New Mexico Landlord-Tenant Law 2026: The Plain-English Guide
New Mexico sits in the middle of the landlord-friendliness spectrum, with a twist: it caps security deposits but gives you one of the sharpest eviction toolkits in the Southwest — 3-day notices for nonpayment and illegal activity, and no local rent control in force anywhere. The governing law is the Uniform Owner-Resident Relations Act, NMSA §§ 47-8-1 through 47-8-52.
Security deposits
- Capped at one month's rent for rental agreements of less than one year (§ 47-8-18(A)). For year-or-longer leases you may collect more, but then you must pay the tenant interest on the deposit each year at the passbook savings rate — which makes big deposits on long leases a bookkeeping headache most landlords skip.
- Return within 30 days after termination of the agreement or the tenant's move-out, whichever is later, with an itemized written list of any deductions (§ 47-8-18(C)–(D)).
- Allowed deductions: unpaid rent and utility costs owed, plus damages from the tenant's noncompliance with the agreement or statutory obligations. Normal wear and tear is not deductible.
- Brutal noncompliance penalty: miss the 30-day window and you don't just risk damages — you forfeit the right to withhold any portion of the deposit, forfeit the right to assert a counterclaim in the tenant's recovery action, forfeit the right to sue for damages to the property, and owe court costs and the tenant's reasonable attorney fees (§ 47-8-18(D)). Calendar this deadline the day notice is served.
- Practical habit: because the penalty forfeits your property-damage lawsuit rights — not just the deposit money — treat the 30-day deposit disposition as a litigation deadline, not an accounting task. Photograph the unit the day it empties, pull contractor quotes within a week, and mail the itemized statement by day 25 at the latest.

Rent rules
- No rent control: New Mexico has no statewide rent control, and no local rent caps are in force. Housing-cost politics resurface in Santa Fe every few sessions, so keep an eye on it — but as of 2026 there's nothing capping your increases.
- Rent-increase notice: on a month-to-month tenancy, give 30 days' written notice before a rent increase. On a fixed-term lease, give notice before the lease ends if the renewal will carry higher rent, so the tenant can decide whether to stay.
- Late fees capped at 5% of rent per rental period in default, and fees may be calculated only on rent — not on deposits, added fees, or utilities. You must give notice of the late fee no later than the last day of the next rental period after the default (§ 47-8-15(D)).
- No mandatory grace period for late rent as of 2026.

Eviction in New Mexico
New Mexico requires just cause for evictions, but the notice ladder is short and the process runs through magistrate court quickly — contested cases typically get heard within 7–10 days of service, with a $77 filing fee.
- Nonpayment: 3 days' written notice to pay the stated amount or vacate (§ 47-8-33(D)). The notice must state the amount owed and the deadline.
- Lease violations (noncompliance): 7 days' notice to remedy for a first violation — cure it within 7 days and the tenancy survives. If the same or substantially similar violation recurs within 6 months, the second notice is a 7-day unconditional notice to vacate — no cure offered (§ 47-8-33(A)–(B)).
- Substantial/illegal violations: 3 days' unconditional notice to quit — covers drug use or distribution, assault, criminal activity on the premises, and property damage (the statute's examples include damage over $1,000) (§ 47-8-33).
- No-cause month-to-month termination: 30 days' written notice before the next rental payment date (§ 47-8-37(B)). You cannot end a fixed-term lease early without legal cause, but you can always decline to renew and let it expire naturally.
- After the notice period: file a Petition by Owner for Restitution in magistrate court. Self-help — lockouts, utility shutoffs, seizing belongings — is illegal and will poison your case.
Document every violation with dates and photos; a well-papered 7-day notice is the cheapest eviction you'll ever do. Full process: how to evict a tenant.
- The 6-month repeat-violation rule is your friend: New Mexico lets a first offense be cured but a repeat within 6 months becomes a 7-day unconditional notice to quit. That means chronic-problem tenants remove themselves from cure protection — you just have to keep dated records of the first incident. Tenants who know you document the first violation reliably tend to correct course the first time.
Repairs and habitability
- You must keep the unit safe, sanitary, and habitable and maintain common areas, water, electricity, heating, and other essential services.
- 7-day repair clock: after the tenant gives you written notice of a problem, you have 7 days to fix it. Insist on written requests in your lease — verbal complaints create evidentiary mush.
- Rent abatement: if you miss the 7-day window on a qualifying condition, the tenant may abate rent — one-third of the prorated daily rent for each day the condition persists, or 100% of rent if the unit is uninhabitable and the tenant can't live there (§§ 47-8-27.1, 47-8-27.2). This is a real financial lever on tenants, so treat written repair notices as urgent.
- Log and respond same-day: keep a simple maintenance log (date received, date acknowledged, date resolved) for every written request. In a dispute, the log plus your receipts is what proves you met the 7-day clock — the tenant's abatement math starts the day you went silent. Our maintenance request playbook covers a workflow that keeps you inside the statute without living in reactive mode.
- Tenants may also terminate the lease, make the repairs and deduct the cost, or sue if habitability is materially impaired — after proper notice and your failure to act.
- Tenants' obligations: keep the unit clean, dispose of waste properly, do small maintenance, don't intentionally or negligently damage the property, and don't disturb the peace.
- Retaliation is prohibited.

Entry rights
- 24 hours' advance written notice before entering a unit, and you should try to accommodate the tenant's entry-time requests (§ 47-8-24(A)(1)).
- Emergency only for no-notice entry — fire, flood, gas leak, and the like (§ 47-8-24(B)).
- Harassment has teeth: a landlord who repeatedly enters without proper notice can be liable for landlord harassment. The tenant can get a court order barring your entry, recover damages, or terminate the rental agreement early without penalty (§ 47-8-24). One bad entry habit can cost you a whole tenancy.
- Schedule inspections, maintenance, and showings on a predictable rhythm with proper written notice, and this section never costs you a dime.
Discrimination
Federal Fair Housing Act protections apply, plus New Mexico's Human Rights Act (NMSA § 28-1-7), which protects the federal classes and adds ancestry, sexual orientation, and gender identity among others. New Mexico enforcement is active — apply screening criteria uniformly and keep records. See our fair housing guide and tenant screening walkthrough.
The bottom line
New Mexico is a strong rental state if you respect three numbers: 30 days to return deposits (with the harshest miss-the-deadline penalty of the three states here), 5% as your late-fee ceiling, and 24 hours written notice for every entry. In exchange you get a 3-day nonpayment notice, a 7-day cure-or-repeat-eviction ladder that rewards good documentation, and no rent control. The deposit rules are the danger zone — the cap plus the forfeiture penalty means deposit handling is where New Mexico landlords get burned. Handle deposits like a fiduciary and everything else here is smooth.
One last New Mexico tip for 2026: housing-policy bills keep surfacing in Santa Fe, including periodic attempts at local rent-control authority. Nothing is in force, but landlord associations and local news are worth a periodic check each session. In a state where the 5% late-fee cap and the one-month deposit cap are already fixed by statute, any new legislation will hit your operating margins directly — stay ahead of it rather than reading about it after it passes.
