New Mexico gives residents an unusually specific statutory rent-abatement remedy for qualifying repair conditions. Under NMSA 1978 § 47-8-27.2, after the required written notice and a seven-day remedy period, a resident may abate rent at a statutory rate tied to the condition: one-third of the pro-rata daily rent in qualifying cases, or one hundred percent where the dwelling is uninhabitable and the resident does not occupy it because of the condition.

That mechanism explains why the seven-day written notice is the most important document in New Mexico property management. The abatement is calculated from the date of the resident's notice, not from the day the seven days expire.

This guide covers the New Mexico landlord repair obligations in § 47-8-20, the resident remedies in §§ 47-8-27.1 and 47-8-27.2, the entry rules, the deposit forfeiture provision, and the retaliation bar that expressly protects a resident who abates rent. It also reflects the Laws 2025, ch. 122 amendments, effective 20 June 2025, which cut the late fee cap from ten percent to five, renumbered the civil penalty for self-help and retaliation within § 47-8-48 while adding a new penalty for unauthorised screening fees, and created four new sections on applicant screening.

One terminology note. New Mexico does not use "landlord" and "tenant" in its statute. It uses owner and resident, under the Uniform Owner-Resident Relations Act, §§ 47-8-1 to 47-8-52.

Quick Reference: New Mexico Repair Duties and Resident Remedies

New Mexico Has No Implied Warranty of Habitability. It Has § 47-8-20.

This shapes everything else, and most guides get it backwards.

In T.W.I.W., Inc. v. Rhudy, 96 N.M. 354, 630 P.2d 753 (1981), the New Mexico Supreme Court addressed a tenant's contention that an implied warranty of habitability was in effect. The court had previously held there was no implied warranty of habitability in New Mexico, and the matter was remanded for determination of the applicability of § 47-8-20, which the court noted encompassed the issue and was adopted after that holding.

The repair duty is therefore statutory, not judicial.

Section 47-8-20(A) sets out six core owner obligations. The owner shall:

1. Substantially comply with requirements of the applicable minimum housing codes materially affecting health and safety;

2. Make repairs and do whatever is necessary to put and keep the premises in a safe condition as provided by applicable law and rules and regulations under § 47-8-23;

3. Keep common areas of the premises in a safe condition;

4. Maintain in good and safe working order and condition electrical, plumbing, sanitary, heating, ventilating, air conditioning and other facilities and appliances, including elevators, supplied or required to be supplied by the owner;

5. Provide and maintain appropriate receptacles and conveniences for the removal of ashes, garbage, rubbish and other waste, and arrange for their removal; and

6. Supply running water and a reasonable amount of hot water at all times and reasonable heat, except where the building is not required by law to be so equipped or where heat or hot water is generated by an installation within the resident's exclusive control supplied by a direct public utility connection.

The section contains further obligations in subsections (B) through (G), so those six are the core repair duties rather than the whole of § 47-8-20.

Note paragraph (2). New Mexico says "safe condition," not the "fit and habitable" formula used in most URLTA states. That is a deliberate difference worth using precisely.

Where a code applies, the code sets the ceiling. Section 47-8-20(B) provides that if a minimum housing code applies to the premises, the owner's maximum duty under the section is determined by paragraph (A)(1). T.W.I.W. explains the structure: paragraphs (A)(2) through (A)(6) remain as minimum standards where there is no applicable code, and where a code applies the court would never reach (A)(6) because (A)(1) would apply. The same case places the burden on the owner to show that a law exists exempting them from providing reasonable heat.

One duty most owners miss. Section 47-8-20(G) requires the owner to provide a written rental agreement to each resident prior to the beginning of occupancy. That is a statutory obligation, which is a good reason to hold lease issuance and delivery dates on the tenancy record through contracts and renewals.

Section 47-8-20(B) also states that the obligations imposed are not intended to change existing tort law. Separate negligence duties can arise, as in Calkins v. Cox Estates, 110 N.M. 59, 792 P.2d 36 (1990), where a landlord owed a duty to keep a fence around a common playground area in reasonably safe condition.

Written Notice Is the Gate for the Statutory Repair Remedies

For the termination and rent-abatement routes under §§ 47-8-27.1 and 47-8-27.2, the resident must provide the required written notice identifying the breach or the conditions needing repair.

