City of East Palo Alto

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 85% · ordinance
• Is a permit required for a residential rooftop PV system? Yes 95% · ordinance
• Is there a separate electrical permit, or is it combined? Combined 80% · permit application form
• Is a HOA or architectural approval required first? Conditionally yes -- 'An approval letter from the Homeowner's Association (if applicable)' is listed as part of the Building Permit Application Requirements for solar. 80% · authority's own page
• Is there a historic-district review? No 85% · code of ordinances (full TOC + targeted grep)
• Is a wind or windstorm certification required? No 65% · ordinance
• Is a Specific Use Permit or Council approval ever required? No, for a compliant small system on a single/duplex-family dwelling -- MMC 15.12.020 makes the process administrative/ministerial (building official + fire marshal approve and issue permits directly, with no Planning Commission or Council step). Systems that exceed the 10 kW AC / 30 kW thermal cap, or that serve a use outside 'single- or duplex-family dwelling,' are not covered by this ministerial section and their process is not specified by the city. 70% · ordinance
• Is there a system-size cap on residential generation? Codified cap: 10 kW AC nameplate / 30 kW thermal, and the ordinance is scoped ONLY to systems 'installed on a single- or duplex-family dwelling' (MMC 15.12.020(A)(1)&(3)) -- the classic AB 2188-era ministerial-ordinance shape. No live city page (SolarAPP+, Symbium, or otherwise) was found publishing a higher ceiling; checked building.html and forms.html with passing positive/fabricated controls and found no SolarAPP+/Symbium reference at all. Separately, and in apparent tension with the cap's own height clause (panel 'does not exceed the maximum legal building height as defined by the authority having jurisdiction,' 15.12.020(A)(4)), the Development Code's own 'Height' definition (Ch. 18.08) EXCLUDES 'solar panels' from the height measurement altogether ('the vertical distance from the finished grade to the topmost point of a structure, excluding elevator equipment, ventilating and air conditioning equipment, solar panels and chimneys') -- an unresolved internal conflict between the two sections, reported rather than picked. 80% · 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 85% · permit application form
• Must the contractor be registered with this authority before applying? Yes 80% · permit application form
• Is a homeowner permitted to self-install and self-permit? Yes 85% · authority's own 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? Completed Building Permit Application; HOA approval letter (if applicable); confirmation/approved-and-stamped plans plus an approval letter from Menlo Park Fire District (submitted to MPFD before city submittal); site plan showing building and PV panel locations; equipment brochure with installation instructions and UL listing; roof plan (with tile/roofing weight noted if the roof structure needs upgrading). 90% · authority's own page
• How many copies, and in what format? Electronic PDF submittal by email to building@cityofepa.org (per the current Digital Submittal Requirements handout) -- no paper-copy count required under current practice. 75% · authority's own page
• Is a site plan required, and what must it show? Yes -- a site plan showing the location of the building and the location of the photovoltaic panels. 90% · published checklist
• Is a structural PE stamp required, and at what threshold? No PE stamp threshold is named; the codified ministerial ordinance instead requires the applicant to self-verify, using 'standard engineering evaluation techniques,' that the roof support structure is stable and adequate for the added wind/seismic/dead/live loads (a self-certification model, not a stamped submittal trigger). 85% · ordinance
• Is an electrical PE stamp required, and at what threshold? No PE stamp threshold is named; MMC 15.12.020(E)(2) requires the applicant, at their own cost, to verify using 'standard electrical inspection techniques' that the existing panel/subpanel and wiring can carry the added PV load -- again a self-certification, not a stamped-plan trigger. 85% · ordinance

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? No dedicated online permit portal / no SolarAPP+ or Symbium found. Building permit applications and supporting documents are submitted by email to building@cityofepa.org (or in person at the counter); the city's PV/building pages and forms page were both searched for 'SolarApp'/'Symbium' with zero hits against a passing positive control ('electrical': 1 and 9 hits respectively) and a passing fabricated control ('zzqqx': 0 hits). Note: Menlo Park Fire Protection District (the delegated fire reviewer) has its own separate Accela Citizen Access portal at aca-prod.accela.com/mpfd for its fire plan review -- that is MPFPD's portal, not the city's. 75% · authority's own page
• Can the whole application be completed online? No / partial 70% · permit application form
• What does a residential solar permit cost? $256 flat 90% · fee schedule
• How is the fee calculated? Flat 90% · fee schedule
• Is there a separate plan-check fee? No 65% · 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 solar-specific: the city's general practice statement is 'Projects that are not over the counter permits will go through the 30 day review process and two (2) week rechecks for resubmittals (if needed)'; staff otherwise contact applicants with next steps within two (2) business days of email submittal. Whether solar is treated as an over-the-counter item is not stated. 55% · authority's own page

