City of Rocklin

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% · department page
• What does this authority permit itself, and what does it delegate? Both 88% · department page
• Is a permit required for a residential rooftop PV system? Yes 97% · fee schedule
• Is there a separate electrical permit, or is it combined? Combined 72% · fee schedule
• Is a HOA or architectural approval required first? No local ordinance requirement found 68% · code search
• Is a wind or windstorm certification required? No — not applicable 82% · published checklist
• Is a Specific Use Permit or Council approval ever required? Not required for a standard residential rooftop PV system 68% · code search
• Is there a system-size cap on residential generation? No explicit residential system-size cap in city code; the City's own fee schedule uses the same 15kW AC threshold that CA Gov. Code §65850.5 uses to define a 'small residential rooftop solar energy system' eligible for expedited review — that is a fee/process breakpoint, not a hard cap on system size. 68% · fee schedule

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 78% · published checklist
• Must the contractor be registered with this authority before applying? Yes 90% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 75% · 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.

• What documents make up a complete submittal? Photovoltaic Checklist (signed/initialed), sample one-line diagram with derating calcs, sample site diagram, Solar Panel Dead Weight Loading Calculation, Verification of Wire Size form, CEC Table 310.15(B)(16) reference, PV roof clearance drawing, PG&E Greenbook Fig. 2-19, plus manufacturer cut sheets for all listed equipment. 96% · published checklist
• How many copies, and in what format? Two complete stapled plan sets, minimum 11"x17", scale ¼"=1' for structural/architectural and 1"=20' for site plans; all pages wet-signed by preparer, engineer/architect pages sealed and wet-signed. 96% · published checklist
• Is a site plan required, and what must it show? Yes — must show lot lines, structure locations, main service panel location, PV array configuration on roof (or lot if ground-mounted), % roof coverage, ridge-to-array distance, required access pathway, and locations of all PV equipment (arrays, combiner boxes, conduit, inverter, AC/DC disconnects). 96% · published checklist
• Is a one-line / three-line diagram required? Yes 96% · published checklist
• Are string and conductor calculations required? Yes 95% · published checklist
• Is a structural PE stamp required, and at what threshold? Structural plans must be stamped and signed (original) by a California Registered Engineer; the checklist lists this as a required packet item, though it reads as tied to non-standard/substituted mounting hardware or ground-mount foundations rather than universally to every listed, unmodified roof-mount racking system. 62% · published checklist
• Is an electrical PE stamp required, and at what threshold? Not required for PV-only systems (electrical work is under the installing electrician's/contractor's license, no PE stamp called out); an ESS added to the system DOES require the design be stamped/signed by a California Licensed Electrical Engineer. 80% · published 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? eTRAKiT (etrakit.rocklin.ca.us) 97% · portal landing page
• Can the whole application be completed online? Yes 85% · portal
• What does a residential solar permit cost? $450 flat for residential PV ≤15kW; $450 + $15/kW above 15kW if larger; ground-mounted residential PV is a separate $599 flat fee. 97% · fee schedule
• How is the fee calculated? Tiered 85% · fee schedule
• Is there a separate plan-check fee? No (appears bundled) 55% · 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.

• How long is an issued permit valid before it expires? Not separately published for PV; the City adopts the 2025 CBC/CRC 'in its entirety including the administrative regulations,' which carries the model code's standard permit-expiration provisions (inactivity/no inspection within the code-standard window). 58% · adopting ordinance
• Which utility handles interconnection here? Pacific Gas & Electric (PG&E) 92% · checklist referencing utility standard

