Chaves County's building inspections office at One St Mary's Place in Roswell permits and inspects construction in the unincorporated county — over six thousand square miles of the Pecos Valley, the Llano Estacado escarpment and the plains east of it. The state codes the Construction Industries Division adopts apply, with the county administering them outside the incorporated municipalities.
The county's binding constraint is water. It sits above the Roswell artesian basin, one of New Mexico's declared groundwater basins, where the Office of the State Engineer administers appropriation and a well cannot simply be drilled because the water is there. On an unserved rural parcel the availability of a legal water right, and the terms on which one may be obtained, determines whether a dwelling is possible at all — a question that precedes the building code entirely.
This guide covers unincorporated Chaves County. Roswell, Dexter, Hagerman and Lake Arthur permit their own construction, and the county's eastern plains run to the Texas line with entirely separate requirements beyond it.
A declared basin means water is permitted, not found. The Roswell artesian basin is a declared groundwater basin administered by the Office of the State Engineer. A well requires a permit and an appropriation, not merely a drill rig — and on an unserved rural parcel the availability of a legal water right decides whether a house is possible. That question is answered before the parcel is bought, not after.
What requires a building permit in Chaves County?
New Mexico sets its codes once, at state level, and then divides the enforcement. The Construction Industries Division of the Regulation and Licensing Department adopts the statewide codes under the Construction Industries Licensing Act — the New Mexico Commercial Building Code at 14.7.2 NMAC and the New Mexico Residential Building Code at 14.7.3 NMAC, both adopting the 2021 International Codes as amended by the state, alongside the existing building, energy, mechanical, plumbing and electrical codes in the same chapter. Those codes are the standard everywhere in the state. What changes is who administers them: a municipality or county certified as a Local Enforcement Agency issues its own permits and carries its own inspections, and where no such agency exists the division does both itself. A home rule municipality may also adopt amendments more stringent than the state code, in which case the stricter provision governs. In Chaves County the practical questions are which authority issues the permit, whether local amendments apply, and the county's land use approvals and its groundwater constraints.
The adopted codes draw the exemption line. Ordinary repairs need no permit; construction, alteration, relocation, enlargement, replacement, repair, change of use or occupancy, and demolition of a building or structure all do. Detached one- and two-family dwellings and townhouses of not more than three storeys fall under the residential code; other buildings under the commercial code; and an existing building undergoing a change of occupancy, repair, alteration or addition falls under either the commercial code or the existing building code as applicable. Electrical, mechanical and plumbing work carries its own permits and its own state licences.
Typically permit required
- Construction, alteration, relocation, enlargement, replacement, repair, change of occupancy or demolition in unincorporated territory
- County land use, zoning and subdivision approval ahead of the building permit
- A permitted well and appropriation from the State Engineer, plus on-site liquid waste approval, on unserved parcels
- New buildings, additions and structural work, under the commercial or residential code as applicable
- Alteration, relocation, enlargement, replacement and repair of a building or structure
- Any change of use or occupancy, which brings the existing building code into the analysis
Often exempt
- Ordinary repairs that do not alter structure, egress or systems, and work the adopted codes place below the permit threshold
- Ordinary repairs that do not alter structure, egress or systems
- Painting, papering, flooring, cabinets and similar finish work
- Like-for-like replacement the adopted codes place below the permit threshold
- Small accessory structures below the threshold — zoning and any local amendment still apply
Local Enforcement Agencies and what they change
A Local Enforcement Agency is a municipality or county certified to administer permitting and inspections itself. In an agency jurisdiction the enforced code is still the state's, but the procedural pathway is local: the local building department takes the application, reviews the plans and inspects the work. Outside those jurisdictions the Construction Industries Division does all of it directly from its own offices. A home rule municipality may go further and adopt amendments more stringent than the state code, and where the two differ the stricter provision governs. Chaves County's layer is therefore its status, any amendments it has adopted, its zoning and platting, its fee schedule, and the declared artesian basin and the water right question it puts ahead of every rural project.
Who handles permitting in Chaves County?
The county building inspections office permits and inspects in unincorporated Chaves County, administering the state code alongside county land use and zoning. The Office of the State Engineer administers groundwater in the declared basin, the Construction Industries Division licenses contractors statewide, and Roswell and the smaller municipalities permit their own.

Permit types
Residential permits
A house in unincorporated Chaves County starts with the water right: a permitted well with an appropriation from the State Engineer, or a connection to an approved system. Then county land use, then the building permit against the New Mexico Residential Building Code as amended, with an on-site liquid waste system approved alongside on unserved land.