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? Codified: 2022 CEC (based on the 2020 NEC) per MMC 15.12.010, last touched by Ord. No. 10-2022 (6 Dec 2022) and still showing in the Municode code as codified through Ordinance No. 07-2025 (21 Oct 2025). Live practice conflicts with this: the city's own Building Services page tells solar applicants to ensure the project 'complies with 2025 CBC' and links '2025 California Building Codes... using this link https://codes.iccsafe.org/codes/california' -- i.e. the statewide 2025 Title 24 cycle (2025 CEC, based on the 2023 NEC), effective 1 Jan 2026. This is a codifier-lag pattern: the live department guidance is ahead of the still-2022-dated electrical-code chapter. 75% · ordinance
• Which building code edition is in force? Live practice: 2025 CBC (city's own Building Services page: '2025 California Building Codes can be accessed using this link' and instructs solar applicants that the 'project complies with 2025 CBC'). Codified: still shows '2022 California Building Code' at MMC 15.08.010, last amended Dec 2022, unchanged through the Oct 2025 supplement -- the same lag as the electrical code. 75% · authority's own page
• Which fire code edition is in force? 2022 California Fire Code, per MMC 15.58.010 (last touched Ord. No. 10-2022, 6 Dec 2022), with MMC 15.58.020 ratifying Menlo Park Fire Protection District Ordinance No. 44-2022 as the local amendment. No live city page cites a newer edition for fire; MPFPD's own site and fee schedule likewise do not name a later edition. 75% · ordinance
• Are there local amendments to any of the above? Yes 85% · ordinance
• What is the installation judged against? The installation is judged against the adopted, locally-amended 2022 CBC/CRC/CEC/CFC/Energy Code (MMC Title 15, chapters 15.08/15.10/15.12/15.25/15.58) plus MMC 15.12.020's own solar-specific requirements (self-verified structural and electrical adequacy, UL-listed equipment, MPFPD fire sign-off) -- though the city's own live guidance for solar applicants directs compliance with the 2025 CBC, so day-to-day practice may already be on the newer cycle even though the codified chapters still read 2022. 70% · ordinance

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? Per CBC 3111/CRC R331 as reproduced in the city's own PV Inspection Checklist: hip roofs need a 3-ft-wide pathway from eave to ridge; single-ridge roofs need two 3-ft-wide accesses from eave to ridge; hips/valleys need 18 in. clearance on each side if panels are on both sides (panels may sit directly adjacent if only one side has panels); and panels/modules may be located no higher than 3 ft below the ridge. Applies to roofs steeper than a 2:12 slope. 90% · published 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? Required by virtue of the adopted code (2022 CEC, based on the 2020 NEC, which contains §690.12), but the city's own PV Inspection Checklist -- dated 21 Jan 2016 and apparently never updated -- never once uses the words 'rapid shutdown' or cites §690.12; it cites only 690.4, 690.5, 690.11, 690.14, 690.15, 690.43, 690.53, 690.54, 690.55, 690.56, 690.64, 705.10, 705.12, and 250.47. This is the same stale-handout pattern seen elsewhere: the code requires it, the city's own guidance document doesn't mention it by name. 65% · published 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? Full placard/label table given in the city's own PV Inspection Checklist: warning-shock-hazard label at the utility-interactive inverter & battery enclosure; an ungrounded-system warning at junction/combiner boxes and disconnects (if ungrounded); 'PHOTOVOLTAIC SYSTEM DC DISCONNECT' / 'PHOTOVOLTAIC SYSTEM AC DISCONNECT' labels; a rated-AC-output-current / normal-operating-AC-voltage label at the interconnection point; a disconnect-location directory at the service and inverter; a multiple-disconnect directory for multiple inverters; a DC-disconnect shock-hazard warning; an inverter-output-OCPD 'do not relocate' warning; 'WARNING: PHOTOVOLTAIC POWER SOURCE' markings on conduit/raceways every 10 ft and within 1 ft of turns/penetrations; and a battery-enclosure voltage/polarity label. 90% · published checklist
• Does the authority specify placard wording of its own? Yes 85% · published checklist
• Does it specify letter height, colour or material? No -- the checklist gives exact wording for each placard but specifies no letter height, colour, or material requirement anywhere in the document. 80% · published checklist
• Is a site plan / facility map placard required, and what must it show? Yes -- a disconnect-location directory ('a directory providing the location of the service disconnecting means and the photovoltaic system disconnecting means') is required at the electrical service and photovoltaic inverter if not co-located (CEC 690.56(B)/690.14(D)(4)/705.10), and a separate directory showing all AC/DC disconnect locations is required for systems with multiple inverters (CEC 690.4(H)/705.10). No standalone 'facility map' placard beyond this directory requirement is specified. 85% · published checklist
• Where must the labels be placed? Per the checklist's table: utility-interactive inverter & battery enclosure; junction boxes/combiner boxes/disconnects and other energized devices (ungrounded systems only); on the AC and DC disconnects; at interactive points of interconnection (usually the main service); at the electrical service and at the PV inverter (directory); on DC disconnects; on the inverter output OCPD; on conduit/raceways/enclosures at roof/ceiling assemblies, walls or barriers (every 10 ft and within 1 ft of turns/penetrations); and on the battery enclosure. 90% · published checklist

