City of Montague

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 62% · code of ordinances
• What does this authority permit itself, and what does it delegate? Both 52% · county department page
• Is a permit required for a residential rooftop PV system? Yes 80% · county department page
• Is there a separate electrical permit, or is it combined? Combined 58% · county department page
• Is a HOA or architectural approval required first? No 68% · code of ordinances
• Is there a historic-district review? No 68% · municipal code full-text search
• Is a wind or windstorm certification required? No 55% · county department page
• Is a Specific Use Permit or Council approval ever required? No -- not required for a by-right residential rooftop PV system. 65% · municipal code full-text search (absence, control-tested)

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 75% · county department page
• Must the contractor be registered with this authority before applying? No 55% · county department page
• Is a homeowner permitted to self-install and self-permit? Yes 82% · county 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? Building Permit Application, Owner-Builder form (if applicable), property owner's packet, plus for PV specifically: a cover sheet (owner name/address, scope of work, APN, module/inverter make & count, main service size, back-feed breaker size, contractor license #), an overall site plan, an enlarged roof- or ground-mount plan, construction plans (roof framing or foundation plan), an electrical single-line diagram, PV equipment manufacturer cut sheets, structural calculations by a licensed CA design professional, and Title 24 CF1R/CF2R/CF3R energy-compliance forms registered in a CEC-approved registry (CalCERTS/CHEERS). 88% · county solar bulletin (PDF, extracted with pdftotext)
• How many copies, and in what format? Two copies of plans, submitted at 11"x17" preferred (larger sheets accepted if readable); no online portal exists so submittal is by mail, email, or in person. 80% · county solar bulletin (PDF, extracted with pdftotext)
• Is a site plan required, and what must it show? Yes. The overall site plan must show property boundaries, all structures, north arrow, the PV installation location, driveway access, underground trenching (with depths/conduit locations), and the location of electrical service, combiner box, inverter, AC & DC disconnects, junction boxes and battery banks. 88% · county solar bulletin (PDF, extracted with pdftotext)
• Is a one-line / three-line diagram required? Yes 90% · county solar bulletin (PDF, extracted with pdftotext)
• Are string and conductor calculations required? Yes 75% · county solar bulletin (PDF, extracted with pdftotext)
• Is a structural PE stamp required, and at what threshold? Yes, for all roof- and ground-mounted PV racking, with no stated minimum size threshold -- a licensed California design professional's structural calculations are required in every case. 72% · county solar bulletin (PDF, extracted with pdftotext)
• Is an electrical PE stamp required, and at what threshold? Not explicitly stated for PV; the general county rule is that electrical calculations/diagrams are not required for residential services of 200 amperes or less, implying an engineer's electrical stamp (as opposed to a licensed electrician's single-line diagram) is only implicated above that service size. 50% · county department page

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 for either Montague or the county Building Division; the county's Applications and Permits page states outright 'In the future permits will be available online' (i.e. not yet), and provides only downloadable/fillable PDF forms. Montague's own 'Forms and Permits' page lists only a Job Application, a Community Hall Rental Agreement, and a Burn Permit -- no building-permit portal or forms at all. 85% · county department page
• Can the whole application be completed online? No 90% · county department page
• How is the fee calculated? Valuation 72% · county department page
• Is there a separate plan-check fee? Yes (inferred) 55% · county department page

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? Pacific Power (PacifiCorp) 68% · utility CPUC filing
• Where does the utility sit in the sequence? Parallel 70% · utility interconnection guide (PDF, extracted with pdftotext)

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 NEC (as incorporated into the 2025 California Electrical Code, Title 24 Part 3) 62% · county department page
• Which building code edition is in force? 2025 California Building Code / California Residential Code (Title 24, Parts 2 and 2.5), effective January 1, 2026 62% · county department page
• Which fire code edition is in force? 2025 California Fire Code (Title 24, Part 9) 52% · county department page
• Are there local amendments to any of the above? No local amendments found in Montague's own code 55% · code of ordinances (absence)
• What is the installation judged against? The current California Residential Code / California Electrical Code (Title 24 Parts 2.5 and 3) plus Title 24 Part 6 (Energy Code) Chapter 7 / Appendix JA11 solar-specific qualification requirements 62% · county solar bulletin (PDF, extracted with pdftotext)

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 specific ridge-setback dimension is published; the county bulletin defers to the State Fire Marshal's Office and CalFire standards for roof access and pathways rather than stating a local number. 55% · county solar bulletin (PDF, extracted with pdftotext)

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 NEC 690.12 (rapid shutdown) as incorporated into the 2023 NEC / 2025 California Electrical Code 60% · county department page (inference)

