City of Oakland

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 - the City of Oakland (Bureau of Building, Planning and Building Department) is the AHJ for residential rooftop PV at any address inside the city 95% · adopting ordinance (Ord. 13332 C.M.S.)
• What does this authority permit itself, and what does it delegate? Both. One department holds building AND electrical: the Bureau of Building in the Planning and Building Department. Fire Prevention Bureau (Oakland Fire Department) is pulled in only for energy storage above published thresholds 95% · adopting ordinance (Ord. 13861 C.M.S., passed 15 Sep 2025)
• Is a permit required for a residential rooftop PV system? Yes 95% · department page + adopting ordinance
• Is there a separate electrical permit, or is it combined? Either - in practice combined. A rooftop PV job is issued as a single 'SE' (Solar Electric) permit that may also cover main-panel replacement, subpanels and the ESS; other electrical work not dedicated to the PV system needs a separate electrical permit. Ground-mounted, cantilevered or elevated arrays additionally need a separate Building Permit 90% · department page
• Is a HOA or architectural approval required first? No 92% · ordinance
• Is there a historic-district review? No 85% · planning code (Title 17, eff. 16 Jan 2024)
• Is a wind or windstorm certification required? No 90% · published checklist + ordinance
• Is a Specific Use Permit or Council approval ever required? Only exceptionally. OMC 15.33.090.A.1: if the building official makes a finding based on substantial evidence that the system 'could have a specific, adverse impact upon the public health or safety', the applicant may be required to apply for a use permit; and 15.33.090.A.2 bars denial of that use permit absent written findings of a specific adverse impact with no feasible mitigation. No City Council approval is ever required. Routine rooftop PV needs no Planning approval at all - Oakland's turnaround page lists new construction, alterations, demolitions, decks and ADUs as needing Planning approval before building intake, and does not list solar 90% · ordinance
• Is there a system-size cap on residential generation? No cap on system size. 10 kW AC is a threshold, not a limit: OMC 15.33.020 defines a 'small residential rooftop solar energy system' as 'no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal' on a single or duplex dwelling, and that is what qualifies for the expedited, non-discretionary, one-inspection process. Larger systems are permitted through the ordinary route. The SolarAPP+ instant route has its own electrical envelope: up to 400 A service, up to 200 A service disconnect, up to 225 A busbars, single-phase 240 V or 208 V, at most 2 string inverters, PV plus hardware not more than 4.0 psf 88% · ordinance + eligibility 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 - a California-licensed contractor (C-46 solar, C-10 electrical or B general as applicable under B&P Code Div. 3 Ch. 9) or the property owner as owner-builder. The SolarAPP+ instant route is restricted to 'California Licensed Contractors Only' 85% · department forms page + ordinance
• Must the contractor be registered with this authority before applying? No separate registration with the Bureau of Building. A CSLB licence is verified at application (Master Fee Schedule charges $45.67 for 'Verification of Proof of License and Workers Compensation Information Required by State Law'), and an Online Permit Center (Accela) account must be registered to apply online. Anyone doing business in Oakland separately owes the City business tax 70% · master fee schedule + department pages
• Is a homeowner permitted to self-install and self-permit? Yes 85% · department forms 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? Two routes. (A) SolarAPP+ eligible retrofit rooftop PV: SolarAPP+ approval number, SolarAPP+ Approval Document, SolarAPP+ Spec Sheet, Contractor's Declaration, then pay online. (B) Everything else (ground-mount, ballasted, commercial): site plans clearly identifying street and driveway; roof plans clearly identifying required fire access paths and location of street and driveway; framing details; structural calculations (ballasted, ground-mounted or elevated systems); mounting-system information; plus the Application for Solar Facilities and Self Certification Checklist. Ground-mounted/cantilevered/elevated systems also need a Building Worksheet and a separate Building Permit, which triggers a Green Halo recycling plan (WRRP) 90% · department page + published checklist
• How many copies, and in what format? Electronic only in practice: one compiled PDF plan set (PDF Portfolios rejected), first-generation vector PDF converted from CAD, all layers flattened, no colour except grey/hatched shading, landscape with north arrow, 4" x 3" clear space at top right for the City approval stamp; minimum sheet 24" x 36" for large construction and 18" x 24" for minor construction; supplemental documents at 8-1/2" x 11". Over-the-counter submittals are the same unzipped files on a thumb drive 90% · department page (submittal guidelines)
