Santa Fe County will certify your defensible space — then you must keep it that way forever
Santa Fe County will certify your defensible space — then you must keep it that way forever
2026-09-15 · New Mexico · Regulation
Santa Fe County will inspect a property and issue a letter confirming its defensible space, expressly so the owner can get insurance. The certificate comes with a permanent obligation — and one that many mountain-community covenants forbid.1
What the certification is for
The Fire Marshal's regulations state the purpose in their own opening paragraph:
“Pursuant to the authority vested in the Fire Marshal by Section 104.2 of the 2021 International Wildland Urban Interface Code (IWUIC), which is a part of Santa Fe County Ordinance 2023-06, the Fire Code, these regulations are adopted… to establish the process by which property owners within the Wildland Urban Interface Area can obtain a letter confirming the extent to which the property complies with the Fire Code requirements and recommendations pertaining to defensible space. The Fire Marshal anticipates that issuance of Certifications will encourage compliance with Fire Code requirements and allow property owners to obtain property insurance.”
What it requires
A written request naming the property, proof of ownership, written authorization for the Fire Marshal to enter and inspect, contact details, and “A Fuel Modification Plan in compliance with 2021 IWUIC Section 603.” Inspections are limited to once per twelve-month period, plus one re-inspection after a failure.
And it does not end
“Property owners are required to comply with their submitted Fuel Modification Plan. Failure to maintain a Fuel Modification plan shall constitute a basis for denying any application for a permit, or issuance of future certifications regarding compliance with defensible space requirements of the Fire Code.”
“Property owners must maintain documentation of compliance with the Fuel Modification Plan. Documentation can include photographs, videos, contracts with those who undertake fuel-reduction measures and other types of records.”
The covenant collision, item by item
Typical New Mexico foothill and mountain declarations do three things the wildland-urban interface code works against.
They forbid removing mature trees without architectural committee approval. Defensible space, as the code defines it, is an area “where material capable of allowing a fire to spread unchecked has been treated, cleared or modified to slow the rate and intensity of an advancing wildfire.” Section 603 of the code governs modifying the fuel load adjacent to structures; Section 604 sets out the maintenance requirements for that space. An owner who must clear to certify, and must ask permission to clear, is between two authorities.
They mandate native vegetation screening or minimum landscape buffers. Screening plantings close to a structure are precisely the fuel the plan is meant to modify.
They prohibit visible propane tanks and woodpiles, which pushes both close to the house. Section 606 of the code prohibits LP-gas containers or tanks except within defensible space, and Section 607 governs the storage of firewood and combustible materials.
Why this reaches the association and not just the owner
The certificate exists to obtain property insurance. So the owner who cannot clear is the owner who may not be insurable — and in a community association, individual insurability feeds directly into the association's own position: the master policy, the lender requirements that attach to every unit, and the underwriting of the community as a whole.
That connection is not theoretical in New Mexico right now. The Superintendent of Insurance reported more than 6,200 homeowner policies non-renewed in 2025, the highest figure on record and nearly triple 2021's. An association whose covenants prevent the mitigation an insurer wants to see is, in a real sense, underwriting its own non-renewal.
Los Alamos went further, on materials
Los Alamos County adopted the wildland-urban interface code by ordinance following a council vote in May 2025, designating itself a wildland-urban interface area within a Class 1 fire hazard zone — the highest level of risk. The ordinance adopts the code's Chapter 5 on Class 1 ignition-resistance construction and materials, so that new construction or major repairs must use fire-resistant materials for roofs, exterior walls, decks and other structures.2
Because those standards bite on “new construction or major repairs,” the collision arrives at re-roofing time: an ignition-resistant roof assembly in a profile or colour the declaration's roofing schedule never contemplated.
What a board in fire country should do now
Read the architectural standards against the code, before an owner asks. Tree removal, vegetation buffers, propane tank screening, woodpile placement and roofing materials are the five provisions most likely to conflict. A committee deciding each application on its own is producing inconsistent answers to a question with one board-level answer.
Consider amending rather than waiving. Case-by-case waivers accumulate into the selective-enforcement problem, and they leave the covenant on the books to catch the next owner.
Do the common-element work. Defensible space around association-owned buildings and on common land is the board's own responsibility, and it is the mitigation nobody else can do. New Mexico has made $10 million available in grants for exactly this kind of work — clearing trees near structures, vent screening, more flame-resistant roofing — most of which, in a community association, is common-element work.
