Union 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. Union County's own Building Department is the AHJ for building and electrical permitting for residential rooftop PV countywide, including inside the City of Lake Butler by explicit delegation from the city. 90% · department page
• What does this authority permit itself, and what does it delegate? The County permits and inspects both Building and Electrical itself, in-house, countywide (including inside Lake Butler by delegation). It delegates nothing further outward that I could find. Zoning/Planning & Development is also run by the county for unincorporated areas, but Lake Butler keeps its OWN Planning and Zoning function separate from the delegated Building function. 80% · city department page (cross-referencing county)
• Is a permit required for a residential rooftop PV system? Yes, almost certainly — no solar/PV exemption of any kind was found, and the county requires a standard Electrical Permit Application for electrical work generally. 55% · inference from general permit-application list
• Is there a separate electrical permit, or is it combined? Separate. The county lists 'Electrical Permit Application' as its own distinct application, separate from 'Residential Home Building or Addition Permit Application,' 'Roofing Permit Application,' etc. 78% · department page
• Is a wind or windstorm certification required? No wind/windstorm certification beyond the standard Florida Product Approval process is documented for this inland county; Union County is not in the Miami-Dade/Broward HVHZ and, being inland, is very unlikely to sit in the coastal ASCE 7 Wind-Borne Debris Region that some coastal counties are in. 50% · inference (state-level geography), not locally confirmed
• Is there a system-size cap on residential generation? No AHJ/zoning-based system-size cap on residential generation was found (the LDR, where such a cap would be codified, could not be extracted). At the UTILITY level, Clay Electric's own interconnection agreement effectively caps RGS size to no more than 90% of the member's utility service-entrance rating or 90% of the cooperative's transformer kVA capacity at that location, whichever is less, and requires Clay's engineering pre-approval for any system 20kW or larger. 60% · utility filed tariff (zoning half unconfirmed)

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? A Florida-licensed electrical contractor, per standard statewide practice — I could not confirm county-specific wording because the Electrical Permit Application PDF itself could not be extracted this session (see why). 45% · unreadable county PDF + general FL practice
• Must the contractor be registered with this authority before applying? Yes. The county publishes and requires BOTH a 'Certified Contractor Application' (for state-certified contractors registering locally) and a separate 'Registered Contractor Application' (for county/locally-registered contractors) before a contractor pulls permits. Notably, both forms are still live and listed on the county's current site (page lastmod 29 Jul 2026, i.e. more than a year after the 1 July 2025 state-direct licensing shift), so — directly answering the brief's standing question — Union County has NOT eliminated its own local contractor registration step for this authority. 70% · department page + sitemap lastmod

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? A general (not solar-specific) checklist titled 'Items Required to Obtain a Building or Addition Permit' exists and includes, among items I could partly make out at low resolution: a survey and legal description of property, a 911 address application, and proof of ownership/special-assessment tax card. I could not reliably read the remainder of the numbered list. 45% · county PDF (partial low-resolution read)
• How many copies, and in what format? Electronic only, via the Cloudpermit portal — the county's own description of Cloudpermit says applicants "complete the entire building permit process online on any mobile device," with no mention of a paper-copy option. 55% · department page
• Is a structural PE stamp required, and at what threshold? State floor: FS 471.003(2)(h) — no PE stamp is required for electrical work by a licensed electrical contractor where the work is valued at $125,000 or less and aggregate service capacity is 600 amperes (240V) or less on a residential system. I could not confirm whether Union's own Land Development Regulations impose a stricter local threshold (as at least five other Florida jurisdictions in this survey do) because that document could not be extracted this session. 60% · Florida Statute (state floor)
• Is an electrical PE stamp required, and at what threshold? Same state floor as q13: FS 471.003(2)(h), $125,000/600A. No stricter local rule confirmed. 60% · Florida Statute (state floor)

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? Cloudpermit (us.cloudpermit.com) — a cloud-based permitting platform the county says it has "partnered with." 95% · department page
• Can the whole application be completed online? Yes — per the county's own description, an applicant can apply for a permit, check permit/inspection status (with automatic email status-change alerts), schedule or cancel inspections, message the department, request permit changes, and pay by credit card, entirely online. 90% · department page

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? 7-10 business days for the Building Official to complete any necessary plan reviews; if no review is necessary, the permit can be issued in as little as up to 2 business days. 92% · department page
• How long is an issued permit valid before it expires? Not stated by the county; the statewide FBC administrative floor (Chapter 1, e.g. work must commence and inspections must not lapse within 180 days or the permit becomes invalid) would apply absent a stricter or more lenient local rule, but no Union-specific figure was found. 50% · state/FBC administrative floor, not locally confirmed
• Which utility handles interconnection here? Clay Electric Cooperative, Inc. is the utility documented with the highest confidence for this area (a member-owned cooperative under Fla. Stat. 366.91, headquartered in nearby Keystone Heights, with an active, current solar/net-metering program). I could NOT rule out Duke Energy Florida or FPL serving some parcels within the county, and could not confirm Clay specifically for Union County from a Union-specific source (no Franchises appendix in a Code of Ordinances was reachable, and the county's own Electrical Permit Application — which might carry a utility checkbox, the survey's best technique for this exact question — could not be read this session). 68% · utility website (own program pages)
• Where does the utility sit in the sequence? The AHJ inspects first: Clay Electric's own current Interconnection Agreement requires the Member to provide Clay with WRITTEN CERTIFICATION from the local code official that the installation has been inspected, permitted, and approved, BEFORE the RGS may operate. The Member must also notify Clay at least 10 days before the intended in-service date; Clay then installs its net meter (incurring a $60 trip fee) and may witness testing. 90% · utility filed 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? State floor: NEC 2020, effective 31 December 2023, under Florida Building Code 8th Edition (2023). Union's own material never states an NEC year by name. 72% · city page (county-served) + statewide floor
• Which building code edition is in force? Florida Building Code, 8th Edition (2023), effective 31 December 2023. 85% · city page (county-served)
• Which fire code edition is in force? State floor: Florida Fire Prevention Code, 8th Edition (2023). No county-specific fire-code document was reachable to confirm or contradict this locally (the county's own site has no dedicated Fire Department/Fire Code page). 50% · state floor; local absence checked via sitemap
• What is the installation judged against? Florida Building Code 8th Edition (2023) and (state floor) NEC 2020 — see q29/q30. 75% · city page (county-served) + statewide floor