Kepler v. Covarrubia, 91 N.M. 443, 575 P.2d 952 (1978), confirms that actual knowledge alone does not substitute. Where the resident did not give written notice of deficiencies, the resident was not eligible for abatement, and the trial court erred by abating after finding only that the landowner had actual notice.

That is meaningful protection for owners. Two provisions can remove it.

Section 47-8-19(D). The owner must disclose in writing, at or before commencement of the residency, the name, address and telephone number of the person authorised to manage the premises and of an owner or person authorised to act for the owner for service of process and for receiving notices and demands. Failure to comply relieves the resident from the obligation to provide notice to the owner as required by the Act.

Read that against Kepler. A missing or stale disclosure can surrender the very notice requirement that would otherwise defeat an abatement claim. Section 47-8-19(B) requires the information to be kept current and makes it enforceable against any successor, owner or manager, which matters on every acquisition and management transition.

Section 47-8-13(D) governs how the owner serves notices on the resident. These service rules matter primarily when the owner is serving a statutory notice on the resident. They should not be confused with the separate question of how a resident gives repair notice to the owner.

Notice to a resident for nonpayment of rent is effective only when hand delivered, mailed, or posted on an exterior door. In all other cases where written notice to the resident is required, even where there is posting, there must also be a mailing by first class mail or hand delivery. The date of posting must be included and constitutes the effective date, and a posted notice must be affixed to a door by taping all sides or placed in a fixture or receptacle designed for notices or mail. Under § 47-8-13(F), where notice is mailed but returned undeliverable, or the last known address is the vacated unit, the owner shall serve at least one additional notice if the resident provided an alternative address.

The Two Resident Routes: Terminate or Abate

Route one: terminate under § 47-8-27.1(A)(1)

Where there is material noncompliance by the owner with the rental agreement, or noncompliance with the Act materially affecting health and safety, the resident delivers written notice specifying the acts and omissions constituting the breach. The notice states that the agreement terminates on a date not less than seven days after receipt if a reasonable attempt to remedy the breach is not made in seven days.

The standard is a reasonable attempt to adequately remedy, not completion. If the owner makes a reasonable attempt before the date specified, the agreement does not terminate. For a repair with a parts lead time or a specialist contractor, that distinction decides whether the tenancy survives, and it makes dated work orders, contractor communications and scheduling records the evidence that matters. Service history held against the unit through utility and asset management does more work here than a maintenance inbox.

If terminated and possession restored, the owner must return the balance of prepaid rent and deposit to which the resident is entitled.

Route two: abate under § 47-8-27.2

If there is a violation of § 47-8-20(A), other than a failure or defect in an amenity, the resident gives written notice of the conditions needing repair. If the owner does not remedy those conditions within seven days of the notice, the resident is entitled to abate:

• One-third of the pro-rata daily rent for each day from the date the resident notified the owner, through the day the conditions are remedied. If the conditions continue into a subsequent rental period, the resident may abate at the same rate for each day they are not remedied.

• One hundred percent of the rent for each day from the date of notice until the breach is cured

  if the dwelling is uninhabitable and the resident does not inhabit the dwelling unit as a result of the condition.

Four features decide how this plays out.

• The seven-day period does not erase the notice-date calculation. If the owner fails to remedy within seven days, the one-third abatement is calculated from the date of the resident's notice. A condition remedied inside the seven days does not trigger the statutory abatement route, while an uncured condition can produce an abatement calculated back to the notice date.

• The 100 percent rate has two conditions, not one. The dwelling must be uninhabitable and the resident must not be inhabiting it as a result of the condition. In Hedicke v. Gunville, 2003-NMCA-032, 133 N.M. 335, 62 P.3d 1217, tenants had no right to abate where the property was not uninhabitable, and their retaliation claim failed because they lived on the premises continuously and the premises were not uninhabitable for any of the seventeen months in which they had not paid rent.

• Amenities are carved out entirely. Section 47-8-27.2(E) states that nothing in the section entitles the resident to abate for the unavailability of an amenity, and § 47-8-3 defines an amenity as a facility, appurtenance or area supplied by the owner the absence of which would not materially affect the health and safety of the resident or the habitability of the dwelling unit. A closed pool, gym or clubhouse is an amenity question. A failed water heater is not.

• Subsidised housing is measured on the whole rent. Under § 47-8-27.2(C), where rent is subsidised in whole or part, the abatement limitation of one month's rent means the total monthly rent paid for the dwelling, not the resident's portion. Either the payer or the resident may authorise the remedy and abate.
  
