting manual.

Q15 What does a residential solar permit cost? Core Fees
$149 per application for an 'A' Residential floodplain/development permit; $287 per application if a 'B' Residential permit applies (property in the special flood hazard area). Acreage does not change either figure. Additional residential review fees may attach: Permanent Water Quality Control $203/lot, Site Complexity – Environmental $187/application.
Why the confidence is not higherThe FY2026 Development Related Fees Schedule (effective 01/01/2026) has NO solar line item — the figures above are the residential development-permit fees the solar application would fall under. The published schedule also never defines the 'A' vs 'B' split; I inferred it from Code 464.069, which ties 'B' permits to buildings and structures within the flood hazard area. The Austin Energy Auxiliary Power EP fee is separate and is not published in the manual (it is auto-billed in AB+C after approval). Also note a NEW fee schedule takes effect 10/01/2026 with recategorised and changed fees.
published fee schedule checked 2026-08-28 https://www.traviscountytx.gov/images/health_human_services/Docs/DR-Fee_Schedule-Effective-0126.pdf
Q16 How is the fee calculated? Core Fees
Flat — 'per application', explicitly not varying with acreage for residential ('A' Residential <1 acre and >1 acre are both $149). Non-residential, by contrast, is valuation-based ($137 + $1.99 per $1,000 of construction valuation).
Why the confidence is not higherRead directly from the fee schedule table. Deducted because the schedule does not name solar, so the mapping of a solar application to the residential flat fee is inference from the county's instruction to file under 'Development (Residential)'.

No separate plan-check fee is listed for a residential development permit. There is an 'Additional Reviews Fee' (10% of the original fee where there is no change and under 6 months of non-activity, 100% after six months), a $245 Construction Plan Revisions fee, and optional Expedited Review (varies, plus 31.32% expedited review overhead).
Why the confidence is not higherRead from the fee schedule; 'no separate plan-check fee' is an absence proved by reading the whole three-page schedule, not a positive statement.

Where we lookedTravis County Solar Permit page (all 8 steps), Development Services page, Permitting Center page, the FY2026 Development Related Fees Schedule, and Travis County Code 464.061–464.069 (the whole permit-process division). Code 464.066 lists the factors the Floodplain Administrator weighs in granting or denying a permit but sets no time limit. No stated plan-review turnaround exists for a residential development permit. The county's own Camino requirements tool and the MGOConnect project-type-details pages are single-page apps behind a login and returned no server-rendered content. Austin Energy's Solar Permitting Manual likewise states no review turnaround for the Auxiliary Power EP.

Q22 Which utility handles interconnection here? Core Utility interconnection
Split by address — there is no single utility for unincorporated Travis County. Austin Energy serves a large share: its territory is ~437 square miles, 'most of that area falls within Travis County', only 'about half of our service area is within the Austin city limits', and it names Travis County and Del Valle (unincorporated) among the areas served. The remainder of the unincorporated county is served by electric cooperatives (Pedernales EC to the west/north, Bluebonnet EC to the east) — which I could NOT confirm from their own sources in this run.
Why the confidence is not higherThe Austin Energy half is quoted from Austin Energy's own service-area page and is solid. The co-op half is not sourced: pec.coop refused the TLS handshake from this environment on every attempt (SSLV3_ALERT_HANDSHAKE_FAILURE) and bluebonnet.coop's about/service-area pages name '14 Central Texas counties' without listing them. Confirm the serving utility per address before relying on any utility-level answer below.
utility service-area page checked 2026-08-28 https://austinenergy.com/about/company-profile/electric-system/service-area-map
Q23 Where does the utility sit in the sequence? Core Utility interconnection
Before permit (utility gates the permit). In Austin Energy territory a signed Interconnection Agreement is now required for ALL residential DG projects and must be reviewed and approved by AE staff before the Auxiliary Power EP can be activated. AE also runs a DG Planning Application / Transformer Capacity review where DG output (solar + ESS) is ≥25 kW-ac, and a DG Plan Review whenever an ESS is included. The county development permit has no utility dependency.
Why the confidence is not higherSequenced explicitly in the Austin Energy Solar Permitting Manual (published May 2026), 'Austin Energy Reviews may also be applicable prior to permit Activation'. Deducted because the county-side independence is inferred from the absence of any utility step in the county's 8-step process rather than stated.

Q24 Is a HOA or architectural approval required first? Overlays & special cases
No. Travis County does not require HOA or architectural approval as a precondition of the development permit; it is not a step in the county's published process and no such requirement appears in the code.
Why the confidence is not higherProved by absence: 'homeowners association' returns 10 hits in the county code, all in subdivision/private-street/parkland contexts, none conditioning a development permit. Private deed restrictions may still bind the homeowner — the county code expressly says it does not 'repeal, abrogate, or impair … deed restrictions'. Kept at 65 because this is an absence, not a statement.

Q25 Is there a historic-district review? Overlays & special cases
No historic-district review. Travis County has no zoning or historic-district authority over private property in the unincorporated area.
Why the confidence is not higherProved by absence with controls passing: the 20 'historic' hits in the county code are the floodplain definition of 'Historic structure' (an NFIP insurance-rating term) and references to public park facilities — none creates a review. The county's own permit pages list no historic review step. Kept at 70 because it rests on absence rather than an affirmative disclaimer.

No wind or windstorm certification required by Travis County.
Why the confidence is not higher'windstorm' returns ZERO hits in the entire Travis County Code with positive controls passing ('electrical' 16, 'building' 163) and the fabricated control returning 0. Held at 60 because I could not reach the Texas Department of Insurance to confirm Travis is outside the designated catastrophe area (TDI windstorm certification is a coastal-county regime and Travis is inland) — that half is unsourced this run. Austin Energy's inspection checklist does require that the 'Array is capable of sustaining wind requirements', but sets no certification.

Q27 Is a Specific Use Permit or Council approval ever required? Overlays & special cases
No Specific Use Permit or Commissioners Court approval is required for residential rooftop PV. Travis County has no zoning power. The only Commissioners Court route in this area is a floodplain variance under Code Ch. 464 Subchapter C Division 4, which a rooftop array would not normally engage.
Why the confidence is not higherAbsence across the county code plus the structure of Ch. 464 (variances are floodplain variances only). Kept at 70 because it is inference from what the code contains rather than an explicit statement that no SUP exists.

Q28 Is there a system-size cap on residential generation? Overlays & special cases
No county cap on residential generation size. At utility level in Austin Energy territory, a system is not capped but crossing 25 kW-ac (solar + ESS combined) triggers an additional Distributed Generation Planning Application and/or Transformer Capacity review before the permit can activate.
Why the confidence is not higherCounty side is a proved absence (no size provision anywhere in the code; zero solar/photovoltaic provisions). The 25 kW-ac trigger is stated verbatim in the AE Solar Permitting Manual. Deducted because a review trigger is not a cap and the manual does not say what happens if capacity is unavailable.

