St. Lucie 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 — St. Lucie County Building & Code Regulation Division is the AHJ for residential solar, but ONLY in the unincorporated area. Port St. Lucie, Fort Pierce, and the Town of St. Lucie Village each issue their own permits and are separate AHJs, not delegates of the county. 95% · department page
• What does this authority permit itself, and what does it delegate? Both — the County's Building & Code Regulation Division issues and inspects both Building and Electrical permits itself, but only in the unincorporated area. It does not delegate to the cities; Port St. Lucie, Fort Pierce and St. Lucie Village are independent, self-permitting AHJs sitting alongside the county, not under it. 92% · department page + adopting ordinance
• Is a permit required for a residential rooftop PV system? Yes, a permit is required for residential rooftop PV in the unincorporated county. 92% · department exemption list (checked for absence) + FAQ page
• Is there a separate electrical permit, or is it combined? Combined — Solar Photovoltaic PV System has its own single $75 permit-fee line item on the county's Residential Permits fee schedule, separate from the generic 'Electrical' line ($100), consistent with one combined Building/Electrical PV permit rather than the applicant pulling two separate permits. 65% · fee schedule
• Is a HOA or architectural approval required first? No — not required by the county as part of the building-permit process. Nothing in the LDC's Solar Energy section (7.10.28) or on the Permit Applications document list requires HOA/architectural-approval evidence for a permit, and Florida law (FS 163.04) already limits an HOA's ability to prohibit residential solar outright. 65% · ordinance (read in full for absence) + document list
• Is there a historic-district review? Only if the specific property carries an individual local historic designation. LDC §4.11.09 (Certificate of Appropriateness) requires COA approval before any exterior alteration — which would include rooftop PV — on a property 'designated pursuant to this ordinance,' and states 'No permit shall be issued by the County that affects any property designated pursuant to this ordinance without a Certificate of Appropriateness.' This is not a general requirement for all residential parcels — only individually-designated historic properties or contributing structures in a locally-designated historic district. 82% · ordinance
• Is a wind or windstorm certification required? Effectively yes in practice, though not stated as a solar-specific requirement. The county requires a signed/sealed 'Certification for Design Load Compliance, 8th Edition' (using ASCE 7-22 wind design) for most permits; the form allows an exemption only for interior renovations and 'certain minor building permits at the discretion of the plan reviewer' — so whether a given residential PV job needs formal wind certification is a plan-reviewer judgment call, not a blanket requirement or exemption. 68% · county structural certification form
• Is a Specific Use Permit or Council approval ever required? Yes, but only for utility-scale 'Solar Generation Stations,' never for ordinary residential rooftop/accessory PV. LDC §7.10.28(A)(1): Solar Generation Stations are a permitted use (Minor Site Plan only) in the AG-1, AG-2.5 and AG-5 agricultural districts; in any other zoning district a Solar Generation Station requires a Major Site Plan submitted concurrently with a Conditional Use Permit (i.e., Board of County Commissioners approval). 90% · ordinance
• Is there a system-size cap on residential generation? No kW/generation-capacity cap for residential accessory solar. Instead the county regulates by height and setback: roof-mounted panels are exempt from building-height limits but must sit >=3 ft from the roof edge; wall/building-integrated systems may not exceed 10 ft above the zoning district's max height; ground/pole-mounted systems are capped at 10 ft above the primary structure's base floor elevation, may encroach into side/rear setbacks only if <=6 ft tall and >=5 ft from the property line, and are barred from front/side-corner yards absent specific waiver conditions. 88% · ordinance

