Walton 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 — Walton County Building Department is the AHJ for residential solar for the entire county, including inside DeFuniak Springs and Freeport city limits 90% · city department page
• What does this authority permit itself, and what does it delegate? Both — Walton County Building Department issues and inspects Building and Electrical permits county-wide (including DeFuniak Springs and Freeport). Planning/zoning site-plan review is a separate, city-level prerequisite inside DeFuniak Springs and Freeport; commercial projects inside Freeport and Paxton additionally need city approval 88% · County inspection checklist
• Is a permit required for a residential rooftop PV system? Yes, a permit is required 90% · adopting ordinance (2025)
• Is there a separate electrical permit, or is it combined? Either — the County's Standalone Permit Application covers Electrical alone (service panel/service change categories, no PV-specific line), while a roof-mount PV job with structural racking work would go through the Building Permit Application instead. There is no dedicated combined 'solar' permit type 60% · County permit application form
• Is a wind or windstorm certification required? Yes. Every building permit application requires an Owner Wind Certification or engineer/architect wind-load certification stating a specific design wind velocity per Florida Building Code Ch. 16; inside the Coastal Building Zone, certification of a 140 MPH (or engineered-interpolated) design by a Florida-registered architect or engineer is mandatory regardless of project size 85% · County ordinance + County form
• Is there a system-size cap on residential generation? The County itself does not cap residential system size for permitting. The operative cap is at utility level: CHELCO's net-metering rate (RS-N/RS-NTOU) is available only to residential customers with 'installed electric generation of less than 25 kilowatts (kW) alternating current'; FPL's Tier 1 (no-application-fee, streamlined) path caps at 10 kW AC gross power rating, not exceeding 90% of the customer's distribution service rating or 115% of the prior 12 months' kWh usage 78% · utility tariff

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? Either — a DBPR-certified/registered electrical or solar contractor registered with the County, or the property owner as owner-builder 65% · County department page
• Must the contractor be registered with this authority before applying? Yes — Certified/Registered contractors must register their state DBPR license with Walton County before working in the county 90% · County department page
• Is a homeowner permitted to self-install and self-permit? Yes — an owner-builder route exists (Construction by Owner Disclosure Statement, Electrical Disclosure Statement forms are published), but no solar-specific statement confirms it applies to PV specifically 60% · County permit forms index

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? For a residential PV project (treated as an 'other buildings' addition/alteration under the general Building Permit Checklist): (1) Building Permit Application, (2) parcel number, (3) proof of ownership (recorded deed), (4) Planning-approved site plan with review sheet/letter (from County or the applicable city planning department), (5) plans — signed & sealed if outside the Coastal Building Zone, or stamped & sealed by an FL architect/engineer if inside it, with the Wind Load Statement attached, (6) Product Specification Approval Sheet (from floridabuilding.org) for the racking/module product approval, (7) Energy Form if adding heating/cooling load (not applicable to PV itself). No solar-specific checklist exists — this is the general checklist, read in full, with no solar carve-out 65% · County checklist (revised 07/21/26)
• How many copies, and in what format? For non-coastal projects: one hard copy, signed & sealed, plus one electronic copy on CD in PDF format. For projects in the Coastal Building Zone: one hard copy stamped & sealed by a Florida-registered architect or engineer, plus one electronic copy on CD in PDF. A $29.00 plan review deposit is collected at submittal (cash, check, or credit card; no personal checks from couriers) 80% · County checklist
• Is a site plan required, and what must it show? Yes — a Planning-Department-approved site plan with review sheet and/or letter is required; the checklist does not itemize what the site plan must show beyond that approval, referring applicants to County Planning (850-267-1955) or the applicable city Planning contact 60% · County checklist
• Is a one-line / three-line diagram required? Not required by the County's own checklist for a roof-mount retrofit; the utility (CHELCO, in CHELCO territory) requires one for interconnection: 'electrical one-line diagram and specification sheets for inverter, renewable energy source and other installed equipment, such as PV panels' 70% · utility interconnection instructions (2026)
• Is a structural PE stamp required, and at what threshold? Any construction/addition over 100 sq ft (non-coastal) requires plans signed & sealed by an architect/engineer; anything within the Coastal Building Zone requires certification by a Florida-registered architect or engineer regardless of size, stating the structure is 'designed to withstand a wind velocity of 140 MPH (unless engineering interpolation provided or in a V-Zone)' 80% · County ordinance (Coastal Building Zone, 2007-53) + Building Permit 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? Tyler Technologies EnerGov 'SelfService' portal — waltoncountyfl-energovweb.tylerhost.net — used for building permitting, and also referenced as 'Civic Access' on the County's own inspection checklist; Planning applications also route through the same EnerGov tenant as of 1 Nov 2023 85% · County department page
• What does a residential solar permit cost? $0 currently — Walton County's building permit fees (including electrical) are abated to $0.00 from 1 Oct 2025 through 30 Sep 2026 under Resolution 2025-58, continued by Resolution 2025-70, because the Building Department fund balance exceeded the statutory cap of F.S. 553.80. Absent the abatement, the underlying fee would be assessed either as a valuation-based building permit fee (Attachment A table, using contractor's contract cost, if filed as a Building permit) or under the Residential Electrical Fee Schedule (Attachment D — no PV-specific line; nearest categories are Main-Service-Size fees $25–$75, or Miscellaneous Wiring at $2.00 per circuit) if filed as a standalone electrical permit. Minimum permit fee is $35.00 outside the abatement period 82% · fee resolution (adopted Sept 2025, OCR'd — scanned/no text layer)
• How is the fee calculated? Valuation-based if filed as a Building permit (contractor's contract cost against the Attachment A/valuation table); per-circuit ($2.00/circuit, Miscellaneous Wiring) or by Main Service Size if filed as a standalone Electrical permit. All are currently $0 under the active fee abatement (see q15) 60% · fee resolution (OCR'd)
• Is there a separate plan-check fee? Yes, normally — plan review fee is 10% of the calculated permit fee, $25 minimum, collected at submittal and non-refundable. Currently $0 under the same fee abatement as q15 (Resolution 2025-70/2025-58 abate Sec. 6-30(a) through (j), which includes the plan-review fee at (b)) 85% · fee resolution (OCR'd)