• Is a site plan required, and what must it show? Yes. Site plan to scale showing the entire property, all existing structures, dimensions, and the proposed solar energy system relative to the property lines and existing structures; illustrate the dimensions of the building and distance from the property line, and the system relative to the building edge. Separately a roof plan showing the entire roof with the system, clearly indicating code-required fire access paths including clearances at roof ridges, width of solar array, module layout(s), and roof attachment locations. The site plan must clearly identify the street and driveway 92% · published checklist (Bureau of Building, rev. 12/8/2020)
• Is a one-line / three-line diagram required? No - not on Oakland's own published solar submittal list. Neither the Application for Solar Facilities and Self Certification Checklist nor the solar page's 'Be prepared to provide' list asks for a one-line or three-line diagram; both are structural/site documents only. A single-line diagram IS required for energy storage (Code Bulletin CB23-001 item 6), and the SolarAPP+ route supplies electrical detail through the SolarAPP+ Spec Sheet 60% · published checklist + ordinance
• Are string and conductor calculations required? No 55% · published checklist
• Is a structural PE stamp required, and at what threshold? Yes, conditionally. 'Provide structural calculations for ballasted systems, ground-mounted systems, and any system elevated more than 24" above the roof. The design engineer needs to stamp and sign the structural calculations and plans.' No stamp is required for an ordinary flush-mounted rooftop retrofit. Two further triggers push a project out of the self-certification path: weight per attachment point greater than 45 lbs, or distributed weight of the PV system greater than 5 lbs/ft2 - both send the applicant to worksheet WKS1 90% · published checklist
• Is an electrical PE stamp required, and at what threshold? None published. Oakland publishes no electrical PE stamp threshold for residential PV. OMC 15.04.1.145.C only says that where plans ARE prepared by a registered design professional they must be signed and sealed; OMC 15.04.1.150 limits non-professional design by building type and structural complexity, not by electrical scope 70% · adopting 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? Accela Citizen Access, branded the 'Online Permit Center' (aca-prod.accela.com/OAKLAND), for the permit itself; SolarAPP+ (gosolarapp.org) for the automated code-compliance approval that feeds it; and an Oakland Inspection Request app (iOS/Android) plus a web scheduler at oakland-permits-portal.citygovapp.com for inspections 92% · portal landing page + department page
• Can the whole application be completed online? Yes 92% · department page
• What does a residential solar permit cost? $450.00 residential, plus $4.03 per kW above 15 kW. On top of that: a permit application fee of $21.49 (SolarApp+ Filing Fee) or $134.32 (online submission), and a Records Management & Technology Enhancement Fee of 12.70% of all fees. Commercial is $671.61 plus $5.37 per kW above 50 kW. A residential ESS permit, where taken separately, is $268.64 (no more than 80 kWh aggregate or 20 kWh single) or $389.53 above 80 kW 90% · published fee schedule (FY 2026-27, eff. 1 Jul 2026)
• How is the fee calculated? Flat, with a per-kW adder above 15 kW 92% · published fee schedule
• Is there a separate plan-check fee? No 65% · published 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? SolarAPP+ route: same day / instant - Oakland advertises 'same-day permits, cutting approval time by an average of 5 days'. Non-SolarAPP+ solar: 'Non-Solar APP + Energy Systems - 7 days or up to 2 weeks'. Where a separate Building Permit is triggered (ground-mount, elevated), Building Final Check adds '7 days or up to 3 weeks'. OMC 15.33.090.A binds the City to same-day for over-the-counter and 1-3 business days for electronic applications that meet the checklist 92% · department page (published turnaround times)
• How long is an issued permit valid before it expires? 720 days from date of issuance. A permit also becomes invalid if work is not commenced within 180 days of issuance, or if work is suspended or abandoned for 180 days; work that does not receive a major inspection and approval or partial approval within 180 days is deemed suspended or abandoned. The Building Official may grant one or more written extensions of not more than 180 days each on payment of the Master Fee Schedule fee 95% · adopting ordinance
• Which utility handles interconnection here? Pacific Gas and Electric Company (PG&E). Ava Community Energy (formerly East Bay Community Energy) is Oakland's default community choice aggregator but supplies GENERATION only - it does not run interconnection 95% · department page + utility page
• Where does the utility sit in the sequence? Parallel, with the utility gating the end. The PG&E interconnection application (Rule 21 / NBT) runs alongside permitting; the City's final sign-off is a precondition to PG&E granting Permission to Operate. Where the job also changes the electric SERVICE (new, upgrade, like-for-like, disconnect/reconnect), PG&E moves to the front: the City requires a site-specific PG&E AIC letter before it will schedule the inspection, and the permit must be issued before PG&E will produce the AIC letter 90% · department page + utility DG document

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 95% · adopting ordinance (Ord. 13861 C.M.S.)
