New Mexico's Uniform Owner-Resident Relations Act (UORRA) 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 a firm cap on the amount landlords can demand.
Maximum Security Deposit Limits
Under NMSA § 47-8-18, New Mexico imposes a strict cap on the amount of security deposit an owner may demand:
- Universal One-Month Cap: For the vast majority of residential tenancies, the security deposit cannot exceed one month's rent. This limit applies to both short-term and long-term leases.
- Exception for Rent Paid in Advance: The only statutory exception allowing a deposit in excess of one month's rent is for a lease with a term of one year or more where the rent is paid in advance.
- Interest Requirement: If a landlord requires a deposit of exactly one month's rent for a lease of one year or more, they must pay interest to the resident annually at the passbook interest rate (NMSA § 47-8-18). Ownership of the interest belongs to the resident.
Return of the Security Deposit
Landlords must adhere to a strict timeframe when returning a security deposit:
- Deadline: Within 30 days after the termination of the rental agreement or the tenant's departure, whichever is later.
- Forwarding Address: The landlord's obligation to return the deposit within 30 days only applies if the tenant provides a forwarding address.
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:
- Forfeiture: The landlord forfeits the right to keep any portion of the deposit, regardless of the damage to the unit.
- Damages: The landlord forfeits the right to sue the tenant independently for damages to the premises.
- Financial Penalty: The tenant can sue the landlord in court. If the landlord acted in "bad faith," they may be liable for a civil penalty of $250, plus the full deposit amount, plus reasonable attorney's fees and court costs.
