New Mexico heavily regulates how and when a landlord can charge a late fee. Under the Uniform Owner-Resident Relations Act (UORRA), as amended effective June 20, 2025, there are strict calculation requirements for allowable late fees.
The 5% Late Fee Cap
Under NMSA § 47-8-15(D), the maximum late fee a New Mexico landlord can charge is 5% of the rent for each rental period that the resident is in default.
The Calculation Rule
Late fees must be calculated strictly on the rent amount. Rent calculations to determine late fees shall NOT include:
- Security deposits.
- Additional fees.
- Utilities.
- Previous unpaid late fees (compounding late fees are illegal).
Lease Requirements
For a late fee to be legally enforceable, it must meet two criteria:
- Specified in the Lease: The exact late fee amount or percentage (up to 5%) must be clearly stated in the written rental agreement. If the lease is silent on late fees, none can be charged.
- No Unfair Practices: Charging undisclosed or unauthorized late fees is classified as an unfair or deceptive trade practice in New Mexico.
Grace Periods
Unlike many other states, New Mexico law does not mandate a statutory grace period for late fees. Late fees may be assessed immediately after the rent due date, provided the specific fee and terms are clearly outlined in the written rental agreement.
Notice Requirements
To legally assess a late fee, the owner must provide the resident with written notice of the charge no later than the last day of the next rental period immediately following the period in which the default occurred. Failure to provide this timely written notice results in a waiver of the late fee for that period.
Interaction with Eviction
In New Mexico, a landlord can serve a 3-Day Notice to Pay or Quit the day after rent is due. The landlord does not have to wait to charge a late fee before beginning the eviction process in the appropriate Magistrate or Metropolitan Court.