• Which building code edition is in force? 2025 California Building Code and 2025 California Residential Code (Title 24 Parts 2 and 2.5, 2024 IBC/IRC base), effective 1 January 2026, with Oakland amendments in OMC 15.04. The 2025 California Wildland-Urban Interface Code (Part 7) and 2025 California Existing Building Code (Part 10) are adopted alongside 92% · adopting ordinance
• Which fire code edition is in force? 2025 California Fire Code, adopted and amended as OMC Chapter 15.12 by Ordinance No. 13870 C.M.S., adopted 16 December 2025 92% · adopting ordinance + municipal code
• Are there local amendments to any of the above? Yes - but none of them touch photovoltaics. Oakland has extensive local amendments (OMC 15.04 for building/electrical/mechanical/plumbing/WUI/existing-building, OMC 15.06 for energy and green codes, OMC 15.12 for the fire code). The electrical amendments are real but service-side: CEC 210.11(C)(1) (separate branch circuit per fixed appliance), 230.2 (extra service permitted for EV charging), 230.26 (point of attachment / periscope), 230.28 (RMC or IMC not less than 1-1/4 inch for overhead service), 230.29 (30 inch / 18 inch conduit projection limits), 230.43 (service-entrance conductors in RMC or IMC outside; Schedule 80 or 40 PVC underground), 600.1 (Oakland Sign Code), 760.1 (fire signalling), and a new Article 110-35 'SAFETY'. There is NO Oakland amendment to NEC Article 690 or 705, none to CRC R329 or R330, and none to CFC 1205 92% · adopting ordinance (full text read)
• What is the installation judged against? The 2025 California Electrical Code (2023 NEC) as adopted and amended by OMC 15.04 Article II Part 3 (administrative) and Article III Part 3 (technical), enforced by the Building Official; plus PG&E's Greenbook (TD-7001M) requirements for anything touching the service or meter, plus the manufacturer's listing and instructions 92% · adopting 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? The 2025 California Fire Code Section 1205 applies UNAMENDED - Oakland adopted no local ridge-setback or pathway rule. So the state CFC 1205 access pathways and ridge setbacks govern. Oakland's local layer is threefold: (a) the roof plan must 'clearly indicate code-required fire access paths, including clearances at roof ridges, width of solar array, module layout(s), and roof attachment locations'; (b) OMC 15.12 adds the California State Fire Marshal 'Solar Photovoltaic Installation Guideline' to CFC Chapter 80 referenced standards; (c) in the Wildland-Urban Interface / Very High Fire Hazard Severity Zone the state WUI provisions (CBC Chapter 7A, CRC R337, 2025 CA WUI Code Part 7) apply, the zone boundary is written street-by-street into OMC 15.04.1.180.Q, and OFD's Vegetation Management Unit inspects every parcel in the WUI Fire Area annually 88% · fire code as adopted (Ord. 13870) + municipal code

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 - NEC 690.12 of the 2023 NEC, as adopted by California as the 2025 CEC (Title 24 Part 3) and by Oakland as OMC 15.04 in force from 1 January 2026. There is no Oakland amendment to 690.12. Note the one Oakland-visible practical restriction: SolarAPP+ projects in Oakland may not satisfy rapid shutdown by the method 'No exposed wiring or conductive parts [690.12(B)(2)(3)]' 90% · adopting ordinance + eligibility 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? Whatever the 2023 NEC requires, and nothing beyond it from the City. The applicable placards are NEC 690.13, 690.56, 705.10 and 705.12 as adopted with no Oakland or California amendment. The one placard Oakland does spell out in its own words is for energy storage: 'A permanent plaque or directory denoting all electrical sources on or in the premises shall be installed at each service equipment location and locations of all electric power production sources capable of being interconnected, or at an approved readily visible location(s). The plaque or directory shall be marked with wording "CAUTION: MULTIPLE SOURCES OF POWER." Any posted diagrams shall be correctly oriented with respect to the diagram's location.' On top of the AHJ layer, PG&E requires permanent signage affixed to the meter panel (see Q42) 88% · code bulletin (Building Bureau / Fire Prevention Bureau CB23-001)