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 Union 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 locally. Under the state-floor NEC 2020 adoption, rapid shutdown at the module level (NEC 690.12) would apply, since 2020 carries the module-level requirement (module-level rapid shutdown was introduced after NEC 2014, which had only the array-boundary requirement — see the CORRECTED BY RUN 60 note in the baseline this run was briefed on). 55% · inference from state-floor NEC 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 AHJ-specific placard requirement was found for Union County. At the UTILITY level, Clay Electric's current Interconnection Agreement requires a placard ONLY for battery storage: a label permanently affixed to the meter enclosure. No general PV/RGS placard is specified by either the AHJ or the utility. 80% · utility filed tariff
• Does the authority specify placard wording of its own? Clay Electric specifies exact wording for the ONE placard it requires (battery storage only): "Battery storage utilized in this facility." No general PV placard wording is specified by the utility or found for the AHJ. 90% · utility filed tariff
• Does it specify letter height, colour or material? No — Clay Electric's placard clause specifies wording only ("Battery storage utilized in this facility"), with no letter height, colour, or material requirement anywhere in the document. This is a genuine, directly-read absence, not a failure to find the document. 85% · utility filed tariff (proven absence)
• Does the UTILITY specify placards beyond the AHJ's? Yes — the utility (Clay Electric) is the only source of a placard requirement found in this survey run at all; the AHJ has none confirmed. 85% · utility filed tariff
• Where must the labels be placed? Clay Electric's battery-storage label must be "permanently affixed to the meter enclosure." No other AHJ or utility label-placement rule was found; the AC disconnect switch itself (not a label) must be "mounted separately from the meter socket" and "readily accessible at all times to the Cooperative" (see q48). 88% · utility filed 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? Per Clay Electric's own current Interconnection Agreement (Item 8), a manual disconnect switch is REQUIRED on every interconnected RGS regardless of size — no Tier-1-style size exemption exists for this co-op. At the Member's expense, it must be mounted SEPARATELY from the meter socket, be readily accessible AT ALL TIMES to the Cooperative, and be capable of being locked in the open position by the Cooperative. No specific distance figure is given (unlike FPL's 10 feet or SECO's 5 feet) — only "mounted separately." 95% · utility filed tariff
• Must equipment be on a specific approved list? At the utility-interconnection level: inverters/equipment must be certified by a Nationally Recognized Testing Laboratory (NRTL) to UL 1741 and comply with IEEE-1547 and the NEC; FSEC Std 203-05 approval is referenced as an applicable certification route where relevant. No separate AHJ-level equipment-listing requirement was confirmed. 85% · utility filed tariff
• Are batteries permitted, and under what conditions? Yes, batteries are permitted alongside an RGS, subject to Clay Electric's own conditions: NRTL/UL-1741 certified equipment; a permanent meter-enclosure label ("Battery storage utilized in this facility"); the battery may NOT export power to the cooperative's grid (behind-the-meter use / backup only, disconnected from the grid during outages); a UL-listed automatic transfer switch or special inverter is required. A battery system WITHOUT an accompanying RGS may charge from the grid but may NOT interconnect, per Rule 25-6.065(2)(d) F.A.C. as cited within Clay's own agreement (batteries alone are not "renewable energy"). 90% · utility filed tariff

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? Through the Cloudpermit portal, which the county's own page lists as supporting scheduling AND cancelling of inspections online; a phone/email route to the Building Department also exists. 80% · 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-house. The county names a single County-employed Building Inspector (Wilson Whidden/Whiddon, @unioncounty-fl.gov) and no private firm's name, letterhead, or staff email domain (e.g. SAFEbuilt, PDCS, CAP Government, JPI, M.T. Causley, Bureau Veritas, CGA Solutions, WILLDAN, ALPHA INSPECTIONS) was found anywhere on the county's or Lake Butler's own sites. 65% · named official + absence of private-firm signature (fallback test)
• If delegated, to whom? N/A — not delegated to a private firm; performed by the County's own Building Department (see q52). Building/electrical IS however delegated FROM the City of Lake Butler TO this same county department — see jurisdiction.holds. 65% · 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.

Nothing recorded for Union County on this step yet — 2 questions checked and found unpublished. The guidance above is general.

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? A general (not solar-specific) checklist, 'Items Required to Obtain a Building or Addition Permit,' exists on the county's site, but I could not reliably transcribe its full contents this session (see q8) and no solar/PV-specific inspection checklist was found. 45% · county PDF (partial read)

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.

• Who notifies the utility for PTO? The Member (customer/installer), not the AHJ, is responsible for notifying the utility: Clay Electric's own Interconnection Agreement (Item 4) requires the Member to notify the Cooperative at least 10 days prior to the RGS's in-service date, and Clay may then witness testing before/after the RGS is placed in service. 85% · utility filed tariff
• How are corrections issued and cleared? Likely via the Cloudpermit portal's messaging feature — the county's own description says Cloudpermit provides 'time-stamped messages' with the department and lets an applicant 'request and submit changes to an existing building permit.' Not solar-specific and not independently confirmed for corrections/re-inspection specifically. 55% · department page (general portal description)
