Off-Grid Living in Colfax County, New Mexico

I've been digging into what "off-grid" actually means legally in Colfax County, New Mexico, and the short version is: it depends heavily on exactly where in the county your land sits.

Zoning. Colfax County, per its own published ordinance list, doesn't run a single countywide zoning code. Instead, there's a joint Raton-Colfax County Extraterritorial Zoning district covering land near the City of Raton, and the county's Subdivision of Land Ordinance (No. 2021-02) and Rural (E-911) Addressing Ordinance govern the rest. Outside the Raton extraterritorial area and incorporated towns (Raton, Angel Fire, Cimarron, Eagle Nest, Springer, Maxwell), most unincorporated land is effectively unzoned. That's good news for flexibility, but it means you should still check with the county whether your specific parcel falls inside that extraterritorial zone before assuming anything.

Dwellings, tiny homes, RVs. I couldn't find a county ordinance specifically addressing tiny homes or long-term RV living. That leaves you defaulting to state minimum construction rules for manufactured/modular housing, or, if you're inside a town like Angel Fire, that town's own building process (which does address setbacks and inspections). For unincorporated county land, this is genuinely unconfirmed, so call the county directly.

Building permits. Where the county hasn't adopted local enforcement, the state's Construction Industries Division (CID) steps in to issue building and trade permits. Inside towns, the town runs its own permitting, generally built on the 2015 NM and International Building Codes.

Septic and greywater. No distinct county septic ordinance turned up, so this runs through the New Mexico Environment Department's statewide liquid waste program, including a septic permit. Greywater reuse follows the state's small-system greywater rule by default, since I found no county-specific rule.

Rainwater. Nothing in Colfax County ordinances restricts residential rooftop rainwater harvesting, and the state Office of the State Engineer's general policy actually encourages it.

Wells and water rights. No county rule here either. Wells fall under the statewide OSE permitting system, and you'd want to confirm which OSE district office covers Colfax County specifically.

Utility disconnection. I found no countywide mandate that you connect to utilities. Any such requirement would more likely come from a municipal code or a subdivision's private covenants, so check both if you're buying in a platted subdivision.

Bottom line: Colfax County leaves a lot of latitude for off-grid living in its unincorporated areas, precisely because it hasn't built out a lot of local ordinance infrastructure. But that also means fewer written answers, more phone calls to the county, CID, NMED, and OSE before you break ground.