• Does the authority specify placard wording of its own? Yes - but only for energy storage, and only one string of wording: 'CAUTION: MULTIPLE SOURCES OF POWER.' For photovoltaics alone, No: Oakland publishes no placard wording of its own 85% · code bulletin + full enumeration of published bulletins and forms
• Does it specify letter height, colour or material? No - Oakland specifies no letter height, colour or material for any PV or ESS placard. The ESS bulletin requires a 'permanent plaque or directory' with the wording 'CAUTION: MULTIPLE SOURCES OF POWER' and requires posted diagrams to be 'correctly oriented with respect to the diagram's location', but sets no dimension, colour or substrate. The physical spec therefore falls back to NEC 110.21(B) (permanent, suitable for the environment, not handwritten) with no local addition. PG&E, not the City, supplies the only material word in play: 'engraved' (see Q42) 85% · adopting ordinance + code bulletin (proved absence with controls)
• Is a site plan / facility map placard required, and what must it show? Yes in substance, from two directions, neither of them an Oakland invention. (1) NEC 705.10 as adopted requires a permanent plaque or directory at each service equipment location denoting all electric power sources, and Oakland's ESS bulletin restates it with the requirement that 'Any posted diagrams shall be correctly oriented with respect to the diagram's location'. (2) PG&E requires signage AND a map at the meter panel where the AC disconnect is more than 10 feet away and out of line of sight; the map must show a direction indicator with the north direction arrowed, a plan view of the site, and the generator's AC disconnect and PG&E electric meter locations. Oakland itself publishes no site-plan placard specification 85% · utility DG manual + code bulletin
• Does the UTILITY specify placards beyond the AHJ's? Yes - PG&E is the source of the only PV signage spec with a physical property attached. Greenbook TD-7001M section 7.7: 'Customers who install distributed generation (e.g., solar, wind, battery storage) that is connected to the electric meter panel are required to install permanent signage affixed to the panel indicating an alternative source of generation is interconnected. ... Signage and maps also are required at the meter panel for the alternating current (ac) disconnect switch location when it is more than 10 feet away and out of the line of sight from the meter panel.' And for a supply-side (line-side) connection, Greenbook section 6.3: 'A fusible AC disconnect switch is required for generator interconnections ahead of the main breaker (line/supply side connection) and after the meter. Also required is an engraved placard (signage), indicating there is a line/supply side connection, installed on the metering equipment.' PG&E specifies the word 'engraved' and the word 'permanent'; it specifies no letter height or colour 92% · utility service requirements manual (PG&E Greenbook TD-7001M, eff. 22 Jun 2026)
• Where must the labels be placed? At the service equipment and at every electric power production source capable of being interconnected, or at an approved readily visible location - Oakland's ESS bulletin wording, which follows NEC 705.10. Where the ESS disconnecting means are not within sight of each other, 'placards or directories shall be installed at the locations of all disconnecting means indicating the location of all other disconnecting means. Disconnecting means shall be legibly marked in the field.' PG&E's own signage goes on the meter panel, and the supply-side engraved placard goes 'on the metering equipment' 88% · code bulletin + utility manual

