New Mexico Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights

New Mexico caps security deposits at one month's rent for leases under one year and requires landlords to return the deposit within 30 days of move-out. Unless the lease sets different terms, landlords must give 24 hours of written notice before entering a rental unit. Late fees are capped at five percent of the rent for each rental period the tenant is in default, and rent control is banned statewide under NMSA 47-8A-1.

Security deposits in New Mexico

New Mexico's Owner-Resident Relations Act limits security deposits to one month's rent when the lease is for less than one year. Under an annual rental agreement a landlord may take more than one month's rent, but NMSA 47-8-18(A)(1) then requires the landlord to pay the tenant interest once a year, at the passbook rate allowed to New Mexico savings and loan associations, on the whole deposit rather than only on the amount above one month's rent. What the statute obligates is that annual interest payment. It does not require the landlord to park the money in a separate interest-bearing or escrow account. At move-out, the landlord has 30 days to return the deposit along with an itemized written statement of any deductions. Allowable deductions cover unpaid rent, cleaning costs beyond normal wear and tear, and damage caused by the tenant.

If the landlord misses the 30-day deadline or fails to provide the required itemization, the tenant may pursue the full deposit in Magistrate or District Court. NMSA 47-8-18(D) sets out what a landlord loses by missing that deadline: the right to withhold any part of the deposit, the right to assert a counterclaim in a suit brought to recover it, and the right to bring a separate action against the tenant for damage to the property. The landlord is also liable for the tenant's court costs and reasonable attorney fees. Under Subsection E, a landlord who retains a deposit in bad faith owes the tenant a civil penalty of $250. The statute does not provide for double the amount wrongfully withheld.

Normal wear and tear is not a valid deduction. That standard covers minor scuffs, small nail holes from pictures, and fading from sunlight. Damage such as stained carpets, broken fixtures, or unauthorized alterations may legitimately be deducted.

When can a landlord enter? Notice rules

A New Mexico landlord must give the tenant 24 hours of written notice before entering the rental unit. The statutory right to enter covers inspections, repairs, improvements, and showings to prospective tenants or buyers. Two qualifications matter. NMSA 47-8-24(A)(1) sets the 24-hour period as the default rule and applies it unless the owner and resident have agreed on something different, so a lease can change it. NMSA 47-8-24(A)(2) takes a short list of entries outside the notice requirement altogether: repairs or services the tenant asked for, if the landlord performs them within seven days of the request, and entries where the landlord is accompanied by a public official conducting an inspection or by a cable television, electric, gas, or telephone representative. Entry must occur at a reasonable time, which is generally understood as normal business hours.

The 24-hour notice requirement can be satisfied by written delivery to the unit, leaving notice at the door, or using another means reasonably calculated to inform the tenant. Verbal notice alone, while sometimes accepted in practice, does not satisfy the written requirement under NMSA 47-8-24.

Emergency entry is an exception. A landlord may enter immediately when there is an immediate threat to the property or to another person's safety, such as a gas leak or burst pipe. After an emergency entry, the landlord must notify the tenant as soon as reasonably practicable.

A landlord who repeatedly enters without proper notice is engaging in what the statute treats as harassment of the tenant, which can give the tenant grounds to terminate the lease and seek damages.

Ending a lease: notice to vacate

Either a landlord or tenant can end a month-to-month tenancy in New Mexico by giving at least 30 days of written notice before the next rent due date. The notice must clearly state the date the tenancy will end. A tenant who has a fixed-term lease is not subject to month-to-month notice rules; instead, the tenancy ends on the lease's expiration date unless renewed.

For nonpayment of rent, the landlord must give a 3-day written notice to pay or quit before filing for eviction. For a lease violation other than nonpayment, the landlord must give a 7-day notice to cure or quit. Tenants facing eviction for cause should consult New Mexico Legal Aid or a private attorney promptly.

For nonpayment situations, New Mexico's eviction notice generator at the eviction notice hub covers the proper notice forms. The squatters rights page for New Mexico explains adverse possession rules that apply once a person occupies property without permission for an extended period.

