Orange County

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? Yes — Orange County Division of Building Safety is the AHJ, but ONLY for unincorporated Orange County. Its own checklist tells applicants to first check the Property Appraiser site (ocpafl.org) for 'Un-Incorporated' before using this department. 92% · County submittal checklist, revised 11/21/23
• What does this authority permit itself, and what does it delegate? Both — for unincorporated-county rooftop residential PV the County issues one combined 'S' (Sun) permit covering building + electrical review and inspection. For ground-mount and commercial PV it issues a Building permit first, then a separate Electrical sub-permit. It does not delegate solar permitting within its own unincorporated jurisdiction, but the incorporated cities inside the county boundary (Orlando, Winter Park, Apopka, Ocoee, Winter Garden, Maitland, Belle Isle, Edgewood, Eatonville, Windermere, Bay Lake, Lake Buena Vista) are separate AHJs with their own departments. 85% · County submittal checklist
• Is a permit required for a residential rooftop PV system? Yes, a permit is required for residential rooftop PV in unincorporated Orange County. 90% · County submittal checklist
• Is there a separate electrical permit, or is it combined? Either, depending on mount type. Residential ROOFTOP PV: Combined — a single 'S' (Sun) permit covers both building and electrical review/inspection. Ground-mount and commercial PV: Separate — a Building permit must be approved first, then a separate Electrical sub-permit is required for the interconnection wiring. 88% · County submittal checklist
• Is a HOA or architectural approval required first? No — the County's own submittal checklist lists the complete required package (structural + electrical plan sets) and does not include an HOA or architectural-approval letter anywhere in it. This is reinforced by Florida Statute 163.04 (the state Solar Rights Act), which bars deed restrictions and HOA governing documents from prohibiting solar installations outright (though HOAs may impose limited placement conditions that don't impair performance). 65% · County submittal checklist (absence) + FS 163.04 (state preemption)
• Is a wind or windstorm certification required? No separate 'windstorm certification' program — Orange County is NOT a High-Velocity Hurricane Zone (HVHZ is Miami-Dade/Broward only) and has no TDI-style wind-certificate requirement. Wind resistance is instead folded into the ordinary structural-stamp submittal: the checklist requires the engineer to state 'Wind speed (Search ATC Wind Speed by Location)... Exposure, Risk Category, and Minimum design loads' on the stamped structural plan. 70% · County submittal checklist
• Is there a system-size cap on residential generation? No county-imposed kW/system-size cap was found in the County's own permitting documents. A practical ceiling instead comes from utility net-metering tariffs — e.g. OUC's TruNet Solar residential net-metering program caps eligibility at 10 kW — but that is a UTILITY program limit, not a County zoning or building cap, and does not stop a larger system from being installed and permitted. 55% · County submittal checklist (absence) + OUC TruNet Solar program page (utility cap)

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 OR licensed solar contractor. The checklist names only two contractor classes as eligible to obtain the permit: Electrical Contractors (EC, ER) and Solar Contractors (CVC) — with the note that if a Solar Contractor (CVC) pulls the Sun permit, a separate Electrical Contractor is still required to make the utility interconnection. 85% · County submittal checklist
• Must the contractor be registered with this authority before applying? Yes — contractors must be registered/verified with Orange County (via the county's ContractorLicensing function, which records proof of general liability insurance and workers' compensation coverage) before a permit will be issued in their name. 60% · Building Safety department page + contractor licensing contact
• Is a homeowner permitted to self-install and self-permit? Ambiguous / likely limited. The County's general Building Safety guidance allows owner-builder permits for owner-occupied property ('Property owners may obtain owner/builder permits for owner-occupied properties'), but the solar-specific checklist names only Electrical Contractors and Solar Contractors as who 'can obtain the permit' for Sun/PV work and does not mention a homeowner route for solar specifically. 45% · County submittal checklist vs. Building Safety department page