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? Oakland sets no distance - the City has no AC-disconnect location rule of its own. PG&E's position must be read from two documents and is not the folklore. (1) Greenbook TD-7001M Table 6-3 'Requirements for AC Disconnect Switches': for an inverter-based generator on a single-phase self-contained socket-based meter panel of 320 amps or less (continuous current rating), an AC disconnect is NOT required at all - the commonest Oakland residential case. All other self-contained or transformer-rated meter panels: required. Footnote 1: 'An ac disconnect is required for all K-base meter panels of any ampacity rating.' Footnote 2: 'If an ac-disconnect switch is installed, it must be PG&E approved.' (2) Where one is installed, the Distribution Interconnection Handbook gives 10 feet as a DEFAULT with a documented alternative: the switch should be 'Located 10 feet or less from PG&E's electric meter at the point of interconnection (POI) and is seen easily from the panel', and item l allows it further away provided it 'Includes signage and a map showing the location of the ac disconnect switch'. The Greenbook states only the alternative form (signage and maps required when more than 10 feet away AND out of line of sight). Rule 21 itself sets no dimension. Do not confuse this with Greenbook 7.8, which requires the MAIN SERVICE disconnect - not the PV AC disconnect - to be 'adjacent to the meter(s), not more than 10 feet away and within line of sight' 92% · utility service requirements manual + interconnection handbook
• Must equipment be on a specific approved list? No general approved-products list from the City - equipment must be listed and labeled to the applicable UL standards under the adopted codes. Two specific list requirements do bite: (a) for energy storage, 'ESS shall be listed and labeled for use in accordance with UL 9540. UL 1741 and UL 1973 standards shall be applicable where appropriate. ESS listed and labeled solely for utility or commercial use shall not be used for residential applications'; inverters listed to UL 1741 or as part of the UL 9540 listing, and utility-interactive listing for grid-connected systems. (b) for the SolarAPP+ route, 'Modules and inverters must be listed in the California Energy Commission's database of approved equipment', as must energy storage systems and batteries 85% · code bulletin + eligibility checklist
• Are batteries permitted, and under what conditions? Yes, under a detailed local bulletin. Individual ESS units max 20 kWh. Aggregate limits: 40 kWh within utility closets and storage or utility spaces; 80 kWh in attached or detached garages and detached accessory structures; 80 kWh on exterior walls; 80 kWh outdoors on the ground. Permitted locations only: detached garages and detached accessory structures; attached garages separated per CRC R302.6; outdoors or on the exterior side of exterior walls not less than 3 feet from doors and windows directly entering the dwelling unit; enclosed utility closets, basements, storage or utility spaces within dwelling units with finished or noncombustible walls and ceilings (unfinished wood-framed walls and ceilings need not less than 5/8-inch Type X gypsum wallboard). 'ESS shall not be installed in sleeping rooms, closets, spaces opening directly into sleeping rooms or in habitable spaces of dwelling units.' Units separated by at least 3 feet unless UL 9540A large-scale fire testing documents less. Smoke alarms per CRC R314, or a listed heat detector where a smoke alarm cannot be listed for the location. Impact protection by approved barriers where subject to vehicle damage. ESS that can release toxic or highly toxic gas may not be installed in R-3 or R-4 92% · code bulletin CB23-001
• Is there a separate ESS permit or inspection? Yes, conditionally - and Oakland's own documents disagree on the trigger. An ESS installed as part of a solar job may be included in the solar (SE) permit application. A separate Fire Prevention Bureau approval is additionally required where, per the solar page, a single battery exceeds 20 kWh, or the aggregate exceeds 40 kWh in utility closets, sheds or basements, or 80 kWh is installed outside. The Master Fee Schedule prices a standalone ESS permit at $268.64 residential (no more than 80 kWh aggregate or 20 kWh single) and $389.53 above that. But the Bureau's inspection guide states a much lower trigger: 'Energy Storage Systems exceeding a combined 13.5KwH shall be approved by the City of Oakland Fire Prevention Bureau. For example, installing two Tesla Powerwalls would trigger compliance' 80% · department page + fee schedule + inspection guide
• Is a ground mount treated as a structure? Yes 90% · department page + published checklist