Repairs and the warranty of habitability

New Mexico recognizes an implied warranty of habitability under NMSA 47-8-20. The landlord must maintain the rental unit in a condition fit for human habitation, including functional heating and cooling, safe electrical systems, working plumbing, a weathertight structure, and freedom from pest infestations. These obligations cannot be waived by the lease.

New Mexico does not provide a statutory repair-and-deduct remedy. It does provide rent abatement, and under NMSA 47-8-27.2 that is a self-help remedy the tenant exercises directly, not something a judge has to authorize first. The tenant gives the landlord written notice of the conditions needing repair. If the landlord does not remedy those conditions within seven days of the notice, the tenant is entitled to abate rent.

The statute fixes the amounts rather than leaving them to a court's assessment of diminished value. Under Subsection A(1), the tenant may abate one-third of the pro-rata daily rent for each day from the date of the notice through the day the conditions are remedied, and may keep abating at that rate into later rental periods while the conditions go unrepaired. Under Subsection A(2), the abatement is one hundred percent of the rent for each day the dwelling is uninhabitable and the tenant is not living in it because of the condition. Abatement is not available for the failure or unavailability of an amenity.

Tenants should document all maintenance requests and the landlord's response (or lack of response) in writing. Photographs of the defect with date stamps, copies of written requests, and records of any landlord responses all serve as evidence in a habitability dispute. Abating rent under the statute is not the same as simply stopping payment. The written notice and the seven-day waiting period are conditions of the remedy, and oral notice does not satisfy them: in Cheng v. Rabey, 2023-NMCA-013, the New Mexico Court of Appeals affirmed the denial of abatement to a tenant who gave no written notice of the needed repairs until less than three weeks before he moved out and never actually withheld any rent. Keep the notice, the dates, and the arithmetic, because a tenant who abates may still have to defend the amount in a possession case.

If a landlord retaliates against a tenant for complaining about habitability, that retaliation is prohibited under NMSA 47-8-39. Prohibited retaliation includes raising rent, reducing services, or filing an eviction because of a protected tenant complaint made within the previous six months.

Rent, late fees, and rent control

New Mexico caps late fees by statute. Under NMSA 47-8-15(D), a landlord may charge a late fee only if the rental agreement provides for one, and the fee may not exceed five percent of the rent for each rental period the tenant is in default. The 2025 amendment to that subsection, effective June 20, 2025, cut the ceiling from ten percent to five percent, so leases written under the old rule may still recite a higher number than the law now allows.

Two further limits sit in the same subsection. The fee is calculated on rent alone, which means deposits, additional fees, and utilities are left out of the figure the percentage is applied to. And the landlord has to give notice of the late fee charged no later than the last day of the rental period immediately following the one in which the default occurred. A fee that is not in the lease is unenforceable, and so is a fee the landlord never noticed within that window. Most leases set a grace period of 3 to 5 days before the late fee applies, and the grace period, unlike the cap, is a matter of contract rather than statute.

Written notice of a rent increase is a statutory requirement in New Mexico, not a matter of practice. NMSA 47-8-15(F) allows a landlord to increase the rent in a month-to-month residency only by giving the tenant written notice of the proposed increase at least 30 days before the periodic rental date specified in the rental agreement, and in a fixed-term residency at least 30 days before the end of the term. For a periodic residency shorter than one month, the written notice has to come at least one rental period before the first increased payment.

Rent control is banned in New Mexico. NMSA 47-8A-1(A) prohibits a political subdivision or home rule municipality from enacting an ordinance or resolution that controls, or would have the effect of controlling, rental rates for privately owned real property. The same section writes in two limits on that ban. Subsection B leaves a state agency, county, or municipality free to manage or control its own property, and Subsection C exempts privately owned property for which federal, state, or local government benefits or funding have been provided under contract for the express purpose of providing reduced rents to low- or moderate-income tenants. Outside those situations, landlords may raise rents to market levels, subject to the written notice NMSA 47-8-15(F) requires.

If you have a landlord-tenant dispute in New Mexico

The first step in any dispute is documentation. Keep every communication with your landlord or tenant in writing, whether by text, email, or certified letter. If you make a verbal agreement, follow up in writing that same day to create a record.