Build to the code editions actually in force here
The NEC edition a jurisdiction enforces is often a cycle behind the newest one published, and local amendments sit on top of it. Rapid shutdown, conductor sizing and labelling all change between editions, so the edition in force is the first thing to establish, not the last.
- Which NEC edition is in force? Other — Travis County adopts NO edition of the NEC. In Austin Energy territory the installation is nevertheless built and inspected to the NEC: AE's Distribution Interconnection Guide rev. 14.0 was a major revision to 'better align with City of Austin adoption of NEC 2023 code', and its rules cite NEC 2023-era articles (690.12, 690.15, 690.31(D)(2), 705.10, 705.11, 705.12, 706.15, 230.67). 75% · utility interconnection guide + code search (absence)
- Which building code edition is in force? For NEW residential construction only (a new single-family house or duplex on a vacant lot, or an addition increasing square footage or value by more than 50%): the builder's choice of either the International Residential Code as published on 1 May 2008, OR the IRC edition applicable inside the City of Austin corporate limits. A rooftop PV array on an existing home falls outside this definition, so no building code edition applies to it. Where a municipality has adopted a building code in its ETJ, that municipal code controls and Ch. 480 has no effect there. 90% · adopting ordinance
- Which fire code edition is in force? 2021 International Fire Code (including Appendix Chapters B, C, D, F, H and I) with local amendments, effective 1 January 2026. It applies ONLY to commercial establishments, public buildings and multifamily residential dwellings of more than three units — a one- or two-family dwelling is not a 'Building' under Ch. 201, so the fire code creates no permit or standard for residential rooftop PV. 95% · adopting ordinance (county-hosted PDF)
- Are there local amendments to any of the above? Yes. Code 201.064 'Amendments to the 2021 International Fire Code' contains extensive local amendments (including a rewritten IFC 102.1 scope). Ch. 480 modifies IRC applicability rather than amending the IRC text. None of these amendments mentions solar or photovoltaics. 90% · adopting ordinance
- What is the installation judged against? At county level: only floodplain and land-development standards — Code Ch. 464 (floodplain management), Ch. 482 (development regulations, incl. erosion/sedimentation control and water quality). Nothing electrical or structural. At utility level in Austin Energy territory: the NEC, the Austin Energy Design Criteria Manual, and the AE Distribution Interconnection Guide, verified against AE's published DG/DER Inspection Checklist. 80% · authority permit page
-
Fire access, setbacks and pathways
Ridge setbacks and roof access pathways are fire-service requirements and they constrain the array layout. They are the most common cause of a redesign after the fire department comments on a plan set.
- What ridge setback and access pathways are required? No ridge setback or access pathway dimensions are set by Travis County for a one- or two-family dwelling. The county fire code (2021 IFC + amendments) does not reach single-family dwellings at all, and contains zero solar provisions. Austin Energy's checklist says only 'Roof perimeter access meets fire code' and directs installers to 'Check with your local Fire Department to ensure solar panel installation meets fire code requirements', pointing to the ICC Texas codes site — i.e. it defers without adopting a dimension. 75% · adopting ordinance + utility guide
-
Rapid shutdown
Which rapid-shutdown rule applies follows directly from the NEC edition in force, and the initiation device has to be at a location the fire service can reach and identify. This is inspected, and it is labelled.
- Is rapid shutdown required, and to which NEC edition? Yes in Austin Energy territory — 'All installations submitted for approval shall incorporate a rapid shutdown feature per NEC Article 690.12: Voltage below 30 volts within 30 seconds of rapid shut down initiation', and 'A rapid shutdown label shall be installed in accordance with NEC Article 690'. Travis County itself imposes no rapid-shutdown requirement (zero hits in the county code). 85% · utility interconnection guide
-
Labels and placards
The NEC sets a baseline for permanent markings at the service equipment and the disconnecting means. On top of that, an authority may specify its own wording, and the utility may specify more again. Where any of them writes its own text, a generic off-the-shelf label set will not pass — this is the detail most often fixed on a return visit.
- Which placards does this authority require at the service equipment? Travis County requires NO placards. All placard requirements come from the utility. Austin Energy requires at the service equipment: (1) a directory/plaque of all DG/DER disconnects and sources on site INCLUDING contact information, per NEC 690.31(D)(2) and/or 705 and AE Design Criteria Manual 1.9.1.7; (2) a rapid shutdown label per NEC Article 690; (3) the plaque must also include information on any standby systems or energy storage system per NEC 705.10; (4) where a PV aggregate panel is installed, a label on that panel; (5) where an ESS enclosure contains both backed-up and non-backed-up circuits, a feed-through warning label; (6) an AE-supplied battery-recycling QR-code label on the ESS; (7) conduit carrying DC PV output conductors labelled every 10 feet per NEC 690.31(D)(2); (8) each meter enclosure or service disconnect permanently marked with the address of its occupancy/unit; (9) disconnect switches labelled per NEC 690.15. 90% · utility interconnection guide
- Does the authority specify placard wording of its own? Travis County — No, it specifies no placard wording of its own. Austin Energy — Yes, for two labels it dictates exact wording: 'PV AGGREGATE PANEL: DO NOT ADD, REMOVE OR RELOCATE LOADS' on a PV aggregate panel, and 'THIS ENCLOSURE CONTAINS FEED THROUGH CONDUCTORS THAT MAY BE ENERGIZED WHEN THE DISCONNECT IS DE-ENERGIZED' where an enclosure contains backed-up and non-backed-up circuits. All other AE placards are specified by reference to the NEC rather than by wording. 90% · utility interconnection guide
- Is a site plan / facility map placard required, and what must it show? Yes at utility level, by reference. Austin Energy requires a directory/plaque of ALL DG/DER disconnects and sources on site, including contact information, per NEC 690.31(D)(2) and/or 705, and it 'must also include information on any standby systems or energy storage system in accordance with NEC Article 705.10'. For utility-side interconnections a directory plaque is required at the point of interconnection, at each disconnecting means, AND on the roof by the PV array. Travis County requires nothing. 85% · utility interconnection guide
- Does the UTILITY specify placards beyond the AHJ's? Yes — and in this jurisdiction the utility's placards are the ONLY placards in play, because Travis County specifies none. See Q38 for the full Austin Energy list, including two AE-specific labels that have no NEC equivalent (the PV aggregate panel label and the AE-supplied battery-recycling QR-code label on the ESS). 90% · utility interconnection guide