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? Rooftop residential ('S' Sun permit, no plan review at OTC issuance): permit application via Fast Track plus (a) structural details signed/sealed by a Florida engineer showing panel attachment, noting code edition/section, wind speed, exposure/risk category, design loads, roof height/slope/covering, roof plan with module/rail/fastener dimensions and attachment method, and flashing/waterproofing detail; and (b) electrical plans certified by FSEC (or, in lieu of FSEC, by a FL-licensed engineer) showing system description/operation, site plan of new + existing equipment, riser diagram, electrical schematic (array config, wire sizes/types, junction boxes, disconnects, OCP, grounding, required signs, AC connection), electrical calculations (ampacity, derating, conduit fill, voltage drop, output specs), and spec sheets/installation manuals for all major components. Ground-mount/commercial: same package plus a full Building-permit submittal. 90% · County submittal checklist
• How many copies, and in what format? Electronic only — 'All permitting in Orange County is done electronically through our Fast Track website'; the checklist gives no separate hard-copy count, and payment/plan submission both happen through the portal. 70% · County submittal checklist
• Is a site plan required, and what must it show? Yes — the electrical plan set must include 'Site plan showing locations of all new equipment and existing service equipment,' and the structural plan set must show roof height/slope/covering and module/rail layout, which functions as the site/roof plan for a rooftop system. 80% · County submittal checklist
• Is a one-line / three-line diagram required? Yes — 'Riser diagram showing how the new PV system ties into existing service' and a full 'Electrical schematic diagram' (array configuration, wire sizes/types, junction boxes, disconnects, OCP, grounding, required signs, AC connection) are both required. 90% · County submittal checklist
• Are string and conductor calculations required? Yes — 'Electrical calculations' are explicitly required, covering wire ampacity, temperature derating, conduit fill/derating, voltage drop for DC and AC conductors, ambient-temperature effects on array output, and disconnect/OCP/input-output current-voltage-power sizing for every major component. 90% · County submittal checklist
• Is a structural PE stamp required, and at what threshold? Yes, and at NO stated minimum threshold for rooftop — a structural PE (or FL-licensed architect) stamp is required on every rooftop installation: 'Details signed and sealed by a Florida Engineer showing how the panels are attached to the roof,' compliant with FBC-Residential 8th Ed. §324. For ground-mount/commercial work the same stamped-structural-calculation requirement applies via the full Building-permit process. 85% · County submittal checklist
• Is an electrical PE stamp required, and at what threshold? Not required as a default — electrical plans may instead be 'certified by FSEC (Florida Solar Energy Center)... or in lieu of FSEC, certified by a Florida licensed engineer.' A PE stamp is therefore only needed if the installer does not route the plans through FSEC certification. 85% · County submittal checklist

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? OC Fast Track — https://fasttrack.ocfl.net/OnlineServices/ — the County's single electronic permitting portal for application, plan submittal, payment, inspection scheduling and status. 95% · Portal landing page
• Can the whole application be completed online? Yes — 'All permitting in Orange County is done electronically through our Fast Track website,' including online payment by credit card or escrow account; note Orange County does NOT appear in the national SolarAPP+ jurisdiction directory (checked directly), so this is the County's own bespoke electronic system, not SolarAPP+ automated issuance. 80% · County submittal checklist; SolarAPP+ directory checked as a negative control
• What does a residential solar permit cost? No dedicated 'solar' fee line exists in the Fee Directory; the checklist states the fee 'will be based on the total cost for all materials, labor, and fixtures installed,' which matches the Electrical-Permit-Fees valuation schedule for work not requiring a change of electrical service: $38 minimum for the first $1,000 of valuation, plus $5 for each additional $1,000 or fraction. Example: a $25,000 residential PV job ≈ $38 + 24×$5 = $158, before any Business-Tax/records/card-processing add-ons. 55% · FY2025-2026 Fee Directory (eff. July 2025) + County submittal checklist
• How is the fee calculated? Valuation — 'based on total cost for all materials, labor, and fixtures installed,' matching the Electrical Permit Fees valuation-based schedule ($X per $1,000 of cost), not a flat rate, per-kW, per-panel, or tiered rate. 60% · FY2025-2026 Fee Directory
• Is there a separate plan-check fee? No — the Fee Directory's 'Plan Submittal Fee' table lists a dollar amount only for '(2) All Other Building Occupancies' (a sliding scale from $32 to $849+ by valuation); the '(1) One and Two Family Dwellings' line carries NO dollar amount at all, i.e. residential plan submittal/plan-check is not separately charged. 70% · FY2025-2026 Fee Directory

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.

