Off-Grid Living in De Baca County, New Mexico

I'll be upfront: De Baca County, New Mexico is one of the harder places for me to research because I can't find an official county government website with a real planning, zoning, or building department page. What comes up instead is a volunteer genealogy site, not a .gov portal. So a lot of what follows is "here's the New Mexico state baseline, and here's what's not confirmed at the county level."

Zoning. New Mexico's Zoning Enabling Act lets counties adopt zoning if they choose to, but I could not confirm whether De Baca County has an actual countywide zoning ordinance on the books. Given how rural and sparsely populated the county is, it may operate with little or no comprehensive zoning, but that's a general characterization, not something I can point to an ordinance for. Fort Sumner, the only incorporated town in the county, might have its own zoning code as a municipality, but I couldn't locate an official Fort Sumner zoning page either. If you're eyeing land here, call the county courthouse and ask directly.

Dwellings, tiny homes, RVs. No county or Fort Sumner ordinance on tiny home or RV occupancy turned up in my research. The state's Construction Industries Division (CID) sets minimum standards for manufactured and modular homes, but day-to-day occupancy rules for RVs and tiny houses are typically a local call, and I found no local determination for De Baca County.

Building permits. Same story: no county building permit page or locally adopted code found. Statewide, CID (a state agency) writes and administers the Construction Industry Division rules, and in counties without their own certified building department, CID's field offices often issue permits directly. Whether that's how it works in De Baca County specifically is not confirmed, so ask CID or the county courthouse.

Septic and composting toilets. This one I can say with more confidence: septic systems in De Baca County fall under the state's New Mexico Environment Department (NMED) liquid waste program, not a county ordinance. Bernalillo County is the only county in the state with its own onsite wastewater program, so De Baca defaults to NMED. Homeowners can even self-install a conventional system after passing a homeowner qualification exam through their local NMED field office.

Greywater. Also state-regulated. NMED's statewide greywater rule allows small residential systems without a permit if you meet the design criteria; I found no county-level deviation.

Rainwater harvesting. Generally allowed under the state's Office of the State Engineer framework for on-site domestic and irrigation use, with no county rule found that changes that.

Wells and water rights. Fully state-administered by the Office of the State Engineer under prior appropriation, since there's no county water authority outside Fort Sumner. Rural water here typically comes from independent water associations, not county government.

Utility disconnection. I found no county or state mandate forcing you to connect to a grid utility. Any such requirement would come from a subdivision covenant or deed restriction, not something confirmed at the county level here.

Bottom line: De Baca County is thin on published local rules, so state agencies (NMED, OSE, CID) end up doing most of the regulating by default. Call the county courthouse first for anything zoning or building related.
