City of Union City

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 95% · authority's own page
• What does this authority permit itself, and what does it delegate? Both (Building and Electrical, in-house); Fire code compliance is delegated by contract to Alameda County Fire Department 90% · authority's own page
• Is a permit required for a residential rooftop PV system? Yes 95% · permit application form
• Is there a separate electrical permit, or is it combined? Combined 65% · fee schedule
• Is a HOA or architectural approval required first? Yes, where applicable — the City's own Construction Permit Application form asks 'Is your property part of a Home Owners Association Group?' and instructs the applicant to attach HOA approval if so 80% · permit application form
• Is a wind or windstorm certification required? No 65% · authority's own page
• Is a Specific Use Permit or Council approval ever required? No — California's Solar Rights Act (Gov. Code §65850.5) requires ministerial, non-discretionary review of compliant residential rooftop PV, which is consistent with Union City using SolarAPP+ for automated, non-discretionary permitting rather than a Council/SUP process 70% · authority's own page + state law inference

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 (state-licensed contractor or owner-builder) 80% · permit application form
• Must the contractor be registered with this authority before applying? No 60% · authority's own page
• Is a homeowner permitted to self-install and self-permit? Yes 90% · permit application form

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 solar-specific checklist is published; SolarAPP+ handles document collection for the automated track (design files uploaded to the SolarAPP+ portal). For the manual/OTC track, the general Construction Permit Application plus site plans, manufacturer spec sheets, and load calculations are the pattern the Building Division uses for comparable residential electrical work (its EV-charger handout requires: completed application, 3 sets of site/floor plans, 2 sets of manufacturer specs, 2 sets of load calcs). 55% · comparable authority document (EV charging handout)
• How many copies, and in what format? Not specified for solar specifically; the comparable EV-charger handout from the same division calls for 3 sets of site/floor plans (8.5x11 min) and 2 sets each of specs/load calcs; fire submittals under the same City require 3 sets max 24x36. 50% · comparable authority document
• Is a site plan required, and what must it show? Not published specifically for solar; general Building Division practice (per the comparable EV-charger handout) requires site/floor plans showing the property and equipment location as part of any electrical submittal. 50% · comparable authority document
• Is a one-line / three-line diagram required? Yes 75% · utility tariff
• Are string and conductor calculations required? Not published by the City as a submittal requirement; standard NEC Article 690 ampacity/conductor sizing applies as part of the adopted electrical code, but no City-specific checklist calling out string/conductor calculations was found 50% · inference from adopted code

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? SolarAPP+ for eligible residential retrofit PV/PV+storage systems; other permits are handled over-the-counter or by email at the Building Division counter (no general online permitting portal is named for non-solar work) 90% · authority's own page
• Can the whole application be completed online? Yes, for eligible SolarAPP+ projects (instant automated permit); non-eligible or non-solar work requires in-person or email submittal to the Building Division counter 90% · authority's own page
• What does a residential solar permit cost? $295.00 for the first 15kW plus $5.00 per kW above 15kW (residential), plus a $109 permit issuance fee; minimum permit fee is $209 95% · fee schedule
• How is the fee calculated? Per kW (tiered: flat $295 base for the first 15kW, then $5/kW above that) 90% · fee schedule
• Is there a separate plan-check fee? Ambiguous — a generic 'Plan Check: 100% of Building Permit Fee' line exists on the fee schedule, but it is not clear whether it applies on top of the flat/tiered residential Solar PV fee, which appears designed to be self-contained (especially for SolarAPP+ automated review). 55% · 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? 48 business hours for the automated SolarAPP+ review (email with the City permit number arrives within 48 business hours of submittal) 90% · authority's own page
• How long is an issued permit valid before it expires? 180 days (statewide default under the adopted California Building Code, absent a published local override) 60% · inference from adopted code family
• Which utility handles interconnection here? PG&E (Pacific Gas & Electric) 95% · authority's own document
• Where does the utility sit in the sequence? Parallel intake with permitting, but the utility's final step (Permission to Operate) does not issue until after the City's final electrical inspection is complete 80% · utility tariff

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? 2023 80% · authority's own page + statewide code-cycle inference
• Which building code edition is in force? 2025 California Building Code (Volumes 1 & 2) 90% · authority's own page
• Which fire code edition is in force? Contradicted between the City's own pages: the Building page lists the 2025 California Fire Code as part of its adopted-codes family, while the separate Fire-Permits page states 'Union City adopted the 2013 California Fire Code.' Not resolved — the municipal code itself (Title 15) could not be reached to check the actual current adopting ordinance. 45% · authority's own page (contradicts another authority page)
• Are there local amendments to any of the above? Yes 85% · authority's own page
• What is the installation judged against? The locally-amended 2025 California Building/Residential/Electrical/Mechanical/Plumbing/Energy/Green Building Standards Codes (Volumes 1 & 2), plus the 1997 California Administrative/Abatement/Housing/Security codes, per the Building Division's own adopted-codes statement 90% · authority's own page

