Siskiyou County

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, for the unincorporated area of the county only 90% · authority's own page
• What does this authority permit itself, and what does it delegate? Both 90% · department page
• Is a permit required for a residential rooftop PV system? Yes 85% · department page / ordinance reference
• Is there a separate electrical permit, or is it combined? Combined 65% · department page
• Is a HOA or architectural approval required first? No -- the county does not require HOA/architectural approval as a permit prerequisite 55% · department page (absence checked) + state law context
• Is there a historic-district review? Conditionally -- only if the property sits within a locally-designated design review or preservation district, or is a historic landmark 70% · department page
• Is a wind or windstorm certification required? No 60% · department page
• Is a Specific Use Permit or Council approval ever required? Not required for a typical residential rooftop PV system; a Use Permit could be triggered for a large ground-mount array or a property in a restrictive zoning district under Title 10, but no solar-specific Use Permit trigger was found 55% · department page + site search

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 (licensed electrical/solar contractor, or the homeowner as owner-builder) 55% · inference from department forms
• 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 85% · department forms

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? Plot plan with elevations (true north indicated), floor plan, foundation plan, structural plan with engineering calcs, electrical plan/specs, plumbing plan/specs, energy compliance forms; for solar specifically, engineered solar system design drawings tied to Title 24 energy compliance calcs, roof-mount location per plan set or ground-mount with concrete footing calculations 75% · department guideline PDF + program page
• How many copies, and in what format? 2 identical hardcopy sets for residential projects (3 for commercial), black or blue line, minimum 18"x24" sheet size, drawn to scale 75% · archived department page
• Is a site plan required, and what must it show? Yes - a plot plan with elevations showing true north (18 degrees west of magnetic north unless depicted otherwise); for solar, the site plan must show roof-mounted location per the pre-approved plan set, or a ground-mount system with concrete footing calculations 78% · department page
• Is a structural PE stamp required, and at what threshold? Not solar-specific, but the county's general plan-and-specifications table requires ALL residential and residential-accessory structural plans to be prepared, signed and stamped by a California-licensed architect or engineer, with no size/valuation threshold exemption stated 60% · department guideline PDF

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? Siskiyou County Public Portal, powered by SmartGov (Granicus), at co-siskiyou-ca.smartgovcommunity.com 90% · portal landing page
• Can the whole application be completed online? No -- application and status tracking can be done online, but hardcopy plan sets (2 for residential) must still be mailed/delivered to the Building Division before review begins, and the county's own Applications and Permits page (fetched live today) still says 'In the future permits will be available online' 75% · department page
• How is the fee calculated? Valuation 80% · fee schedule page
• Is there a separate plan-check fee? Likely yes, as a percentage of the permit fee 55% · inference from cited model code

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? 8 to 10 weeks average for a complete plan submittal (as of the 2025 code-cycle implementation surge); separately, the new online portal states a 5-business-day turnaround just for an initial response from staff 80% · department page
• Which utility handles interconnection here? Pacific Power (PacifiCorp) 78% · utility filing / CEQA record
• Where does the utility sit in the sequence? Parallel, with a hard dependency at the end: the customer generation application/approval with Pacific Power can proceed independent of the county permit, but Pacific Power will not energize (install the net meter) until the installer submits the county's approved electrical inspection to Pacific Power 80% · utility interconnection guide

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 (adopted as the 2025 California Electrical Code, Title 24 Part 3), effective 1 January 2026 85% · authority's own page
• Which building code edition is in force? 2025 California Building Code and 2025 California Residential Code (Title 24 Parts 2 and 2.5), effective 1 January 2026 95% · authority's own page
• Which fire code edition is in force? 2025 California Fire Code (Title 24, Part 9), effective 1 January 2026 95% · authority's own page
• Are there local amendments to any of the above? Yes -- local design-value amendments exist for wind speed and ground/roof snow load (a countywide basic wind speed of 95 mph V plus area-specific snow load minimums of 60 psf for McCloud, Mt. Shasta, Weed, Happy Camp and Dunsmuir vs 40 psf elsewhere, now cross-checked against the ASCE 7 Hazard Tool for the 2025 cycle) 80% · authority's own page
• What is the installation judged against? The adopted 2025 CBC/CRC/CEC/CFC/Green Code (effective 1/1/2026) plus the county's own wind-speed and snow-load design amendments 78% · authority's own page

