Town of Ross

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% · staff directory + ordinance
• What does this authority permit itself, and what does it delegate? Both 90% · department page + JPA site
• Is a permit required for a residential rooftop PV system? Yes 97% · fee schedule (PDF, extracted with pdftotext -layout)
• Is there a separate electrical permit, or is it combined? Combined 85% · fee schedule (PDF)
• Is a HOA or architectural approval required first? No for a standard flush roof-mounted system; Design Review IS triggered if the installation increases the existing roof height (or is part of a larger project already requiring Design Review). 75% · ordinance (PDF, control-checked absence)
• Is there a historic-district review? No 70% · municipal code title index (absence checked)
• Is a wind or windstorm certification required? No 75% · ordinance (PDF, absence checked)
• Is a Specific Use Permit or Council approval ever required? Only indirectly: a standard flush-mount residential PV system is reviewed ministerially under RMC Ch. 15.46 and never reaches Design Review or Town Council. A ground-mount or non-flush system that increases roof height would trigger Design Review under 18.41.020(a)(3), which can in turn be called up for Town Council review per 18.41.060. No Conditional/Specific Use Permit process applies to solar specifically. 65% · ordinance (PDF)
• Is there a system-size cap on residential generation? No fixed local kW cap. RMC 15.46.010(b) defines the systems eligible for this expedited chapter by cross-reference to the state definition in Government Code §65850.5(j)(3) ('small residential rooftop solar energy system'), rather than stating an independent Ross-specific ceiling. 80% · ordinance (PDF)

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? Any contractor 55% · published application form (PDF)
• Must the contractor be registered with this authority before applying? No 60% · department page (absence checked)
• Is a homeowner permitted to self-install and self-permit? Yes 50% · ordinance (absence checked) + general CA law

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? The Town has NOT published its own customized solar submittal checklist: the only document linked from the Building Department's solar section is the entire, unedited statewide 'California Solar Permitting Guidebook' (Winter 2019, 4th Ed., OPR), whose own Submittal Requirements Bulletin template still carries unfilled bracketed placeholders ('[LIST TYPE OF PERMIT(S) REQUIRED...]', '[WEBSITE ADDRESS]', '[PROVIDE CLEAR FEE SCHEDULE]', etc.). As posted, that generic bulletin calls for: completed permit application; eligibility-checklist compliance; a standard (or full) electrical plan showing disconnect location, module/string counts, inverter make/model, one-line diagram, conductor/conduit sizing, battery locations if any, equipment cut sheets, and CEC Art. 690/705 labeling; a roof/site plan showing panel layout, access pathways and required labels; and (for non-qualifying systems) stamped structural calculations. RMC 15.46.020(a)-(b) requires the Town to adopt AND publish its own conforming standard plan(s)/checklist(s) on its website — posting the whole un-customized state guidebook instead of the extracted, localized bulletin appears not to satisfy that requirement. 60% · published document (PDF, generic/unlocalized — read in full)
• How many copies, and in what format? Electronic submittal is available and an electronic signature is accepted in lieu of a wet signature for small residential rooftop solar applications, per the Town's own ordinance; the specific method/portal is 'as specified by the Building Official' and not further detailed in any published document found. General building applications may also be submitted in person or by email per the Building Department page. 80% · ordinance (PDF)
• Is a site plan required, and what must it show? Yes. As posted (via the un-customized statewide guidebook — see Q8), the required site/roof diagram must show: the arrangement of panels on the roof or ground, north arrow, lot dimensions, and distance from property lines to adjacent existing/proposed buildings; plus a roof plan showing roof layout, approximate roof-access point, code-compliant fire-access pathways, PV fire classification, and locations of all required labels/markings. Separately, RMC 14.04 §1201.4 (Ross's own Fire Code Ch. 12 amendment) independently requires 'a scaled and dimensioned site plan showing the location of all energy systems, property lines, buildings, service and electrical panels, transfer switches, disconnects, underground wiring and piping... map placard and signage' for any Energy System construction permit. 75% · ordinance (PDF, Ross's own local amendment)
• Is a one-line / three-line diagram required? Yes 65% · published document (PDF, generic/unlocalized)
• Are string and conductor calculations required? Yes 50% · published document (PDF, generic/unlocalized)

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 (Town of Ross 'Community Portal'), hosted at rossca-trk.aspgov.com 90% · portal landing page
• Can the whole application be completed online? Yes, for small residential rooftop solar specifically 70% · ordinance (PDF); portal itself returned 503 on this check
• What does a residential solar permit cost? $450 flat for residential PV ≤ 15 kW AC; $450 + $15/kW for each kW above 15 kW 95% · published fee schedule (PDF, current)
• How is the fee calculated? Tiered 90% · fee schedule (PDF)
• Is there a separate plan-check fee? No 90% · fee schedule (PDF)

