New Mexico Security Deposit Laws: Strict Limits & Interest Rules

New Mexico's Uniform Owner-Resident Relations Act (UORRA), effective since 1978, dictates strict rules for the collection, handling, and return of residential security deposits. Unlike many jurisdictions that offer flexibility for longer lease terms, New Mexico maintains specific caps based on the duration of the rental agreement.

Maximum Security Deposit Limits

Under NMSA § 47-8-18, New Mexico imposes limits on the amount of security deposit an owner may demand based on the lease term:

• Leases Less Than One Year: For rental agreements with a term of less than one year, the security deposit cannot exceed one month's rent.
• Leases of One Year or More: For rental agreements of one year or more, there is no statutory maximum limit, but the deposit amount must be reasonable.
• Interest Requirement: If a landlord requires a deposit greater than one month's rent (which is permitted for leases of one year or more), they must pay the resident annual interest at the passbook interest rate permitted to savings and loan associations in New Mexico by the federal home loan bank board. If the deposit is less than or equal to one month's rent, the owner is not required to pay interest (NMSA § 47-8-18(A)(1)-(2)). Ownership of any required interest belongs to the resident.

Return of the Security Deposit

Landlords must adhere to a strict timeframe and procedure when returning a security deposit:

• Deadline: Within 30 days after the termination of the rental agreement or the resident's departure, whichever is later.
• Mailing Requirement: The owner complies with the return requirement by mailing the itemized statement and any remaining deposit to the resident's last known address. This 30-day obligation applies regardless of whether the resident provided a new forwarding address (NMSA § 47-8-18(D)).

Permissible Deductions

Landlords may deduct funds from the security deposit for:

• Unpaid rent.
• Unpaid utilities that were the tenant's responsibility.
• Actual damages to the unit caused by the tenant or their guests, excluding normal wear and tear.

If deductions are made, the landlord must provide an itemized written statement detailing the deductions alongside the remaining deposit balance within the 30-day window.

Penalties for Non-Compliance

If a landlord fails to provide the written itemized statement and the remaining deposit within 30 days (NMSA § 47-8-18(D)-(E)):

1. Forfeiture of Rights: The owner forfeits the right to withhold any portion of the deposit, the right to assert counterclaims for the deposit, and the right to sue the resident independently for damages to the premises.
2. Financial Penalty: An owner who in bad faith retains a deposit is liable for a civil penalty of $250, plus court costs and reasonable attorney's fees.
