How does a New Mexico landlord lawfully end a tenancy, and when may a tenant leave early?

Landlord: 30 days. Tenant: 30 days.

The two tracks count to different dates, and the difference matters on a calendar. A month-to-month notice must be given at least 30 days before the periodic rental date named in the notice, so it counts back from a rent date and the tenancy ends on a rent date rather than 30 days after service. A week-to-week notice must be given at least seven days before the termination date named in the notice, so it counts forward from delivery and may end the tenancy on any day. The Act does not define what the periodic rental date is; the nearest thing to a definition anywhere in it is the rule that the date of one month to the same date of the following month makes a term of one month. So a month-to-month tenant who gives notice on the 20th with rent due on the 1st ends the tenancy on the 1st of the month after next, not on the 20th of the following month. A notice that gives less than 30 days is not void: the courts treat it as effective for the next rent date after that.

Whether the termination date must fall on a rental-period boundary or a rent-due date differs between tenancy types or is not settled by the statute; the rule for each is stated above.

Tiers: Two tracks by the length of the rental period: 30 days for a month-to-month residency, counted to a periodic rental date, and seven days for a week-to-week residency, counted to a termination date the notice names. There is no year-to-year track in the Act at all; the old six-month rule for a year-to-year holdover comes from a 1960 decision the compilers themselves mark as decided under former law. No period turns on how long the tenant has lived there, the building type, the size of the landlord's holdings, or the county.

A lease may not change the period. The Act carries a bilateral anti-waiver clause covering everything in it: no rental agreement may provide that the resident or the owner agrees to waive or forego rights or remedies under the law. The notice section contains no unless-otherwise-agreed escape, which sets it apart from the rent and rent-payment sections that do. A landlord who deliberately uses a lease term known to be prohibited owes the resident damages and attorney's fees, and a court may separately limit an inequitable lease provision to avoid an inequitable result.

A statute requires the landlord's and tenant's periods to be equal, or bars a lease from imposing a longer period on one side.

Source of the period: a termination-notice statute states it.

The owner or the resident may end a month-to-month residency by written notice given at least 30 days before the periodic rental date named in the notice, and a week-to-week residency by written notice given at least seven days before the termination date named in the notice. The section names both sides in the same sentence and imposes the same period on each, so New Mexico is symmetric by its own text, and the notice must be in writing whoever gives it. It has never been amended since 1975. The Supreme Court of New Mexico has added three rules a landlord can trip over. A notice must be definite enough to inform the tenant that the landlord wants the tenant to leave. A notice to quit coupled with an offer to let the tenant stay at a higher rent is not a termination notice at all, so a landlord who bundles the two has served nothing. And a notice that is short of the 30 days is not void but is effective for the next rent date after the one it named. On the tenant's side, the same court has allowed a landlord to apply the security deposit against deficient rent without an itemization where the tenant left without giving the 30 days, so the tenant's notice carries a real price for skipping it.

No: no statewide rule requires a reason, and no statute expressly authorizes local ordinances.

Local ordinances: no statute or decision addresses them. No New Mexico statute addresses local just-cause or eviction-control ordinances one way or the other, and no appellate decision does either. What the state does preempt is the amount of rent: an article of the property chapter added in 1991 bars any 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, with a carve-out for property receiving government benefits or funding under contract for the express purpose of providing reduced rents to low- or moderate-income tenants, and a saving clause for a government's management of its own property. That is a rent-rate rule; it does not name eviction, termination, non-renewal, or grounds. Bills to repeal it died in 2025 and again in 2026. The rent-regulation posture itself is carried on the rent-increase page.

No reason is required to end a periodic residency or to let a fixed term expire in New Mexico. The Act's notice section asks only for writing and the period; nothing in it, and nothing elsewhere in the property chapter, the domestic-affairs chapter, or the military chapter, conditions a no-cause termination or a non-renewal on a ground. The Act does contain cause-based routes, but they all run the other way, as owner remedies: a seven-day notice to cure a breach, a three-day notice for unpaid rent, and a three-day notice for a substantial violation drawn from a closed list of seven acts. Those belong to the eviction page. The only limit that resembles a ground requirement is the bar on retaliation, which the annotations note reaches a refusal to renew a month-to-month residency where the owner is retaliating against a resident for complaining; that is covered on the habitability page.

