Catron County, NM Building Permits, Zoning & Septic Rules

Catron County, New Mexico generally requires state building permits for residential construction; the New Mexico Construction Industries Division issues the permits and performs inspections because the county has no local building department¹. The county's published materials do not conclusively answer whether zoning applies, so confirm parcel-specific use, setback and RV questions with the county before buying². The New Mexico Environment Department handles septic permits and inspections³⁴.

Do you need a building permit in Catron County, New Mexico?

Yes. Construction-related work in Catron County needs a permit when New Mexico statute or rule requires one⁵. The New Mexico Construction Industries Division, rather than a county building department, issues residential permits and performs inspections in Catron County¹. Residential work under CID jurisdiction follows the adopted New Mexico Residential Building Code, with other adopted codes applying according to the project and trade¹⁴. State rules exempt some minor work, including a one-story detached accessory building no larger than 120 square feet and a fence no higher than 6 feet⁶. Separate electrical, plumbing or mechanical permits may still be required for otherwise exempt work⁶. Permit fees vary with construction type, square footage, materials and cost¹⁵.

Who handles Catron County building permits and inspections?

The New Mexico Construction Industries Division handles state building permits and inspections for Catron County because the county has no local building department¹. Applications can be completed through the state's online permitting portal¹⁶. Required residential inspections include foundation, slab or under-floor, frame, weather-resistive barrier and final stages; final electrical, plumbing and mechanical inspections precede the final general-construction inspection⁶. Request an inspection from CID using the contact information above¹⁷. An owner-builder permit is limited to the owner's primary residence, and the owner must complete the major portion of the work measured by dollar value¹⁰. The owner-builder application also requires proof of ownership, zoning approval, a floodplain determination, identity documents, a notarized responsibility sheet and applicable fees¹⁰.

Does Catron County, New Mexico have zoning?

Catron County's published ordinance list contains no zoning ordinance, but the official material does not expressly say that countywide zoning is absent². Treat zoning as unresolved rather than assuming a parcel is unrestricted. New Mexico law allows counties to zone land outside municipal zoning jurisdiction, so municipal boundaries and the parcel's exact location matter¹⁸. We could not confirm countywide rules for minimum lot size, setbacks, building height, lot coverage, accessory dwellings or minimum house size. Ask Catron County to confirm those points in writing for the parcel before ordering plans. Land division is a separate issue: county commissions regulate subdivisions under the New Mexico Subdivision Act even when a zoning answer is unclear¹⁹.

How do septic permits work in Catron County?

The New Mexico Environment Department, not Catron County, administers on-site liquid-waste permits here³. Obtain the NMED permit before installing a new system or modifying an existing one⁸. The application package includes proof of ownership, a floor plan and a site diagram showing structures, wells, boundaries, systems and setbacks⁸. Submit the complete package to the local NMED field office, then pay only after NMED says the permit is approved or approved with conditions²⁰²¹. Published fees vary by system type and design flow²². Request inspection 48 hours, or 2 business days, in advance and leave the system uncovered; an approved inspection leads to the Permit to Operate⁴. Only 22.6% of Catron County soils are rated without severe limits for a conventional drain field, so establish septic feasibility early¹³.

Can you live in an RV or tiny home in Catron County?

We could not confirm a Catron County rule allowing long-term RV residence or temporary camping on private land. Ask the county about occupancy, sanitation and parcel-specific land-use limits before treating an RV as a lawful dwelling. A tiny house on a permanent foundation can qualify under New Mexico's residential code when it provides complete living facilities and complies with the state's tiny-house appendix; the definition generally limits floor area to 400 square feet excluding lofts¹². A tiny house that keeps its permanent axle is treated as an RV instead, so the permanent-foundation rule does not establish a right to live in a wheeled unit on any parcel¹². Off-grid sanitation also remains regulated: untreated liquid waste generally must enter an approved system, while qualifying residential graywater has narrow conditions²³.

What are the steps to build a home in Catron County?

Confirm with Catron County whether parcel-specific zoning, setbacks, floodplain review or access requirements apply; the published county material does not settle those questions².

Establish septic feasibility and submit ownership proof, a floor plan, a site diagram and the other required documents to the local NMED field office⁸²⁰.

Wait for NMED approval before paying the septic fee, then arrange inspection before the system is covered²¹.

Apply to CID for the required state building permit with plans and the applicable fee²⁴¹⁵.

Schedule CID inspections as construction reaches the foundation, under-floor or slab, frame, weather-barrier and final stages⁶¹⁷.

If the driveway connects directly to a state highway, obtain the New Mexico Department of Transportation access permit before constructing or modifying that access²⁵.

What should you check before buying land in Catron County?

Check water and septic feasibility before closing: Catron County averages about 15.3 inches of precipitation a year, severe drought occurs in about 38.3% of years, and only 22.6% of soils are rated without severe limits for a conventional drain field²⁶²⁷¹³. We could not confirm the private-well permit rule, so ask the New Mexico Office of the State Engineer what a proposed well requires. Verify legal access and road maintenance, and obtain a state access permit if the driveway will meet a state highway²⁵. Check flood maps and ask the local floodplain administrator whether development approval applies in a Special Flood Hazard Area²⁸. About 63.1% of the county is federal land, making boundary and access review especially important²⁹. The effective property-tax rate is about 0.3%, and the median annual property-tax bill is about $583³⁰³¹.

Watch-outs

Do not assume that the lack of a clearly identified zoning ordinance makes a Catron County parcel unrestricted; ask the county to confirm uses, setbacks and occupancy rules for the exact parcel².
Only 22.6% of Catron County soils are rated without severe limits for a conventional septic drain field, so confirm septic feasibility before buying¹³.
A small structure can be exempt from a building permit while still needing separate electrical, plumbing or mechanical permits³².

Water rights & wells in Catron County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Mexico’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellPermit required (issued by right)

Nearly all developed New Mexico lies inside an OSE 'declared' underground water basin, but a household 72-12-1.1 domestic well is a by-right permit the State Engineer issues even in closed/over-appropriated basins (metering can be required). The by-right amount is cut to 0.25 acre-ft/yr in a declared Domestic Well Management Area, and a few basin-specific orders cap it further (Gallup Order 197, Zuni Order 199) or stop issuing new domestic permits entirely (Hot Springs Order 198).

Limit: 1 acre-ft/yr by right (NMSA 72-12-1.1); 0.25 acre-ft/yr in a declared Domestic Well Management Area

State Engineer Order 199 (2023) closes this area to new non-domestic appropriations and caps a household domestic well at 0.50 acre-ft/yr with a mandatory meter; relevant to off-grid buyers near the lake in southern Catron County.

Gila-San Francisco Underground Water Basinpartial of county
OSE-declared Article-7 groundwater basin; new non-domestic (72-12-3) appropriations require an OSE permit showing unappropriated water. The 72-12-1.1 household domestic well remains by-right — no Domestic Well Management Area is declared in New Mexico. Gila/San Francisco drainages; appropriation and transfer are tightly constrained by the Gila adjudication and the federal Arizona Water Settlements Act.