How New Mexico contractor licensing works
Unlike several of its neighbours, New Mexico licenses contractors at state level. The Construction Industries Division issues contractor licences under the Construction Industries Licensing Act across general building, general engineering, mechanical, electrical and plumbing classifications, each tied to a qualifying party who has passed the trade and business examinations. A licence is valid throughout the state, so the credential does not have to be re-earned in each jurisdiction — though a municipality may still require a local business registration. The division also licenses journeymen in the trades, and unlicensed contracting is an enforcement matter for the division rather than for Chaves County.
Commercial permits
Commercial and agricultural work in unincorporated Chaves County — the irrigated farming of the Pecos Valley, the dairy industry and the highway corridors — clears county land use, then plan review against the New Mexico Commercial Building Code. Water-intensive operations face the appropriation question at a scale that can determine the whole project.
Which authority issues the permit
The first question on any New Mexico project is not which code applies — that is settled statewide — but which office administers it. The larger municipalities operate as Local Enforcement Agencies with their own building departments; much of the rest of the state, including a good deal of unincorporated county territory, is permitted and inspected by the Construction Industries Division directly. Confirming jurisdiction before submitting an application is the step out-of-state design teams most often miss. Zoning, platting and site development are separately local in every case, and the division has no authority over them. In unincorporated Chaves County the Roswell artesian basin governs groundwater appropriation under the State Engineer, the Pecos River corridor brings floodplain review into the file, and the eastern plains carry their own access and service constraints across a very large area.
Chaves County permit costs and fees
Fees follow the county's schedule for unincorporated territory, with water rights and well permitting handled by the State Engineer and contractor licensing by the division.
| Item | Fee or rule |
|---|---|
| Building permit | The county's schedule, for unincorporated territory |
| County land use | Zoning and subdivision approvals ahead of the permit |
| Water right and well permit | Through the Office of the State Engineer in the declared basin |
| On-site liquid waste | Separate approval where the parcel is unserved |
| Trade permits | Electrical, mechanical and plumbing, by state-licensed contractors |
| City permits | Roswell and the smaller municipalities issue their own |
The water right is the first asset. In a declared basin, the water right is often worth more than the land it serves and is bought and sold separately from it. A rural Chaves County parcel advertised as buildable may carry no right at all — and acquiring one, where it is possible, is a transaction in its own right with its own market and its own timescale.
Trade permits and who may pull them
Electrical, mechanical and plumbing work is permitted separately and performed by contractors holding the matching state licence from the Construction Industries Division.
Permit required
- Unserved parcels — a permitted well and appropriation from the State Engineer before design
- Electrical — state-licensed electrical contractor; separate permit and inspection
- Mechanical — state-licensed mechanical contractor; separate permit, covering heating, cooling and refrigeration
- Plumbing and gas — state-licensed plumbing contractor; separate permit under the plumbing and gas codes
- Liquefied petroleum gas work, which the division regulates separately
Typically exempt
- Like-for-like replacement the adopted codes place below the permit threshold
- Work a homeowner may perform on their own residence where the administering authority allows it
How to apply for a Chaves County building permit
A Local Enforcement Agency issues its own permits; elsewhere the Construction Industries Division does it directly.
Zoning, platting and site development are local in every case, and the division has no authority over them.
A home rule municipality may adopt provisions more stringent than the state code, and the stricter provision governs.
The division licenses contractors statewide in the classification matching the work.
The commercial code, the residential code or the existing building code, depending on the building and the work.
Footing to final with the authority that issued the permit, then the certificate of occupancy.
Review, corrections and what actually causes delay
Chaves County reviews unincorporated work against the state code alongside its land use requirements. What delays a project here is a parcel bought without the water right established, a liquid waste system designed before the site evaluation, and the sheer distance an inspector covers across a county this size.
Inspections in Chaves County
Inspections follow the adopted codes' sequence — footing, foundation, framing, rough trades, insulation and final — and are requested from whichever authority issued the permit, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy for new buildings and changes of occupancy. Chaves County inspects the work it permits in the adopted codes' sequence, with the trades inspected on their own permits; the county's size means inspection scheduling repays being planned rather than assumed.

Frequently asked questions
Can I drill a well on my land?
Not without a permit and an appropriation. The Roswell artesian basin is a declared groundwater basin administered by the Office of the State Engineer.
Does the county permit inside Roswell?
No. Roswell and the smaller municipalities permit their own construction; the county covers unincorporated territory.
Which code applies?
The state code adopted by the Construction Industries Division, on the 2021 International Codes as amended.
What should I check before buying rural land?
Whether a legal water right exists or can be acquired — a parcel advertised as buildable may carry no right at all, and the right trades separately from the land.
Do I need a liquid waste approval?
On unserved parcels, yes — an on-site system is approved alongside the building permit.
Who licenses my contractor?
The Construction Industries Division, at state level, valid throughout New Mexico.