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.

• Which utility handles interconnection here? Split by parcel. FPL (the legacy Gulf Power territory, now operating under FPL's tariff post-merger) serves 'City of DeFuniak Springs', 'Paxton' and 'Unincorporated - Walton' per FPL's own PSC-filed tariff Section 7 'Communities Served' (with a Walton-specific footnote grouping it with Bay/Escambia/Holmes/Jackson/Okaloosa/Santa Rosa/Washington as legacy Gulf Power counties). CHELCO (Choctawhatchee Electric Cooperative), headquartered in DeFuniak Springs, separately serves other parts of unincorporated Walton and, by elimination, likely Freeport (Freeport does not appear on FPL's Walton list). There is no single utility for 'this address' without a specific parcel 80% · PSC-filed electric tariff, Section 7 (Communities Served)
• Where does the utility sit in the sequence? After permit (both utilities). CHELCO's Tier 1 instructions state explicitly: 'Once your system has been inspected by the county building department, submit the following...' including 'proof of county inspection' — i.e. County final inspection is a precondition of the CHELCO application itself. FPL's Tier 1 agreement Section 3.4 requires 'Local Building Code Official inspection and certification of installation' confirming the installation 'was permitted, has been approved' as a general responsibility of the customer, with energization following 82% · utility interconnection instructions

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? 'The most recent edition of the National Electric Code NFPA 70' — no year is pinned; the code floats to whatever edition is current 90% · adopting ordinance (2025, OCR'd — scanned/no text layer)
• Which building code edition is in force? 'The most recent edition of the Florida Building Code — Building' (per Ordinance 2025-17); the County's separate Building Codes page states the 2023 Florida Building Code took effect 1 Jan 2024 as the version currently in force 88% · County department page + adopting ordinance
• Which fire code edition is in force? 'The latest edition of the Florida Fire Prevention Code, adopted by the State Fire Marshal' — adopted by reference pursuant to F.S. 633.208, no year pinned 88% · adopting ordinance (2025, OCR'd)
• Are there local amendments to any of the above? Yes — local amendments exist above the FBC/NEC/Fire Code baseline: the Walton County Wind-Borne Debris Regions and Basic Wind Speeds Map (adopted by reference, Ordinance 2007-43) sets locally-mapped wind speeds from 120 to 170 mph depending on location and Risk Category, well above many inland Florida baselines; and the Coastal Building Zone Ordinance (2007-53) requires a 140 mph engineered design and mandatory architect/engineer certification within that zone, which is a local overlay the base FBC does not itself draw 88% · County ordinance + adopted wind-speed map (2007-43)
• What is the installation judged against? The codes adopted by reference in Code Sec. 6-26 (most-recent-edition FBC/Residential/Existing Building/Accessibility/Energy/NEC/Plumbing/Mechanical/Fuel Gas/Fire Prevention Code) plus the County's own Wind-Borne Debris Regions and Basic Wind Speeds Map and Coastal Building Zone provisions where applicable 85% · adopting ordinance (2025, OCR'd)

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.

Nothing recorded for Walton County on this step yet — 1 question checked and found unpublished. The guidance above is general.

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? Not stated by the County in terms, but implied: rapid shutdown per NEC 690.12 has been a mandatory requirement of every NEC edition the County could currently be citing under its 'most recent edition' language (2017, 2020, and 2023 NEC all carry it) 55% · inference from adopting ordinance