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.

• Must equipment be on a specific approved list? No dedicated city-specific 'approved equipment list' was found -- the only equipment-listing requirement stated by the city is a UL listing ('Equipment brochure with installation requirements and UL listing. The installation must meet the manufacturer's requirements'), a generic listing requirement rather than a jurisdiction-maintained approved-products list. 70% · authority's own page
• Are batteries permitted, and under what conditions? Batteries/ESS are permitted -- Menlo Park Fire Protection District's own current fee schedule carries distinct construction-permit lines for 'Battery Systems (includes cell sites)' ($356.42) and 'Energy storage system' ($510.15), plus an annual operational-permit line for 'Energy Storage Systems' ($395.05) -- confirming MPFPD reviews and permits ESS installations within East Palo Alto as part of its delegated fire role. Conditions themselves are governed by the adopted 2022 California Fire Code (as locally ratified via MMC 15.58.020/MPFPD Ordinance No. 44-2022) rather than by a separate city-published ESS handout; no dedicated East Palo Alto ESS handout was found on the Forms page. 70% · fee schedule
• Is there a separate ESS permit or inspection? Yes, at the fire-review level -- MPFPD's fee schedule shows both a separate construction-permit fee for battery/ESS systems and a separate ANNUAL operational permit fee for Energy Storage Systems, distinct from the PV construction-permit line. At the city Building Division level there is no separate 'ESS permit' type on the Building Permit Application; an ESS project would be submitted under the general building/electrical permit process. 70% · fee schedule
• Is a specific mounting system or attachment spacing required? General anchoring requirement only, no numeric spacing spec given by the city: 'Panels shall be adequately anchored to the roof framing' and 'Penetrations of the roof material shall be sealed in accordance with the roofing manufacturer's requirements.' No specific attachment-spacing table or approved mounting-system list is published. 75% · published 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.

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? Delegated (in part) 85% · ordinance
• If delegated, to whom? Menlo Park Fire Protection District (fire-safety inspection portion only; building/electrical inspection remains with the city). 85% · ordinance

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? Minimum two inspections under the codified expedited process: (1) an inspection of the solar PV racking system's roof attachments and watertight seals, then (2) a final inspection, which occurs only once the separate MPFPD fire-safety inspection has been completed. A subsequent (re-)inspection is authorized if the system fails. 85% · ordinance
• Is a rough-in or mid-roof inspection required? Yes 90% · ordinance

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% · published checklist
• What must be on site at inspection? Approved plans, the issued permit, and the manufacturer's installation instructions must be on site at time of inspection; all equipment must be open and ready for inspection. Separately, the general Building Services page states a 'Job card and approved plans (if applicable) are required to be on site for inspection. Sites not having proper documents will have to reschedule their inspection(s).' 85% · published checklist
• Does the inspector verify labels and listings? Yes (inferred) 70% · published 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 inspection, gating grid connection) -- MMC 15.12.020(H) frames the outcome as 'final inspection approval,' after which the applicant may seek utility permission to energize. No Certificate of Occupancy or 'green tag' terminology is used for solar in any city document found. 65% · ordinance
• Who notifies the utility for PTO? Installer 85% · ordinance
• Is there a re-inspection fee? $201 70% · fee schedule
• How are corrections issued and cleared? The Building Official issues a written correction notice detailing all deficiencies and any additional information needed for the application to be complete/expedited-eligible (MMC 15.12.020(G)); the PV Inspection Checklist separately states 'Field installation shall be per code/plan. Changes shall be submitted to the Building Division for approval prior to inspection.' 75% · ordinance