  

  Section 47-8-27.2(D) preserves the court's discretion to apply equitable abatement, and § 47-8-4 lists equitable abatement among the principles supplementing the Act.

The election rule, and why it resets

Section 47-8-27.1(D) requires an election: a resident proceeding under the termination route shall not proceed under the abatement route in the same rental period for the same violation, and vice versa. But the resident may proceed under the other route for a subsequent violation, or for the same violation occurring in subsequent rental periods.

An unresolved condition therefore does not lock the resident into one remedy. It resets each month.

Damages and injunctive relief sit on top. Section 47-8-27.1(C) allows the resident to recover damages and obtain injunctive relief for any material noncompliance, expressly in addition to the subsection (A) rights.

Two limits that protect the owner

• Resident-caused conditions. Under § 47-8-27.1(B), the rights do not arise if the condition was caused by the deliberate or negligent act or omission of the resident, a family member, or another person on the premises with the resident's consent.

• Circumstances beyond the owner's control. Where the noncompliance results solely from circumstances beyond the owner's control, the resident is limited to the remedies in paragraph (1) or (2) and is not entitled to an action for damages or injunctive relief.

• Weekends extend the clock. Section 47-8-27.1(E) provides that when the last day for remedying a breach falls on a weekend or federal holiday, the period extends to the next day that is not a weekend or federal holiday. Section 47-8-33(H) applies the same rule to owner-side notices.

Shifting Repair Duties by Agreement

Single family residences, § 47-8-20(C). The parties may agree that the resident perform the duties in paragraphs (A)(5) and (A)(6), waste removal and water, hot water and heat, and also specified repairs, maintenance tasks, alterations and remodelling, only if the transaction is in writing, for consideration, entered into in good faith and not for the purpose of evading the owner's obligations.

Other dwelling units, § 47-8-20(D). The parties may agree that the resident perform specified repairs, maintenance tasks, alterations or remodelling only if the agreement is in good faith and not to evade the owner's obligations, is set forth in a separate writing signed by the parties and supported by consideration, and does not diminish or affect the owner's obligation to other residents.

And here is the provision to read twice. Section 47-8-20(E) states that notwithstanding any provision of the section, an owner may arrange with a resident to perform the owner's obligations, but any such arrangement will not serve to diminish the owner's obligations, nor shall the resident's failure to perform them serve as a basis for eviction or in any way be considered a material breach.

Duty-shifting in New Mexico reallocates work, not liability.

Entry: 24 Hours, With a Repair Exception Most Owners Miss

Section 47-8-24(A)(1) requires that, unless otherwise agreed, the owner may enter only after giving twenty-four hours written notification of the intent to enter, the purpose for entry, and the date and reasonable estimate of the time frame of the entry. Not just twenty-four hours. Purpose, date and a time window.

The exception is genuinely useful. Section 47-8-24(A)(2) provides that the subsection does not apply to entry to perform repairs or services within seven days of a request by the resident, or where the owner is accompanied by a public official conducting an inspection or a cable television, electric, gas or telephone company representative.

Read that alongside § 47-8-27.2. A resident's written repair notice both starts the seven-day abatement clock and opens a seven-day window in which the twenty-four hour notice rule does not apply to repair visits. The statute is built to let you move quickly on the thing you have just been told about.

Section 47-8-24(A)(3) adds a reciprocal duty: where the resident gives reasonable prior notice and alternate times or dates, and it is practicable or will not result in economic detriment, the owner shall attempt to reasonably accommodate the alternate time.

Emergencies allow entry without consent under (B). The owner shall not abuse the right of access under (C). Under (E), (F) and § 47-8-38, refusal of lawful access lets the owner seek injunctive relief or terminate with damages, fees and costs, while unlawful entry, lawful entry in an unreasonable manner, or repeated harassing demands let the resident seek injunctive relief or terminate with damages and reasonable attorney's fees.

Deposits: A 30-Day Accounting Rule With Real Teeth

Amounts. The owner may demand a reasonable deposit to be applied to recover damages caused to the premises. On an agreement of duration less than one year, the owner shall not demand or receive a deposit in excess of one month's rent.

"Reasonable" is enforced. In Hedicke v. Gunville, the court noted that § 47-8-18(A) required the deposit to be reasonable, and that no reasonable jury could have found a sum nearly thirty-two times the monthly rent to be merely a security deposit.

