California · Off-grid & homestead potential
Lake County scores 49/100 on the Bolthole Index, a solid county profile. Its strengths are deep seclusion — about 641 people within a 30-minute drive and manageable long-term carry cost. The trade-offs: elevated mid-century heat, water, rain, or wildfire exposure and more administrative friction around building and land use.

California requires no STATE permit for a domestic well — wells are permitted by the county — but under SGMA a Groundwater Sustainability Agency can meter or restrict new wells in medium/high-priority and critically overdrafted basins, and Executive Order N-7-22 requires counties in those basins to get GSA verification that a new well is consistent with the Groundwater Sustainability Plan before permitting.
