City of South Pasadena

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% · municipal code
• What does this authority permit itself, and what does it delegate? Both 78% · department page
• Is a permit required for a residential rooftop PV system? Yes 95% · municipal code
• Is there a separate electrical permit, or is it combined? Combined 55% · municipal code
• Is a HOA or architectural approval required first? No (city-required approval); the California Solar Rights Act (Civil Code §714) separately preempts unreasonable private HOA/CC&R restrictions statewide. 80% · municipal code
• Is there a historic-district review? Yes -- but only for designated/inventoried cultural resources, not citywide 90% · municipal code
• Is a wind or windstorm certification required? No 80% · municipal code
• Is a Specific Use Permit or Council approval ever required? No, for a residential system within the expedited-eligible size (SPMC 9.24(d) requires administrative approval only, no Council or Commission hearing). A discretionary body IS involved if the property requires a Cultural Heritage Commission Certificate of Appropriateness (see Q25), or if the Fire Chief refers a matter under 14.5. 65% · municipal code
• Is there a system-size cap on residential generation? 10 kW AC / 30 kW thermal -- a GATE for the expedited/ministerial review path, not an absolute cap. Systems above that size fall outside the 'small residential rooftop solar energy system' definition and are not barred, but require standard (non-expedited) plan review. 85% · municipal code

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 60% · department page + municipal code
• Must the contractor be registered with this authority before applying? Yes 60% · municipal code
• Is a homeowner permitted to self-install and self-permit? Yes 80% · department 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.

• Is a structural PE stamp required, and at what threshold? No fixed numeric threshold codified; for the expedited-eligible ('small residential rooftop solar,' ≤10kW AC/30kW thermal) system, the applicant self-verifies structural adequacy via 'standard engineering evaluation techniques' with no stamped engineer letter required (SPMC 9.24(a)(1)); the Building Official otherwise retains general Article I discretion to require a licensed engineer/architect stamp on any submittal. 70% · municipal code
• Is an electrical PE stamp required, and at what threshold? No fixed threshold; SPMC 9.24(a)(2) lets the applicant self-verify the existing electrical system's adequacy at their own cost via 'standard electrical inspection techniques,' with no PE stamp required for expedited-eligible systems. 70% · municipal 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? OpenGov (South Pasadena Open Gov Customer Permit Portal) 90% · portal landing page
• Can the whole application be completed online? Yes 75% · department page
• What does a residential solar permit cost? No dedicated 'solar permit' fee line exists. Composite of the city's own current fee documents: Electrical permit issuance fee $41.35 + Power Apparatus tiered fee by kW rating (e.g. $29.86 for a system rated >3-10kW, from the LA County Electrical Fee Schedule the city has adopted as its own, eff. 1 Jul 2026) + Fire Dept's own named lines, Master Fee Schedule (Res. No. 8000, eff. 6 Jul 2026): 'Photovoltaic residential' plan review $456.00 (#235) and 'Photovoltaic residential' inspection $170.00 (#293). A representative small residential system therefore runs roughly $700 once fire plan review and inspection are included. 60% · fee schedule
• How is the fee calculated? Tiered 65% · fee schedule
• Is there a separate plan-check fee? Yes 85% · 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.

• Which utility handles interconnection here? Southern California Edison (SCE) 55% · CCA member map (city-side inference)
• Where does the utility sit in the sequence? After permit 65% · municipal code

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 90% · municipal code
• Which building code edition is in force? 2025 California Building Code (and 2025 CRC for one- and two-family dwellings), Title 24 Part 2 95% · municipal code
• Which fire code edition is in force? 2025 California Fire Code, Title 24 Part 9, with the 2025 California Wildland-Urban Interface Code (Title 24 Part 7) 95% · municipal code
• Are there local amendments to any of the above? Yes 90% · municipal code
• What is the installation judged against? The 2025 CEC/CBC/CRC as locally amended by SPMC ch.9 and ch.14; no PV-specific local technical amendment was found, so a residential PV install is judged against the unamended state code plus the ordinary administrative amendments (structural/electrical self-verification per 9.24(a), one consolidated inspection per 9.24(b)). 80% · municipal code

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? No local ridge-setback or fire-access-pathway amendment found; the unamended 2025 California Fire Code governs. 65% · 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, per the unamended 2023 NEC (§690.12) embedded in the 2025 CEC; no local amendment to rapid shutdown was found. 70% · municipal code (absence, control-proven)

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.