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 Florida state-licensed/certified electrical contractor, OR the homeowner acting as owner-builder under FS 489.103(7) if they own and occupy the home. 88% · department FAQ page
• Must the contractor be registered with this authority before applying? No — no separate local pre-registration/competency-card step is described for state-certified contractors. The county's Contractor Licensing division polices unlicensed-contractor complaints and licenses motor carriers, but its own page does not describe a registration requirement before a state-certified electrical/solar contractor can apply for a permit. 62% · department page
• Is a homeowner permitted to self-install and self-permit? Yes — a homeowner may self-permit and self-install as owner-builder under FS 489.103(7), provided they own and occupy the property; if they do not personally perform all trades, they must supervise and hire licensed subcontractors for electrical work. 90% · department FAQ 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? No dedicated solar/PV checklist is published. The county's Permit Checklists index lists exactly 7 checklists (Child Safety Barrier, Fence, New Single-Family Residence/Addition, Commercial Building, Marine Construction, Mobile Home, Mobile Home Worksheet, Owner Builder Flowchart) and none is solar-specific. A residential PV submittal therefore uses the generic Building Permit Application plus, where electrical work is involved, the county's Electrical Affidavit. 70% · department checklist index (absence proven)
• Is a structural PE stamp required, and at what threshold? No fixed numeric threshold found; the county requires a design professional's signed-and-sealed 'Certification for Design Load Compliance, 8th Edition' (ASCE 7-22 wind design) for most permits, but the form itself states it is 'not required for interior renovations...and certain minor building permits at the discretion of the plan reviewer' — i.e., whether a residential rooftop PV job needs the structural PE certification is a case-by-case call by the plan reviewer, not a published kW/weight/valuation threshold. 70% · county structural certification form

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 EnerGov 'Citizen Self Service' portal, linked from the county's permitting pages as 'St. Lucie County's Citizen Self Service (Tyler EnerGov)' at stlucieco.gov/CitizenSelfService. 95% · portal landing page
• Can the whole application be completed online? Yes for most of the process — apply, upload plans/documents, pay fees, check for review comments, and request inspections are all done through the EnerGov portal per the county's own Owner-Builder flowchart. The one in-person step is notarizing the Owner-Builder Affidavit (owner-builder route only) or appearing in person to sign the building permit as owner-builder. 80% · county process flowchart
• What does a residential solar permit cost? $75.00 flat, for the 'Solar Photovoltaic PV System' line item under Residential Permits. 80% · fee schedule
• How is the fee calculated? Flat fee ($75, regardless of system size/valuation) for the residential PV line item. 82% · fee schedule
• Is there a separate plan-check fee? No separate plan-check fee for residential — the fee schedule's Residential Permits section is headed 'Residential Plan Review & Permit Fees are based upon one- & two-family dwellings...' meaning the $75 solar line already bundles plan review and permit issuance. A distinct, value-based Plan Review fee schedule exists but is explicitly for 'Commercial and Miscellaneous' permits. 72% · fee schedule

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? Not stated specifically for solar. The county's general goal (per its Building FAQ) is a Building Permit within 14 workdays, but 'Minor permits are usually approved within 24-48 hours' — and a flat-fee, single-inspection-trip trade permit like residential PV is a strong fit for that minor-permit / 24-48-hour track rather than the 14-workday track. 60% · department FAQ page
• How long is an issued permit valid before it expires? 180 days — 'Permits expire and become null and void if work is not started and an inspection is not requested within 180 days. After work has commenced, the permit will expire when work is suspended or abandoned within the same time frames.' 85% · department FAQ page (contradicts HB 803 state floor — flagged)
• Which utility handles interconnection here? Split by location. Most of unincorporated St. Lucie County is served by Florida Power & Light (FPL). BUT Fort Pierce Utilities Authority (FPUA) — a municipally-owned electric utility — has an electric service area of about 35 sq mi, of which only ~14.7 sq mi is inside the Fort Pierce city limits; the remaining ~20 sq mi is OUTSIDE the city, in unincorporated communities such as Lakewood Park, White City, and the Fort Pierce North/South CDPs. Any address in those unincorporated pockets interconnects through FPUA, not FPL. 78% · utility's own service-area page
• Where does the utility sit in the sequence? After permit (with the interconnection application itself often filed in parallel). FPL's Tier 1 Interconnection Agreement requires 'the Customer agrees to provide Local Building Code Official inspection and certification of installation' confirming the install 'was permitted, has been approved, and has met all electrical and mechanical qualifications' before FPL will finalize interconnection/PTO. 78% · utility tariff / interconnection agreement