• What is the stated plan-review turnaround? The County's own Solar and Clean Energy page states solar permits are 'typically approved within 24 hours' in unincorporated areas for the over-the-counter rooftop path. Separately, Florida Statute 553.791(7)(a) (as amended by 2025 HB 683 / Ch. 2025-140) sets a statutory outer bound of 5 business days for single-trade plans review of residential solar/ESS permits when a private provider affidavit is used, with automatic approval the next business day if the County misses that window. 65% · County department page ('Solar and Clean Energy') + FS 553.791(7)(a)
• How long is an issued permit valid before it expires? 180 days from issuance or the date of the last passed inspection before the permit expires; one-time 90-day administrative extension available (fee $32, per the Fee Directory's 'Extension Request'). 85% · Building Safety department page + Fee Directory
• Which utility handles interconnection here? Split by parcel — unincorporated Orange County is served by TWO different electric utilities depending on exactly where the parcel sits: Duke Energy Florida (investor-owned, serves most of the county) and Orlando Utilities Commission / OUC (a municipally-owned utility that also serves 'portions of adjacent unincorporated areas of Orange County' beyond Orlando's city limits, per OUC's own service description). There is no single county-wide utility; the installer must confirm from the customer's own utility bill or the utility's territory map, not from a ZIP-code lookup tool. 50% · Utility's own service-area description (OUC) + Duke Energy Florida territory map
• Where does the utility sit in the sequence? After permit issuance, before/at final inspection — the installer submits a separate interconnection application directly to whichever utility serves the parcel (Duke Energy Florida or OUC); Permission-to-Operate (PTO) is issued by the utility only after the County's Electrical Final inspection has passed and documentation is forwarded, so utility PTO sits in parallel-but-downstream of the County's own final sign-off, not as a precondition to pulling the permit. 55% · Utility interconnection process description (Duke Energy Florida)

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? 2020 NEC (National Electrical Code). 95% · County submittal checklist
• Which building code edition is in force? Florida Building Code, Residential, 2023, 8th Edition (for one- and two-family dwellings). 95% · County submittal checklist
• Which fire code edition is in force? Florida Fire Prevention Code, 8th Edition (2023), effective 31 Dec 2023 — the statewide code the State Fire Marshal readopts every three years under F.S. 633.202; Orange County Fire Rescue's Office of the Fire Marshal enforces this code (and Florida Administrative Code 69A-60) but I did not find a County ordinance naming the edition explicitly, only OCFR's general statement that it enforces the Florida Fire Prevention Code and related state rules. 55% · State Fire Marshal FFPC adoption page + OCFR standard #6005 (indirect)
• Are there local amendments to any of the above? Yes, in general — the Building Safety page states the department enforces 'the Florida Building Code, the National Electrical Code and Orange County Construction Regulations' (i.e., a body of local amendments/regulations exists, codified at Code of Ordinances Ch. 9), but no solar-specific local amendment to FBC §324 or NEC 690/705 was located in the documents reviewed. 50% · Building Safety department page
• What is the installation judged against? The Florida Building Code, Residential, 8th Edition (2023) §324, plus the 2020 NEC — the checklist states plainly: 'All roof-top installations shall comply with section 324 of the 2023 Florida Building Code, Residential, 8th Edition,' with electrical work judged against the 2020 NEC and FSEC/PE-certified electrical plans. 90% · County submittal checklist

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? Florida Residential Code §R324.6 (statewide, carried into the FBC-R 8th Ed. 2023): not fewer than 2 pathways per building (≥36 in. wide, lowest edge to ridge, at least one on the street/driveway side, plus one per PV-covered roof plane); ridge setback of 18 in. on both sides where the array covers ≤33% of plan-view roof area (≤66% if the dwelling has a fire sprinkler system), rising to 36 in. above those thresholds; panels may not be placed below an emergency escape/rescue window, and a 36 in. pathway must reach that window. Exempted: detached non-habitable structures, roofs ≤2:12 slope, and cases where the code official determines rooftop fire operations won't be used. 70% · ICC Significant Changes commentary on FBC-Residential §R324.6 (reproduced by Leon County FL)