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 62% · adopting ordinance
• Which building code edition is in force? 2025 California Building Code and 2025 California Residential Code (Title 24, Parts 2 and 2.5) 95% · adopting ordinance
• Which fire code edition is in force? 2025 California Fire Code (Title 24, Part 9) 95% · adopting ordinance
• Are there local amendments to any of the above? Yes, for the Fire Code only 88% · adopting ordinance
• What is the installation judged against? The current 2025 CEC Article 690 and 2025 CRC as locally adopted, plus the City's own PV/ESS submittal checklists and the PG&E Greenbook 85% · checklist + 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? Minimum 18" ridge setback where roof coverage is under 33%, 36" where coverage exceeds 33%; a continuous 36"-wide access pathway from eave to ridge is required on each array's roof plane. 96% · 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? Yes, required per CEC 690.12 (rapid shutdown of PV per the currently adopted 2025 CEC) 88% · 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? Yes — 'DUAL POWER SUPPLY / SOLAR ELECTRIC SYSTEM' warning tags at the meter panel and at the PV disconnect device, a 'CAUTION: SOLAR ELECTRIC CIRCUIT' tag at AC/DC circuit equipment, plus a permanent CEC 705.10 directory/plaque at the main service panel (additional battery-bank disconnect tag if ESS is present). 96% · published checklist
• Does the authority specify placard wording of its own? Yes 97% · published checklist
• Does it specify letter height, colour or material? Yes — red plastic material with engraved white letters, minimum 3/8" letter height; AC/DC conduit, raceway, enclosures, cable assemblies and junction boxes must use red background/white lettering, durable adhesive, reflective, weather-resistant, UL 969-rated material. 97% · published checklist
• Is a site plan / facility map placard required, and what must it show? A permanent directory/plaque at the main service equipment location listing every power-source disconnecting means (CEC 705.10) is required for both PV and ESS; no separate site-plan-style 'facility map' placard beyond that directory was found. 80% · published checklist
• Where must the labels be placed? Meter panel (warning tag), PV disconnect device (warning tag), AC & DC circuit equipment (caution tag), and battery-bank disconnect if present (critical-load tag); conduit/raceway/enclosures/junction boxes labeled along their run. 96% · 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.

• Where must the AC disconnect be, relative to the meter? Within 5 feet of the main service panel (up to 10 feet with structural justification for ESS, per the ESS checklist); no separate distance-from-meter figure was found, and city documents specify the disconnect's relationship to the main panel rather than to the meter itself. 72% · published checklist
• Must equipment be on a specific approved list? Yes 96% · published checklist
• Are batteries permitted, and under what conditions? Yes, under extensive conditions: garages (interior sidewall, not end wall, with clearance zones), or outdoors 3'+ from doors/windows, or enclosed utility closets/basements with 5/8" Type X gypsum if unfinished wood-framed; smoke and heat alarms required; vehicle-impact protection where applicable; multi-unit separation of 3'; disconnects within 5' (or up to 10' with structural justification) of the main service panel; UL 9540 listing; CRC R328 governs. 95% · published checklist
• Is there a separate ESS permit or inspection? Yes 96% · published checklist
• Is a ground mount treated as a structure? Yes 80% · fee schedule
• Is there a local rule on service upgrades or busbar sizing? No city-specific busbar rule beyond the standard CEC 705.12(B) 120%-of-busbar-rating limit for load-side interconnection, which the checklist calls out by citation. 80% · published checklist
• Is a specific mounting system or attachment spacing required? Yes — mounting cut sheets, bolt style/diameter/embedment length, attachment count per panel, and a 'Solar Panel Dead Weight Loading Calculation' are all required; substituted or mixed mounting components trigger additional engineering. 92% · 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? Phone 88% · department page
• How much notice is required? Same-day requests accepted if called in before 6 am; cancellations require notice before 8 am the same day or a re-inspection fee may apply. 80% · department page
• Are same-day or AM/PM windows offered? Yes — a 3-hour inspection window, viewable in eTRAKiT (or by phone) after 9 am the day of the inspection. 90% · 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 95% · department page
• If delegated, to whom? Not delegated — Building Division (building/electrical) and Fire Department (ESS) are both in-house City departments. 90% · 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.

Nothing recorded for City of Rocklin on this step yet — 2 questions checked and found unpublished. The guidance above is general.

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? Partially — the same 14-page PV Submittal Checklist doubles as the field reference (it has 'Initials' sign-off lines throughout), but there is no separately published inspection-only checklist. 55% · published checklist
• What must be on site at inspection? Approved plan set and the job/inspection card must be on site and visible; the project address must be visible from the street; all special-inspection/testing reports must already be uploaded to eTrakit beforehand — paper documents are no longer accepted at inspection. 92% · department page
• Does the inspector verify labels and listings? Yes (inferred) 65% · checklist / inferred practice

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 58% · inference from fee schedule / permit practice
• Is there a re-inspection fee? $176 (Building Division re-inspection fee); a separate $122 re-inspection fee applies on the Fire side. 90% · fee schedule
