Whether a new home can legally get its own water here — the sub-state groundwater regime, from California’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
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
California DWR / State Water Board — SGMA de minimis & EO N-7-22 Action 9 FAQ ↗Adopted GSP with pumping limits to 2040 (seawater intrusion); new production wells subject to GSA consistency review and EO N-7-22; de minimis domestic wells still need a county permit.
California DWR Bulletin 118 — Critically Overdrafted Basins ↗Managed via an approved GSP-Alternative with basin-wide extraction fees; new wells subject to county permit + EO N-7-22/GSA review.