For deposit disputes, a tenant may file in Magistrate Court (small claims jurisdiction up to $10,000) without an attorney. File in the county where the rental property is located. Bring your lease, move-in and move-out photos, and the 30-day deadline calculation.

The New Mexico Regulation and Licensing Department's Construction Industries Division handles housing-code complaints. The New Mexico Attorney General's Consumer Protection Division (nmag.gov) accepts complaints about unfair landlord practices. New Mexico Legal Aid (newmexicolegalaid.org) offers free civil legal services to qualifying low-income residents, including tenants facing eviction or wrongful deposit withholding.

Tenants facing eviction should act immediately. New Mexico eviction cases in Magistrate Court can move quickly, and missing a hearing typically results in a default judgment against the tenant. Consult an attorney or legal aid organization as soon as you receive a notice to quit.

This article is general legal information, not legal advice. Landlord-tenant rules vary by state and city and change, and some cities add their own ordinances. For advice about a specific situation, consult a licensed attorney or your state housing agency.

Frequently Asked Questions

How long does a landlord have to return my deposit in New Mexico?

A New Mexico landlord has 30 days after the tenancy ends and the tenant vacates to return the security deposit along with a written itemized statement of any deductions. Missing this deadline or failing to provide the itemization can expose the landlord to liability for the full deposit amount.

What is the maximum security deposit a landlord can charge in New Mexico?

For leases shorter than one year, the cap is one month's rent. Under an annual rental agreement a landlord may collect a larger deposit, but NMSA 47-8-18(A)(1) then requires the landlord to pay the tenant interest once a year, at the passbook rate, on the whole deposit and not just on the part above one month's rent. The statute requires that annual interest payment; it does not require a separate interest-bearing account.

How much notice must a landlord give to enter my apartment in New Mexico?

New Mexico law requires 24 hours of written notice before a landlord enters for inspections, repairs, or showings, and entry must occur at a reasonable time. That 24-hour rule is a default under NMSA 47-8-24(A)(1), so the owner and resident can agree to something different in the lease. It also does not apply to repairs or services the tenant requested if the landlord performs them within seven days, or to entries where the landlord is accompanied by a public official conducting an inspection or by a utility or cable representative. Emergency entry is allowed without notice when there is an immediate threat to safety or property.

How much notice is needed to end a month-to-month lease in New Mexico?

Either the landlord or the tenant must give 30 days of written notice before the next rent due date to end a month-to-month tenancy. A fixed-term lease ends on its expiration date and does not require this notice.

Can I withhold rent for repairs in New Mexico?

You can abate rent, and NMSA 47-8-27.2 does not require a court order to do it. The tenant gives the landlord written notice of the conditions needing repair, and if the landlord does not remedy them within seven days, the tenant is entitled to abate rent. The statute sets the amounts: one-third of the pro-rata daily rent for each day until the conditions are fixed, or one hundred percent of the rent for each day the dwelling is uninhabitable and the tenant is not living in it. The written notice and the seven-day wait are required, and oral notice does not count: in Cheng v. Rabey, 2023-NMCA-013, the court denied abatement to a tenant who put his repair requests in writing only shortly before moving out and never actually withheld rent.

Is there rent control in New Mexico?

There is no general rent control. NMSA 47-8A-1(A) prohibits political subdivisions and home rule municipalities from enacting an ordinance or resolution that controls rental rates for privately owned property. The section carves out two things: a government entity may still manage or control property it owns, and the ban does not reach privately owned property for which government benefits or funding have been provided under contract for the express purpose of providing reduced rents to low- or moderate-income tenants.

Can a landlord charge a late fee in New Mexico?

Yes, if the written lease provides for one. NMSA 47-8-15(D) caps the fee at five percent of the rent for each rental period the tenant is in default, and the fee is calculated on rent alone, not on deposits, other fees, or utilities. The landlord also has to give notice of the late fee no later than the last day of the rental period following the one in which the rent was late. A late fee not stated in the lease is unenforceable.