The interest provision, and a practical problem with it. On an annual rental agreement, if the deposit exceeds one month's rent, § 47-8-18(A)(1) requires the owner to pay the resident annually an interest equal to "the passbook interest permitted to savings and loan associations in this state by the federal home loan bank board."

The statutory duty stands. The reference does not. The Federal Home Loan Bank Board was abolished in 1989, so the body the statute points to for the rate has not existed for decades and the provision does not supply an ascertainable current figure. The practical consequence for a New Mexico owner is straightforward: either keep the deposit at or below one month's rent on annual agreements and avoid the question, or take New Mexico counsel on what rate to apply before charging more.

The accounting rule. No deposit shall be retained to cover normal wear and tear, which § 47-8-3 defines as deterioration based on the intended use, without negligence, carelessness, accident, abuse or intentional damage, and which expressly notes that uncleanliness does not constitute normal wear and tear. Where actual cause exists to retain any portion, § 47-8-18(C) requires the owner to provide an itemised written list of the deductions and the balance within thirty days of the date of termination of the rental agreement or resident departure, whichever is later. Mailing the statement and any payment to the last known address is compliance.

The forfeiture. Under § 47-8-18(D), an owner who fails to provide the required written statement of deductions and the balance within the statutory period forfeits the right to withhold any portion of the deposit, forfeits the right to assert a counterclaim in an action to recover the deposit, is liable for court costs and reasonable attorneys' fees, and forfeits the right to bring an independent action for damages to the rental property.

The New Mexico Supreme Court applied that in Bruce v. Attaway, 1996-NMSC-030, 121 N.M. 755, 918 P.2d 341: an owner who does not provide an itemised listing within thirty days of vacancy forfeits any right to withhold and to file suit for the alleged damages. In Garcia v. Thong, 119 N.M. 704, 895 P.2d 226 (1995), a landlord who failed to give an itemised account forfeited the deposit and the right to recover additional damages, and owed attorney fees.

The rule should not be overstated. The forfeiture is triggered by failure to comply with the accounting requirement, not by the mere fact that a particular item was not deducted. In Stodgell v. Weissman, 2025-NMCA-003, cert. denied, the New Mexico Court of Appeals addressed whether an owner who timely complied with § 47-8-18 may later pursue property damage that was not previously identified and deducted, and the critical distinction is between timely compliance with the deposit-accounting requirement and failure to comply with it.

The practical conclusion is the same either way: calendar the thirty days from termination or departure, whichever is later, and produce the itemised statement. That is what makes a dated condition record at both ends of the tenancy worth having, which is what move-in and move-out management is designed to produce.

Bad faith adds a penalty. Section 47-8-18(E) imposes a civil penalty of $250 payable to the resident where the owner in bad faith retains a deposit in violation of the section.

One narrow relief. Bruce v. Attaway records that a landlord was entitled to apply the deposit to unpaid rent without sending a written itemisation where the tenant failed to give the thirty days' notice of intent to terminate required by § 47-8-37.

Rent, Late Fees and the Abatement Collision

Late fees are now capped at five percent. Under § 47-8-15(D), as amended by Laws 2025, ch. 122 effective 20 June 2025, if the rental agreement provides for a late fee and the resident does not pay rent as required, the owner may charge no more than five percent of the rent for each rental period in which the resident is in default. Late fees shall be calculated only based on rent, and rent calculations to determine late fees shall not include deposits, additional fees or utilities. The owner must also provide notice of the late fee charged no later than the last day of the next rental period immediately following the period in which the default occurred.

Any New Mexico lease, ledger configuration or late fee automation built on the old ten percent figure is now out of compliance, and any calculation that includes utilities or other fees in the base is exposed.

Rent increases require thirty days. Section 47-8-15(F) requires written notice of a proposed increase at least thirty days before the periodic rental date in a month-to-month residency, or at least thirty days before the end of the term in a fixed term residency.

Payments cannot be reallocated. Under § 47-8-15(G), unless agreed in writing, a resident's payment of rent may not be allocated to any deposits or damages.

That matters directly in an abatement dispute. Section 47-8-33(E) provides that in a court action for possession for nonpayment where the resident disputes the amount owed because the resident has abated rent under § 47-8-27.2 or § 47-8-4, or because the owner has allocated rent paid as payment for damages, then if the owner prevails the court shall enter a writ of restitution conditioned upon the right of the resident to remedy within three days of entry of judgment. If satisfied within three days the writ is dismissed; if not, the owner may execute without further order.

