City of Belmont

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 + municipal code
• What does this authority permit itself, and what does it delegate? Both 90% · municipal code
• Is a permit required for a residential rooftop PV system? Yes 95% · authority's own bulletin
• Is there a separate electrical permit, or is it combined? Combined 78% · authority's own bulletin
• Is a HOA or architectural approval required first? No 95% · municipal code
• Is there a historic-district review? Reachable, but narrow: Belmont's historic-resource chapter (BCC Art. VII, §7-179–196) applies only to structures individually classified as a 'landmark or historic resource' by City Council resolution (§7-181) — not a blanket age- or district-based trigger. No solar-specific exemption exists, but §7-183 lets the Planning Director administratively approve 'minor alterations' (≤20% floor-area increase, retaining essential historic character) as part of the normal building-permit process, which would likely cover a rooftop PV retrofit on a classified property rather than requiring a full Certificate of Appropriateness. 75% · municipal code
• Is a wind or windstorm certification required? No 75% · authority's own bulletin (absence)
• Is a Specific Use Permit or Council approval ever required? A discretionary Use Permit may be required only if the Building Official makes written findings, based on substantial evidence, that the system 'could have a specific, adverse impact upon the public health and safety' with no feasible mitigation — otherwise the permit is ministerial. Council approval is not part of the residential solar path. 95% · municipal code
• Is there a system-size cap on residential generation? 10 kW AC (CEC rating) is a streamlined-path eligibility gate, not a hard cap — systems above it, or with batteries, simply fall out of the expedited process into standard plan review. No separate zoning-wide generation cap was found. 95% · authority's own bulletin

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 55% · secondary/state law inference
• Must the contractor be registered with this authority before applying? No 65% · authority's own bulletin (absence)
• Is a homeowner permitted to self-install and self-permit? Yes 55% · municipal code (absence) + state law inference

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? Completed permit application; demonstrated compliance with the Eligibility Checklist for Expedited PV; a completed Standard Electrical Plan (string or microinverter version) showing main/utility disconnect location, module/string counts, inverter/combiner make & model, one-line diagram, grounding/bonding and conductor specs, equipment cut sheets, CEC 690/705 labeling, and a site diagram (panel layout, north arrow, lot dimensions, distances to adjacent structures); a Structural Criteria worksheet if the roof doesn't self-certify. 95% · authority's own bulletin
• Is a site plan required, and what must it show? Yes — a site diagram showing arrangement of panels on the roof or ground, north arrow, lot dimensions, and distance from property lines to adjacent buildings/structures (existing and proposed). 95% · authority's own bulletin
• Is a one-line / three-line diagram required? Yes 95% · authority's own bulletin
• Are string and conductor calculations required? Yes 85% · authority's own standard plan form
• Is a structural PE stamp required, and at what threshold? Required only if the Structural Criteria worksheet fails: 'If one or more items are checked NO, attach project-specific drawings and calculations stamped and signed by a California-licensed Civil or Structural Engineer.' Otherwise the pre-approved anchor-spacing/rafter-span tables substitute for a stamp. 95% · authority's own bulletin

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? Symbium (automated SB 379 / Gov. Code §65850.52 portal, embedded at symbium.com/embed-search/?jurisdiction=belmont) for auto-issued residential solar/battery/EV permits; eTRAKiT for inspection scheduling and permit tracking. 90% · authority's own page
• Can the whole application be completed online? Yes 90% · authority's own page
• What does a residential solar permit cost? $450 flat, plus $15 per kilowatt above 15 kW 90% · fee schedule
• How is the fee calculated? Tiered 90% · fee schedule
• Is there a separate plan-check fee? No 70% · fee schedule + municipal code inference

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? 1 business day for walk-in/over-the-counter applications; 1–3 business days for electronic submittals. 95% · municipal code
• Which utility handles interconnection here? PG&E (Pacific Gas & Electric) 90% · authority's own page
• Where does the utility sit in the sequence? After permit 90% · 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? 2020 85% · municipal code (adopting ordinance)
• Which building code edition is in force? 2022 California Building Code (adopting the 2021 IBC with CA amendments), per BCC §7-22. 90% · municipal code (adopting ordinance)
• Which fire code edition is in force? 2022 California Fire Code (adopting the 2021 IFC with 2022 CA amendments) plus the 2021 International Wildland Urban Interface Code, per San Mateo Consolidated Fire Department Ordinance 2022-001, ratified by the City of Belmont in BCC §7-70(a) under Health & Safety Code §13869.7. 95% · municipal code (ratification ordinance)
• Are there local amendments to any of the above? Yes 90% · municipal code
• What is the installation judged against? The adopted 2022 CBC/CRC/CEC/CFC (with local amendments) plus the City's own Solar PV Standard Plan (string or microinverter), Structural Criteria worksheet, and Inspection Guide for PV Systems — Belmont judges eligible systems primarily against its own pre-approved standard plans rather than requiring project-specific engineering. 90% · authority's own bulletins

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? Hip roofs: 3-ft clear pathway eave-to-ridge; panels on both sides of a hip/valley must be ≥18in from it (adjacent placement allowed if only one side is populated); single ridges: two 3-ft pathways; panels no higher than 3ft below the ridge top for smoke-ventilation access. 65% · authority's own bulletin (dated content)

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? Required by the 2022 CEC (adopting the 2020 NEC, which includes §690.12 rapid shutdown) as a matter of adopted state code — but none of Belmont's own hosted PV documents (Eligibility Checklist, Submittal Requirements, Standard Plans, Structural Criteria, Inspection Guide) mention rapid shutdown or §690.12 anywhere; all are silent, consistent with their 2013-code-cycle template origin. 65% · municipal code inference + authority documents (absence)

