Read this before you act on anything below. This is my researched starting point for Valencia County, NM, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesValencia County, NM

Zoning & raw-land occupancy
RestrictedValencia County has countywide zoning administered by Planning & Zoning, unlike many rural NM counties with little zoning. The official zoning map at the County Clerk's office governs; conditional uses/variances need a public hearing. source
Dwellings, tiny homes & RVs
RestrictedManufactured/mobile homes must meet state siting standards and a minimum heated area (county code cites 840 sq ft). RV parks have added rules on liquid waste review and no structural additions. Stand-alone tiny home rules outside a park are not confirmed. source
Building permits & codes
RestrictedValencia County Planning & Zoning issues permits and does zoning/flood review for structures 120 sq ft or larger, while the state's Construction Industries and Manufactured Housing Division handles inspections. source
Septic & composting toilets
Generally allowedValencia County has no own wastewater ordinance (only Bernalillo County does in NM), so septic falls under NMED's statewide Liquid Waste Program; simple systems can be owner-installed after a written test. source
Greywater reuse
Generally allowedNo Valencia County-specific greywater ordinance was found; this appears to follow the statewide NMED greywater rule, though a local addition is not fully confirmed. source
Rainwater harvesting
Generally allowedNo county-specific rainwater ordinance was found; this appears to follow the state Office of the State Engineer's general encouragement of residential rainwater harvesting.
Private wells & water rights
RestrictedWell permitting is handled entirely by the state Office of the State Engineer, not the county; no Valencia County ordinance adds further restrictions. source
Living disconnected from utilities
Unclear - verifyNo county ordinance explicitly requiring utility hookups for stand-alone dwellings was found, though RV parks have specific underground utility rules. Whether a fully off-grid stand-alone home is allowed outside a park is not confirmed; ask Planning & Zoning directly. source