A disputed abatement therefore changes the shape of the judgment, not just the defence. Because the fight is about which period the money applied to, rent collection and payment records tied to specific rental periods make an abatement dispute a reconciliation rather than a reconstruction.

New in 2025: Applicant Screening Rules

Laws 2025, ch. 122 also added four new sections that sit ahead of the tenancy: § 47-8-19.1 owner disclosure to applicants, § 47-8-19.2 dwelling unit applicant screening fee and prohibited fees, § 47-8-19.3 background checks, and § 47-8-19.4 notice of fee changes required. The same act added definitions of "applicant" and "screening fee" to § 47-8-3.

Section 47-8-19.2 caps a screening fee at fifty dollars to cover the cost of obtaining information about the applicant, including a consumer credit report, reference check or screening service, subject to conditions including written or digital notice of the fee and the applicant's written agreement to pay it. And under § 47-8-48(B), an owner who charges an unauthorised screening fee is liable for $250 and must return all fees paid by the applicant.

These are screening rules rather than repair rules, so they sit outside the scope of this guide, but any New Mexico portfolio should read §§ 47-8-19.1 to 47-8-19.4 in full before its next leasing cycle.

Self-Help Is Priced Three Ways

Under § 47-8-36(A), except in case of abandonment, surrender or as otherwise permitted, an owner or anyone acting on their behalf shall not knowingly exclude, remove, threaten or attempt to remove or dispossess a resident without a court order by: fraud; plugging, changing, adding or removing any lock or latching device; blocking any entrance; interfering with services or normal and necessary utilities including electricity, gas, hot or cold water, plumbing, heat or telephone service; removing the resident's personal property from the dwelling unit or premises; removing or incapacitating appliances or fixtures except for making necessary and legitimate repairs; or any willful act rendering the dwelling unit or personal property inaccessible or uninhabitable.

The section expressly does not impose a duty on the owner to make utility payments or prevent interruptions resulting from the resident's own nonpayment, and under § 47-8-36(B) it does not apply where the owner temporarily interferes with possession while making legitimate repairs or inspections as provided in the Act.

The consequences stack. Under § 47-8-36(C) the resident may abate one hundred percent of the rent for each day in which they are denied possession for any portion of the day, or each day the owner caused termination or diminishment of any service for any portion of the day; is entitled to civil penalties; may seek restitution or terminate; and is entitled to damages. Section 47-8-48(C) makes an owner who violates § 47-8-36 or § 47-8-39 liable for two times the amount of the monthly rent.

Section 47-8-36.1 also abolishes the landlord's lien on a dwelling unit to which the Act applies, though nothing prevents levy and execution on a judgment for rent or damages.

Retaliation Expressly Covers Abatement

Section 47-8-39 is broader than most state retaliation statutes and is written with repair disputes in mind.

An owner may not retaliate against a resident who is in compliance with the rental agreement and not otherwise in violation of the Act by increasing rent, decreasing services, or bringing or threatening to bring an action for possession because the resident has within the previous six months:

1. Complained to a government agency responsible for enforcing a minimum building or housing code of a violation materially affecting health and safety;

2. Organised or become a member of a residents' union, association or similar organisation;

3. Acted in good faith to exercise rights under the Act, including where the resident makes a written request or complaint to the owner to make repairs to comply with § 47-8-20;

4. Made a fair housing complaint to a government agency;

5. Prevailed in a lawsuit, or has one pending against the owner relating to the residency;

6. Testified on behalf of another resident; or

7. Abated rent in accordance with § 47-8-27.1 or § 47-8-27.2.

Paragraphs (3) and (7) are the ones to notice. A written repair request is itself a protected act, and so is abating rent. Under subsection (B), a violation entitles the resident to the remedies provided in § 47-8-48 and is a defence in any action for possession. For an owner who violates § 47-8-39, § 47-8-48(C) provides liability for two times the amount of the monthly rent.

Section 47-8-40(A) preserves the owner's ability to bring an action for possession notwithstanding the retaliation bar where the code violation was caused primarily by lack of reasonable care by the resident or someone on the premises with their consent; the resident is in default in rent; there is a material noncompliance that would otherwise give rise to a right to terminate; the resident knowingly commits or consents to a substantial violation; or compliance with the code requires alteration, remodelling or demolition depriving the resident of use of the unit. Under § 47-8-40(B), maintaining such an action does not release the owner from liability under § 47-8-20.