- Where must the labels be placed? Grouped at the service equipment. Austin Energy requires the following to be grouped: Directory Plaque, Main Service Disconnect, Billing Meter, PV Meter, Main PV AC Disconnect, and ESS Main Disconnect. Where grouping is not practical, a meter variance must be approved BEFORE installation (submit to AEAdvancedMeteringEngineering@austinenergy.com, including 'a proposed placard language describing the alternative location'). Exceptions: an ESS directory plaque must be installed by the ESS equipment if that equipment is not grouped, not to exceed 20 feet without an approved variance; for utility-side interconnections, plaques go at the point of interconnection, at each disconnecting means, and on the roof by the array; DC PV conduit labels go every 10 feet along the run. 90% · utility interconnection guide
-
Disconnect, storage and listed equipment
Where the AC disconnect must sit relative to the meter is usually the utility's rule, not the building department's. Battery storage frequently carries its own permit, its own inspection and its own fire conditions.
- Where must the AC disconnect be, relative to the meter? Austin Energy: the Main PV AC Disconnect must be a manual load-break switch with visible blades (no toggle switches), grouped with the metering equipment and other switches, and installed ON THE SOLAR SIDE of the PV meter so the meter remains energised while the PV system is disconnected (except at 480 V, where an additional disconnecting means is required between the PV meter and the interconnection). It must be readily accessible to AE personnel at all times and capable of being locked in the open position with an AE padlock; maintain a 3-foot radius from gas meters, regulators and relief valves; neutral broken and isolated in both the main PV AC disconnect and the PV meter; service-rated equipment required; inverter output conductors terminate on the load side, line-side conductors run to the line side of the PV meter socket; for supply-side taps the fusible disconnect handle rating is minimum 60 A. Travis County specifies nothing. 95% · utility interconnection guide
- Must equipment be on a specific approved list? Yes, at utility level. Austin Energy requires: all equipment UL listed and 'properly labeled per the NEC and the Austin Energy Design Criteria'; solar PV inverters certified to UL1741, UL1699B and UL1547 AND listed by the California Energy Commission; ESS inverters certified to UL1741 or UL9540 and listed for utility interaction; ESS certified to UL1973 (UL9540 for electrochemical cells, UL1642 lithium-ion, UL1989 lead-acid); and the meter socket must be 'approved by Austin Energy for use (i.e., socket is listed on AE website or has written approval from AE Distribution Metering)'. Travis County maintains no approved list. 90% · utility interconnection guide
- Are batteries permitted, and under what conditions? Permitted. Travis County imposes no condition (zero battery/ESS provisions in the county code, and the fire code does not reach single-family dwellings). Austin Energy conditions: ESS plans sealed by a Texas-licensed PE; ESS certified to UL1973, with UL9540 for electrochemical cells, UL1642 lithium-ion, UL1989 lead-acid; if installed in a residential dwelling the ESS must be listed and labeled for the purpose; residential ESS exceeding 1 kWh must comply with the prevailing International Residential Code (2021), especially IRC 2021 §R328; approved vehicle impact protection where installed in a garage vehicle drive path; a disconnecting means per NEC 706.15 grouped with the main service and within sight of the ESS, installed within 5 feet of the main panel; and at inspection batteries must hold charge without damage. Note AE's Fire-Department threshold (individual units >20 kWh, or installations >80 kWh) is written as applying 'Within the City of Austin' only. 85% · utility interconnection guide
- Is there a separate ESS permit or inspection? No separate ESS permit. Austin Energy's manual states solar and batteries 'can be included together' on a single Residential Auxiliary Power Electrical Permit. Including an ESS does, however, trigger an additional Austin Energy Distributed Generation Plan Review (DGPR) before permit activation, and ESS plans must be PE-sealed. Travis County requires no ESS permit at all. 85% · utility permitting manual
- Is a ground mount treated as a structure? Mixed, and the distinction matters. A ground mount IS 'development' under Travis County Code 464.031 ('any man-made change to improved or unimproved real estate, including … the construction of buildings or other structures') and therefore needs a development permit. But it is NOT a 'structure' for floodplain purposes: 464.031 defines 'Structure' as 'a walled and roofed building that is principally above ground', which a ground-mounted array is not. At utility level, Austin Energy treats a ground mount as needing only a Residential Auxiliary Power EP when outside Austin city limits — 'projects installed WITHIN the ETJ, or OUTSIDE of Austin city limits do not require any CoA building permits' — though PE-sealed plans are required for modules built on a new and separate structure. 75% · ordinance definitions + utility permitting manual
- Is there a local rule on service upgrades or busbar sizing? No county rule. Austin Energy: overcurrent protection sized correctly for the main panel busbar per NEC 705.11 (supply-side connections) or NEC 705.12 (backfeed breaker); for supply-side taps the fusible disconnect handle rating must be a minimum of 60 A with fuse size calculated per NEC; a Type 1 or Type 2 surge protective device is required, sized for the service entrance per NEC 230.67. Service-side work needs a separate 'Upgrade' EP with an ESPA form; customer-side work needs a 'Repair' EP. 85% · utility interconnection guide
- Is a specific mounting system or attachment spacing required? No county rule on mounting system or attachment spacing. Austin Energy's inspection checklist requires: stainless steel fasteners on modules and racking; mounting system meets structural requirements (roof can sustain the extra weight; array capable of sustaining wind requirements); all roof penetrations flashed; all building penetrations sealed and fire resistance maintained; modules not modified in a way that voids listing or warranty; conductors properly secured above the roof surface with no wires touching the roof. 80% · utility inspection checklist
20 questions answered against Travis County’s own published documents
Q29 Which NEC edition is in force? Core Code editions in force
Other — Travis County adopts NO edition of the NEC. In Austin Energy territory the installation is nevertheless built and inspected to the NEC: AE's Distribution Interconnection Guide rev. 14.0 was a major revision to 'better align with City of Austin adoption of NEC 2023 code', and its rules cite NEC 2023-era articles (690.12, 690.15, 690.31(D)(2), 705.10, 705.11, 705.12, 706.15, 230.67).
Why the confidence is not higherThe county absence is hard-proved: 'National Electrical Code' returns ZERO hits in the county code with positive controls passing. The NEC 2023 attribution is the CITY OF AUSTIN's adoption, applied to unincorporated addresses only through Austin Energy's interconnection requirements and inspection — it is not a Travis County adoption and would not bind a co-op-served parcel. That indirection is why this is 75 and not higher.