A statute converts the tenancy to a periodic one after the term by operation of statute, with no notice rule.

The conversion is written into the statute but its trigger is the owner's consent, not the acceptance of rent and not the mere passage of time. If the owner consents to the resident's continued occupancy, the Act's residency-term rule takes over: unless the rental agreement fixes a definite term, the residency is week-to-week for someone who pays weekly rent and month-to-month in every other case. The new periodic residency then carries the ordinary seven-day or 30-day notice. Where the owner does not consent, no new tenancy arises and the owner may bring an action for possession.

A fixed-term residency in New Mexico ends on its stated date and neither side owes the other any notice of non-renewal; the Act has no non-renewal notice and no reminder before an automatic-renewal clause takes effect. What happens next depends entirely on the owner. If the owner consents to the resident staying, the statute converts the residency to month-to-month, or to week-to-week where rent is paid weekly, and the ordinary notice periods apply from then on. If the owner does not consent, the resident is a holdover and the owner may sue for possession. So a landlord who wants the tenancy to end on the lease's own date should be careful about what counts as consent, and a landlord who is content for the tenant to stay should understand that the result is a periodic residency that now takes 30 days to end.

A resident who stays after the term or after a termination, without the owner's consent, holds no new tenancy: the owner may bring an action for possession under the Act's court procedures. A resident who stays with the owner's consent becomes a month-to-month resident, or a week-to-week resident where rent is paid weekly, by operation of the statute.

Damages: An enhanced measure that attaches only to a wilful or bad-faith holdover. Qualifiers: attorney fees added by statute.

New Mexico states no holdover multiplier at all: no double rent, no treble damages, no liquidated percentage, and no per-day enhancement. An ordinary holdover exposes the resident to an action for possession and nothing more. Damages become available only where the holdover is both wilful and not in good faith, and the statute joins those two limbs with an "and", so a resident who honestly believed the tenancy continued is outside it even if the belief was wrong. Good faith is defined in the Act as honesty in fact in the conduct of the transaction concerned, as shown by all the surrounding circumstances. Where both limbs are met the owner may recover the damages actually sustained plus reasonable attorney's fees; and the Act separately gives fees to the prevailing party in a private enforcement action, so a fee award does not by itself depend on bad faith.

Yes: a statute imposes the duty.

When it attaches: The duty sits in the Act's remedies-administration section rather than in the abandonment section, so it attaches whenever a party claims damages under the Act, not only when a resident abandons. The abandonment section then supplies the specific machinery: on abandonment the owner may re-rent at a fair rental, and a re-rental for a term beginning before the original agreement would have ended terminates that agreement on the day the new residency starts.

Burden of proof: no authority allocates it.

The standard: The statute states a duty and no standard. It says the aggrieved party has a duty to mitigate damages and stops there: the words reasonable efforts and commercially reasonable appear nowhere in it. The only standard-like wording in the Act is in the abandonment section, which says that on abandonment the owner may make reasonable efforts to rent the unit at a fair rental. Those two sections were enacted together in 1975, neither has ever been amended, and no New Mexico appellate court has reconciled the flat duty in one with the permissive language in the other. A landlord should read the duty as the operative rule, because a permission to re-rent is not a dispensation from a duty; but the tension is in the statute and a court has not resolved it.

No authority addresses a clause accelerating the remaining rent.

The lease may not waive the duty.