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 -- two distinct layers: (1) the AHJ (county bulletin) requires general safety signage identifying the service disconnecting means and PV system disconnect, mounted at/near the panel door; (2) the utility (Pacific Power) separately requires its own placards at the meter base and AC disconnect switch (see Q42). 80% · county solar bulletin (PDF, extracted with pdftotext)
• Does the authority specify placard wording of its own? No specific wording text is mandated by the county bulletin -- it specifies material/format/mounting only, not exact placard language (contrast Pacific Power, the utility, which DOES mandate exact wording — Q42). 62% · county solar bulletin (PDF, extracted with pdftotext)
• Does it specify letter height, colour or material? Yes -- 'Signage shall be green or red plastic engraved with 1/2" high white letters, permanently mounted on or immediately next to the panel door.' 82% · county solar bulletin (PDF, extracted with pdftotext)
• Is a site plan / facility map placard required, and what must it show? A site plan showing the PV installation location, property boundaries, and the location of all major electrical equipment is required (see Q10); no additional dedicated 'facility map placard' distinct from the plan-set site plan and the NEC 705.10 disconnect directory (incorporated by reference through the adopted CEC) was found. 55% · county solar bulletin (PDF, extracted with pdftotext)
• Does the UTILITY specify placards beyond the AHJ's? Yes, extensively. Pacific Power requires: a sign on the meter base reading 'Parallel Generation On Site'; a sign on the AC disconnect switch reading 'Manual Disconnect for Parallel Generation' (numbered '1 of 3' etc. if multiple disconnects); both signs must have a red background with white engraving; and, if the AC disconnect is located more than 3 feet from the meter (only allowed with prior written Pacific Power permission), a separate director placard is required on the meter base showing the disconnect's precise location, red background/white engraving, map-style layout preferred, lettering at least 1/4" tall (≈25-point Arial), minimum 5"x5" (single disconnect) or 6"x6" (dual disconnect) background, with the design pre-approved by Pacific Power before installation. 92% · utility customer-generation guide (PDF, extracted with pdftotext)
• Where must the labels be placed? Utility-required labels: on the meter base, and on the AC disconnect switch (plus a director placard on the meter base if the disconnect is remote). AHJ-required labels (county bulletin): on or immediately next to the panel door. 85% · utility customer-generation guide (PDF, extracted with pdftotext)

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? 3 feet from the meter base in California (Pacific Power's stated distance requirement); the disconnect may be sited farther away only with Pacific Power's prior written permission plus a director placard on the meter base showing its precise location. 88% · utility customer-generation guide (PDF, extracted with pdftotext)
• Must equipment be on a specific approved list? Yes, indirectly: Pacific Power requires the inverter to be IEEE 1547 and UL 1741 certified, and the county PV bulletin requires Title 24 JA11 compliance, which in turn requires modules/inverters to be on the California Energy Commission's approved equipment lists for the CF1R/CF2R energy-compliance forms to be generated. 65% · utility customer-generation guide (PDF, extracted with pdftotext)
• Is a ground mount treated as a structure? Yes -- treated as a structure requiring its own engineered foundation. 68% · county solar bulletin (PDF, extracted with pdftotext)
• Is a specific mounting system or attachment spacing required? Roof racking attachment points must be spaced 4'-0" on center in both directions for the county's 40 psf design roof-load case (below 5,000 ft elevation); ground-mount systems require engineered footings sized per structural calculations, with no reduction of the required snow load allowed. 65% · county solar bulletin (PDF, extracted with pdftotext)

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 webform) or Phone 68% · county webform
• How much notice is required? Effectively one business day when timed correctly: requests received before 7:00 am are scheduled for that same day IF it is your route's scheduled day; requests received after 7:00 am, or on a non-route day, roll to the next scheduled route day. 72% · county webform
• Are same-day or AM/PM windows offered? Yes -- the online request form lets the applicant select a Preferred Period of AM or PM, though the county states this preference 'is only a courtesy and not a guarantee.' 85% · county webform

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? Unclear / possibly Delegated 48% · county webform (ambiguous)
• If delegated, to whom? If delegated: Siskiyou County Community Development, Division of Building and Safety (806 South Main St., Yreka; Deputy Director Glenn Shockency, 530-841-2100) -- not confirmed as the operative delegate, see Q52. 48% · county contact page (inference)

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? General sequence per the county's Required Inspections page (not solar-specific): Foundation → Concrete Slab/Underfloor → Framing (incl. Electrical rough) → Insulation → Lath/Wallboard → Final. For a PV retrofit on an existing home this compresses to Electrical Rough (if applicable) → Building/Electrical Final, per the categories on the county's Building Inspection Online Request Form. 58% · county department page

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 (general, not solar-specific) 62% · county department page
• What must be on site at inspection? The permit card (which shows the assigned inspection route/day), approved plans, and -- per Title 24 -- the PV installer's signed Certificate of Installation (CF2R), which 'shall be available on the building site for inspections' per JA11.7. 72% · county solar bulletin (PDF, extracted with pdftotext)

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 'Building Final Inspection' category — covering Building, Electrical, Plumbing, Mechanical, Energy, Grading, and Occupancy — exists on the county's inspection request form); CO/Green-tag/Letter terminology is not otherwise used in the published materials for a residential PV retrofit. 58% · county webform
• Who notifies the utility for PTO? Installer (in practice), per Pacific Power's own process 58% · utility interconnection guide (PDF, extracted with pdftotext)
