Buying Land in Chaves County, New Mexico

Chaves County runs its own zoning code -- and its own subdivision, flood, and building ordinances

Chaves County is a genuine exception to the pattern of New Mexico counties that leave land use to a comprehensive plan and state default rules. The county maintains its own Zoning Ordinance (posted by the county as Ordinance No. 7, with subsequent revisions) for unincorporated county land, administered by the Chaves County Planning & Zoning Department. On top of that, the county separately maintains a Subdivision Ordinance governing how land here is legally divided, a Flood Damage Prevention Ordinance tied to floodplain mapping, a Building Code Ordinance, and a Manufactured/Mobile Home Placement Permit Ordinance specifically covering manufactured and mobile home siting -- a genuinely fuller local regulatory stack than many of its rural New Mexico neighbors. The Planning & Zoning Department also assigns rural addresses and administers the county's E911 addressing system, which matters practically since a new rural parcel typically needs an assigned address before it can get utilities or emergency services routed correctly.

Before buying, get the specific zoning district for the parcel from the Planning & Zoning Department, and separately confirm which of the companion ordinances above actually apply to your intended use -- a rural residential build, a manufactured home placement, and a land division each trigger a different one of these processes, and treating "zoning is fine" as covering all of them is a common and avoidable mistake. The Flood Damage Prevention Ordinance is worth taking seriously on its own: Chaves County includes low-lying land along the Pecos River and Hondo River drainages near Roswell, and a parcel in a mapped flood-hazard area can face building elevation or floodproofing requirements independent of whatever its zoning district allows. The county also backs that ordinance with an actual flood-control special district that owns and maintains real levees and drainage infrastructure -- see our dedicated flood-zones page for that history and what it means for a specific parcel.

Near Roswell: a separate, joint zoning authority applies instead

Land close to Roswell doesn't fall under the standard county zoning ordinance described above -- it falls under the Roswell-Chaves County Extraterritorial Zoning (ETZ) Authority and its Extraterritorial Planning and Zoning Commission, a joint city-county body that governs county land generally within about two miles of Roswell's city limits. The commission has seven members -- three appointed by the Roswell City Council, three by the Chaves County Commission, and one additional member appointed by the other six -- and holds public hearings monthly to decide permitting and zoning matters inside the ETZ district. If a parcel is anywhere near Roswell, confirm with the county specifically whether it falls inside the ETZ boundary before assuming standard county zoning district rules (or Roswell's own city zoning) apply -- the ETZ is a distinct third jurisdiction from both. The ETZ Authority also actively legislates on its own -- it has taken up matters like recreational cannabis business regulations within the ETZ district in recent years -- so a rule that applies countywide isn't guaranteed to be the one that actually governs a parcel inside the ETZ boundary.

A real, working agricultural and oil-and-gas economy shapes land use here

Chaves County's land isn't generic rural acreage -- a large share of it is active, productive agricultural or energy-producing land, and that context matters for anyone evaluating a specific parcel's use, water demand, or value. The county leads New Mexico in number of dairy cows and in hay production, and its dairy sector alone generates hundreds of millions of dollars in annual cash receipts; it also ranks highly in the state for corn silage and alfalfa production, and its pecan orchards have produced millions of pounds of pecans in recent years. A working dairy here isn't just a zoning question, either -- it's regulated by the state as a groundwater discharger under its own dedicated rule; see our dedicated livestock/dairy page for what that actually requires. At the same time, Chaves County sits within the reach of the Permian Basin's oil and gas activity, with active wells and production contributing meaningfully to the local economy alongside agriculture; land near active or historic oil and gas operations warrants its own due diligence on surface use agreements, existing leases, and mineral-rights severance.
