New Mexico: Rent Increase Notice Requirements

New Mexico's notice rule

New Mexico expressly regulates rent-increase notice in NMSA 1978 §
47-8-15(F). For a month-to-month residency, the owner must give the resident
written notice of the proposed increase at least 30 days before the periodic
rental date specified in the agreement. For a fixed term, notice is due at
least 30 days before the term ends. For a periodic residency shorter than one
month, the owner must give one full rental period's written notice before the
first increased payment.

The statute requires notice of the proposed increase but does not prescribe a
special statewide form. It also does not vary the lead time by the percentage
increase or impose a once-per-year frequency limit.

Amount and fixed terms

New Mexico sets no statewide percentage or CPI formula for an ordinary
residential increase. A local-law question should still be checked separately
for the property and tenancy.

For a fixed term, § 47-8-15(F) places the notice point 30 days before the
term ends, not during the term. The New Mexico Courts' current landlord-tenant
guidance likewise states that rent cannot increase during the period specified
by a written lease and that an automatically renewing annual lease requires
notice 30 days before the current agreement ends.

Remedies and common questions

Does every New Mexico tenant get 30 days?

No. Thirty days applies to month-to-month residency and to notice before a
fixed term ends. A periodic residency shorter than one month receives one
rental period before the first increased payment.

Is there a statewide cap on the amount?

No statewide percentage or formula cap applies to the ordinary tenancy covered
here. The notice rule controls timing, not amount.

What if the owner violates the notice rule?

Section 47-8-15 does not state a special damages figure. Under current §
47-8-48(A), however, a party may sue to enforce a provision of the Uniform
Owner-Resident Relations Act, and the prevailing party is entitled to
reasonable attorney fees and court costs.