Q30 Which building code edition is in force? Core Code editions in force
For NEW residential construction only (a new single-family house or duplex on a vacant lot, or an addition increasing square footage or value by more than 50%): the builder's choice of either the International Residential Code as published on 1 May 2008, OR the IRC edition applicable inside the City of Austin corporate limits. A rooftop PV array on an existing home falls outside this definition, so no building code edition applies to it. Where a municipality has adopted a building code in its ETJ, that municipal code controls and Ch. 480 has no effect there.
Why the confidence is not higherVerbatim from Travis County Code 480.002, 480.003 and 480.004 in the county-hosted chapter PDF. Deducted 10 only because the '2008 IRC or Austin's current IRC' option is unusual enough to be worth confirming with the permit desk for an edge case.

Q31 Which fire code edition is in force? Code editions in force
2021 International Fire Code (including Appendix Chapters B, C, D, F, H and I) with local amendments, effective 1 January 2026. It applies ONLY to commercial establishments, public buildings and multifamily residential dwellings of more than three units — a one- or two-family dwelling is not a 'Building' under Ch. 201, so the fire code creates no permit or standard for residential rooftop PV.
Why the confidence is not higherThe county-hosted Chapter 201 PDF carries the 2021 Fire Code adoption at 201.003(c-1), 201.006 and the amended IFC 102.1 scope. The Fire Marshal's own page states 'Effective January 1, 2026, Travis County and all county agencies will implement and enforce the 2021 Fire Code'. WARNING: the third-party code library (enCodePlus) still shows only the 2015 Fire Code for Ch. 201 — it is stale, and the county-hosted PDF is the current text. The Fire Marshal's FAQ page is ALSO stale, still answering 'International Fire Code 2015 ed.' for inspection standards.

Q32 Are there local amendments to any of the above? Core Code editions in force
Yes. Code 201.064 'Amendments to the 2021 International Fire Code' contains extensive local amendments (including a rewritten IFC 102.1 scope). Ch. 480 modifies IRC applicability rather than amending the IRC text. None of these amendments mentions solar or photovoltaics.
Why the confidence is not higherRead from the county-hosted Ch. 201 PDF. Controls run on that extracted text: 'fire' 339 hits, 'zzqqx' 0 hits, 'solar' 0, 'photovoltaic' 0, 'PV' 0 — so the absence of solar provisions in the amendments is proved, not assumed.

Q33 What is the installation judged against? Core Electrical
At county level: only floodplain and land-development standards — Code Ch. 464 (floodplain management), Ch. 482 (development regulations, incl. erosion/sedimentation control and water quality). Nothing electrical or structural. At utility level in Austin Energy territory: the NEC, the Austin Energy Design Criteria Manual, and the AE Distribution Interconnection Guide, verified against AE's published DG/DER Inspection Checklist.
Why the confidence is not higherCounty side from the 'References & Code' block of the county's own Solar Permit page, which lists exactly three chapters — 464 Floodplain Management, 480 Residential Construction Standards and 482 Development Regulations — plus TCEQ stormwater rules, and nothing else. Deducted because Ch. 480 is listed on that page even though its own definitions exclude a rooftop array, so the county page over-lists.

Q34 Is there a local rule on service upgrades or busbar sizing? Electrical
No county rule. Austin Energy: overcurrent protection sized correctly for the main panel busbar per NEC 705.11 (supply-side connections) or NEC 705.12 (backfeed breaker); for supply-side taps the fusible disconnect handle rating must be a minimum of 60 A with fuse size calculated per NEC; a Type 1 or Type 2 surge protective device is required, sized for the service entrance per NEC 230.67. Service-side work needs a separate 'Upgrade' EP with an ESPA form; customer-side work needs a 'Repair' EP.
Why the confidence is not higherItemised in the AE DIG rev. 14.0 §C.4 and the Appendix C inspection checklist. Deducted because these are utility-territory requirements, not county rules.

Q35 Is a specific mounting system or attachment spacing required? Structural & mounting
No county rule on mounting system or attachment spacing. Austin Energy's inspection checklist requires: stainless steel fasteners on modules and racking; mounting system meets structural requirements (roof can sustain the extra weight; array capable of sustaining wind requirements); all roof penetrations flashed; all building penetrations sealed and fire resistance maintained; modules not modified in a way that voids listing or warranty; conductors properly secured above the roof surface with no wires touching the roof.
Why the confidence is not higherVerbatim from AE DIG Appendix C, 'Solar PV Module Array' and 'General'. No numeric attachment spacing is specified anywhere — the requirement is performance-stated, which is why this is not higher.
utility inspection checklist checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Contractors/AE_DG_Interconnection_Guide.pdf
Q36 What ridge setback and access pathways are required? Core Fire pathways & setbacks
No ridge setback or access pathway dimensions are set by Travis County for a one- or two-family dwelling. The county fire code (2021 IFC + amendments) does not reach single-family dwellings at all, and contains zero solar provisions. Austin Energy's checklist says only 'Roof perimeter access meets fire code' and directs installers to 'Check with your local Fire Department to ensure solar panel installation meets fire code requirements', pointing to the ICC Texas codes site — i.e. it defers without adopting a dimension.
Why the confidence is not higherThe county absence is hard-proved (0 hits for solar/photovoltaic/PV in the current Ch. 201 text with controls passing; scope limited to commercial/public/multifamily>3). The residual risk is that the local Emergency Services District fire department applies IFC 1204/605.11 pathway rules as a matter of practice on inspection; the Fire Marshal retains independent Local Government Code Ch. 352 authority to inspect for fire and life-safety hazards regardless of Ch. 201. I could not test that practice from published sources.

Q37 Is rapid shutdown required, and to which NEC edition? Core Rapid shutdown
Yes in Austin Energy territory — 'All installations submitted for approval shall incorporate a rapid shutdown feature per NEC Article 690.12: Voltage below 30 volts within 30 seconds of rapid shut down initiation', and 'A rapid shutdown label shall be installed in accordance with NEC Article 690'. Travis County itself imposes no rapid-shutdown requirement (zero hits in the county code).
Why the confidence is not higherBoth sentences are verbatim from AE DIG rev. 14.0 §C.12 and §C.1.a. The NEC edition is not named in the clause — the guide's revision history ties the document to NEC 2023 via the City of Austin's adoption. Deducted for that and because the rule is utility-territory, not countywide.

Q38 Which placards does this authority require at the service equipment? Core Labels Signage & labelling
Travis County requires NO placards. All placard requirements come from the utility. Austin Energy requires at the service equipment: (1) a directory/plaque of all DG/DER disconnects and sources on site INCLUDING contact information, per NEC 690.31(D)(2) and/or 705 and AE Design Criteria Manual 1.9.1.7; (2) a rapid shutdown label per NEC Article 690; (3) the plaque must also include information on any standby systems or energy storage system per NEC 705.10; (4) where a PV aggregate panel is installed, a label on that panel; (5) where an ESS enclosure contains both backed-up and non-backed-up circuits, a feed-through warning label; (6) an AE-supplied battery-recycling QR-code label on the ESS; (7) conduit carrying DC PV output conductors labelled every 10 feet per NEC 690.31(D)(2); (8) each meter enclosure or service disconnect permanently marked with the address of its occupancy/unit; (9) disconnect switches labelled per NEC 690.15.