• Does the authority specify placard wording of its own? No 75% · municipal code (absence, control-proven)
• Does it specify letter height, colour or material? No 70% · municipal code (absence, control-proven)

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.

• Are batteries permitted, and under what conditions? Battery storage is permitted and is treated as regulated 'mechanical equipment' under the zoning code: SPMC 36.300.080 defines 'HVAC equipment, and other compressors, battery storage and associated generators, filters, pumps, and similar equipment installed outside of the exterior walls or roof of a building' as constituting a structure, subject to setback rules (no front-yard placement; side/rear setback allowed if screened; minimum 3 ft from any lot line) and screening/visibility rules if roof-mounted. Technical (fire-code) requirements for the battery itself are the unamended 2025 CFC Chapter 12 -- no local PV/ESS-specific fire amendment was found. 78% · municipal code
• Is there a separate ESS permit or inspection? Yes, apparently -- the city's own current Master Fee Schedule (Res. No. 8000) carries a distinct Fire Dept. 'Energy Storage system' inspection fee ($390, item #331) separate from a distinct 'Energy Storage Systems' operational-permit fee ($390, item #362 under 'Permits'), implying ESS is tracked and fee'd separately from PV. 70% · fee schedule
• Is a ground mount treated as a structure? Not directly addressed for PV specifically -- no dedicated ground-mount solar provision exists anywhere in the zoning code (Articles 1-4 and 7 searched for 'ground mount' + 'solar,' 'freestanding' + 'solar,' and 'photovoltaic': zero hits). By analogy, SPMC 36.300.080's opening clause treats any equipment 'installed outside of the exterior walls or roof of a building' as constituting a structure, which would likely extend to a ground-mount PV array's racking, but this is inference from a mechanical-equipment section, not a PV-specific citation. 50% · municipal code (absence)
• Is there a local rule on service upgrades or busbar sizing? No local rule found on service-upgrade review or busbar sizing. 65% · municipal code
• Is a specific mounting system or attachment spacing required? No local mounting-system or attachment-spacing amendment found. 60% · municipal code

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 / online form 80% · department 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% · municipal code
• If delegated, to whom? N/A -- not delegated; the city's own Building Official (and, for the consolidated inspection, its own Fire Chief) performs the final inspection (see Q52). 85% · 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? Application + fee submittal via OpenGov -> building official administrative review against the adopted checklist (no hearing) -> administrative approval and permit issuance -> construction -> ONE consolidated final inspection (building official, optionally joined by the fire chief) -> permit finalized -> applicant separately seeks utility permission/PTO. 80% · municipal code
• Is a rough-in or mid-roof inspection required? No 85% · 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? No public checklist could be located published on the city's website, despite SPMC 9.23(d) requiring the building division to 'adopt a checklist of all requirements with which small residential rooftop solar energy systems shall comply to be eligible for expedited review.' 55% · department page (absence)

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 signed/closed permit record); no Certificate of Occupancy is issued for a residential PV retrofit and no locally-named 'green tag' or letter process was found. 50% · municipal code (inference)
• Who notifies the utility for PTO? Installer/Applicant 90% · municipal code
• Is there a re-inspection fee? $49.62 55% · fee schedule
• How are corrections issued and cleared? Building official issues a written correction notice detailing all deficiencies in an incomplete application (SPMC 9.24(c)); if the (single) inspection fails, a subsequent inspection is authorized and does not have to conform to the 'one inspection only' limitation (9.24(b)). 80% · municipal code
