Santa Fe County's growth management department at 240 Grant Avenue permits and inspects construction in the unincorporated county — the land around the capital, out to the Galisteo Basin, the Pojoaque Valley and the Sangre de Cristo foothills. The City of Santa Fe is a separate government permitting its own territory, and the shared name causes more confusion here than in any other New Mexico county.
The county's binding constraint is water. New Mexico administers groundwater through the State Engineer, the basin around Santa Fe is fully appropriated, and county development regulation requires an adequate and legal supply to be demonstrated before development proceeds. On an unserved parcel that means a permitted well with sufficient right, not simply the physical possibility of drilling — a distinction that has stopped a great many otherwise sound projects at the first stage.
This guide covers unincorporated Santa Fe County. The City of Santa Fe permits its own construction, Española sits partly in the county with its own arrangements, and the pueblos of Pojoaque, Nambé, Tesuque and San Ildefonso are outside county jurisdiction entirely.
Water rights come before the building permit. In a fully appropriated basin, an adequate and legal water supply must be demonstrated before development proceeds — which means a permitted well with sufficient water right, not merely the physical possibility of drilling one. It is the first question on an unserved Santa Fe County parcel and the one that most often ends a project.
What requires a building permit in Santa Fe 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 Santa Fe County the practical questions are which authority issues the permit, whether local amendments apply, and the county's water and land use requirements.
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
- Demonstration of an adequate and legal water supply on development in the unincorporated county
- Zoning, land use and terrain management approval from the county ahead of the building permit
- 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. Santa Fe County's layer is therefore its status, any amendments it has adopted, its zoning and platting, its fee schedule, and the water supply demonstration and the county's terrain and land use regulation.
Who handles permitting in Santa Fe County?
The growth management department is the permitting authority for unincorporated Santa Fe County, administering the state code alongside the county's land use, terrain management and water requirements. The City of Santa Fe permits its own, the Office of the State Engineer administers water rights, the Construction Industries Division licenses contractors statewide, and pueblo land is outside county jurisdiction.

Permit types
Residential permits
A house in unincorporated Santa Fe County starts with water: a permitted well with sufficient right, or a connection to an approved community system. Then zoning and terrain management, then the building permit against the New Mexico Residential Building Code as amended. Applicants should expect the county's review to take considerably longer than a published target suggests and plan the programme accordingly.
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 Santa Fe County.
Commercial permits
Commercial work in unincorporated Santa Fe County clears the water demonstration, land use and terrain management requirements, then plan review against the New Mexico Commercial Building Code. The county's development regulation is among the more demanding in the state, and pre-application engagement is worth more here than almost anywhere.
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 Santa Fe County the water supply requirement governs development in a fully appropriated basin, terrain management rules limit building on steep and ridgeline land, archaeological review may apply on ground disturbance, and the surrounding pueblos are outside county jurisdiction.
Santa Fe County permit costs and fees
Fees follow the county's schedule for unincorporated territory, with water rights, well permitting and land use approvals charged separately.
| Item | Fee or rule |
|---|---|
| Building permit | The county's fee schedule, for unincorporated territory |
| Water supply | Well permitting and water right acquisition, through the State Engineer |
| Land use and terrain management | County approvals ahead of the building permit |
| Trade permits | Electrical, mechanical and plumbing, by state-licensed contractors |
| Contractor licence | Issued by the Construction Industries Division, valid statewide |
| City permits | The City of Santa Fe issues its own |
Allow far more time than the target. Applicants report county permits taking many months against a published target of days, with limited response to telephone and email contact. Whatever the stated turnaround, a Santa Fe County programme should be built on the experienced timeline rather than the advertised one, and pre-application engagement in person is worth the trip.
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
- Development in the unincorporated county — demonstration of an adequate and legal water supply
- 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 Santa Fe 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
Santa Fe County reviews unincorporated work against the state code alongside its own land use and water requirements. What delays a file here is a parcel bought without the water right established, a design that ignores terrain management on a ridgeline site, and a programme built on the published turnaround.
Inspections in Santa Fe 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. Santa Fe County inspects the work it permits in the adopted codes' sequence, with the trades inspected on their own permits; inside the city, inspection is the city's.

Frequently asked questions
Is the county the same as the City of Santa Fe?
No. They are separate governments with separate departments; the county permits unincorporated territory and the city permits its own.
Do I need water rights to build?
On an unserved parcel in the unincorporated county, an adequate and legal water supply must be demonstrated — a permitted well with sufficient right, not merely the ability to drill.
How long does a county permit take?
Applicants report many months against a published target of days; build the programme on the experienced timeline and engage before applying.
What is terrain management?
County regulation limiting building on steep slopes and ridgelines, applied alongside zoning ahead of the building permit.
Which code applies?
The state code adopted by the Construction Industries Division, on the 2021 International Codes as amended.
Is pueblo land inside county jurisdiction?
No. The surrounding pueblos are outside county permitting jurisdiction entirely.
