Off-Grid Living in Taos County, New Mexico

I've been digging into what it actually takes to live off-grid in Taos County, New Mexico, and the short version is: unincorporated Taos County is not a "no rules" frontier, but it's also not as buttoned-up as, say, a suburban subdivision back east. Here's what I found, level by level.

Zoning. Taos County adopted comprehensive land use regulations (the county's 2018-2 Land Use Regulations, building on earlier 2003-era ordinances), so raw land here is zoned and a Residential Zoning Clearance Permit is generally the starting point. If your parcel has slopes over 20%, expect the county to bump you up to an Administrative Permit or Special Use Permit process instead of the basic clearance. Some older neighborhoods (Upper Las Colonias, Stagecoach, etc.) layer their own sub-zone rules on top, so it's worth asking Planning specifically about your parcel.

Dwellings, tiny homes, RVs. I could not find a Taos County-specific ordinance addressing tiny houses or full-time RV living. The Town of Taos (a separate home-rule municipality) has its own manufactured-home rules, but that's a town matter, not a county one. If this is part of your plan, call County Planning directly before you buy land or build.

Building permits. The county requires permits and enforces state-adopted codes, including the 2021 NM Energy Conservation Code for energy calculations. You can self-perform work under a Homeowner's Permit, but that puts you on the hook for code compliance. Electrical, plumbing, and mechanical work gets routed to the state's Construction Industries Division rather than handled purely at the county level.

Septic and composting toilets. There's no separate county wastewater ordinance I found; the county defers to the New Mexico Environment Department. You need an approved NMED Liquid Waste Permit before the county signs off on a new home, and simple conventional systems can sometimes be self-installed after passing NMED's written test.

Greywater and rainwater. I didn't find any Taos County-specific rules narrowing or expanding on state policy for either. Both appear to run under New Mexico's statewide framework, so plan on state rules applying unless Planning tells you otherwise.

Wells and water rights. Taos County does not issue well permits, full stop, that's the New Mexico Office of the State Engineer's job. The county still wants proof of legal water (a well permit or a water/sanitation district letter) as part of your zoning clearance packet.

Off-grid utilities. This one's genuinely murky. I didn't find a countywide law mandating a utility hookup, but the zoning clearance packet does require a sign-off from Kit Carson Electric Cooperative regardless of the project. Whether that's a real barrier to going fully off-grid or just paperwork, I can't say for certain, ask Planning directly.

Bottom line: confirm everything with the named county and state offices below before you commit to land or a build plan, since layered zones and slope rules can change your path fast.