New Mexico imposes the duty by statute and does it in an unusual way: the Act's remedies section says the aggrieved party has a duty to mitigate damages. That is bilateral, so a resident suing an owner under the Act carries the same duty, and it is chapter-wide rather than tied to abandonment. Nothing states a standard, and nothing says who must prove that efforts were or were not made. No New Mexico appellate decision construes the section, and the official annotations printed under it carry no state case notes at all. Two cautions belong here. First, the abandonment section uses permissive language for the same subject and has never been squared with the duty. Second, New Mexico's leading appellate authority on re-letting states a no-duty rule and is often quoted as the state's answer, but it is a commercial-lease decision that never cites the residential statute, which does not reach commercial leases. For a dwelling the statutory duty governs. The lease cannot waive it, because the Act's anti-waiver clause bars any agreement to forego a right or remedy under the law, and no statute either bars or authorizes a clause accelerating the remaining rent.

No statute addresses a fee a landlord may charge for ending a lease early; the general damages rules govern.

No New Mexico statute authorizes, caps, or bars a fee for ending a residential lease early. There is no lease-break fee, no buy-out clause rule, no re-letting charge limit, and no liquidated-damages provision anywhere in the Act. The two penalties the Act does name both run against the owner rather than the resident: $250 to the resident for a deposit violation, and twice the monthly rent against an owner who brings a frivolous or bad-faith substantial-violation possession action. What New Mexico caps is everything except the exit: the late fee, cut in 2025 from 10 percent to 5 percent of the rent for each rental period in default and calculated on rent alone rather than on deposits, other fees, or utilities; the application screening fee, capped at $50 with a bar on charging any other fee to process an application; and any fee increase under an existing agreement, which now takes 60 days' written notice against the 30 days that a rent increase takes. Four things do the work a fee cap would do. The lease cannot make the resident give up a right or remedy. A court may limit an inequitable lease provision. An owner who deliberately uses a term known to be prohibited owes damages and fees. And since June 20, 2025 it is an unfair or deceptive trade practice, with that statute's own remedies behind it, for an owner to charge fees that are not included in the rental agreement. The state's administrative rules were consulted for the housing title, which contains nothing on rental fees or lease termination; the Act creates no agency and no rulemaking power, and leaves enforcement to private action.

Early-exit rights by ground: domestic violence and related grounds, no statute; military service beyond the federal act, state orders or National Guard duty are covered; death of the tenant, no statute; and other statutory grounds.

Domestic violence and related grounds: no statute gives a victim a right to end the lease early.

New Mexico gives a victim of domestic violence no statutory right to end a lease early. Nothing in the residential Act, the Family Violence Protection Act, or the crime-victim provisions of the criminal-procedure chapter lets a survivor terminate, and the words stalking, dating violence, human trafficking, domestic abuse, and safety plan appear nowhere in the property chapter. What the Act gives instead is a defense, and only inside an eviction the owner has already started. Where an owner terminates on three days' notice for a substantial violation, it is a defense that the resident is a victim of domestic violence; if the resident has filed for or secured a temporary domestic-violence restraining order arising from the incident behind the notice or from an earlier one, the writ of restitution may not issue at all. In every other case where domestic violence is raised as a defense, the court has discretion to evict the resident accused of the violation while allowing the tenancy of the remaining residents to continue undisturbed, so removal of the person responsible is a power the court holds inside the owner's own case, not something the survivor can require. That defense states no notice period, no documentation the resident may choose, and no release from rent. The Family Violence Protection Act lets a court grant a protected party sole possession of the residence or order the restrained party to provide temporary suitable housing, but that is an order against the abuser: it does not touch the lease, release the survivor from rent, or impose anything on the owner. There is no confidentiality duty and no protection against a landlord or a screening service characterizing the departure; the Act's only lock provision runs the opposite way, making it an unlawful act for the owner to plug, change, add, or remove a lock. Bills to create the right were introduced in 2019 and again in 2025 and both died in committee, and no bill was refiled in 2026.

Military service: State orders or National Guard duty are covered.

When the state rights attach: The state statute adopts the federal act rather than writing lease mechanics of its own, so a covered Guard member follows the federal notice and effective-date rules. Two duty statuses qualify: state active duty for 30 or more consecutive state duty days, and any federally funded duty performed in an operational role for homeland security under the federal statute governing that duty, with no day threshold on the second and with ordinary federally funded unit training, assembly, and drill expressly excluded. New Mexico adds no independent right for a spouse or dependent, no shorter deployment threshold, and no faster effective date.