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 — adopted statewide via the Florida Building Code, 8th Edition (2023), Chapter 27 Electrical, which references NFPA 70-2020 by incorporation. This is a statewide adoption; St. Lucie County has not amended Chapter 27. 85% · adopting ordinance + state code cross-reference
• Which building code edition is in force? Florida Building Code, 8th Edition (2023), with St. Lucie County Administrative Amendments to Chapter 1 'Administration' of the Building Volume and Appendix Q 'Tiny Houses' of the Residential Volume. 95% · adopting ordinance
• Which fire code edition is in force? 'The most current edition of the Florida Fire Prevention Code (Chapter 69A-60, F.A.C.)' — the St. Lucie County Fire District adopts a floating/always-current edition rather than naming a fixed edition number, per its Fire Prevention Code Resolution. 85% · fire district resolution
• Are there local amendments to any of the above? Yes. Building: County Administrative Amendments to FBC Ch. 1 and Appendix Q (Ord. 2024-038). Fire: St. Lucie County Fire District amendments to special-hazard/access-roadway-clearance provisions (Res. 740-23) layered onto the 'most current' FFPC. Land Development Code: LDC §7.10.28 Solar Energy supplemental design standards apply on top of the base building/electrical code for siting, setback and height. 90% · adopting ordinances (combined)
• What is the installation judged against? FBC 8th Edition (2023) + NEC 2020 (via FBC Ch. 27) for construction/electrical compliance, plus LDC §7.10.28's solar-specific siting/height/setback standards for zoning compliance. No separate solar-specific electrical standard exists locally beyond the state-adopted NEC. 85% · ordinance (combined)

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 St. Lucie 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? Yes, rapid shutdown is required, to NEC 2020 Article 690.12 — the edition currently in force via FBC 8th Edition Ch. 27 (see q29). No county amendment to this requirement was found. 78% · inference from adopted code edition

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 county-specific placard list published. What is required comes from two places: (1) NEC 2020 Art. 690/705 rapid-shutdown and PV-source labels (statewide via FBC adoption), and (2) FPL's Tier 1 tariff, which requires a permanent weather-proof plaque adjacent to the meter socket if the manual disconnect switch cannot be sited there directly (§5.3). 72% · ordinance (absence) + utility tariff
• Does the authority specify placard wording of its own? No — the county does not specify its own placard wording. Wording follows NEC 2020's standard rapid-shutdown/label language (statewide); FPL's tariff requires a plaque that 'indicat[es] the location of the manual disconnect switch' but does not prescribe exact wording. 65% · ordinance (absence) + utility tariff
• Does it specify letter height, colour or material? Not specified locally. FPL's tariff requires the disconnect-location plaque to be 'permanent' and 'weather-proof' (i.e., material durability) but states nothing about letter height or colour; those specs (where they exist) come from NEC 2020 Art. 690.56 at the state level, not from St. Lucie County or FPL. 62% · utility tariff (partial) + ordinance (absence)
• Does the UTILITY specify placards beyond the AHJ's? Yes — FPL (Tier 1, <=10kW) requires a permanent, weather-proof plaque adjacent to its meter socket identifying the location of the manual disconnect switch whenever that switch cannot be mounted directly adjacent to the meter for safety/design reasons (§5.3). It also requires the visible-load-break manual disconnect itself to be lockable with a single FPL utility padlock (§5.2) for any Tier 1 system that is not a UL 1741-listed inverter-based system. 85% · utility tariff
• Where must the labels be placed? The manual disconnect switch (where required) must be mounted separate from, but adjacent to, the FPL meter socket, remain readily accessible to FPL, and be capable of being locked open with a single FPL utility padlock. If site conditions make an adjacent switch impractical, the switch may be relocated elsewhere on the premises PROVIDED a permanent weather-proof plaque is placed adjacent to the meter socket stating the switch's actual location. 85% · utility tariff

