Lassen County, CA · off-grid fact sheet

Can you live off-grid in Lassen County, California?

81
of 100
Good with caveats

Yes, but water will be the challenge. Only about 19 inches of rain falls a year, so you will rely on a well (near 200 feet here) or hauled water. The sun is strong, about 6.0 hours of full sun a day, so a smaller solar array covers a household. The growing season is only about 100 frost-free days, so plan on cold-hardy crops and a greenhouse.

Is it legal here?

Zoning
We found no public zoning map for Lassen County, so call the county planning office with the parcel number to ask whether the land is zoned.
Building code
The California Building Standards Code (Title 24) applies statewide and every city and county must enforce it, so a new house needs a permit however remote. A county may adopt the state's optional rules for owner-built rural homes, which relax some standards but still require a permit.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed with a permit and an approved unit.
Water rights
A mix of two systems. Ask the state water office before you drill a well or dam a creek.
