New Mexico Security Deposit Law: Return Deadline, Limits, and How to Get It Back

In New Mexico, a landlord generally has 30 days after a tenancy ends to return your security deposit, and if any money is kept, the landlord must give you a written, itemized statement of the deductions within that same window. For a rental agreement of less than one year, the deposit is capped at one month's rent. These rules come from New Mexico's landlord-tenant statute, the Uniform Owner-Resident Relations Act (commonly cited as NMSA 1978, Sections 47-8-1 through 47-8-52, with deposits addressed in Section 47-8-18). Because statutes are amended and some cities have their own rules, confirm the current section before you rely on a specific figure.

How much a New Mexico landlord can charge

New Mexico is one of the states that actually caps deposits, but the cap depends on the length of your lease:

• For a rental agreement of less than one year, the security deposit may not be more than one month's rent.
• For a lease of one year or longer, there is no fixed dollar cap, but if the landlord charges more than one month's rent, the landlord must pay you annual interest on the deposit at a rate equal to the passbook savings interest rate.

This deposit is separate from rent. A landlord generally cannot relabel the last month's rent as a "non-refundable deposit" to dodge these limits, though pet fees and similar charges are sometimes treated differently in the lease.

The 30-day return deadline and itemized statement

After you move out and the tenancy ends, the landlord has 30 days to either return the full deposit or send you a written itemized list of what was deducted and why, along with any remaining balance. The clock generally runs from the date the rental agreement terminates and you give up possession.

• If the landlord keeps part or all of the deposit, the written itemized statement is mandatory, not optional.
• Send the landlord your forwarding address in writing so there is a record of where the refund and statement should go.
• Document the unit's condition with dated move-in and move-out photos; this is your best evidence if there is a dispute.

What can and cannot be deducted

A landlord may deduct for unpaid rent and for damage beyond ordinary use, but normal wear and tear is never deductible. The difference matters:

• Allowed: unpaid rent, the cost to repair holes, broken fixtures, pet damage, heavy staining, or cleaning to return the unit to its move-in condition.
• Not allowed: faded paint, minor carpet wear from walking, small nail holes from hanging pictures, and general aging that comes from living in the place normally.

If you think a charge is really for wear and tear dressed up as "damage," say so in writing and ask for receipts or invoices supporting the amount.

Penalties for wrongful withholding

New Mexico's statute has real teeth. If a landlord fails to provide the required itemized accounting within 30 days, the landlord generally forfeits the right to keep any part of the deposit and can be ordered to return it. A tenant who has to sue may also recover reasonable attorney's fees and court costs, which is a strong incentive for landlords to follow the rules and for tenants to push back when they don't.

How to sue in small claims in New Mexico

New Mexico does not have a separate "small claims court." Smaller money disputes are filed in Magistrate Court across most of the state, or in the Bernalillo County Metropolitan Court if you are in the Albuquerque area. These courts handle civil claims up to $10,000, which covers nearly every deposit dispute.

• First, send a clear written demand letter listing the deposit amount, the missed 30-day deadline, and a deadline to pay.
• If that fails, file a civil complaint in the magistrate or metro court for the area where the property sits, and bring your lease, photos, the itemized statement (or proof none arrived), and your demand letter.
• You usually do not need a lawyer for these courts, but if the amount is large, the facts are messy, or the landlord has counsel, a New Mexico tenant attorney or a local legal aid program is worth a call.

This is general legal information, not legal advice. Landlord-tenant law changes, and individual cities or counties can add their own requirements, so confirm the current New Mexico rules or talk to a New Mexico attorney or legal aid office before you act.