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 Siskiyou-specific ridge-setback/pathway rule was found beyond whatever the adopted 2025 California Fire Code and California Residential Code impose by reference (fire-code roof access pathway and ridge-setback provisions such as those in CFC Ch.12 / CRC R324) 50% · inference from adopted code edition

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, rapid shutdown is required under NEC 690.12 as incorporated in the adopted 2025 California Electrical Code (based on the 2023 NEC) 75% · inference from adopted code edition

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? No Siskiyou-specific placard list was published; the only placard requirement documented is Pacific Power's own requirement that the AC/battery disconnect switch carry a placard (plus, by default, whatever the adopted NEC 690/705 series requires at the service equipment) 65% · utility spec
• Does the authority specify placard wording of its own? No 60% · department page (absence checked)
• Does it specify letter height, colour or material? No -- the county does not publish its own letter-height, colour or material spec; only the utility's disconnect-placard note (battery location and shutdown-indicator wording) and whatever the adopted NEC 690/705 series specifies apply 55% · department page (absence checked)
• Is a site plan / facility map placard required, and what must it show? A rapid-shutdown/facility map placard is required as a function of the adopted NEC (705.10 / 690.56(C)) rather than any county-specific bulletin; no Siskiyou-specific facility-map spec was found 60% · inference from adopted code edition
• Does the UTILITY specify placards beyond the AHJ's? Yes -- Pacific Power requires its own placard at the battery/solar disconnect switch stating the battery's physical location and how field personnel can visually confirm it is shut down (e.g. LED/halo indicator), in addition to whatever the AHJ requires 90% · utility DG spec
• Where must the labels be placed? At the service equipment / next to the utility meter -- Pacific Power's spec places the solar disconnect switch and its placard next to the utility meter, and the AC disconnect must be located between the production meter and the sub-panel per Pacific Power's general interconnection requirements 75% · utility spec

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 3 feet of the meter in California (per Pacific Power's stated state-specific distance requirement -- Oregon uses 10 feet), lockable in the open position, with a visible open/closed indication, located between the production meter and the sub-panel 90% · utility DG spec
• Must equipment be on a specific approved list? No county-specific approved-equipment list was found; standard UL-listing / NEC compliance applies by default through the adopted electrical code 55% · inference from adopted code edition
• Are batteries permitted, and under what conditions? Presumably permitted subject to the adopted 2025 California Fire Code's energy-storage-system provisions; no Siskiyou-specific battery/ESS restriction, size cap or siting rule was found 50% · inference from adopted code edition
• Is a ground mount treated as a structure? Yes 75% · department page
• Is a specific mounting system or attachment spacing required? No county-specific mounting-system or attachment-spacing standard was found; roof-mount or ground-mount systems must simply be engineered per site-specific structural calcs (with concrete footing calculations required for ground-mount), per the general design/engineering requirement rather than a prescriptive spacing table 55% · department page

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 90% · department page
• How much notice is required? Effectively next business day, or same day if the request is submitted online before 7:00 AM on that route's inspection day 80% · department webform page
• Are same-day or AM/PM windows offered? AM/PM preference can be selected on the request form, but it is described as 'a courtesy and not a guarantee'; same-day service is available if the request is submitted before 7:00 AM on the applicable route day 82% · department webform 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 85% · department page
• If delegated, to whom? Not applicable -- inspections are not delegated; the county performs them itself 85% · 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? General sequence published is Foundation, Concrete Slab/Underfloor, Framing (includes electrical rough-in), Insulation, Lath/Wallboard, Final; a solar-only retrofit would typically use only the Framing/rough-electrical and Final steps from this list, though the county does not publish a solar-specific subset 70% · department page
• Is a rough-in or mid-roof inspection required? No distinct mid-roof inspection is listed; the general 'Framing' inspection stage explicitly includes an electrical check, which is where a rooftop PV rough-in would likely be caught 60% · 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? No -- only a general, non-solar-specific 'guideline' list of inspection stages is published; the page itself says the list 'may or may not be all inclusive' 65% · department page (absence checked)

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 65% · department page
• Who notifies the utility for PTO? Installer 85% · utility DG manual
