New Mexico Landlord-Tenant Laws: The Complete 2026 Overview

New Mexico security deposits are governed by NMSA Section 47-8-18. For an unfurnished unit on a lease of less than one year, the deposit is capped at one month’s rent; longer leases have no statutory cap, but any deposit a landlord holds for more than one year must earn interest for the tenant. When the tenancy ends, the landlord must return the balance within thirty days after the tenant vacates, along with a written itemized statement of any deductions. The thirty-day clock starts at surrender, and failure to itemize forfeits the right to withhold any portion. A landlord who wrongfully retains the deposit is liable for damages plus the tenant’s attorney’s fees, with bad faith typically presumed when the landlord misses the deadline. Disputes are heard in Magistrate or Metropolitan Court.

New Mexico is not a just-cause state – a landlord may decline to renew a lease for almost any lawful reason. To evict for nonpayment, the landlord must first serve a written three-day notice to pay or vacate; for a lease violation, the notice must cite the specific breach. If the tenant does not cure or leave, the landlord files a petition for restitution in Magistrate Court, or the Metropolitan Court in Bernalillo County. The tenant’s response window is three days after service, and a hearing is typically set ten to thirty days after filing. Uncontested cases usually resolve in about thirty to sixty days from notice to writ. Self-help evictions – changing locks, removing doors, or shutting off utilities – are illegal, and only a sheriff or constable acting on a writ of restitution may physically remove a tenant.

Unlike the states that leave entry to a vague reasonableness standard, New Mexico fixes a number. Under NMSA Section 47-8-24, unless the parties agree otherwise, an owner must give the resident at least twenty-four hours’ written notice before entering, must state the purpose, and may enter only at reasonable times – except in a genuine emergency such as fire, flooding, or a gas leak, which permits immediate entry. Legitimate reasons include inspection, repairs, and showing the unit to prospective tenants or buyers. The notice may not be a pretext for harassment. A landlord who enters repeatedly without lawful notice exposes themselves to real consequences: the resident may obtain injunctive relief, terminate the lease, and recover damages. Because the rule is a bright line, the safest practice is a dated written notice for every non-emergency visit.

New Mexico has no rent control. The Rent Control Preemption Act, NMSA Section 47-8A-1, bars every city and county from capping, controlling, or stabilizing rent on private residential housing, so no local ordinance can limit an increase and there is no statutory ceiling on how much a landlord may charge at renewal. During a fixed-term lease the rent is locked at the agreed figure – a landlord cannot raise it mid-term unless the written lease expressly allows it. For a month-to-month tenancy, the landlord must give at least thirty days’ written notice under NMSA Section 47-8-15, stating the new rent and the effective date. The limits that do apply are anti-retaliation and anti-discrimination: a landlord may not raise the rent to punish a tenant for a good-faith code complaint or the exercise of a legal right, and may not raise it on a basis that violates fair-housing law.

New Mexico is one of the states that puts a hard number on late fees. Under NMSA Section 47-8-15(D), a late fee may not exceed ten percent of the rent for the rental period that is past due, and it must be stated in the written lease to be enforceable. A fee that is not in the lease cannot be charged, and a fee dressed up as a penalty rather than a reasonable estimate of the landlord’s costs is unenforceable even if it stays under the cap. New Mexico sets no statutory grace period, so any grace window is contractual – most leases allow three to five days before the fee attaches. The fee cannot be imposed until the rent is actually late, and combining a late fee with interest is risky because the total charges must remain reasonable and the late-fee portion still cannot exceed the ten-percent ceiling.

The Uniform Owner-Resident Relations Act, NMSA Section 47-8-1 et seq., puts a warranty of habitability on every New Mexico rental. Under Section 47-8-20 the owner must keep the premises fit and habitable – working plumbing, heating, electrical, and structural safety. The tenant triggers the duty with written notice specifying the defect, and if the owner does not make a reasonable attempt to fix it within seven days, the tenant has options. Under Section 47-8-27.1 the resident may terminate the lease on a date not less than seven days after the owner receives notice; under Section 47-8-27.2 the resident may abate the rent – one-third of the pro-rata daily rent for each day the condition persists, or one hundred percent for each day the unit is uninhabitable and the resident does not occupy it; and under Section 47-8-28 the resident may, where authorized, arrange a repair and deduct the cost, capped at the greater of five hundred dollars or one month’s rent. Retaliation against a tenant who asserts these rights is barred.

New Mexico recognizes a handful of protected reasons a tenant may end a lease early. The clearest is an uncured habitability breach: under NMSA Section 47-8-27.1 a resident who gives written notice of a serious defect may terminate if the owner fails to make a reasonable repair effort within seven days. Military servicemembers may terminate under the federal Servicemembers Civil Relief Act, 50 U.S.C. Section 3955, by delivering written notice with a copy of active-duty, permanent-change-of-station, or deployment orders – New Mexico’s own act has no separate military provision. Domestic-violence victims do not get a stand-alone early-termination statute, but Section 47-8-33(J) gives a defense against a writ where the tenant holds or has filed for a protective order under the Family Violence Protection Act. For a tenant who simply leaves without a ground, Sections 47-8-6 and 47-8-34 impose a duty on the owner to mitigate by making a reasonable effort to re-rent, so the departing tenant owes only the vacancy gap, not the entire remaining term.

Ending a New Mexico tenancy depends on its type. A month-to-month tenancy is terminated by at least thirty days’ written notice under NMSA Section 47-8-37, from either party. A fixed-term lease generally runs to its end date and cannot be cut short without a statutory ground or a mutual written agreement. New Mexico does not require just cause to decline to renew a lease, and automatic-renewal clauses are enforceable when the lease discloses them properly. A tenant who stays past the lease end date becomes a holdover; New Mexico permits recovery of actual damages and attorney’s fees against a willful holdover under Section 47-8-37, and the owner must pursue possession through a court petition rather than self-help. When any tenancy ends, the deposit rules of Section 47-8-18 still govern the move-out, including the thirty-day return and itemization.

For an actual pet, New Mexico imposes no separate pet-fee statute, but a pet deposit is treated as part of the security deposit and is governed by the Section 47-8-18 return and cap rules. Private landlords may set reasonable pet policies, including breed or size restrictions, and charge a pet deposit if the lease provides for it. Assistance animals are treated completely differently. Under the federal Fair Housing Act and the Americans with Disabilities Act, a service animal or emotional support animal is not a pet – a landlord may not charge any pet deposit, fee, or rent, and may not apply a breed, weight, or no-pet restriction to it. When the disability or the animal’s role is not obvious, the landlord may request reliable documentation from a licensed professional but may not demand certification or registration. The New Mexico Human Rights Act, NMSA Section 28-1-7, layers state fair-housing protection on top of the federal rules. The tenant remains liable for any actual damage the animal causes.

New Mexico leaves most of tenant screening to the landlord, so the binding rules are largely federal. With the applicant’s written authorization, a landlord may pull a consumer report covering credit, rental history, income, and criminal convictions – the Fair Credit Reporting Act requires a permissible purpose and consent first. New Mexico does not cap application or screening fees, but they should be reasonable, tied to the actual cost of screening, and charged consistently to every applicant. If a denial, a higher deposit, or a co-signer requirement rests in any part on a consumer report, the FCRA requires an adverse action notice naming the reporting agency and explaining the right to a free copy and to dispute it. Blanket criminal-record bans are risky under HUD’s disparate-impact guidance, so an individualized assessment is safer. The New Mexico Human Rights Act and the federal Fair Housing Act bar screening that discriminates on a protected basis, and a consistent, documented process is the best defense if a dispute arises.
