New Mexico · Off-grid & homestead potential
San Juan County scores 48/100 on the Bolthole Index, a solid county profile. Its strengths are manageable long-term carry cost and deep seclusion — about 55 people within a 30-minute drive. The trade-offs: weak self-sufficiency basics: only 8.9″ of rain a year, in severe drought 50.7% of years and a weaker property-autonomy legal backdrop.

What it takes to build here — permits, zoning, and septic — scouted from San Juan County’s own official sources.
San Juan County has its own Building Department that requires and issues building permits for residential construction in unincorporated areas; permits will not issue without a verified E-911 physical address.
San Juan County Building Department ↗San Juan County has no comprehensive countywide zoning for unincorporated areas; only limited land-use ordinances exist (e.g., manufactured home parks, Farmington extraterritorial zoning), and a proposed countywide land-use ordinance (LUDMO) has faced opposition.
San Juan County Ordinances ↗Septic/liquid waste permits for all land in the county are issued by the state NM Environment Department; the county requires a minimum 0.75 acres per system.
NM Environment Department - Apply for a Septic Permit ↗If the home is the owner's principal residence, a homeowner's permit may be obtained to construct or alter the residence without a contractor's license (permit still required, applied for in person).

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Mexico’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Nearly all developed New Mexico lies inside an OSE 'declared' underground water basin, but a household 72-12-1.1 domestic well is a by-right permit the State Engineer issues even in closed/over-appropriated basins (metering can be required). The by-right amount is cut to 0.25 acre-ft/yr in a declared Domestic Well Management Area, and a few basin-specific orders cap it further (Gallup Order 197, Zuni Order 199) or stop issuing new domestic permits entirely (Hot Springs Order 198).
Limit: 1 acre-ft/yr by right (NMSA 72-12-1.1); 0.25 acre-ft/yr in a declared Domestic Well Management Area
NM OSE domestic well rules, 19.27.5 NMAC ↗OSE-declared Article-7 groundwater basin; new non-domestic (72-12-3) appropriations require an OSE permit showing unappropriated water. The 72-12-1.1 household domestic well remains by-right — no Domestic Well Management Area is declared in New Mexico.
