New Mexico rent late fee law
What your landlord is allowed to charge when rent is late, how soon they can charge it, and what to do about a fee the law doesn't allow.

The cap
Under NMSA 1978 § 47-8-15(D) (as amended 2025), As of June 2025, New Mexico caps late fees at 5% of the rent for each rental period in default — down from the old 10% many sites still quote — and the fee may be calculated only on rent, never on deposits, other fees, or utilities.
When the fee can start
Rather than a grace period, New Mexico imposes a hard notice deadline: the landlord must give notice of the late fee no later than the last day of the next rental period after the missed payment — miss that window and the fee cannot be assessed at all. A late fee is allowed only if the rental agreement provides for it.
If you've been charged an illegal fee
The prevailing party in a suit under the Owner-Resident Relations Act is entitled to attorney's fees and costs, and charging fees not included in the rental agreement is now an unfair trade practice under New Mexico's Unfair Practices Act, with its own remedies.
Recent changes
Senate Bill 267 (effective June 20, 2025) cut the cap from 10% to 5%, restricted the fee base to rent only, and added Unfair Practices Act liability for undisclosed fees.
