Off-Grid Living in Siskiyou County, California
Siskiyou County allows off-grid-style living but only through its standard permitting system - zoning approval, a building permit, an approved septic method, and a well permit if you're not on public water. There's no dedicated "off-grid" exemption anywhere in county code, so confirm specifics with Planning, Building, and Environmental Health before you buy land or build.

I've spent a good chunk of time digging through Siskiyou County's own code and department pages to figure out what off-grid living actually looks like here, and the short version is: it's doable, but it runs through permits, not around them.
Zoning first. Siskiyou County uses countywide zoning administered by the Planning Division, and the ordinance is what's called "permissive" - meaning if a use isn't specifically listed as allowed in your zone, it's not allowed, full stop. That includes just parking yourself on raw land and living off-grid without an approved dwelling or use. Your parcel's actual zoning is on file as "Sectional District Maps" with Planning, so that's your first call before buying land.
Dwellings and RVs. The Building Division will let you get a camping/RV permit as temporary housing while you build a permitted site-built home, but that trailer has to come off the property once your house passes final inspection. I did not find a clear county policy on park-model tiny homes as permanent residences, so if that's your plan, call Building directly and ask.
Building permits go through a standard multi-agency review: Planning checks your plot plan against zoning and setbacks, and Cal Fire has to sign off on new dwellings for fire-safety access before you can build.
Septic. The county's Environmental Health Division (part of Community Development) runs the onsite sewage program. Standard septic systems are the expected route, and I want to be honest that composting-style vault privies are only permitted "under certain circumstances as deemed appropriate" by the Public Health officer, so that's a case-by-case ask, not a guaranteed yes.
Greywater - I couldn't find a Siskiyou-specific ordinance on this. My read is the county defaults to the state Plumbing Code baseline, but confirm with Environmental Health before you build a system.
Rainwater harvesting looks fine from what I found; there's no county rule against rooftop collection, and Environmental Health even has a water storage guidance document. Just note that's separate from groundwater, which the county manages under its own local ordinance tied to correlative water rights.
Wells need a county permit through Environmental Health, and there's an added wrinkle: California's 2022 statewide drought executive order added new permitting requirements, and Siskiyou County adopted procedures to match. Well records before 1991 sit with the state Department of Water Resources, not the county.
Bottom line on utilities: there's no standalone "off-grid ordinance" here, but you can't skip the underlying requirements. Any permanent dwelling still needs a building permit, an approved sewage method, and a well permit if you're not on a public system. Going off-grid doesn't exempt you from any of it.

Planning a build in Siskiyou County
The rules above decide what you may build. The numbers below decide what you will have to build, and they come from this place rather than from a national average.
Solar: size for the worst month, not the average
Siskiyou County averages 6.1 peak sun hours a day across the year, but its worst month averages 3.5. That is a drop of about 42 percent. An array sized on the annual figure will therefore come up short in the worst month by roughly that much, in the season when lights, pumps, and heating fans all run hardest.
Put another way, meeting the same daily load in the worst month here takes about 1.7 times the array that the annual average implies, or a generator and the fuel budget to run it. Neither is wrong; what is wrong is discovering the gap in the first winter. The solar calculator runs this arithmetic against your own load list, and lesson four covers building that list before buying panels.
Heat: 2,314 heating degree days
That is a moderate heating season, where a single well-chosen appliance usually carries the house. Heating demand at this level dwarfs everything electrical in the house, which is why almost nobody here heats with electricity from a battery bank.
As a rough order of magnitude, a small, reasonably insulated cabin heated mainly with wood in a climate like this tends to burn in the region of 1.9 cords a season, with the real figure swinging widely on insulation, house size, and how you burn. Treat that as a bracket for planning your woodshed rather than a promise, split and stack a season ahead, and check with a moisture meter before burning. The firewood calculator and heat-loss calculator narrow it down from your own building.
Water: what the roof would actually catch
Siskiyou County receives about 8.4 inches of precipitation a year. A 1,000 square foot roof here would shed on the order of 4,448 gallons a year at a realistic 85 percent collection efficiency, before any losses to first-flush diversion, evaporation, or overflow in a heavy storm.
The annual total is the easy part. What sizes a cistern is the longest dry stretch, because catchment is seasonal almost everywhere and a tank that covers the average year can still run empty in August. Check the local rules too: rainwater harvesting is regulated in some states even where it is broadly allowed. The rainwater calculator works from your own roof and rainfall pattern, and lesson three covers why water is chosen before power.
Distance is part of the plan
Measured straight line from the center of Siskiyou County: the nearest fire station is about 3.5 miles away (Fresno County Fire Department Station #93), the nearest hospital is about 15.8 miles away (Coalinga Regional Medical Center), the nearest supermarket is about 15.2 miles away (A & M Market). Road miles will be longer, and in winter longer again.
The fire distance is worth noting before you buy rather than at renewal: insurers commonly rate rural property partly on how far it is from a responding station and from a water source, and some decline off-grid or owner-built structures outright. Ask an agent who writes rural policies what they would need to see, while the answer can still change what you build. Lesson eleven covers the insurance and financing side.
The hospital distance sets what your first aid kit and your medical plan have to cover in the gap, and it is the number to think about before anyone in the household depends on refrigerated medication or mains-powered equipment.
Confirming this for your own parcel
On this page 1 of the eight topics is recorded as unclear or as varying within Siskiyou County: greywater. Those are the calls to make first, because they are the ones where a general answer cannot be trusted for a specific parcel. Ask for the answer in writing where the office will give it, and note the name and the date where it will not.
Where a topic is recorded as settled here (zoning, what counts as a dwelling, building permits and codes, septic and sewage, rainwater harvesting, wells and water rights, mandatory utility connection), the source is cited further down this page. Sources go stale, ordinances get amended, and this site logs corrections publicly rather than editing them away, so if you find something here that no longer matches the county, the corrections page is how to say so.
Before any of those calls, walk the parcel with the land walk checklist and take the questions for the county with you. The parcel check pulls flood, wetland, slope, and access data for a specific parcel and shows its sources, which is a good way to arrive at the office with the questions already framed. Lesson two is the wider version of this list.

FAQ
Common questions about off-grid living in Siskiyou County
Is it legal to live off-grid in Siskiyou County, California?
There is no outright ban on living off-grid in Siskiyou County, California - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are restricted. Plan around septic/wastewater (restricted) and disconnecting from utilities (restricted). Because these rules are set locally, confirm the specifics with Siskiyou County before you buy land or build.
Can I just buy land in Siskiyou County and live off-grid without permits?
No. County zoning is permissive-only, meaning uses not listed as allowed in your zone aren't permitted, so raw-land occupancy without an approved dwelling or use isn't allowed by the Planning Division.
Can I live in an RV permanently on my own land?
Not as a permanent arrangement per the Building Division; RV/camping permits are meant as temporary housing while you build a permitted site-built home, and the RV must come off the site after final inspection.
Are composting toilets allowed instead of a septic system?
Vault privies may be approved, but only case-by-case at the discretion of the Public Health officer, so check with Environmental Health before counting on this option.
Do I need a permit to collect rainwater?
No county restriction on rooftop rainwater harvesting was found; it appears to be permitted, separate from the county's groundwater management rules.
What about drilling my own well?
You'll need a permit from Siskiyou County Environmental Health, and new wells are also subject to added conditions tied to a 2022 statewide drought executive order that the county incorporated into its permitting process.