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? FPL territory: two labels are required at the point of interconnection — an 'INTERCONNECTING METER CAN' placard ('WARNING / MULTI POWER SOURCES / ENTER SOURCES HERE', plus rated AC output current and nominal operating voltage) and a 'DER DISCONNECT SWITCH' placard ('GENERATION SYSTEM AC DISCONNECT', rated AC output current, nominal operating voltage). A battery storage placard reading 'Battery storage utilized in this facility' is also required if batteries are installed. CHELCO territory: no placard wording is published in CHELCO's own Net Metering Tariff, Technical Requirements, or Tier 1/2/3 instructions — only a documented disconnect-switch location is required, not a specific placard 82% · utility Electric Service Standards (OCR'd, embedded Type-3 font pages)
• Does the authority specify placard wording of its own? Yes for FPL territory (exact wording quoted at q38). Not found published for CHELCO territory 80% · utility Electric Service Standards (OCR'd)
• Does it specify letter height, colour or material? FPL: 'All labels must be permanent and weatherproof/UV resistant placard with engraved letters.' No specific letter height or colour is given in the text recovered. Not found for CHELCO 75% · utility Electric Service Standards (OCR'd)

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? FPL territory: the DER disconnect switch must be mounted separate from, but adjacent to (within 10 feet of), the FPL meter socket, with no locked gates, doors or fences between the two, and must remain accessible to FPL at all times; U.L. 1741-listed inverter-based Tier 1 systems are exempt from needing a customer-installed manual disconnect at all. CHELCO territory: only requires that the disconnect switch's 'electrical and physical location' be documented on the one-line diagram for non-inverter systems — no fixed distance/adjacency rule is published 82% · utility Electric Service Standards (OCR'd) + tariff Sheet 9.050
• Must equipment be on a specific approved list? Yes — equipment must be tested and listed by a nationally recognized testing laboratory to UL 1741 and comply with IEEE 1547 for both utilities operating in the county 88% · utility interconnection agreement + technical requirements
• Are batteries permitted, and under what conditions? FPL territory: batteries are permitted behind the meter with a UL 1741 NRTL certification and a mandatory placard 'Battery storage utilized in this facility'; batteries integrated with a renewable system may not export power; stand-alone backup batteries need no interconnection agreement but must not back-feed the grid; grid-charged/continuously-interconnected batteries need a Small Generator Interconnection Application. CHELCO territory: no battery-specific policy is published in CHELCO's Net Metering Tariff, Technical Requirements, or Tier instructions — checked all three, none mentions batteries/ESS 78% · utility Electric Service Standards (OCR'd)
• Is a ground mount treated as a structure? Yes, effectively — the County's own definition of 'Structure' in Ordinance 2025-17 Sec. 6-29(a)(1) is 'anything constructed or erected with a fixed location on and/or below the ground, measuring 30 inches above natural grade,' which a ground-mounted PV array would meet 65% · adopting ordinance definitions (OCR'd)

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? Phone — call the Building Department at (850) 892-8160, Monday–Friday, 8:00am–2:30pm. The County's EnerGov SelfService portal is also referenced for account/inspection functions on the Building Division page, but the phone number is the number the Inspections page itself gives for booking 75% · County department page

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 — the County performs its own final electrical ('Power') inspection 82% · County inspection checklist
• If delegated, to whom? Delegated only if the applicant elects a private provider under F.S. 553.791 — Walton County Ordinance 2023-28 gives a 55% fee discount when 'a private provider is used to perform building inspection services' and waives the plan-review fee entirely when a private provider performs plan review 82% · County ordinance (2023, OCR'd — scanned/no text layer)

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? General sequence per the County's Building Inspection Checklist: Footing → Plumbing Rough-In → Slab or Floor Framing → Sheathing/Nail-off → Window and Door Attachment → Framing (covers electrical, plumbing/gas, mechanical) → Power → C/O or C/C. For a straightforward roof-mount PV retrofit with no new structure, this would in practice reduce to a single final 'Power' (electrical) inspection, but the County does not publish a PV-specific abbreviated sequence 68% · County inspection 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.

• Is there a published inspection checklist? Yes, a published inspection checklist exists, but it is general (all trades/new construction), not solar-specific 78% · County inspection checklist
• What must be on site at inspection? 911 address posted on the structure, the Notice of Commencement (if job cost >$5,000) recorded and posted at the job site with the building permit card, and any final certifications applicable to the site (Coastal Building Zone final letter, V-Zone flood certification, septic final) before the Power inspection can be conducted 72% · County inspection checklist

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? Final — the County's inspection sequence ends in a 'C/O or C/C' (Certificate of Occupancy or Certificate of Completion) stage generically for all permits; a straightforward PV retrofit with no occupancy change would not need a new CO, so in practice a Final/Power inspection approval is the operative sign-off, though the County does not publish a PV-specific statement distinguishing the two 62% · County inspection checklist
• Who notifies the utility for PTO? The applicant/installer notifies the utility. CHELCO: 'Once your system has been inspected by the county building department, submit the following...' (the customer submits the interconnect agreement/application). FPL: the customer executes the Tier 1 Interconnection Agreement and is responsible for providing the local inspection certification (Sec. 3.4) — again customer/installer-initiated, not the County 82% · utility interconnection instructions
• Is there a re-inspection fee? $30.00 per trip per trade under the standing fee schedule (Resolution 2025-70 Sec. 1(h)) — but currently $0.00, because re-inspection fees fall within the Sec. 6-30(a)-(j) range abated to $0 by Resolution 2025-58/2025-70 through 30 Sep 2026 85% · fee resolution (OCR'd)