New Mexico's landlord-tenant Act says nothing about military service at all. The state's addition to the federal Servicemembers Civil Relief Act sits in the military chapter instead: the rights, benefits, and protections of the federal act apply to a member of the National Guard of this state or of any other state or territory who is ordered to state active duty for 30 or more consecutive state duty days, or to any federally funded duty performed in an operational role for homeland security. Because the federal act's lease-termination right is one of those protections, a Guard member inside that class may end a residential lease on federal terms even though the orders are state orders the federal act would not reach on its own, and the reciprocity added in 2017 means another state's Guard member on New Mexico state active duty is covered too. Separately, and not a termination right, a member of the armed forces, the reserves, or the New Mexico National Guard who is deployed or on temporary duty outside the community for more than 30 days may suspend municipal or county services, public utilities, and regulated telecommunications service without penalty, on a four-part certification that includes owning the home or holding a lease that does not preclude suspension, and may reconnect on return without a reconnection fee.

Death of the tenant: No statute gives a right to end the lease on the tenant's death.

Other grounds: Three statutory grounds let a New Mexico resident end the agreement early. After a fire or casualty that substantially impairs enjoyment of the unit, the resident may vacate and then notify the owner in writing within seven days afterwards, and the agreement ends as of the date of vacating; the order of operations is unusual, because the resident moves out first and the notice back-dates the termination. Alternatively, where continued occupancy is lawful, the resident may vacate only the unusable part and pay proportionally reduced rent. Prepaid rent and any recoverable deposit come back, accounted as of the vacating date, and the resident stays liable for damage caused by the resident's own negligence. Second, where the owner makes an unlawful entry, makes a lawful entry in an unreasonable manner, or makes repeated demands for entry that have the effect of unreasonably harassing the resident, the resident may seek an injunction or terminate the agreement, and may recover damages and attorney's fees either way; no notice period attaches. Third, where the owner knowingly excludes or dispossesses the resident without a court order by any of seven listed means, including changing a lock, blocking an entrance, cutting off services or utilities, or any wilful act making the unit inaccessible or uninhabitable, the resident may abate the whole rent for each day possession is denied, recover civil penalties and damages, and either recover the premises or terminate. New Mexico has no care-facility, age or disability, job-transfer, foreclosure, or natural-disaster termination ground. Ending the agreement because the owner will not repair, and protection against a retaliatory non-renewal, are covered on the habitability page.

Absence for a stated period ends the tenancy by presumption. The absence period is 7 days.

New Mexico defines abandonment and gives it immediate effect, with no notice step and nothing for the resident to answer. Abandonment means absence of the resident from the dwelling, without notice to the owner, for more than seven continuous days, and only where that absence begins after rent is already delinquent. Both elements are needed: an unexplained absence while the rent is current is not abandonment, and a delinquency without an absence is not either. Seven days is among the shortest thresholds in the country. Once both are met the owner is entitled to take immediate possession, and must remove and store the resident's personal property for the periods the law provides. There is no notice of belief of abandonment, no rebuttal window, no waiting period, and no court order, which is what distinguishes New Mexico from the states that use a notice-and-response model. The tenancy itself is treated as ended only if the owner re-rents: a new residency beginning before the original agreement would have expired terminates the old agreement as of the day the new one starts. Absent a re-rental the agreement continues and the owner's claim for rent and damages survives, subject to the duty to mitigate. A separate rule gives the owner damages where the resident wilfully fails to give notice of an extended absence, but only where the rental agreement actually requires such a notice, and the owner may enter the unit at reasonable times during any absence longer than seven days. Surrender is a different concept, governed by the common law. What may be done with property left behind is covered separately from this page.

