City of Hayward

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 92% · department checklist
• What does this authority permit itself, and what does it delegate? Both 82% · fee/tax reference document
• Is a permit required for a residential rooftop PV system? Yes 98% · department checklist
• Is there a separate electrical permit, or is it combined? Combined 78% · fee schedule
• Is a HOA or architectural approval required first? No — not required by the City; the checklist's submittal list does not include HOA/architectural approval, and California's Solar Rights Act (Civil Code §714) restricts an HOA's ability to prohibit or unreasonably restrict residential solar 60% · department checklist (absence) + state law
• Is a wind or windstorm certification required? Yes, in substance — an engineer-stamped structural calculation verifying wind-load resistance is required whenever panels are mounted at an angle steeper than the roof (i.e., not flush) 88% · department checklist
• Is there a system-size cap on residential generation? No hard legal cap found; the 10 kW AC threshold in the checklist gates only which review track applies (over-the-counter 'Solar Tuesday' vs. standard review), not whether a system is allowed 80% · department checklist

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 (licensed C-10/C-46 contractor, or homeowner as owner-builder) 50% · inference from state law + department checklist silence
• Is a homeowner permitted to self-install and self-permit? Yes (via owner-builder), not confirmed as Hayward-specific 50% · inference from state law + department checklist silence

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? Roof plan (component locations, clearances, north arrow, designer contact, address, scope, applicable codes), attachment/structural details, single-line diagram, required-warning-label diagrams, and equipment cut sheets for every component shown 95% · department checklist
• How many copies, and in what format? 3 sets of plans, stapled together as a single set; cut sheets may be separate 92% · department checklist
• Is a site plan required, and what must it show? Yes — a roof plan showing required Fire Department access clearances, and the location of all system components (disconnects, service panel, inverter) 95% · department checklist
• Is a one-line / three-line diagram required? Yes — single-line diagram required, referencing CEC Articles 690 and 705 96% · department checklist
• Is a structural PE stamp required, and at what threshold? Yes, threshold = any panel tilted steeper than the roof pitch or non-flush mounting; flush-mounted panels are exempt 93% · department 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? EnerGov Self Service (Tyler Technologies) 92% · portal redirect, confirmed live
• Can the whole application be completed online? Yes — application submission, adding contractors, fee payment, permit download, inspection scheduling, inspector ETA tracking, and viewing inspection results are all described as available without an in-person visit 80% · department page
• What does a residential solar permit cost? $300 flat for residential flush-mounted systems (includes plan review and inspection); non-flush-mounted residential systems are also billed at the $300 flat PV rate but incur additional hourly plan-check charges for the required structural calculations 93% · adopted fee schedule
• How is the fee calculated? Flat 90% · adopted fee schedule
• Is there a separate plan-check fee? No separate plan-check line item for flush-mounted systems (bundled into the $300 flat fee); non-flush-mounted systems incur additional hourly plan-check charges rather than a second flat fee 85% · department checklist

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? Effectively same-week: reviewed over the counter each Tuesday 9:00-11:30am under the 'Solar Tuesday' program; if not submitted on a Tuesday, it is taken in and reviewed the following Tuesday 88% · department checklist
• How long is an issued permit valid before it expires? Not confirmed as a Hayward-specific figure; the statewide default under the adopted California Building Code (CBC §105.5) is that a permit expires if work does not commence within 180 days of issuance or is suspended for 180 days 50% · state code default; local amendment unverified
• Which utility handles interconnection here? Pacific Gas & Electric (PG&E) 65% · CCA utility's own statement + cross-jurisdiction consistency
• Where does the utility sit in the sequence? Parallel / No dependency at the permit-issuance stage — PG&E's interconnection application and PTO process run independently of the City's building-permit process; PTO is generally only granted after proof of the City's final inspection is provided 50% · inference from utility document + comparable jurisdiction

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 NEC, as adopted into the 2025 California Electrical Code (Title 24, Part 3), statewide effective 1 Jan 2026 52% · state adopting-agency page; NEC year inferred, local amendment unverified
• Which building code edition is in force? 2025 California Building Code (Title 24, Part 2), statewide effective 1 Jan 2026; Hayward's local amendment ordinance for the current cycle not verified 58% · state adopting-agency page; local amendment unverified
• Which fire code edition is in force? 2025 California Fire Code (Title 24, Part 9), statewide effective 1 Jan 2026; Hayward is confirmed to have its own fire ordinance in force (referenced by name in the City's own solar checklist) but its current-cycle amendment text was not retrievable 55% · department checklist (confirms a local fire ordinance exists) + state adoption cycle
• Are there local amendments to any of the above? Yes — Hayward has an established practice of adopting local amendments to state model codes: 2019 Ordinance No. 20-05 amended the California Energy Code and CALGreen (EV-charging provisions), and the solar checklist itself invokes a 'Hayward Fire Ordinance' for rooftop DC-disconnect placement. Current-cycle (2025) amendment text could not be retrieved. 68% · docketed ordinance text (2019 cycle) + department checklist reference to a fire ordinance
• What is the installation judged against? California Electrical Code (CEC) Articles 690 and 705 96% · department 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? 3 ft clear from ridges, 3 ft clear from side edges, and 18 in clear on either side of valleys 95% · department checklist

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 — if no other rapid-shutdown means is present, a rooftop DC disconnect must be provided at the roof within 3 ft of the PV array along the access pathway, 'per Hayward Fire Ordinance'; the main service panel must carry a 'PHOTOVOLTAIC SYSTEM EQUIPPED WITH RAPID SHUTDOWN' label. The document (revised 4-8-20) does not itself state which NEC/CEC edition's rapid-shutdown rule (690.12) it is keyed to, and predates the current 2023 NEC array-level rapid-shutdown requirements. 72% · department checklist

