California · Off-grid & homestead potential
Humboldt County scores 61/100 on the Bolthole Index, a solid county profile. Its strengths are deep seclusion — about 1 people within a 30-minute drive and manageable long-term carry cost. The trade-offs: elevated current hazard exposure and more administrative friction around building and land use.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from California’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
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.
Limit: 2 acre-feet/year de minimis under SGMA (Water Code §10721(e)) — largely exempt from GSA metering/fees
