New Mexico will fund starter homes smaller than many HOA covenants allow
2026-09-15 · New Mexico · Legislation
New Mexico created a zero-interest loan programme for first-time buyers in 2026. Its size limits are a direct hit on the minimum-square-footage and minimum-lot-size covenants that are standard in older New Mexico subdivisions.1
What was enacted
House Bill 200, the New Homes for New Mexico Program, Laws 2026 Chapter 38, signed March 5, 2026 and effective May 20, 2026. It adds a section to the Affordable Housing Act creating a zero-interest deferred loan programme at the New Mexico Mortgage Finance Authority, paired with builder-side size limits.
The size caps
“An eligible builder shall: (1) not build a starter home that exceeds one thousand eight hundred square feet; (2) not build a starter home on a lot that exceeds five thousand square feet; (3) complete construction on a starter home within three years of program selection; and (4) build starter homes that are affordable to an eligible buyer.”
The loan
It bears “an annual interest rate of zero percent,” and is repayable on “the sale of the property… or … the failure of the eligible buyer to occupy the property… as the eligible buyer's principal residence.”
The buyer must never have owned a home, must earn below 120 percent of county area median income for a family of four, and must live in the home as a primary residence. Loans are capped at $50,000, rising for a home “within the jurisdictional boundaries of a high-cost county” — defined as “Los Alamos, Santa Fe or Taos county.”
The Mortgage Finance Authority must still write rules before loans flow.
The collision
Nothing in HB 200 preempts a covenant. So a declaration requiring, say, 2,000 finished square feet does not become unenforceable — it simply excludes that neighbourhood from the programme.
That is a quieter consequence than preemption and in some ways a more significant one. The state has defined what a starter home is, in numbers, and attached money to the definition. Communities whose documents sit outside those numbers are outside the programme by their own choice, made decades ago by a developer who was not thinking about this.
Who this actually affects
Associations with undeveloped infill lots. A community that still has buildable lots and a minimum-size covenant above 1,800 square feet has, in effect, decided that no state-funded starter home will be built there.
Developers still holding declarant rights. A declarant drafting or amending a declaration now has a concrete reason to set minimum sizes at or below the programme's caps, or to omit a minimum entirely.
Boards considering amendments. Minimum-size covenants were written to protect property values against small or non-conforming construction. Whether that reasoning still holds in a state where the legislature is funding 1,800-square-foot homes on 5,000-square-foot lots is a question a membership can answer either way — but it should be answered deliberately.
The pattern this belongs to
New Mexico has been legislating around housing size and lot dimensions for two sessions, and every measure that would have touched covenants failed or was narrowed.
Two accessory dwelling unit bills died — HB 554 in 2025, which passed the House 50–10, and HB 17 in 2026 — and both, in the form that actually moved, would have overridden only association restrictions “implemented after the effective date” of the act, leaving every existing covenant standing. A 2026 bill that would have barred local governments from imposing lot-size requirements in residential zones died after two referrals, and it bound only municipalities, never covenants.
HB 200 fits the pattern exactly: the state changes what it funds and what municipalities may do, and leaves the recorded declaration alone.
What now falls to a board
What the declaration's minimum dwelling size is, in square feet, and whether it measures finished, heated, or gross area — older documents are frequently ambiguous. Whether there is a minimum lot size or a lot-consolidation restriction. And whether any buildable lots remain.
An association with no remaining lots is unaffected in practice. One with lots left has a live question, and the state has just put a number on one side of it.
What to watch
The Mortgage Finance Authority's rules, which will set eligibility criteria for builders, buyers and starter homes, and the 2027 legislative session, which convenes January 19 with prefiling from January 4. Reporting indicates housing will be a priority again, with an incentive-based approach to local governments replacing the preemption bills that failed twice.