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 City of Union City 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 under NEC 690.12 as adopted via the 2025 California Electrical Code (built on the 2023 NEC); no Union City amendment to the rapid-shutdown requirement was found, but the ordinance text itself could not be reached to fully rule one out 70% · authority's own page + adopted-code inference

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? Not separately specified by the City beyond what NEC Article 690/705 (2023 NEC, as adopted) requires by default (main service disconnect PV labeling, rapid-shutdown label, multiple-source-of-power placard, etc.); no City-specific placard bulletin was found on the Building or Solar-App pages 55% · inference from adopted code
• Is a site plan / facility map placard required, and what must it show? Not separately published by the City; the NEC's own rapid-shutdown labeling requirements (690.56/705.10, as adopted in the 2023 NEC base of the 2025 CEC) are the applicable baseline in the absence of a local facility-map placard bulletin 50% · inference from adopted code
• Does the UTILITY specify placards beyond the AHJ's? Yes — PG&E's Rule 21 tariff requires the interconnection disconnect switch to carry open/closed position markings, and if it is not adjacent to the point of common coupling, permanent signage identifying its location (and, if inside a locked premises, a PG&E-approved locking device plus contact-information signage) 85% · utility tariff
• Where must the labels be placed? At or near the Point of Common Coupling / point of interconnection, in a location reachable by PG&E personnel 24/7 without keys or special clearance for emergencies, and during normal business hours otherwise; if the disconnect is not adjacent to the PCC, PG&E requires separate location signage 75% · 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? Not given as a specific distance from the meter; PG&E's Rule 21 requires the visible/lockable disconnect to be near the Point of Common Coupling, readily accessible, and clearly marked, but does not state a fixed clearance from the meter itself in the sections reviewed 65% · utility tariff
• Must equipment be on a specific approved list? Yes, in the sense that interconnection/service equipment must be Certified/Listed (per NEC Article 100) suitable for its application and available fault current — the City has no separate 'approved products list' beyond that adopted-code and utility-tariff listing requirement 70% · utility tariff
• Are batteries permitted, and under what conditions? Yes — the City's own SolarApp+ page states the automated portal covers 'residential, roof-mounted, retrofit photovoltaic (PV) systems or photovoltaic (PV) systems with battery storage,' so battery/ESS is permitted bundled with a PV installation up to SolarAPP+'s national eligibility limits; the City does not publish its own separate ESS conditions beyond that 75% · authority's own page
• Is there a separate ESS permit or inspection? No — the Building fee schedule has only one 'Solar Photovoltaic Permit Fee' line (no separate battery/ESS fee), and the Solar-App page describes PV-with-storage as within the same SolarAPP+ track, implying a combined rather than separate ESS permit 80% · fee schedule + authority's own page
• Is there a local rule on service upgrades or busbar sizing? No PV-specific rule published. The Building Division's comparable EV-charging handout (same division/process) requires a load calculation for circuits ≥30A and a separate permit if the service panel must be upgraded — the same general practice would plausibly apply to a PV/battery interconnection needing a panel upgrade, but this is analogy, not a PV-specific city statement. 50% · comparable authority document

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 — (510) 487-0711 for Building inspections, (510) 675-5470 for Fire inspections 95% · department handout
• How much notice is required? 1 business day — inspections are scheduled for the next business day only, and must be called in before 3:00 p.m. the day before 95% · department handout
• Are same-day or AM/PM windows offered? Yes — AM (8:00am-12:00pm) or PM (12:00pm-4:00pm) windows can be requested, though the handout notes this is 'a request only' and not guaranteed 90% · department handout

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? Building/Electrical: No (performed in-house by the Building Division's own inspectors, confirmed by phone the day before). Fire: Delegated to Alameda County Fire Department under contract. 90% · department handout + authority's own page
• If delegated, to whom? Alameda County Fire Department (fire-related inspections/plan review only; building and electrical inspections remain in-house) 90% · authority's own page + delegate's own 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 published as a numbered sequence for solar specifically. By analogy to the Building Division's comparable EV-charger process: a single final inspection is performed unless the installation also requires a service-panel upgrade, in which case a rough inspection precedes the final. 55% · comparable authority document
• Is a rough-in or mid-roof inspection required? Only if a service-panel upgrade is part of the scope (per the comparable EV-charger process); otherwise a single final inspection is the norm for a retrofit PV system 55% · comparable authority document

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 75% · authority's own page (absence proven against its full document list)

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 (a final electrical/building inspection clearance) — inferred as the 'final electric inspection clearance from the Governmental Authority' that PG&E's own Rule 21 requires the applicant to submit before Permission to Operate is issued, but the City itself does not name the exact document type (e.g., 'green tag' vs. a letter) it issues on that pass 65% · utility tariff (inference); City itself is silent on the document form
• Who notifies the utility for PTO? Installer (Applicant) — PG&E's Rule 21 places the burden on the interconnection Applicant to submit the completed NEM interconnection request, the signed Generator Interconnection Agreement, and evidence of the AHJ's final inspection clearance to PG&E in order to obtain Permission to Operate 80% · utility tariff
• Is there a re-inspection fee? $220.00 per hour, 1-hour minimum 95% · fee schedule