Nothing published by this authority.
Where we lookedAustin Energy Distribution Interconnection Guide rev. 14.0 in full (3,969 lines extracted with pdftotext -layout) — searched for 'letter', 'lettering', 'font', 'inch high', 'characters'; the only hits are 'letter of authorization', 'letter releasing the DGPA' and 'Design Letter'. No letter height, colour or material is specified. The DIG defers to Austin Energy Design Criteria Manual 1.9.1.7, which I did not retrieve this run. Also searched the whole Travis County Code: 'placard' returns 3 hits (public notice, general rules, other restrictions), none electrical, with positive controls passing and 'zzqqx' returning 0.
Q41 Is a site plan / facility map placard required, and what must it show? Core Labels Signage & labelling
Yes at utility level, by reference. Austin Energy requires a directory/plaque of ALL DG/DER disconnects and sources on site, including contact information, per NEC 690.31(D)(2) and/or 705, and it 'must also include information on any standby systems or energy storage system in accordance with NEC Article 705.10'. For utility-side interconnections a directory plaque is required at the point of interconnection, at each disconnecting means, AND on the roof by the PV array. Travis County requires nothing.
Why the confidence is not higherVerbatim from AE DIG rev. 14.0 §C.1. AE does not itself prescribe what the site plan/facility map must depict beyond the NEC 705.10 reference, so the content spec is the NEC's, not the utility's — hence not higher.

Q43 Where must the labels be placed? Core Labels Signage & labelling
Grouped at the service equipment. Austin Energy requires the following to be grouped: Directory Plaque, Main Service Disconnect, Billing Meter, PV Meter, Main PV AC Disconnect, and ESS Main Disconnect. Where grouping is not practical, a meter variance must be approved BEFORE installation (submit to AEAdvancedMeteringEngineering@austinenergy.com, including 'a proposed placard language describing the alternative location'). Exceptions: an ESS directory plaque must be installed by the ESS equipment if that equipment is not grouped, not to exceed 20 feet without an approved variance; for utility-side interconnections, plaques go at the point of interconnection, at each disconnecting means, and on the roof by the array; DC PV conduit labels go every 10 feet along the run.
Why the confidence is not higherAll quoted from AE DIG rev. 14.0 §C 'General System Requirements' and §C.1. Deducted because the AE Design Criteria Manual sections it cites (1.9.1.7, 1.9.3.1.j) were not retrieved and may add mounting-height detail.

Q44 Must equipment be on a specific approved list? Equipment listing
Yes, at utility level. Austin Energy requires: all equipment UL listed and 'properly labeled per the NEC and the Austin Energy Design Criteria'; solar PV inverters certified to UL1741, UL1699B and UL1547 AND listed by the California Energy Commission; ESS inverters certified to UL1741 or UL9540 and listed for utility interaction; ESS certified to UL1973 (UL9540 for electrochemical cells, UL1642 lithium-ion, UL1989 lead-acid); and the meter socket must be 'approved by Austin Energy for use (i.e., socket is listed on AE website or has written approval from AE Distribution Metering)'. Travis County maintains no approved list.
Why the confidence is not higherItemised in AE DIG rev. 14.0 §C and Appendix C 'Inverters' / 'Energy Storage Systems' / 'Meters'. The CEC-listing requirement and the AE meter-socket list are genuine approved-list requirements, not just listing standards.

Q45 Are batteries permitted, and under what conditions? Core Battery / ESS
Permitted. Travis County imposes no condition (zero battery/ESS provisions in the county code, and the fire code does not reach single-family dwellings). Austin Energy conditions: ESS plans sealed by a Texas-licensed PE; ESS certified to UL1973, with UL9540 for electrochemical cells, UL1642 lithium-ion, UL1989 lead-acid; if installed in a residential dwelling the ESS must be listed and labeled for the purpose; residential ESS exceeding 1 kWh must comply with the prevailing International Residential Code (2021), especially IRC 2021 §R328; approved vehicle impact protection where installed in a garage vehicle drive path; a disconnecting means per NEC 706.15 grouped with the main service and within sight of the ESS, installed within 5 feet of the main panel; and at inspection batteries must hold charge without damage. Note AE's Fire-Department threshold (individual units >20 kWh, or installations >80 kWh) is written as applying 'Within the City of Austin' only.
Why the confidence is not higherAll from AE DIG rev. 14.0 §C.10 and Appendix C. Deducted because AE's ESS fire-approval threshold is expressly city-limited and the guide is silent on what, if anything, replaces it for an unincorporated address — an installer should ask AE and the local ESD before siting a large ESS.
utility interconnection guide checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Contractors/AE_DG_Interconnection_Guide.pdf
Q46 Is there a separate ESS permit or inspection? Battery / ESS
No separate ESS permit. Austin Energy's manual states solar and batteries 'can be included together' on a single Residential Auxiliary Power Electrical Permit. Including an ESS does, however, trigger an additional Austin Energy Distributed Generation Plan Review (DGPR) before permit activation, and ESS plans must be PE-sealed. Travis County requires no ESS permit at all.
Why the confidence is not higherBoth statements verbatim from the AE Solar Permitting Manual (published May 2026). Deducted because the manual separately notes that if an ESS is on the solar side of the PV meter a second PV meter is required, which brings its own metering process.
utility permitting manual checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Green-Power/Solar/AustinEnergy_SolarPermittingManual.pdf
Q47 Is a ground mount treated as a structure? Core Ground mount
Mixed, and the distinction matters. A ground mount IS 'development' under Travis County Code 464.031 ('any man-made change to improved or unimproved real estate, including … the construction of buildings or other structures') and therefore needs a development permit. But it is NOT a 'structure' for floodplain purposes: 464.031 defines 'Structure' as 'a walled and roofed building that is principally above ground', which a ground-mounted array is not. At utility level, Austin Energy treats a ground mount as needing only a Residential Auxiliary Power EP when outside Austin city limits — 'projects installed WITHIN the ETJ, or OUTSIDE of Austin city limits do not require any CoA building permits' — though PE-sealed plans are required for modules built on a new and separate structure.
Why the confidence is not higherThe two county definitions are quoted verbatim and genuinely pull in opposite directions; which one the permit desk applies to a ground mount is not published anywhere I could find. The AE half is verbatim from the Solar Permitting Manual.

Q48 Where must the AC disconnect be, relative to the meter? Core Utility equipment
Austin Energy: the Main PV AC Disconnect must be a manual load-break switch with visible blades (no toggle switches), grouped with the metering equipment and other switches, and installed ON THE SOLAR SIDE of the PV meter so the meter remains energised while the PV system is disconnected (except at 480 V, where an additional disconnecting means is required between the PV meter and the interconnection). It must be readily accessible to AE personnel at all times and capable of being locked in the open position with an AE padlock; maintain a 3-foot radius from gas meters, regulators and relief valves; neutral broken and isolated in both the main PV AC disconnect and the PV meter; service-rated equipment required; inverter output conductors terminate on the load side, line-side conductors run to the line side of the PV meter socket; for supply-side taps the fusible disconnect handle rating is minimum 60 A. Travis County specifies nothing.
Why the confidence is not higherAll quoted from AE DIG rev. 14.0 §C.7 'Main PV AC Disconnect' and confirmed against the Appendix C inspection checklist 'AC Disconnect' section.