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? The AC (manual) disconnect switch must be mounted separate from, but immediately adjacent to, the FPL meter socket — readily accessible to FPL and lockable open with a single FPL padlock. (UL 1741-listed inverter-based Tier 1 systems are exempt from needing this separate switch at all, per §5.1.) 85% · utility DG/interconnection tariff
• Must equipment be on a specific approved list? Yes, for interconnection — FPL requires the customer-owned renewable-generation equipment to be 'submitted by a manufacturer to a nationally recognized testing and certification laboratory, and...tested and listed...for continuous interactive operation with an electric distribution system in compliance with...IEEE 1547, IEEE 1547.1, and UL 1741.' No separate county 'approved equipment list' exists beyond this utility-level listing requirement. 80% · utility tariff
• Are batteries permitted, and under what conditions? Not addressed by any St. Lucie County-specific ordinance found. Full-text search of the county's Code of Ordinances and Land Development Code for 'battery' and 'energy storage' returned only unrelated hits (definitions of unrelated terms, aircraft parking, wetlands storage, a communications-tower definition) — no residential ESS/battery permitting provision. Batteries are therefore governed only by whatever the (state-adopted) Florida Fire Prevention Code / NFPA 855 requires by reference, with no local amendment layered on top. 68% · full-text code search (absence proven with controls)
• Is there a separate ESS permit or inspection? No dedicated ESS/battery permit fee or line item is published — the Residential Permits fee schedule was read in full and contains no 'battery,' 'ESS' or 'energy storage' entry (closest is 'Generator Residential' at $125, a different equipment class). A battery add-on would most likely be folded into the Electrical ($100) or Solar Photovoltaic PV System ($75) line rather than triggering a separate permit type, but no document states this explicitly. 60% · fee schedule (absence proven)
• Is a ground mount treated as a structure? Yes, explicitly. 'All solar panels and devices are considered structures and subject to the requirements from the Land Development Code, together with all other applicable codes and ordinances.' 95% · ordinance
• Is a specific mounting system or attachment spacing required? Roof-mounted panels must be located at least 3 feet from the roof edge (LDC §7.10.28(B)(1), amended by Ord. 2024-29, 10-1-2024). No additional local rule on rail/attachment spacing was found beyond this edge setback and the general FBC 8th Ed./ASCE 7-22 wind-load requirements (see q13/q26). 85% · ordinance

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 (EnerGov Citizen Self Service, online) or Phone (a dedicated automated inspection line, (855) 636-0606 — caller needs their permit number ready). 75% · 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, in the unincorporated county — the county's own Building Inspectors perform the final inspection. This is 'Delegated' only in the sense that Port St. Lucie, Fort Pierce and St. Lucie Village are independent AHJs that inspect their own permits; the county does not delegate its unincorporated-area inspections to anyone. 90% · department page
• If delegated, to whom? Not applicable for the county's own unincorporated-area record — the county does not delegate its inspections. (For addresses inside Port St. Lucie, Fort Pierce, or St. Lucie Village, inspection sits with that city's own building department, which is a separate AHJ, not a delegate of the county.) 85% · department page

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? Not documented specifically for solar. The fee schedule states 'All permits include 1 inspection trip. If required, each additional inspection/trip is $75.00 each' — implying the standard PV permit is designed around a single Final inspection rather than a multi-stage rough-in/final sequence, but no county document names 'Final Electrical' or an inspection sequence for PV by name. 60% · fee schedule (inference)

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? No — proven absence. The Permit Checklists index (the exact place a published inspection checklist would appear) lists only application/submittal checklists (see q8) with no separate 'inspection checklist' for any trade, solar included. 78% · department checklist index (absence proven)

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? A Certificate of Occupancy (CO) for new construction; for retrofit/minor permits such as an existing-home solar installation, the county instead issues a Certificate of Completion (COC) upon request once all fees are paid and required inspections pass. 75% · department FAQ page
• Who notifies the utility for PTO? Installer/Customer — FPL's Tier 1 process requires 'the Customer shall provide FPL a completed application' to commence interconnection (§2.3), which in practice is filed by the installer on the homeowner's behalf; FPL's execution of the agreement (and, implicitly, PTO) additionally depends on the customer providing proof of local building-code-official inspection/certification (§3.4) — so the AHJ's role is limited to certifying the permit was approved, not to notifying the utility itself. 65% · utility tariff
• Is there a re-inspection fee? Tiered: $75 for the 1st re-inspection, $100 for the 2nd, $150 for the 3rd, and $150 for any re-inspection beyond the 3rd. A Stop Work Order reinstatement is a separate $100 fee. Private-provider permits get a 25% reduction on these fees. 82% · fee schedule
• How are corrections issued and cleared? Corrections/plan-review comments are posted to the applicant's EnerGov Citizen Self Service portal account for the applicant to check and respond to online ('Check for updates or required responses online' per the Owner-Builder flowchart); the fee schedule additionally charges a Plan Revision fee ($75 per revision, plus $25/extra page, escalating to 4x the original fee after the 3rd re-review of the same item) once a correction requires a resubmittal. 58% · process flowchart + fee schedule
