Quick Answer: Security deposits in New Mexico are capped at one month's rent when the lease runs less than a year. On an annual lease, a landlord can charge more if the amount is reasonable, but must pay you yearly interest on it. Landlords then have 30 days after move-out to return the balance with an itemized list of deductions.
Renters in Albuquerque, from Uptown to Nob Hill, follow the same rule as the rest of the state: security deposits in New Mexico are governed by Section 47-8-18 of the Uniform Owner-Resident Relations Act. It caps what a landlord can collect, bans deductions for normal wear and tear, and sets a 30-day refund deadline with real penalties. It pairs well with our explainer on what a lease renewal notice means for you.
What Are Security Deposits in New Mexico?
A security deposit is money a landlord holds to cover unpaid rent or damage a resident causes during the tenancy. New Mexico law calls the landlord the owner and the tenant the resident, and Section 47-8-18 says any deposit must be reasonable. How much counts as reasonable depends mostly on how long your lease runs.
Security Deposit Limit by Lease Length
On any rental agreement shorter than one year, including month-to-month, the owner can't demand or receive more than one month's rent. Paying $1,200 a month on a six-month lease? Your deposit tops out at $1,200.
Annual leases have no fixed ceiling, but the amount must still be reasonable, and anything above one month's rent triggers a yearly interest payment to you. Courts enforce that test. In Hedicke v. Gunville (2003), the Court of Appeals refused to treat a $50,000 payment as a deposit at all.
Here's how the security deposit laws apply to the situations renters ask about most:
| Situation | What the Landlord Can Do | NMSA 47-8-18 |
|---|---|---|
| Lease shorter than one year | Charge up to one month's rent | Subsection A(2) |
| Annual lease, deposit above one month's rent | Charge a reasonable amount and pay yearly interest | Subsection A(1) |
| Last month's prepaid rent | Collect it if the lease requires it; it is not the deposit | Subsection B |
| Normal wear and tear at move-out | Cannot deduct anything for it | Subsection C |
| Itemized list not sent within 30 days | Loses the right to keep any of it and owes court costs and attorney fees | Subsection D |
Rental Security Deposit Rules for Albuquerque Renters
Last month's prepaid rent isn't a security deposit, and a damage deposit can't be relabeled as prepaid rent either. The rules apply statewide, though the New Mexico Supreme Court Law Library's landlord-tenant resource guide notes local ordinances can add requirements. If a landlord also asks for a guarantor, our guide to when you need an apartment guarantor explains what that person signs up for.
What Can a Landlord Deduct From an Apartment Security Deposit?
At move-out, a landlord can apply the deposit to unpaid rent, unpaid utilities, repair work and other legitimate damages caused by the resident breaking the lease or the resident duties in Section 47-8-22. The one firm exclusion is normal wear and tear. No part of security deposits in New Mexico can be kept to cover it.
Where the Wear-and-Tear Line Falls
Section 47-8-18 bans wear-and-tear deductions without listing examples, so the line gets drawn case by case. That's why your move-in record matters. Date-stamped photos of every room give you something concrete to point to if a charge looks like routine upkeep.
One exception to security deposits in New Mexico catches renters off guard. In Bruce v. Attaway (1996), the New Mexico Supreme Court ruled that a landlord could apply the deposit to a rent shortfall without a written itemization. Damage deductions still need the list.
How Does Security Deposit Return Work in New Mexico?
Security deposit return runs on a 30-day clock. The landlord must send the remaining balance and an itemized written list of deductions within 30 days of the lease ending or the resident leaving, whichever comes later. Mailing both to your last known address counts as compliance, so give your landlord a forwarding address in writing.
Miss that window and the landlord forfeits the right to withhold any portion of the deposit, can't counterclaim in a suit to recover it, owes your court costs and reasonable attorney fees, and loses the right to sue separately for property damage. The state Supreme Court applied exactly that outcome in Garcia v. Thong (1995).
Bad faith costs more: a $250 civil penalty payable to the resident.
Timely landlords keep options, though. In Stodgell v. Weissman (2025), a landlord who itemized within 30 days could still pursue damages beyond the original list. And if you're staying past your end date, a lease extension moves your termination date, and with it the start of the clock.
What Tenant Rights New Mexico Law Gives You in a Deposit Dispute
Your strongest tool is the statute itself, which spells out penalties a landlord can't negotiate away. Most disputes over security deposits in New Mexico start with a written request citing Section 47-8-18 and the 30-day deadline. If that fails, residents can file a complaint for return of deposit on a standard court form without hiring an attorney.
These rental security deposit laws sit inside the broader NM rental laws of the Uniform Owner-Resident Relations Act. Knowing the laws for security deposit refunds before you move out beats learning them mid-dispute.
Filing a Deposit Claim in Albuquerque
Albuquerque renters file with the Bernalillo County Metropolitan Court, which hears landlord-tenant cases up to $10,000. Its Metro Court Self-Help Center at 401 Lomas NW, Room 210, helps people represent themselves and stocks the Civil Complaint by Resident for Return of Deposit.
Elsewhere, magistrate courts hear the same claims, and the New Mexico Courts landlord-tenant forms library is the place to start. For free guidance first, call the New Mexico Landlord Tenant Hotline at (505) 930-5666.
Frequently Asked Questions
1. Is there a security deposit limit on a 12-month lease in New Mexico?
No fixed dollar cap applies to an annual lease in New Mexico. The deposit must be reasonable, and if it's greater than one month's rent, the landlord owes you interest every year. The hard one-month cap only covers rental agreements shorter than one year, including month-to-month tenancies.
2. How long does a landlord have to return a security deposit in New Mexico?
A landlord has 30 days from the end of the rental agreement or your move-out date, whichever is later. Within that window you should receive any remaining balance plus an itemized written list of deductions. A landlord who misses it loses the right to withhold any part of the deposit.
3. Does a New Mexico landlord have to pay interest on a security deposit?
Only on an annual lease where the deposit is greater than one month's rent. Section 47-8-18 ties the rate to the passbook interest permitted to savings and loan associations by the Federal Home Loan Bank Board. That board was abolished in 1989, so ask your landlord in writing how the rate is calculated.
4. What should I do if my landlord won't return my apartment deposit?
Work through these steps in order:
- Send a written demand citing NMSA 47-8-18 and the 30-day deadline
- Gather your lease, move-in photos, move-out photos and rent receipts
- Call the New Mexico Landlord Tenant Hotline at (505) 930-5666
- File a complaint for return of deposit in Metro Court or your county's magistrate court
5. Is last month's rent the same as a security deposit in New Mexico?
No. Section 47-8-18(B) keeps last month's prepaid rent separate from the security deposit, so a lease can require both. The statute also blocks the reverse, meaning a damage deposit can't be treated as prepaid rent. Check your lease to see which payment is which.
Conclusion
Security deposits in New Mexico come down to a few firm rules: one month's rent on short leases, reasonable amounts with interest on annual ones, no charges for wear and tear, and a 30-day itemized refund. Whether you rent in Uptown, the Northeast Heights or anywhere else in Albuquerque, a move-in photo set and a written forwarding address protect most of your money.