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? Solar-circuit label (conduit/raceways/enclosures/junction boxes), 'Solar Electric System' label at the main service disconnect, an inverter label, a directory plaque (if disconnects are not co-located), a rapid-shutdown label at the main service panel, and PG&E's own 'Utility AC Disconnect Switch' label at the AC disconnect 93% · department checklist + utility spec
• Does the authority specify placard wording of its own? Yes — the checklist reproduces exact required wording ('CAUTION: SOLAR CIRCUIT', 'CAUTION: SOLAR ELECTRIC SYSTEM', 'WARNING: ELECTRIC SHOCK HAZARD DO NOT TOUCH THE TERMINAL...', 'PHOTOVOLTAIC SYSTEM EQUIPPED WITH RAPID SHUTDOWN'), though this wording mirrors the standard CEC Article 690 model labels rather than being uniquely Hayward's own invented text 82% · department checklist
• Does it specify letter height, colour or material? Not specified by the City itself — the checklist shows label graphics with no callout for letter height, color, or material. PG&E's Greenbook (Doc 060559) requires its own AC-disconnect label to be 'engraved phenolic or comply with ANSI Z535.4,' with lettering 'a minimum 3/8" high and in all capitals' — a utility-level, not AHJ-level, specification. 80% · utility spec (PG&E Greenbook), City silent
• Is a site plan / facility map placard required, and what must it show? Yes — the City requires a directory plaque at the service and PV disconnecting means when they are NOT co-located (citing CEC Art. 690.56(B)); PG&E's Greenbook separately requires a location map when the AC disconnect switch is not grouped with the meter, and for a Net Generation Output Meter (NGOM) installation 85% · department checklist + utility spec
• Does the UTILITY specify placards beyond the AHJ's? Yes — PG&E's Greenbook (Doc 060559, Rev. #07, 3/25/2022) requires a permanently attached 'UTILITY AC DISCONNECT SWITCH' label, engraved phenolic or ANSI Z535.4-compliant, minimum 3/8-inch all-capital lettering, plus a location map/contact-info sign if the disconnect is not adjacent to the PG&E meter or not accessible outside a locked premises — none of which appears in the City's own checklist 95% · utility interconnection spec
• Where must the labels be placed? Per City checklist: solar-circuit label on conduits/raceways/junction boxes; 'solar electric system' label at the main service disconnect; inverter label at the inverter; directory plaque at the service/PV disconnect locations if not co-located; rapid-shutdown label at the main service panel. Per PG&E Greenbook: AC-disconnect-switch label on the switch's front face, within 10 ft/line-of-sight of the PG&E meter. 90% · department checklist + utility spec

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? Within 10 ft and in line of sight of PG&E's electric meter; must be at the same grade level if installed outdoors; wall- or pad-mounted units installed 48-75 inches above grade to the top of the enclosure; never on a roof, above-grade floor, or in a non-approved electric meter room 95% · utility interconnection spec
• Must equipment be on a specific approved list? Yes, at least for mounting hardware ('Only use listed mounting hardware'); PG&E's Greenbook separately requires disconnect switches be UL/NRTL certified and, up to 1200A, drawn from the Eaton/Siemens Safety Switch Cross-Reference Guides 82% · department checklist + utility spec
• Is a specific mounting system or attachment spacing required? No City-specified mounting system or attachment spacing; the requirement is to use only listed mounting hardware, verify component compatibility, and install per the manufacturer's instructions (flashing/counter-flashing at roof penetrations per manufacturer spec) 85% · department 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 — the EnerGov Self Service system is described as allowing applicants to 'schedule inspections' and 'check your inspector's estimated time of arrival (ETA)'; a phone route likely also exists via the Permit Center's main line (510-583-4140) but was not separately confirmed for inspection booking specifically 72% · department page description
• How much notice is required? Effectively next business day — must be requested before 11:30pm the night before the requested inspection day 88% · department checklist

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 88% · department checklist
• If delegated, to whom? Not delegated — performed by the City of Hayward Development Services Department Building Division 88% · department checklist

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? Plan submittal/review (Solar Tuesday or standard track) -> permit issuance -> construction -> Final Building Inspection, which covers the PV system's labels/components and a smoke/CO alarm check (or accepted self-certification in lieu of the alarm walk-through) 70% · department checklist
• Is a rough-in or mid-roof inspection required? No — the checklist describes only a single Final Building Inspection for a standard residential PV retrofit; no rough-in or mid-roof inspection stage is mentioned 62% · department checklist (absence)

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, in effect — the City's own 'Residential Solar Requirements' PDF functions as a published submittal-and-inspection-readiness checklist (drawing requirements plus final-inspection prerequisites); no separately named 'solar inspection checklist' document was found 65% · department checklist
• What must be on site at inspection? A safe ladder (free of defects, rated for a minimum of 250 pounds, extending 3 ft above the roof, secured to the building); the residence must be open for the smoke/CO alarm inspection unless a signed Smoke and Carbon Monoxide Alarm Self-Certification is submitted to the inspector at final 95% · department 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 — a passed Final Building Inspection closes out the PV alteration permit; no separate Certificate of Occupancy is issued for an accessory rooftop-PV permit on an existing single-family home 48% · department checklist (inference)
• Is there a re-inspection fee? No dedicated 'reinspection fee' line item found for building/solar permits; the FY2025 Master Fee Schedule's general 'Standard Hourly Rate' of $147/hour 'for plan check, inspections or other administrative services' (overtime rate $220.50/hr) would apply to any inspection beyond what the flat $300 PV fee covers 52% · adopted fee schedule (inference)