• Is there a local rule on service upgrades or busbar sizing? No busbar or 705.12 rule of Oakland's own - NEC 705.12 governs unamended. What Oakland does add on the service side: AFCI breakers required per CEC 210.12; a PG&E AIC letter is mandatory for every service change-out, upgrade, new service, disconnect/reconnect and like-for-like replacement before a green tag will issue; working clearances are enforced at 30" wide, 36" in front of the service dead-front, grade to 6-1/2 feet, measured to assumed property lines even where there is no fence, and to gas meters; service-entrance conductors must be in RMC or IMC outside the building (OMC 15.04.3.3030); and no more than one utility meter may be installed in the service equipment of a single-family dwelling without the Building Official's prior written authorization (15.04.2.375.D). SolarAPP+ in Oakland is limited to busbars up to 225 A 88% · department page + adopting ordinance
• Is a specific mounting system or attachment spacing required? No named product or fixed spacing, but Oakland requires the mounting system to be declared and self-certified against numeric thresholds. The checklist collects: mounting system manufacturer, product name and model; total weight of PV modules and rails; total number of attachment points; weight per attachment point (if greater than 45 lbs, see WKS1); maximum spacing between attachment points on a rail (per the product manual, based on maximum design wind speed); total module surface area; and distributed weight on the roof (if greater than 5 lbs/ft2, see WKS1). Framing details must show 'anchor type, diameter, spacing, and embedded depth into the framing'. SolarAPP+ eligibility adds: PV plus hardware not more than 4.0 psf, flush mounts limited to 10" above the roof on pitched (steeper than 2/12) surfaces, at least 20% of a tilt-up array under 2 feet, one racking system model only, no ballasted systems, no wood shake or wood shingle roofing with a new rooftop PV system 90% · 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.

• How is an inspection booked? Portal - plus app, phone and email. Inspections are booked through the Accela-backed web scheduler (oakland-permits-portal.citygovapp.com, Accela Citizen Access account required), the Oakland Inspection Request app for iOS or Android, by phone on (510) 238-3444, or by email to BBCode-inspect@oaklandca.gov. For a solar job you enter the site address and the SE permit number (e.g. SE23######). Two inspection types cannot be self-booked: 'Field Checks and Pre-Construction must be scheduled by phone'. Fire Prevention Bureau inspections are booked separately at FPBReceptionist@oaklandca.gov 92% · department page
• How much notice is required? 1 business day. OMC 15.04.2.370.C: 'Every request for inspection shall be filed at least one working day before such inspection is desired.' Separately, for a small residential rooftop solar system OMC 15.33.090.D binds the City the other way: 'An inspection will be scheduled within two (2) business days of a request.' Same-day is not offered, and cancellations after 10 AM still count as a used inspection 90% · adopting ordinance + department page
• Are same-day or AM/PM windows offered? No same-day and no AM/PM windows - a two-hour ETA instead. 'Inspectors provide a two (2) hour estimated time of arrival (ETA). Inspectors will call between 8-10A and provide the two (2) hour estimated time of arrival.' App users can see the ETA in the scheduling app. For anything involving a utility release: 'Same-day utility release inspections are not possible. Completed work must be ready for inspection no later than 3PM.' Overtime inspections can be requested on a separate form at Master Fee Schedule rates 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? Yes - Oakland performs its own 95% · ordinance
• If delegated, to whom? Not delegated. The only hand-off is to another City bureau, not outside the City: the Oakland Fire Department's Fire Prevention Bureau signs off energy storage above the published thresholds, and OMC 15.33.090.C folds even the fire-permit inspection into the Bureau of Building's single solar inspection for eligible small residential rooftop systems 90% · ordinance + 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.