Inspection 5 steps · 14 questions
-
Book it
Booking is a portal, a phone call or an email depending on the authority, and the notice required is rarely zero. Book before the work is finished rather than after — the lead time, not the work, is usually what sets the date.
- How is an inspection booked? Portal, at utility level — Austin Energy solar inspections are requested through the Austin Build + Connect (AB+C) portal, 'My Inspections' tab, and may only be requested for permits in 'Active' status. Travis County performs no inspection of residential rooftop PV; where a floodplain 'B' permit does trigger a county inspection, the permittee notifies the Floodplain Administrator directly (Code 464.069), and county development-permit communication otherwise runs through MyGovernmentOnline. 85% · utility department page + county ordinance
- How much notice is required? Austin Energy: no fixed notice period is published; after a request is submitted the AE Solar Inspections team schedules it and the contractor receives an email with the date/time 'usually within 3 business days'. Travis County (floodplain 'B' permits only): 'The permittee shall notify the Floodplain Administrator 48 hours before construction is ready for the above inspection.' 85% · utility permitting manual + county ordinance
- Are same-day or AM/PM windows offered? No same-day inspections. Austin Energy warns explicitly: 'Although the page may state that the inspection is scheduled for the same day, this is FALSE. The inspection is not yet scheduled and will not be performed on the same day.' Contractors supply their availability and contact details with the request; no AM/PM window system is published. 85% · utility permitting manual
-
Know who turns up
Some authorities inspect their own solar work; some delegate it, and a few do not inspect the PV equipment itself at all. Who is coming determines what they will look at.
- Does this AHJ perform its own final solar inspection? No / Delegated. Travis County does NOT perform a final solar inspection. Its own Solar Permit page has an 8-step process with no inspection step at all — it ends at 'Receive the Permit' and 'Post the permit somewhere visible from the public right of way'. Contrast the county's Single-Family Home, Addition and Remodel permit pages, which all state inspections 'must be performed by a licensed 3rd party inspector'. The DG inspection is performed by the utility: in Austin Energy territory, by the AE Solar Inspections team. 85% · authority permit pages + ordinance
- If delegated, to whom? Two delegations. (1) Electrical / DG inspection → the serving utility; in Austin Energy territory, Austin Energy Solar Inspections (solarinspections@austinenergy.com, 512-482-5346). (2) Building-code inspection where Ch. 480 applies at all (new SFH/duplex or >50% addition) → a third party contracted by the builder: a licensed engineer, registered architect, TREC-licensed professional inspector, a municipally-employed TSBPE-licensed plumbing inspector, a building inspector employed by a political subdivision, or an ICC-certified residential combination inspector. 85% · adopting ordinance + utility department page
-
Work the stages in order
A rough-in or mid-roof inspection, where one is required, has to happen before the work it covers is closed up. Missing a stage means opening something back up, and it is the most expensive kind of correction.
- Which inspections are required, and in what order? Austin Energy sequence: (1) optional pre-construction meeting with an AE DG inspector (mandatory for commercial); (2) Rough inspection (301) where wiring will be covered before completion, and/or Temporary Power (304) and pre-wire final inspections where applicable; (3) all other related permits (Repair / Upgrade EPs) must reach 'Final' status; (4) Final solar inspection (305); (5) AE Distribution Metering Operations reviews and approves the as-built revenue and solar meter installation and installs the solar meter(s); (6) permit moves to 'Final' = Permission to Operate. Where a CT meter is required, the CT meter inspection sits after a passed 304 Temporary and before the final 305 is requested. Travis County adds no inspection stages for rooftop PV. 90% · utility permitting manual + department page
- Is a rough-in or mid-roof inspection required? Yes, conditionally. Austin Energy: 'If any parts of the system (e.g., wiring) will be covered up before the installation is complete, request a Rough Inspection to have them reviewed first.' A separate Pre-Wire Final inspection applies where wiring is installed for a future solar installation (typically new construction), and a Pre-wire ONLY Auxiliary Power EP exists for that case. No mid-roof inspection is required. 90% · utility department page
-
Have the paperwork on site
The approved plan set, the permit, and the equipment listings should be on site and reachable. Inspectors routinely verify that installed equipment matches what was approved, and that the labels are the ones the plan set promised.
- Is there a published inspection checklist? Yes at utility level — Austin Energy publishes a 'DG/DER Inspection Checklist & Contractor Quick Reference Guide' as Appendix C of the Distribution Interconnection Guide, organised into General, Meters, Service Disconnect, Overcurrent Protection, Grounding and Bonding, AC Disconnect, Surge Protection, Inverters, Wiring, Raceways, Solar PV Module Array, Energy Storage Systems and System Performance Validation. No at county level — Travis County publishes no inspection checklist for solar (and performs no such inspection). 95% · utility inspection checklist
- What must be on site at inspection? County: the issued development permit must be posted somewhere visible from the public right of way on the work site before the project begins. Utility (Austin Energy): the Auxiliary Power EP must be in Active status with the permit address matching the installation address; all Upgrade or Repair EPs for the same property closed; the installation consistent with the electrical design drawings; and contractor contact details supplied for the day of inspection. Where equipment is not grouped, the approved meter variance must be in hand. 85% · authority permit page + utility guide
- Does the inspector verify labels and listings? Yes. Austin Energy's published DG/DER Inspection Checklist verifies both explicitly: 'All equipment has permanent labels'; 'All installed equipment is UL listed'; 'All meters, disconnects, and directory placard are grouped' (with 'Any equipment that cannot be grouped has a variance approval'); 'Conduit with DC PV output conductors is labeled every 10 feet, per NEC 690.31.D.2'; 'Meter socket is approved by Austin Energy for use'; and inverter certification/CEC listing checks. 95% · utility inspection checklist
-
Sign-off, and permission to operate
Passing gives you a final or an equivalent sign-off. That is not the same as permission to operate: PTO comes from the utility, and who tells the utility the inspection passed varies. A system left switched off for weeks is usually waiting on this handover.
- What is issued on pass? The operative sign-off is the utility's: the Auxiliary Power EP moves to 'Final' status once AE Distribution Metering Operations has approved the as-built revenue and solar meter installation and set the solar meter — 'At this point, the project is closed, and the customer has Permission to Operate (PTO)', confirmed by a PTO email. Travis County issues no final or CO for rooftop PV; a Certificate of Occupancy exists only for floodplain 'B' permit construction, and is literally 'a copy of the B permit with inspections noted or certification attached and bearing the words Certificates of Occupancy followed by the dated signature of the Floodplain Administrator'. 85% · utility permitting manual + county ordinance
- Who notifies the utility for PTO? Utility pulls. Nobody notifies Austin Energy — AE is already inside the process. AE Distribution Metering Operations reviews and approves the final as-built meter installation, installs the solar meter(s), updates the meter details on the permit and moves it to 'Final'; contractors and customers are then notified by email that PTO is granted. There is no AHJ-to-utility handoff because Travis County is not in the electrical chain at all. 90% · utility permitting manual
- Is there a re-inspection fee? Travis County: $200 per inspection after the initial free inspection (Inspections section of the FY2026 fee schedule); a separate $249 per corrective action report issuance & follow-up inspection applies to Permanent Water Quality Control non-compliance. Austin Energy: a re-review fee is charged for a 3rd DG Plan Review after two failures — the amount is not published in the manual. 70% · published fee schedule
- How are corrections issued and cleared? County: comments are issued inside the MyGovernmentOnline portal — 'If the County has provided comments on your application, action is required by you to address the comments. The review process will be paused until you have responded sufficiently to each comment.' Enforcement-stage problems come as a Notice of Violation and/or Stop Work Order, cleared through the county's 'How to Resolve a Violation' process. Utility: on a failed AE review the contractor receives an email from the permitting system with deficiencies and failure comments, also recorded in the AB+C permit workflow details page; reviewers can be contacted directly or via solarinspections@austinenergy.com. 85% · authority permit page + utility permitting manual
14 questions answered against Travis County’s own published documents
Q49 How is an inspection booked? Core Booking & scheduling
Portal, at utility level — Austin Energy solar inspections are requested through the Austin Build + Connect (AB+C) portal, 'My Inspections' tab, and may only be requested for permits in 'Active' status. Travis County performs no inspection of residential rooftop PV; where a floodplain 'B' permit does trigger a county inspection, the permittee notifies the Floodplain Administrator directly (Code 464.069), and county development-permit communication otherwise runs through MyGovernmentOnline.
Why the confidence is not higherAB+C process from the AE Solar Permitting Manual and the AE Solar Inspections page (page footer: 'Date last reviewed or modified: 11/21/2025'). Deducted because the county's 'B' permit notification channel is stated in ordinance text from 2019, not in a current process page.
utility department page + county ordinance checked 2026-08-28 https://austinenergy.com/green-power/solar-solutions/solar-inspections
Q50 How much notice is required? Core Booking & scheduling
Austin Energy: no fixed notice period is published; after a request is submitted the AE Solar Inspections team schedules it and the contractor receives an email with the date/time 'usually within 3 business days'. Travis County (floodplain 'B' permits only): 'The permittee shall notify the Floodplain Administrator 48 hours before construction is ready for the above inspection.'
Why the confidence is not higherThe '3 business days' figure is AE's own wording and is explicitly a typical, not a commitment. The 48-hour figure is verbatim ordinance text from Code 464.069 but applies to floodplain 'B' permit inspections, not to a PV system.
utility permitting manual + county ordinance checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Green-Power/Solar/AustinEnergy_SolarPermittingManual.pdf
Q51 Are same-day or AM/PM windows offered? Booking & scheduling
No same-day inspections. Austin Energy warns explicitly: 'Although the page may state that the inspection is scheduled for the same day, this is FALSE. The inspection is not yet scheduled and will not be performed on the same day.' Contractors supply their availability and contact details with the request; no AM/PM window system is published.
Why the confidence is not higherVerbatim from the AE Solar Permitting Manual, 'Scheduling Inspections'. The absence of AM/PM windows is an absence across the manual and the solar inspections page rather than a stated policy.
utility permitting manual checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Green-Power/Solar/AustinEnergy_SolarPermittingManual.pdf
Q52 Does this AHJ perform its own final solar inspection? Core Who inspects
No / Delegated. Travis County does NOT perform a final solar inspection. Its own Solar Permit page has an 8-step process with no inspection step at all — it ends at 'Receive the Permit' and 'Post the permit somewhere visible from the public right of way'. Contrast the county's Single-Family Home, Addition and Remodel permit pages, which all state inspections 'must be performed by a licensed 3rd party inspector'. The DG inspection is performed by the utility: in Austin Energy territory, by the AE Solar Inspections team.
Why the confidence is not higherBuilt from a direct comparison of four of the county's own permit pages plus Code 480.005/480.006. Deducted because 'the solar page has no inspection step' is an absence — I could not find a county document that says in terms 'the County does not inspect solar'. A floodplain 'B' permit within a special flood hazard area can still draw a county foundation and mechanical/electrical inspection under 464.069, which is the one route by which a county inspector could appear on a solar job.

