Barndominium Builders in Doña Ana County, New Mexico

Much of the land people buy for a shop house in southern New Mexico lies in unincorporated Doña Ana County: pecan-country tracts along the Rio Grande, mesa acreage toward the Organ Mountains, and desert lots around Chaparral and Anthony. We supply barndominium plans and kit packages for these parcels, and a New Mexico-licensed contractor, or an owner-builder building a primary residence, does the construction. Outside the city limits the county has its own Building Services Division with a certified building official, plan examiners and inspectors, so the house is reviewed locally rather than by the state. The county's single-family checklist is the thing to read early. It wants proof of septic or sewer and proof of water before a permit is issued, a printed site plan that shows an on-lot pond for storm runoff, and truss and energy paperwork with the drawings. If you are sorting through barndominium contractors for land in the county, confirm that each one has worked through that checklist before. Send your parcel through the survey and we will check which of those items your land still needs.

County-issued permitWho issues the permit

Doña Ana County Community Development Department, Building Services Division

For unincorporated land, the county's Building Services Division takes building, electrical, plumbing, mechanical and manufactured home applications, routes them to other county departments, issues the permits and inspects. Las Cruces and Sunland Park run their own permitting inside their limits, so check the parcel's jurisdiction first.

Before a house permit: The county's Single Family Dwelling permit checklist asks for a copy of the septic tank permit from the New Mexico Environment Department or a ready, willing and able letter from a sewer provider, and for a State Engineer well permit or a letter from a water provider. Utility bills are not accepted. A property with more than one dwelling needs a septic permit for each.
Review and inspections: The same checklist describes a 15 business day review once payment is received, with the file routed to the Flood Commission, Planning, Addressing, Utilities, Building Services and Engineering. It lists foundation, sheathing, frame, lath, insulation and final inspections; licensed tradesmen pull the electrical, plumbing and mechanical permits after the building permit issues.
Stormwater and access: The checklist requires a SWPPP and notice of intent for any project in a subdivision, or outside one when the parcel exceeds one acre. A driveway onto a county road needs a county driveway permit, and access onto a state road may need an NMDOT permit.
On-lot ponding: The county's On-Lot Ponding Requirements, drawn from its Unified Development Code, size the pond to hold 125% of the runoff from the property's impervious area, set it at least 5 feet from property lines and 10 feet from structures, require a minimum depth of 18 inches, and require fencing past 3 feet deep. Maintenance falls on the owner.
Energy climate zone: The state's residential energy code (14.7.6 NMAC, Table 301.2) lists Las Cruces in Doña Ana County at 4,000 feet in climate zone 3B, one of the warmest zones the table assigns.

Building on land near Doña Ana County

Parcels near Doña Ana County's valley towns vary more than the map suggests. Irrigated farm ground along the river sits close to the water table, while desert tracts on the mesas depend on a domestic well permitted by the Office of the State Engineer and a septic system permitted by the Environment Department. Because the county wants a pond on the site plan, the roof area of a large shop house directly sets how much ground the pond takes, and that belongs in the layout from day one. Check the road too: a county or state road frontage decides which driveway permit applies. Splitting a larger tract can trigger the county's subdivision process, so ask before buying a split parcel.

Building in Doña Ana County: questions

Start the survey

How much does a barndominium cost in rural Doña Ana County?

The land work often outweighs the building choices. A new well, a septic system, a graded pad with its runoff pond and a long driveway can add up before the frame arrives. We keep no public price list; the barndominium cost guide sets out sourced ranges, and the survey lets us price plans and a kit against your actual tract.

Do I need a building permit for a barndominium in Doña Ana County?

Yes. In the unincorporated county the Building Services Division issues the building permit after the other county departments sign off, and each trade needs its own permit. A homeowner permit is possible only for the owner's primary residence, with the owner doing the major portion of the work by dollar value and any subcontracted trades licensed; the county adds its own acknowledgement forms. Inside Las Cruces the city issues permits instead; see the Las Cruces page.

Are pole barn homes a good fit for county acreage here?

They can be. Pole barn homes and other post frame homes are reviewed as dwellings, so they need the same septic, water and ponding items as any house. Like other metal building homes, the open span suits a shop and living space under one roof. Our post-frame homes page explains how we draw them for a New Mexico-licensed contractor to erect.

Can I order barndominium kits for land outside Las Cruces?

Yes. We supply barndominium kits with drawings that carry the truss specifications and energy compliance paperwork the county checklist asks for, and we check the site plan items with you so the application is not held for missing pieces.