• Which inspections are required, and in what order? For an eligible small residential rooftop system: one inspection, the Final, and nothing before it - 'only one inspection shall be required'. For projects outside that (ground-mount, elevated, cantilevered, or anything with a separate Building Permit) the enacted major-inspection sequence applies: Pre-Construction (required only for major projects over $250,000 valuation, encouraged otherwise), then Major Inspection - Foundation, then Major Inspection - Concrete Slab or Under Floor, then Major Inspection - Frame (Rough), then Major Inspection - Final. A final inspection is called in only when all related permits have an approved rough-in 92% · ordinance + department handouts
• Is a rough-in or mid-roof inspection required? No 85% · ordinance + department handouts

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, though none is solar-specific. Oakland publishes 'What to Expect during your City of Oakland Building Inspection' (Building Bureau, Permit Inspections Services), which has a 'Solar and Energy Storage Systems' section, an 'Electrical and Gas Utility Releases' section and a glossary of inspector terms; an 'Overview of City of Oakland Permit Inspection types' handout; and a Residential Repair Inspection Manual. On the submittal side there is the Application for Solar Facilities and Self Certification Checklist 88% · department inspection guide
• What must be on site at inspection? The printed permit and job card; complete, intact approved construction documents with all approved revisions; CF-1R (Title 24 energy) where applicable; Conditions of Approval; and for a SolarAPP+ job the printed permit and supporting documents including the SolarAPP+ approval documentation. Approved plans and job card must be printed in colour at the site. A person 18 years or older with direct knowledge of the project must be present and must provide safe access - ladders, lights, scaffolding as necessary. For anything touching the service: the site-specific PG&E AIC letter, without which no green tag will issue, and at final, PG&E lock-out tags on electrical meters.

• Does the inspector verify labels and listings? Yes - listings certainly, labels by strong inference rather than by a published statement. Oakland's inspection guide states 'All solar (PV) and Energy Storage systems (ESS) shall be installed as per approved plans, applicable codes, and manufacturer specifications', and the electrical final is described as covering 'fixture installation, ground wire connection and proper breakers, life safety'. Equipment listing is explicitly checked for ESS (UL 9540 / UL 1741 / UL 1973) and, on the SolarAPP+ route, against the CEC approved-equipment database. Code Bulletin CB23-001 requires the single-line diagram to 'indicate location and content of required signage', which the inspector then has in hand 70% · department inspection guide

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 - recorded as an approved Final inspection on the SE permit. Where the job also involves an electric service connection or reconnection, the physical artefact is a green tag: 'If the inspection passes, the City of Oakland will place a Green Tag on the Electrical Panel (no tag needed for Gas Service) and will release the meter to PG&E by next day at Noon.' No certificate of occupancy is issued for solar; Oakland issues a TCO/CO only for ground-up work, new units or a change of occupancy 88% · department page + ordinance
• Who notifies the utility for PTO? Installer. The contractor submits the signed final building/electrical permit - the 'final electric inspection clearance' - to PG&E through YourProjectsPortal (or NEMFollowups@pge.com for standard NEM under 30 kW solar and under 10 kW storage), and PG&E then grants Permission to Operate. There is one place where the City itself notifies PG&E, and it is not PTO: for an electric SERVICE connection or reconnection the City places the green tag and 'will release the meter to PG&E by next day at Noon', and under OMC 15.04.2.375.B PG&E may not set, reset, connect or reconnect a meter without 'written authorization from the Building Official or the Building Official's designated representative' 90% · utility DG document + ordinance
• Is there a re-inspection fee? $335.81 per inspection, listed as 'EXTRA INSPECTIONS' in the Planning & Building inspection fee section of the FY 2026-27 Master Fee Schedule, plus the 12.70% Records Management & Technology Enhancement Fee. The number of inspections included with the permit is tied to the project valuation: 'The number of free inspections you receive depends on your project's valuation. Failed inspections, cancellations after 10 AM, or in-field cancellations will still count as one inspection. If you need to pay for more inspections, call the Cashier at (510) 238-4774' 80% · published fee schedule + department page
• How are corrections issued and cleared? By emailed correction notice, cleared by paying for and scheduling a re-inspection. 'If a Correction is necessary or the inspection did not pass the Inspector will email the correction notice to the field contact/representative. Inspector can provide if requested code sections to support correction.' OMC 15.04.2.254 adds: 'To obtain a re-inspection, the applicant shall first pay the re-inspection fee as established in the Master Fee Schedule and then schedule a re-inspection', and 'no additional inspection of the work will be performed until the required fees have been paid' (15.04.2.370.E). At the plan-check stage an incomplete solar application gets 'a written correction notice detailing all deficiencies' under OMC 15.33.090.A 90% · department inspection guide + ordinance