Two cases mark the boundary. In Casa Blanca Mobile Home Park v. Hill, 1998-NMCA-094, 125 N.M. 465, 963 P.2d 542, an action for possession motivated by retaliation for a resident's complaints about noisy neighbours was not barred, because no specific provision of the Act gave a resident the right to complain about noisy neighbours or required the owner to keep residents from being too noisy. And in Hedicke, a retaliation claim tied to abatement failed because the residents were not entitled to abate in the first place.

The protection attaches to acts the Act actually recognises. Complaints under § 47-8-20 are protected. Complaints about matters outside the Act may not be.

If It Reaches Court

Owner-side notice for resident breach. Under § 47-8-33(A), on noncompliance with § 47-8-22 materially affecting health and safety or an initial material noncompliance, the owner delivers written notice specifying the acts and omissions, including the dates and specific facts describing the nature of the alleged breach, stating the agreement terminates on a date not less than seven days after receipt if not remedied in seven days. Under (B), a second material noncompliance within six months supports a non-curable seven-day termination notice, and under (C) the initial notice must state that consequence and must be given within thirty days of the breach or knowledge of it. Nonpayment is a three-day notice under (D), and tender of the full amount in the manner stated in the notice before expiry bars the action.

Section 47-8-33(G) is a trap worth naming. In a judicial action to enforce a remedy for which prior written notice is required, relief may be granted only upon the grounds set forth in the written notice served.

The petition and the hearing. Section 47-8-42 requires a petition for restitution stating the facts with particularity, a reasonably accurate description of the premises, and the requisite compliance with the notice provisions of the Act. Under § 47-8-43(A)(1), trial on an owner's action for possession is set not less than seven nor more than ten days after service of summons, with a continuance of up to seven days on good cause. Where the resident brings the possession action, trial is set not less than three nor more than five days after service.

Counterclaims. Under § 47-8-30(A), the resident may counterclaim for any amount recoverable under the agreement or the Act, provided the resident is responsible for paying the rent specified in the agreement during the period of possession.

The writ. Section 47-8-46(A) directs the sheriff to restore possession on a date not less than three nor more than seven days after entry of judgment on an owner's petition. On a resident's petition, § 47-8-46(B) requires restoration within twenty-four hours.

Fees run both ways. Section 47-8-48(A) entitles the prevailing party to reasonable attorneys' fees and court costs. In a state where a resident can recover fees for a deposit failure, a retaliation finding, an unlawful entry or a self-help violation, that provision is a significant multiplier on procedural mistakes.

Managers running multi-state portfolios will notice how differently this is built from Ohio's eviction process, which front-loads a three-day notice with prescribed statutory language, or Georgia's dispossessory proceedings, which require a demand for possession but no statutory notice period. New Mexico's distinguishing feature is not the eviction timeline. It is that the resident has a statutory rent-abatement remedy that can be invoked before any court proceeding.

Common Mistakes Property Managers Make in New Mexico

1. Treating the seven days as a period excluded from the calculation. If the condition is not remedied in seven days, abatement is calculated from the date of the notice.

2. Waiting to complete the repair. Section 47-8-27.1(A)(1) asks whether a reasonable attempt to adequately remedy was made within seven days.

3. Failing to date and file the resident's written notice. It is the trigger for both clocks and the anchor for any abatement calculation.

4. Letting the § 47-8-19 disclosure go stale. Failure to comply relieves the resident of the obligation to give notice at all.

5. Serving a non-rent notice on a resident by posting alone. Section 47-8-13(D) requires posting plus mailing or hand delivery for owner notices other than nonpayment.

6. Omitting the posting date from the notice. It must be included and is the effective date.

7. Not re-serving after an undeliverable mailing where the resident gave an alternative address, contrary to § 47-8-13(F).

8. Conceding 100 percent abatement where the resident is still living there. The rate requires uninhabitability and non-occupancy.

9. Treating an amenity outage as abatable. Section 47-8-27.2(E) excludes amenities.

10. Assuming the resident is locked into one remedy. The election applies per rental period per violation.

11. Relying on a duty-shift agreement. Section 47-8-20(E) says the arrangement does not diminish the owner's obligations and the resident's failure to perform is not a basis for eviction.

