Off-Grid Living in Otero County, New Mexico

I've spent a while digging through Otero County's official pages, and the headline here is unusual for New Mexico: the county government says flat-out that it has no zoning or licensing requirements countywide. That's a real thing, straight from the county's own Zoning page, not a loophole I'm reading into. But "no zoning" doesn't mean "no rules at all," so let me walk through what I actually found.

Zoning and raw land. Otero County confirms it has no countywide zoning or licensing. The Planning Commission's job is limited to reviewing subdivisions (lot layout, roads, that kind of thing), not general land use. That said, deed restrictions, covenants recorded on a specific parcel, or extra-territorial jurisdiction (ETJ) review near incorporated towns can still limit what you do. And remember, Alamogordo, the county seat, is its own incorporated city with its own planning and code enforcement, so none of this "no zoning" talk applies once you're inside city limits.

Dwellings, tiny homes, RVs. I could not find a county ordinance addressing tiny homes or full-time RV living specifically. Since there's no county zoning, the practical floor is whatever the state Construction Industries Division applies through manufactured housing rules. I'd call this genuinely unclear and worth confirming directly before you buy land expecting free rein.

Building permits. Otero County doesn't run its own building department for the unincorporated county. Instead, the county's own site directs you to the State of New Mexico Regulation and Licensing Department, Construction Industries Division (CID) and Manufactured Housing Division (MHD). That's a state-level permit process, not a county one, so plan on dealing with the state's Las Cruces office.

Septic and composting toilets. Septic systems follow the statewide NMED Liquid Waste Program. The county points residents to NMED's District III office in Alamogordo. Under the state rule, homeowners can install simple conventional systems themselves after passing a written test, or hire a licensed installer.

Greywater and rainwater. I didn't find any Otero County-specific ordinance on either. Both default to state rules: NMED's small residential greywater regulation, and the state's general encouragement (via the Office of the State Engineer) of rainwater harvesting.

Wells and water rights. New Mexico runs a prior-appropriation water rights system statewide through the Office of the State Engineer, and that's what governs well permits here too. OSE keeps an Otero County-specific subdivision review page, but I didn't find any additional county well ordinance layered on top.

Utility disconnection. No countywide rule forces you to hook up to utilities. The county's Subdivision Ordinance does penalize utility companies that connect service to un-platted or unpermitted parcels within a subdivision, but that's aimed at the utility/subdivision process, not a mandate on homeowners.

Bottom line: Otero County is refreshingly light-touch on paper, but nearly everything meaningful (building, septic, wells) is handled by state agencies, not the county, so you'll be dealing with Santa Fe and Las Cruces offices more than the county courthouse.