Q53 If delegated, to whom? Core Who inspects
Two delegations. (1) Electrical / DG inspection → the serving utility; in Austin Energy territory, Austin Energy Solar Inspections (solarinspections@austinenergy.com, 512-482-5346). (2) Building-code inspection where Ch. 480 applies at all (new SFH/duplex or >50% addition) → a third party contracted by the builder: a licensed engineer, registered architect, TREC-licensed professional inspector, a municipally-employed TSBPE-licensed plumbing inspector, a building inspector employed by a political subdivision, or an ICC-certified residential combination inspector.
Why the confidence is not higherThe six inspector categories are verbatim from Code 480.006. The AE delegation is from AE's own inspections page: 'all solar energy systems that are installed in Austin Energy service area must pass a final solar inspection before they can be turned on'.

Q54 Which inspections are required, and in what order? Core Stages & sequence
Austin Energy sequence: (1) optional pre-construction meeting with an AE DG inspector (mandatory for commercial); (2) Rough inspection (301) where wiring will be covered before completion, and/or Temporary Power (304) and pre-wire final inspections where applicable; (3) all other related permits (Repair / Upgrade EPs) must reach 'Final' status; (4) Final solar inspection (305); (5) AE Distribution Metering Operations reviews and approves the as-built revenue and solar meter installation and installs the solar meter(s); (6) permit moves to 'Final' = Permission to Operate. Where a CT meter is required, the CT meter inspection sits after a passed 304 Temporary and before the final 305 is requested. Travis County adds no inspection stages for rooftop PV.
Why the confidence is not higherReconstructed from the AE Solar Permitting Manual ('Scheduling Inspections', 'Permission to Operate') and the AE Solar Inspections page, which both name the numbered inspection types. Deducted because inspection-type numbering appears in AE's page and DIG rather than in a single sequence diagram.

Yes, conditionally. Austin Energy: 'If any parts of the system (e.g., wiring) will be covered up before the installation is complete, request a Rough Inspection to have them reviewed first.' A separate Pre-Wire Final inspection applies where wiring is installed for a future solar installation (typically new construction), and a Pre-wire ONLY Auxiliary Power EP exists for that case.

Q56 Does the inspector verify labels and listings? Core What is checked
Yes. Austin Energy's published DG/DER Inspection Checklist verifies both explicitly: 'All equipment has permanent labels'; 'All installed equipment is UL listed'; 'All meters, disconnects, and directory placard are grouped' (with 'Any equipment that cannot be grouped has a variance approval'); 'Conduit with DC PV output conductors is labeled every 10 feet, per NEC 690.31.D.2'; 'Meter socket is approved by Austin Energy for use'; and inverter certification/CEC listing checks.
Why the confidence is not higherAll quoted verbatim from AE DIG rev. 14.0 Appendix C. This is a published checklist, not inferred practice.

No at county level — Travis County publishes no inspection checklist for solar (and performs no such inspection).
Why the confidence is not higherThe checklist was extracted directly from the PDF with pdftotext -layout, not summarised. County absence follows from the county performing no PV inspection.