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? Same day for over-the-counter applications; 1–3 business days for electronic applications (or 'as soon thereafter as may be practicable') — this is the Town's own solar-specific expedited standard, distinct from its general building-permit review time of approximately 4 to 6 weeks quoted for non-expedited projects. 92% · ordinance (PDF)
• How long is an issued permit valid before it expires? 12 months from issuance for projects valued at $200,000 or less (the typical range for a residential PV permit); 15/18/20 months for higher-valuation tiers up to and above $1,000,000; extendable by up to 90-180 days under specified findings. 85% · ordinance (PDF)
• Which utility handles interconnection here? Pacific Gas and Electric Company (PG&E) 88% · CCA member-communities page (confirms Ross's CCA status; PG&E is the distinct interconnecting utility)
• Where does the utility sit in the sequence? Parallel 78% · utility tariff (PG&E Electric Rule 21)

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 NEC, as incorporated into the 2022 California Electrical Code 55% · ordinance (PDF, dated Dec 2022) vs. current department webpage (discrepancy flagged)
• Which building code edition is in force? 2022 California Building Code (based on 2018 IBC) per the Town's own codified Ch. 15.05 (Ord. 718, 2022) — but see discrepancy: the Town's current 'Building Codes' webpage states the 2025 California Building Standards Code took effect statewide 1 Jan 2026, and no newer Ross ordinance updating Ch. 15.05 was found in the Town's own code library as of this survey. 55% · ordinance (PDF) vs. current department webpage (discrepancy flagged)
• Which fire code edition is in force? 2022 California Fire Code per the Town's own codified Ch. 14.04 (dated Dec 2022). A fellow Ross Valley Fire Department member agency, Sleepy Hollow Fire Protection District, has already moved to the 2025 cycle under its own Ordinance 2025-04 (per RVFD's fire-code page), while Ross's own posted fire-code chapter has not been updated to match — an internal lag among JPA member agencies, not just a Ross-vs-website gap. 60% · ordinance (PDF) + JPA department page
• Are there local amendments to any of the above? Yes 95% · ordinance (PDF)
• What is the installation judged against? The adopted, locally amended 2022 California Building Code, 2022 California Residential Code, 2022 California Electrical Code and 2022 California Energy Code (Title 15), plus the 2022 California Fire Code's locally added Chapter 12 'Energy Systems' provisions (signage/disconnect/shutdown-test requirements) and RMC Ch. 15.46's ministerial checklist for small residential rooftop solar. See Q29-31 for the live-page-vs-codified discrepancy on which code cycle is currently controlling. 80% · ordinance (PDF)

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 amendment to the CFC's access-pathway/ridge-setback provisions (Section 605) was found in Ross's own fire code — meaning the default, un-amended 2022 California Fire Code pathway/setback requirements apply as adopted, without a Ross-specific modification. 65% · ordinance (PDF, control-checked absence)

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? Rapid shutdown is required to whichever NEC edition is currently in force via the adopted CEC (NEC §690.12) — but Ross's own codified text contains no independent local statement of this requirement. 70% · ordinance (PDF, control-checked 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? Caution signs/labels at the main service panel and on disconnect equipment identifying the quantity and type of additional power source(s) on site, plus a required, clearly labeled, independent exterior disconnect located as close as possible to the main service panel. 90% · ordinance (PDF, Ross's own local fire-code amendment)
• Does the authority specify placard wording of its own? No 85% · ordinance (PDF, control-checked absence)
• Does it specify letter height, colour or material? Not specified 80% · ordinance (PDF, control-checked absence)
• Is a site plan / facility map placard required, and what must it show? Yes. RMC 14.04 §1201.4 requires, as part of the construction-document submittal for any Energy System, 'a scaled and dimensioned site plan showing the location of all energy systems, property lines, buildings, service and electrical panels, transfer switches, disconnects, underground wiring and piping, fuel type and piping, map placard and signage,' and the plan 'shall clearly designate property frontage for viewer orientation.' 85% · ordinance (PDF)
• Where must the labels be placed? At the main service panel and on the disconnect equipment (per Fire Code §1201.5), with the required independent exterior disconnect itself located 'as close as possible to the main service panel' per §1201.6. 85% · ordinance (PDF)