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 — rapid shutdown is required under NEC 2020 §690.12, the electrical code the County enforces (checklist: '2020 National Electrical Code'). NEC 2020 690.12 requires controlled conductors outside the array boundary to be limited within 30 seconds of initiation, and (for one/two-family dwellings) an initiation device that is outside and readily accessible. 75% · County submittal checklist (NEC edition) + NEC 2020 §690.12 (national code text)

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? No Orange-County-specific placard beyond what NEC 2020 itself requires. The checklist's electrical-schematic bullet lists 'required signs' as one of the items the diagram must show, without naming or specifying any placard of the County's own — so the placards required are exactly the NEC 2020 set: PV system/service disconnect labels (690.13), photovoltaic power-source conduit/raceway marking (690.31/690.53), rapid-shutdown label (690.56(C)), and (where multiple sources exist) the NEC 705.10 facility/directory placard. 55% · County submittal checklist (absence of county-specific spec) + NEC 2020 (national baseline)
• Does the authority specify placard wording of its own? No — the County does not publish its own placard wording. The checklist requires the electrical schematic to show 'required signs' but does not specify text, so wording defaults entirely to NEC 2020 (e.g., the mandatory 690.56(C) rapid-shutdown wording 'SOLAR PV SYSTEM EQUIPPED WITH RAPID SHUTDOWN'). 60% · County submittal checklist
• Does it specify letter height, colour or material? No — the County specifies no letter height, colour, or material of its own for PV placards. Those parameters come from NEC 2020 itself (e.g., §690.56(C): red background, white lettering, minimum 3/8 in. uppercase letters, UL 969-rated weatherproof material) rather than from any Orange County ordinance or checklist. 55% · County submittal checklist (absence) + NEC 2020 §690.56(C) (national baseline)
• Is a site plan / facility map placard required, and what must it show? Governed by NEC 705.10 (facility/service-disconnect directory placard) rather than by any Orange-County-specific form. Where a building has multiple power sources (utility service + PV), 705.10 requires a permanent plaque/directory at each service-equipment location showing the location of all on-site power sources. No County checklist or ordinance adds anything beyond this national requirement. 50% · County submittal checklist (absence) + NEC 2020 §705.10 (national baseline)
• Where must the labels be placed? At the points NEC 2020 requires: PV/service disconnect labels at the disconnecting means itself; photovoltaic-power-source conduit/raceway marking at intervals along exposed runs and at turns/penetrations (NEC 690.31/690.53); the rapid-shutdown label at (or immediately adjacent to) the initiation device and at the service disconnect; and the 705.10 multi-source directory placard at the main service equipment. The County's own checklist does not add or relocate any of these — it only requires the electrical schematic to show 'required signs' without further placement detail. 50% · County submittal checklist (absence) + NEC 2020 (national baseline)

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? Not established from an Orange-County-specific document. The general pattern for Duke Energy Florida DG interconnections (one of the two utilities serving the unincorporated county) is an externally accessible, lockable, manual AC load-break disconnect switch located in close proximity to the meter — but I could not open Duke's own interconnection-requirements PDF to quote it directly, and OUC's equivalent requirement was not located at all, so this is a low-confidence, unverified secondary read rather than a sourced answer. 40% · Duke Energy Florida generator-interconnection document (search-summary only, not independently verified)
• Must equipment be on a specific approved list? No county-specific approved-equipment list — the requirement is the standard national listing/labeling standard: PV modules listed to UL 1703 or UL 61730-1/-2, and inverters listed to UL 1741 (per FBC-R §324.3.1, which the County's checklist incorporates by requiring 'Specification sheets and installation manuals for all manufactured components'). 60% · County submittal checklist + FBC-R §324.3.1 (state code)
• Is a ground mount treated as a structure? Yes — ground-mount PV is treated as a structure requiring a full Building permit ('All ground mount systems shall begin as a Building permit'), distinct from the lighter-weight rooftop-only 'S' Sun permit path. 85% · County submittal checklist
• Is a specific mounting system or attachment spacing required? No fixed county-mandated mounting system or attachment spacing — the requirement is performance-based: the checklist requires 'Support rail and module dimensions, weights, materials, and methods of attachment' and 'Fastener type, material, diameter, length, and spacing' to be shown on PE-stamped structural plans for EACH project (may be supplemented by manufacturer cut sheets), rather than specifying a single approved system or a fixed spacing table itself. 70% · County submittal checklist