Q58 What must be on site at inspection? Core Documents on site
County: the issued development permit must be posted somewhere visible from the public right of way on the work site before the project begins. Utility (Austin Energy): the Auxiliary Power EP must be in Active status with the permit address matching the installation address; all Upgrade or Repair EPs for the same property closed; the installation consistent with the electrical design drawings; and contractor contact details supplied for the day of inspection. Where equipment is not grouped, the approved meter variance must be in hand.
Why the confidence is not higherCounty half verbatim from step 8 of the Solar Permit page; utility half from AE DIG Appendix C 'General' and the manual's inspection-request fields. Deducted because neither source frames this as a 'documents on site' list — it is assembled from what each requires to be true at inspection.

Q59 Is there a re-inspection fee? Corrections & re-inspection
Travis County: $200 per inspection after the initial free inspection (Inspections section of the FY2026 fee schedule); a separate $249 per corrective action report issuance & follow-up inspection applies to Permanent Water Quality Control non-compliance. Austin Energy: a re-review fee is charged for a 3rd DG Plan Review after two failures — the amount is not published in the manual.
Why the confidence is not higherBoth county figures read directly from the fee schedule, but neither is solar-specific and the county does not inspect rooftop PV, so the $200 would only bite via a floodplain 'B' permit. The AE re-review fee amount is genuinely unpublished.

Q61 What is issued on pass? Core Final sign-off & PTO
The operative sign-off is the utility's: the Auxiliary Power EP moves to 'Final' status once AE Distribution Metering Operations has approved the as-built revenue and solar meter installation and set the solar meter — 'At this point, the project is closed, and the customer has Permission to Operate (PTO)', confirmed by a PTO email. Travis County issues no final or CO for rooftop PV; a Certificate of Occupancy exists only for floodplain 'B' permit construction, and is literally 'a copy of the B permit with inspections noted or certification attached and bearing the words Certificates of Occupancy followed by the dated signature of the Floodplain Administrator'.
Why the confidence is not higherAE half verbatim from the Solar Permitting Manual 'Permission to Operate'; county half verbatim from Code 464.069. Deducted because the county's development permit closeout for a non-floodplain solar job is not described anywhere I could find.
utility permitting manual + county ordinance checked 2026-08-28 https://austinenergy.com/-/media/Project/Websites/AustinEnergy/Green-Power/Solar/AustinEnergy_SolarPermittingManual.pdf
Q62 Who notifies the utility for PTO? Core Final sign-off & PTO
Utility pulls. Nobody notifies Austin Energy — AE is already inside the process. AE Distribution Metering Operations reviews and approves the final as-built meter installation, installs the solar meter(s), updates the meter details on the permit and moves it to 'Final'; contractors and customers are then notified by email that PTO is granted. There is no AHJ-to-utility handoff because Travis County is not in the electrical chain at all.
Why the confidence is not higherVerbatim from the AE Solar Permitting Manual, which also lists 'Permission to Operate; PTO is granted' among the automated notifications and reproduces an example PTO email. Deducted because this holds only in AE territory; the co-op PTO route is unconfirmed (see Q22).

Jurisdiction & key facts
The standing 62-question set, answered for Travis County against this authority’s own published documents. Every answer carries the confidence it was recorded at and the document it came from. Where nothing is published we say so and show where we looked — a blank here is a finding, not a gap.
Jurisdiction unconfirmed 90% confidence
- Holds
- Land-development / floodplain permitting only. Travis County DOES require and issue a permit for residential rooftop PV in the unincorporated county — a 'Development (Residential)' permit from TNR Development Services — but it is NOT a building-code AHJ and NOT an electrical AHJ for rooftop PV, and it performs no building or electrical inspection of one- and two-family dwellings.
- Delegated to
- Building-code inspection (where it applies at all) is delegated by ordinance to third-party licensed inspectors — a licensed engineer, registered architect, TREC-licensed professional inspector, a municipal plumbing inspector, a building inspector employed by a political subdivision, or an ICC-certified residential combination inspector (Travis County Code 480.006). The electrical/DG inspection is performed by the serving utility: in Austin Energy territory, by Austin Energy Solar Inspections.
- Overridden by
- Texas Local Government Code Chapter 233 — the county's own code cites Subchapter C (fire code in unincorporated area) as the authority for Ch. 201 and Sec. 233.157 as the enforcement route for Ch. 480. Texas counties have no general building-permit or zoning power, no adopted NEC here, and Ch. 480 expressly yields to a municipality's ETJ building code where one has been adopted (480.004(b)). Where the City of Austin's ETJ covers the parcel, the municipal building code controls and Ch. 480 has no effect.
- Why not higher
- The county publishes its own dedicated 'Solar Permit' page under Single-Family Development Permits, stating rooftop solar is applied for as a 'Development (Residential)' application — so the county is unambiguously A permitting authority. But three of its own documents establish it is not the building/electrical AHJ: (1) Code Ch. 480 applies only to 'new residential construction' — a new SFH/duplex on a vacant lot, or an addition increasing square footage or value by >50% — which a rooftop array is not, and even then the COUNTY does not inspect, the builder hires a third-party inspector; (2) the current Fire Code (Ch. 201, 2021 IFC as of 1 Jan 2026) applies only to commercial establishments, public buildings and multifamily >3 units, so a single-family dwelling is not a 'Building' under it; (3) a full-text search of the Travis County Code returns ZERO hits for 'National Electrical Code', 'rapid shutdown', 'one-line', 'photovoltaic' and 'windstorm', with positive controls passing ('electrical' 16, 'building' 163, 'fire code' 35) and the fabricated control 'zzqqx' returning 0. Deducted 10 because the exact scope of what TNR reviews on a rooftop-PV application is inferred from the solar page's document list (site plan, ESC plan, restoration plan, floodplain, easements) rather than from a solar-specific ordinance section — no such section exists.

All other AE placards are specified by reference to the NEC rather than by wording.

Where they go 90%
Grouped at the service equipment. Austin Energy requires the following to be grouped: Directory Plaque, Main Service Disconnect, Billing Meter, PV Meter, Main PV AC Disconnect, and ESS Main Disconnect. Where grouping is not practical, a meter variance must be approved BEFORE installation (submit to AEAdvancedMeteringEngineering@austinenergy.com, including 'a proposed placard language describing the alternative location'). Exceptions: an ESS directory plaque must be installed by the ESS equipment if that equipment is not grouped, not to exceed 20 feet without an approved variance; for utility-side interconnections, plaques go at the point of interconnection, at each disconnecting means, and on the roof by the array; DC PV conduit labels go every 10 feet along the run.
What the utility wants on top 90%
Yes — and in this jurisdiction the utility's placards are the ONLY placards in play, because Travis County specifies none. See Q38 for the full Austin Energy list, including two AE-specific labels that have no NEC equivalent (the PV aggregate panel label and the AE-supplied battery-recycling QR-code label on the ESS).
