New Mexico regulates residential tenancies through the Uniform Owner-Resident Relations Act, NMSA 1978 sections 47-8-1 through 47-8-52, a statute that calls landlords “owners” and tenants “residents” and reads more like a neutral contract code than a landlord-friendly or tenant-friendly manifesto. Its signature features are precise: deposits are capped by lease length, the return clock is 30 days, rent increases need 30 days’ written notice, and evictions start with a 3-day notice.
New Mexico is also one of the few states that bans rent control outright. The Rent Control Preemption Act (NMSA 1978 § 47-8A-1) forbids cities and counties from capping rents, and a 2025 attempt to repeal it stalled — so Albuquerque and Santa Fe cannot adopt rent stabilization even if they want to.
Enforcement runs through the magistrate courts (and the metropolitan court in Bernalillo County), which handle both evictions and the deposit claims tenants bring. This guide covers deposits, pets, rent increases, repairs, and evictions under New Mexico law. It is general information, not legal advice.
| Governing law | NMSA 1978 §§ 47-8-1 to 47-8-52 (Uniform Owner-Resident Relations Act) |

| Security deposit cap | 1 month’s rent for leases under 1 year; no cap on annual leases (interest owed if over 1 month’s rent) |
| Deposit return deadline | 30 days after the later of termination or departure, with an itemized list |
| Wrongful retention penalty | Forfeiture of the right to withhold, plus court costs and attorney’s fees; $250 more in bad faith |
| Rent increase notice | 30 days in writing for month-to-month tenancies (§ 47-8-15(F)) |
| Nonpayment notice to quit | 3 days (§ 47-8-33) |
New Mexico Rental Law at a Glance
New Mexico’s Uniform Owner-Resident Relations Act (UORRA) covers most residential rentals, from single-family houses to apartments, and sets out the full landlord-tenant relationship: deposits, maintenance, access, notice, and remedies. The statute deliberately uses the words “owner” and “resident,” and courts apply it without much sympathy for sloppy paperwork — deadlines are deadlines.
The UORRA’s structure is practical: the owner must maintain the premises, the resident must not damage them or withhold rent except as the statute allows, and either side can end a tenancy on the statutory notice. Federal law, including the lead-based paint disclosure for pre-1978 housing, applies on top, and local housing codes in Albuquerque, Santa Fe, and Las Cruces add inspection and maintenance layers.
Security Deposits: A One-Month Cap for Short Leases
For a lease of less than one year, a New Mexico owner cannot demand a deposit larger than one month’s rent. For an annual lease there is no cap, but if the deposit exceeds one month’s rent the owner must pay annual interest at the passbook savings rate (§ 47-8-18(A)). Prepaid last month’s rent is treated separately and does not count against the cap.
Within 30 days after the later of the termination date or the resident’s departure, the owner must return the balance and provide a written itemized list of deductions (§ 47-8-18(C)). The statute expressly forbids retaining anything for normal wear and tear. Miss the deadline and the owner forfeits the right to keep any portion, forfeits the right to sue for damage, and owes court costs and reasonable attorney’s fees — plus a flat $250 civil penalty if the retention was in bad faith.
Pet Deposits and Pet Rent in New Mexico
New Mexico does not cap pet deposits or pet rent, so the amounts are whatever the lease says. Label them clearly: a refundable pet deposit is part of the security deposit and must be returned on the 30-day schedule, while pet rent is a monthly charge that is not refundable.
Assistance animals are not pets — no pet deposits or pet rent can be charged for them, though the owner may ask for reasonable documentation of the disability-related need under fair-housing rules. New Mexico’s dry climate also makes evaporative (“swamp”) cooler maintenance a recurring repair issue; spell out who services the cooler in the lease.
Rent Increases and the Ban on Rent Control
New Mexico has no statewide rent control, and the Rent Control Preemption Act (§ 47-8A-1) bars local governments from enacting their own — so no New Mexico city can cap rents. What the law does fix is notice: for a month-to-month tenancy, a rent increase requires written notice at least 30 days before the rent due date on which it takes effect (§ 47-8-15(F)). A fixed-term lease locks the rent for the term unless it contains an escalation clause.
Retaliatory increases are illegal: an owner cannot raise rent or cut services because a resident complained about habitability, reported a code violation, or joined a tenants’ organization (§ 47-8-39). Albuquerque has debated a Renters’ Bill of Rights that would add local notice and protection rules — check the city council record to see whether it is in effect for your address.
Habitability, Repairs, and Tenant Remedies
New Mexico owners must maintain the premises in a habitable condition (§ 47-8-20). When a repair is needed, the resident gives written notice specifying the failure, and the owner has 7 days to remedy it or make a reasonable attempt (§ 47-8-27.1). If the owner does not, the resident may terminate the lease or seek a rent abatement reflecting the diminished value of the unit (§ 47-8-27.2), and may ask a court to order the repairs.
There is no repair-and-deduct remedy in New Mexico, so do not subtract repair costs from rent on your own — that invites a nonpayment eviction. For a total failure of an essential service such as heat or water, the emergency timeline applies and the resident can seek immediate court relief. Document everything: dated written notices, photos, and records of calls to code enforcement.
Evictions and Termination in New Mexico
Nonpayment of rent starts with a 3-day written notice to pay or vacate (§ 47-8-33); if the rent is not paid, the owner files in magistrate court (or metropolitan court in Bernalillo County). Other breaches follow their own statutory notice periods, and termination of a month-to-month tenancy requires 30 days’ written notice. Self-help — changing locks, removing belongings, cutting utilities — is illegal in New Mexico.
A resident served with an eviction should file a written response by the deadline and can raise defenses such as the owner’s failure to repair, retaliation, or improper notice — and can counterclaim for deposit violations, which can offset the rent claim entirely.

Resolving New Mexico Disputes
Magistrate courts hear landlord-tenant cases, including deposit claims, up to $10,000, and the metropolitan court in Bernalillo County handles the same range for Albuquerque residents. The process is informal and designed for self-represented parties, and the filing fee is modest.
Start with a written demand letter citing § 47-8-18 and giving the owner a deadline — most deposit disputes settle at this stage. Then file in the county where the property sits with the lease, photos, written notices, and proof of mailing. New Mexico Legal Aid, Law Access New Mexico, and HousingNM all publish plain-language guides to the eviction and deposit process.