12. Shifting duties without separate writing and consideration where the unit is not a single family residence.

13. Giving 24-hour entry notice without a purpose, date and time estimate, contrary to § 47-8-24(A)(1).

14. Not using the seven-day repair window in § 47-8-24(A)(2) after a resident's request.

15. Taking more than one month's rent as a deposit on a term under a year.

16. Taking more than one month's rent on an annual agreement without addressing the interest duty. Section 47-8-18(A)(1) requires annual interest, but the federal rate-setting body it names no longer exists, so take advice before exceeding one month.

17. Withholding for uncleanliness while calling it wear and tear. Section 47-8-3 says uncleanliness is not normal wear and tear, so itemise it properly.

18. Missing the statutory deposit-accounting deadline. Failure to provide the required statement and balance within the applicable period can forfeit the right to withhold the deposit, assert a counterclaim or bring an independent property-damage action, while exposing the owner to court costs and reasonable attorneys' fees.

19. Charging a late fee above five percent, calculating the fee on deposits, additional fees or utilities, or failing to give notice by the end of the next rental period. The cap dropped from ten percent to five percent on 20 June 2025.

20. Allocating a rent payment to deposits or damages without written agreement, contrary to § 47-8-15(G).

21. Changing a lock or interrupting a utility. One hundred percent daily abatement, restitution or termination, damages, and two times the monthly rent under § 47-8-48(C).

22. Raising rent or filing for possession within six months of a written repair request or an abatement. Both are expressly protected acts.

23. Pleading a ground not stated in the notice, contrary to § 47-8-33(G).

24. Charging an unauthorised screening fee. Section 47-8-48(B) makes the owner liable for $250 and requires return of all fees paid by the applicant.

Records That Decide New Mexico Repair Disputes

New Mexico is unusual in that the resident can act on their own before any court sees the file. That makes your records the only contemporaneous account of what happened and when.

Six categories are worth keeping in a centralised system.

The date each written repair notice was received, because it sets the abatement start date and the seven-day deadline simultaneously. The date and nature of your response, because the test is a reasonable attempt to adequately remedy, not completion. The current § 47-8-19 disclosure and the date it was provided, since a stale disclosure can remove the resident's notice obligation. Notice service records showing method, posting date and any re-service after an undeliverable mailing. A period-by-period rent ledger showing what was received and how it was applied, because abatement disputes are arguments about allocation, and because the five percent late fee must be calculated on rent alone. And the deposit sequence, with the termination or departure date, the thirty-day deadline, and the itemised list.

Because the notice sequence has steps that must happen in order and cannot be reconstructed later, this is a strong case for running it through workflow customization rather than as an ad hoc task, and for surfacing every open repair notice with its seven-day date and every deposit approaching its thirty-day deadline through dashboards and reports.

Conclusion

New Mexico's repair framework is statutory from top to bottom. There is no implied warranty of habitability, and T.W.I.W. v. Rhudy confirms the duty lives in § 47-8-20 instead: six core obligations, with the applicable minimum housing code setting the ceiling where one exists, and with "safe condition" rather than "fit and habitable" as the operative phrase.

The statutory repair remedies run on the resident's written notice. Kepler v. Covarrubia holds that actual knowledge alone did not substitute for the written notice required for abatement, which protects owners unless a stale § 47-8-19 disclosure has removed the notice requirement altogether.

If the owner does not make the required reasonable attempt to remedy within seven days, the resident may terminate under § 47-8-27.1 or, if the requirements of § 47-8-27.2 are satisfied, abate rent at one-third of the pro-rata daily rent, or one hundred percent where the dwelling is uninhabitable and unoccupied. The abatement is calculated from the date of the notice, amenities are excluded, and the choice of remedy resets each rental period.

Around that core sit provisions that punish procedural error rather than bad maintenance. A missed deposit accounting forfeits the deposit, the counterclaim and the independent damages action. A lockout or utility interruption costs full daily abatement plus two times the monthly rent under § 47-8-48(C). A rent increase or possession action within six months of a written repair request or an abatement is presumptively retaliatory. And the prevailing party takes fees.

The financial rules also changed recently. Since 20 June 2025, New Mexico has capped residential late fees at five percent of rent, excluding deposits, additional fees and utilities from the calculation, while the same act amended § 47-8-48, moving the self-help and retaliation penalty to subsection (C) and adding a new penalty for unauthorised screening fees, and created new applicant screening sections at §§ 47-8-19.1 to 47-8-19.4.