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 (primary) — OC Fast Track, including a 'Get In Line' same-day queue feature — with phone as the published alternative: '407-836-5550.' 85% · County submittal checklist
• How much notice is required? Approximately 24 hours — Fast Track's scheduled-appointment flow only offers date/time slots at least 24 hours in the future ('FlexAppointment... at least 24 hours in the future'). 60% · Fast Track portal scheduling tool
• Are same-day or AM/PM windows offered? A same-day walk-in/queue option exists via Fast Track's 'Get In Line' feature (subject to a same-day cutoff — walk-ins not accepted after 4:45 PM Mon-Fri), in addition to the ≥24-hour-ahead scheduled FlexAppointment slots; no specific AM/PM inspection window system (e.g., a 2-hour arrival window) was found published. 50% · Fast Track portal scheduling tool

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? Yes — Orange County performs its own final solar inspection. The checklist lists only County-performed inspections ('Electrical Rough and Electrical Final') with no third-party/private-provider substitution mentioned, though FS 553.791 (state law) independently gives applicants the OPTION to use a private provider for single-trade solar inspections instead of the County inspector. 75% · County submittal checklist + FS 553.791 (state private-provider option)
• If delegated, to whom? Not delegated by default — Orange County Division of Building Safety inspectors perform the Electrical Rough and Electrical Final inspections directly. Under FS 553.791, an applicant MAY instead engage a state-licensed private provider (engineer, architect, or certified building code inspector) to perform plan review and/or inspection in the County's place, but that is an applicant election, not a standing County delegation. 70% · County submittal checklist + FS 553.791

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? Electrical Rough, then Electrical Final — the only two inspections the checklist names for rooftop PV, in that order (per the Inspection Record Card's numbered inspection codes). Ground-mount/commercial jobs additionally go through the standard Building-permit inspection sequence (e.g., footing/foundation) ahead of the electrical inspections, since they are issued as full Building permits. 80% · County submittal checklist
• Is a rough-in or mid-roof inspection required? Yes — 'Electrical Rough' is a required inspection distinct from and preceding 'Electrical Final' for rooftop PV. 80% · County submittal checklist

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.

• What must be on site at inspection? Inferred from general Fast Track practice rather than a solar-specific list: the physical/printed Inspection Record Card (with inspection code numbers on the back) must be available on site, along with the approved plan set and any product spec sheets/installation manuals submitted with the permit (per the checklist's 'may be supplemented by product cut sheets' language, implying those sheets travel with the job). 50% · County submittal checklist (inference)
• Does the inspector verify labels and listings? Not stated explicitly by the County, but inferred Yes — verifying required labels and equipment listings (module/inverter UL listings, disconnect and rapid-shutdown labels) is a standard, code-mandated part of an NEC 2020 'Electrical Final' inspection, and the checklist itself requires 'required signs' to be shown on the submitted schematic and 'Specification sheets and installation manuals for all manufactured components' to be provided — both of which an inspector would check against at final. 50% · County submittal checklist (inference, not a direct statement)

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? Passing the Electrical Final closes/finalizes the permit. Because a rooftop PV retrofit does not change the building's occupancy classification, the closeout document is a Certificate of Completion (or simply a 'finaled'/closed permit status in Fast Track) rather than a Certificate of Occupancy; no county document mentions a physical 'green tag' or letter specific to solar. 45% · Inference — no direct County statement found
• Who notifies the utility for PTO? Installer — in practice the solar company/installer submits the separate interconnection application to whichever utility (Duke Energy Florida or OUC) serves the parcel once the system has passed the County's final inspection, and PTO is granted by the utility, not requested by the County. 55% · Utility interconnection process description (Duke Energy Florida / OUC), not a County document
• Is there a re-inspection fee? $38.00 flat re-inspection fee. 80% · FY2025-2026 Fee Directory
• How are corrections issued and cleared? Not documented for solar specifically. General Fast Track practice (inferred): a failed inspection generates comments/corrections visible in the portal; the applicant/contractor corrects the work and reschedules a re-inspection through the same Fast Track booking channel used for the original inspection, paying the $38 re-inspection fee where applicable. 40% · Inference from Fee Directory (re-inspection fee) + Fast Track portal function, not a direct process document
