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.