One section governs service of every written notice under the Act, including the termination notice, and it is built around receipt rather than a list of permitted methods. The general standard is that a person gives notice by taking steps reasonably calculated to inform the other in the ordinary course, whether or not the other actually learns of it. A written notice to the resident is received when it comes to the resident's attention, or when it is delivered in hand, or when it is mailed to the place the resident held out for receipt or, if none was named, to the resident's last known place of residence. A written notice to the owner is received when it is mailed or otherwise delivered at the business place through which the rental agreement was made, or at any place the owner holds out for receiving communications. Posting is permitted but never on its own: except for a nonpayment notice, a posted notice must be accompanied by first-class mail or by hand delivery to the resident, it must be affixed to a door by taping all sides or placed in a fixture or receptacle designed for notices or mail, and it must state the date it was posted, which then becomes the effective date of the notice.

Electronic delivery: the termination statute is silent on it.

What the notice must contain: A termination notice must be in writing, and it must name the date the count runs to: the periodic rental date for a month-to-month residency, or the termination date for a week-to-week one. A posted notice must also state the date it was posted. Beyond that the Act prescribes no form, no statement of grounds, no advisory language, and no citation of the statute. The courts add two content rules that are easy to miss: the notice must be definite enough to inform the tenant that the landlord wants the tenant to leave, and a notice bundled with an offer to stay at a higher rent is not a termination notice. The heavy content requirements the Act does contain, including the duty to specify the acts and omissions constituting a breach with dates and specific facts, belong to the for-cause notice and are covered on the eviction page.

Alternate address: The Act imposes a re-service duty that most states do not have. Where a required notice is mailed and comes back undeliverable, or where the last known address is the dwelling unit the resident has vacated, the owner must serve at least one additional notice if the resident has given the owner an alternative address. So a resident who leaves a forwarding address with the landlord gains a second, mandatory attempt at service, and a landlord who has one and ignores it after a returned mailing has not finished serving the notice.

The Uniform Owner-Resident Relations Act cites no federal statute anywhere in its termination machinery. The federal Servicemembers Civil Relief Act reaches New Mexico two ways: of its own force for federal military service, and by state adoption in the military chapter for National Guard members on qualifying state active duty or homeland-security duty. The federal Violence Against Women Act gives protections against eviction and denial in covered assisted housing and an emergency-transfer route, but it confers no right to end a lease early and reaches no private-market tenancy, and New Mexico has no state right behind it.

The federal CARES Act 30-day notice to vacate for covered properties, as read in this state's courts: no state appellate decision construes it. No New Mexico appellate decision construes the federal 30-day notice for covered dwellings. There is no standing court order or published trial-court practice on the point that a reader would meet either. The provision was never repealed, so a landlord of a covered dwelling should treat it as applying; New Mexico's own courts have simply not spoken. (Appellate picture read as of September 4, 2026.)

Mesilla Valley Mall Co. v. Crown Industries, 111 N.M. 663, 808 P.2d 633 (N.M. 1991) (Supreme Court of New Mexico; arose from a commercial lease; bears on the duty to re-let): Absent legal justification, a tenant who abandons occupancy before the lease expires remains liable for rent for the rest of the term, and under traditional common-law property rules the landlord is under no obligation to re-let to reduce that liability. The landlord may instead retake possession on the tenant's behalf and re-let for the tenant's account, or accept the tenant's offer to surrender, which ends the lease and leaves the tenant liable only for rent accrued before acceptance. The court found a surrender by operation of law where the landlord took the space back for its own benefit rather than the tenant's. This is a commercial retail lease and the decision neither cites nor applies the residential Act, which does not reach a commercial lease, so it is not authority that New Mexico dwellings carry no duty to mitigate.

WXI/Z Southwest Malls Real Estate Liability Co. v. Mueller, 2005-NMCA-046, 137 N.M. 343, 110 P.3d 1080 (New Mexico Court of Appeals; arose from a commercial lease; bears on the duty to re-let): Restating the earlier rule, the court said that unless a landlord accepts a tenant's surrender of the premises the landlord has no duty to mitigate damages during the term of the lease, and added that New Mexico courts have no discretion to relieve parties to a commercial lease of their contractual obligations. The dispute arose from a commercial shopping-mall lease and guaranty, so like the decision it restates it says nothing about the residential statutory duty.