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? Ross's own Fire Code requires the independent exterior AC disconnect to be 'installed as close as possible to the main service panel or as approved by the fire code official' — i.e., co-located at/adjacent to the main service equipment. No Ross-specific or PG&E-specific meter-relative dimension (e.g., a maximum distance) was found in this run. 70% · ordinance (PDF)
• Must equipment be on a specific approved list? Yes (inferred) 55% · inference from adopted electrical code (no Ross-specific list found)
• Are batteries permitted, and under what conditions? Yes. Battery/energy storage systems are recognized and separately fee-lined by Ross's fire authority (Ross Valley Fire Department: 'Battery Systems $465' as a distinct construction-permit fee from 'Photovoltaic Power System $328'). Ross's own Fire Code Ch. 12 amendment (§1201.7) requires new alternate-power installations — including 'energy storage systems' — to be tested for complete shutdown, and §1201.5/1201.6 apply the same signage/disconnect requirements to batteries as to PV. No specific siting, clearance, or quantity limits for residential ESS were found in Ross's own code (control-checked: no 'kWh' or clearance figures in 14.04 or 15.46). 70% · utility/JPA fee schedule (live page) + ordinance (PDF)
• Is there a separate ESS permit or inspection? Yes 80% · JPA fee schedule (live page, raw HTML extracted)
• Is there a local rule on service upgrades or busbar sizing? No local rule found 80% · ordinance (PDF, control-checked absence)
• Is a specific mounting system or attachment spacing required? No prescriptive attachment-spacing rule found, but the zoning code does address flush-mount placement for setback purposes: RMC 18.40.090(d) permits 'roof mounted solar collectors installed substantially at the same angle as the roof pitch and within a foot of the surface of the roof' to be located within otherwise-required side and rear yard setbacks on primary structures — a de facto flush-mount definition used to grant a setback exception, not a structural mounting-system specification. 70% · ordinance (PDF)

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? Electronic submittal (per the Building Official's specified method) for small residential rooftop solar inspection requests; general building inspections are booked by phone (Building Department ext. 117/170). 80% · ordinance (PDF) + department pages
• How much notice is required? The Building Official 'shall strive to schedule an inspection within two (2) business days of a request' for small residential rooftop solar — read as the Town's own target turnaround rather than a stated advance-notice requirement. 75% · ordinance (PDF)
• Are same-day or AM/PM windows offered? A two-hour inspection window is promised for small residential rooftop solar inspections. General building inspections town-wide are scheduled mornings only, Monday through Thursday. 80% · ordinance (PDF) + 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 65% · ordinance (PDF) + JPA fee schedule (live page)
• If delegated, to whom? Ross Valley Fire Department (Joint Powers Authority serving Ross, Fairfax, San Anselmo and Sleepy Hollow FPD) appears to retain an independent fire-safety review/inspection role for PV and Battery Systems, based on its own separate fee lines, though no published Town–RVFD agreement (or absence of one) was located to confirm this definitively either way. 60% · JPA fee schedule (live page) + ordinance (PDF)

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 a standard expedited-eligible small residential rooftop solar system: one building/electrical final inspection by the Town (per RMC 15.46.040(b)), with a possible separate, independent fire-safety inspection by Ross Valley Fire Department (see Q52/53). No rough-in/mid-roof inspection is required under the expedited chapter. 75% · ordinance (PDF)
• Is a rough-in or mid-roof inspection required? No 90% · ordinance (PDF)

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 70% · published document (PDF, generic/unlocalized — absence of a Ross-specific checklist confirmed by reading the whole posted document)
• What must be on site at inspection? Approved, stamped plans and the permit's conditions of approval must be readily available on site for all inspections (per Ross Valley Fire Department's own instructions); no separate Town-specific on-site document list beyond the approved plan set was found. 65% · JPA department page
• Does the inspector verify labels and listings? Yes (inferred) 60% · ordinance (PDF, inferred from signage/testing requirements)

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 (building final inspection sign-off) 55% · inference from ordinance structure; no explicit Ross statement found
• Who notifies the utility for PTO? Installer 62% · utility tariff (PG&E Electric Rule 21)
• Is there a re-inspection fee? No PV-specific re-inspection fee line exists; the closest applicable published figure is the general 'Electrical, Mechanical, and Plumbing Permits' hourly rate of $225/hour for 'inspections, plan reviews, re-inspections.' RMC 15.46.040(d) separately states 'A re-inspection fee may be charged to the applicant' without naming an amount. 65% · fee schedule (PDF) + ordinance (PDF)
• How are corrections issued and cleared? A written correction notice detailing all deficiencies in the application, plus any additional information/documentation required, is sent to the applicant for resubmission. 85% · ordinance (PDF)