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? WARNING: PHOTOVOLTAIC POWER SOURCE placard at the main service disconnect; PHOTOVOLTAIC SYSTEM DISCONNECT placards on AC/DC disconnects; DC DISCONNECT IS LOCATED... directory placard when DC disconnect is remote from main service; OPERATING CURRENT/VOLTAGE/MAX SYSTEM VOLTAGE/SHORT CIRCUIT CURRENT placard on DC disconnects; RATED AC OUTPUT/NORMAL OPERATING VOLTAGE placard at points of interconnection; a directory locating both disconnecting means; electric-shock-hazard placards on ungrounded-system enclosures and any equipment that stays energized in the open position; INVERTER OUTPUT CONNECTION - DO NOT RELOCATE on the inverter OCPD; and conduit/raceway PV-power-source markings every 10ft and at turns/penetrations. 85% · authority's own bulletin (dated content)
• Does the authority specify placard wording of its own? Yes 85% · authority's own bulletin
• Does it specify letter height, colour or material? 3/8-inch (9.5mm) minimum white letters on a red background for the PHOTOVOLTAIC POWER SOURCE markings; reflective, weather-resistant material; permanent and suitable for the environment for all required labels generally. 85% · authority's own bulletin
• Is a site plan / facility map placard required, and what must it show? Yes — the Eligibility Checklist requires 'a diagram of the roof layout of all panels, modules, clear access pathways and approximate locations of electrical disconnecting means and roof access points' as part of the fire-safety submittal requirements, functioning as the facility/roof-plan document referenced at inspection. 90% · authority's own bulletin
• Does the UTILITY specify placards beyond the AHJ's? PG&E's Rule 21 requires the visible manual isolating disconnect near the point of interconnection to 'include markings or signage that clearly indicates open and closed positions' — a utility-level marking requirement layered on top of the AHJ's placard set. A finer utility meter-proximity signage spec (if any) was not found in the public tariff. 70% · utility tariff
• Where must the labels be placed? Per the Inspection Guide's Table 1: at the main service disconnect (adjacent, clearly visible from where operated); on/at AC and DC disconnects; on DC disconnects and conduit/enclosures with ungrounded or energized-when-off circuits; on conduits/raceways/cable assemblies every 10ft, within 1ft of turns/bends, and within 1ft above/below penetrations; at points of interconnection; and on the inverter output OCPD. 85% · authority's own bulletin (dated content)

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? PG&E Rule 21 requires a visible, manually-operated isolating disconnect near the point of interconnection with clear open/closed markings, but no specific distance from the meter is stated in the public tariff text reviewed; a finer meter-proximity spec (if one exists) is understood industry-wide to live in PG&E's gated Greenbook/Electric Service Requirements documents, which are not publicly downloadable. 55% · utility tariff (partial)
• Must equipment be on a specific approved list? Yes 85% · authority's own bulletin
• Are batteries permitted, and under what conditions? Batteries are excluded from the streamlined/expedited PV path entirely (Eligibility Checklist item D requires the system be 'utility interactive and without battery storage' to qualify), so systems with batteries route to standard, non-expedited plan review; the San Mateo Consolidated Fire Department fee schedule separately lists 'Energy Storage Systems (ESS)' as a distinct $980/system reviewed item. 80% · authority's own bulletin + fire agency fee schedule
• Is there a separate ESS permit or inspection? Yes — SMCFD lists 'Energy Storage Systems (ESS)' as its own line item ($980/system) separate from 'Photovoltaic Systems' ($980/system) under Development Plan Review & Inspections, implying a distinct fire plan-review/inspection step for ESS that standard-eligible PV (fire-exempt under Belmont's own Submittal Requirements bulletin) does not trigger. 80% · fire agency fee schedule
• Is there a local rule on service upgrades or busbar sizing? No Belmont-specific busbar/service-upgrade amendment was found in the Electrical Code division (§7-41–43); the only busbar limit found is the streamlined-path eligibility criterion (225A max bus bar, single-phase 120/240V service) in the Eligibility Checklist, which is a state PV Toolkit-style figure, not a codified local amendment. 75% · municipal code + authority's own checklist
• Is a specific mounting system or attachment spacing required? Yes — a detailed flush-mount anchor-spacing/rafter-span specification. 90% · authority's own bulletin

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 90% · authority's own page
• Are same-day or AM/PM windows offered? Yes — AM inspections 9am-12pm, PM inspections 1pm-4pm. 95% · authority's own 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 90% · authority's own page
• If delegated, to whom? San Mateo Consolidated Fire Department, for the fire-inspection component only, when required. 90% · municipal code

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? Whenever possible, a single consolidated inspection covers the eligible PV installation; a separate fire inspection by SMCFD may be added if required. Failed installations may require additional, non-streamlined re-inspections. 90% · municipal code

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 95% · authority's own bulletin
• What must be on site at inspection? The approved plans (Standard Plan, site/roof diagram, equipment cut sheets) — the Inspection Guide repeatedly checks work 'according to the approved plan,' implying the approved plan set must be available/on-site for the inspector to compare against. 80% · authority's own bulletin (inference)
• Does the inspector verify labels and listings? Yes 90% · authority's own bulletin

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 (inspection approval/sign-off on the electrical permit) — Belmont's streamlined path issues an electrical permit and closes it on a passed final inspection; no Certificate of Occupancy is implicated for an existing-home PV retrofit. 65% · municipal code (inference)
• Who notifies the utility for PTO? Installer 75% · utility tariff
• Is there a re-inspection fee? $397/hour (general reinspection fee, minimum 1/2 hour) — no PV-specific re-inspection line was found separate from this general fee. 70% · fee schedule