The operating discipline is short. Date every written notice the day it arrives. Respond inside seven days and record the attempt rather than waiting for completion. Keep the § 47-8-19 disclosure current. Serve non-rent notices by posting and mailing, with the posting date on the face. Recalculate your late fees to five percent of rent alone. Calendar the thirty-day deposit deadline the day the resident departs. And never touch a lock or a utility.

The Uniform Owner-Resident Relations Act at NMSA 1978 §§ 47-8-1 to 47-8-52 was amended by Laws 2025, ch. 122, effective 20 June 2025, which reduced the late fee cap, amended § 47-8-48 including the civil penalty provisions applicable to self-help and retaliation, and added §§ 47-8-19.1 to 47-8-19.4. Mobile home park lot tenancies are governed by the Mobile Home Park Act at NMSA 1978 § 47-10-1 and following, which can prevail over the Uniform Owner-Resident Relations Act where the two conflict, as in Green Valley Mobile Home Park v. Mulvaney. Verify the current statutory text before acting and consult a licensed New Mexico attorney on a specific matter.

Frequently Asked Questions

Q1. Does New Mexico have an implied warranty of habitability?
No. In T.W.I.W., Inc. v. Rhudy the New Mexico Supreme Court noted it had held there was no implied warranty of habitability in New Mexico, and that § 47-8-20, adopted afterwards, encompasses the issue. The repair duty is statutory.

Q2. What repairs is a New Mexico landlord required to make?
Under § 47-8-20(A), the owner must substantially comply with applicable minimum housing codes materially affecting health and safety, make repairs and keep the premises in a safe condition, keep common areas safe, maintain electrical, plumbing, sanitary, heating, ventilating, air conditioning and other facilities and appliances including elevators, provide waste receptacles and arrange removal, and supply running water, a reasonable amount of hot water and reasonable heat.

Q3. How long does a New Mexico landlord have to make repairs?
Seven days from the resident's written notice. Under § 47-8-27.1 the agreement can terminate if a reasonable attempt to remedy is not made within seven days, and under § 47-8-27.2 the resident may abate rent if the condition is not remedied within seven days of the notice.

Q4. Can a tenant withhold rent in New Mexico?
A resident may abate rent, which is different from withholding. Under § 47-8-27.2 the resident may abate one-third of the pro-rata daily rent per day, or one hundred percent per day where the dwelling is uninhabitable and the resident does not inhabit it.

Q5. Does the seven-day repair period mean rent abatement starts on the eighth day?
No. Under § 47-8-27.2(A), if the owner does not remedy the qualifying conditions within seven days of the resident's notice, the one-third abatement is calculated for each qualifying day from the date of the resident's notice through the date the conditions are remedied. The seven days functions as the remedy period, not as a period excluded from the calculation.

Q6. Does the tenant have to give written notice first?
Yes, for the statutory repair remedies. In Kepler v. Covarrubia the court held that a resident who did not give written notice was not eligible for abatement, and that the trial court erred by abating on a finding of actual notice alone. The exception is § 47-8-19(D): if the owner has not made the required disclosure of manager and owner details, the resident is relieved of the obligation to give notice.

Q7. Can a tenant abate rent because the pool or gym is closed?
No. Section 47-8-27.2(E) states that nothing in the section entitles the resident to abate for the unavailability of an amenity, and § 47-8-3 defines an amenity as something whose absence would not materially affect health and safety or habitability.

Q8. Can a tenant both abate and terminate?
Not for the same violation in the same rental period. Section 47-8-27.1(D) requires an election, but the resident may use the other route for a subsequent violation or for the same violation in a later rental period. Damages and injunctive relief under § 47-8-27.1(C) are available in addition.

Q9. How much notice must a New Mexico landlord give before entering?
Twenty-four hours' written notification stating the intent to enter, the purpose, and the date and a reasonable estimate of the time frame, under § 47-8-24(A)(1). That does not apply to repairs or services within seven days of a resident's request, or where the owner is accompanied by a public official conducting an inspection or a utility or cable representative.

Q10. How much can a New Mexico landlord charge as a deposit?
On a rental agreement of less than one year, no more than one month's rent. On an annual agreement, more is permitted but § 47-8-18(A)(1) then requires the owner to pay the resident annual interest. The deposit must in all cases be reasonable.
