New Mexico Late Rent Fees: Legal Limits for Landlords

If you’re a New Mexico renter facing a late rent charge, it’s important to know the legal limits on what landlords can require. Understanding New Mexico’s specific rules about late rent fees can help you avoid unfair charges and know your options for addressing disputes.

How Much Can Landlords Charge in Late Rent Fees in New Mexico?

New Mexico law specifically regulates late fees for residential tenants. According to state statute, a landlord may charge a late fee, but it must be reasonable and in line with the law.

  • Maximum late fee: Landlords can charge up to 10% of the rent payment that is past due.[1]
  • Late fees must be specified in your written rental agreement.
  • Late fees must not be "disguised" as other charges unrelated to a late payment.

For example, if your monthly rent is $900, the most your landlord can charge as a late fee is $90 per month for any missed or late rent payment, provided this is clearly stated in your lease agreement.

When Can a Landlord Charge a Late Rent Fee?

Late fees can only be imposed if:

  • The written rental agreement explicitly allows for late fees.
  • The rent remains unpaid after the date specified in your lease.

If the lease says rent is due on the 1st and there's a "grace period" of 3 days, you won't be charged a late fee unless payment is made after the grace period ends.

What If a Landlord Charges Too Much?

If your landlord demands a late fee above 10% of your overdue rent, or tries to charge penalties not listed in your lease, this violates New Mexico's Uniform Owner-Resident Relations Act.[1] In this case:

  • Let your landlord know about the legal limit and refer them to the relevant state law.
  • Document all communications and charges.
  • If the landlord refuses to adjust the fee, you can file a complaint or seek assistance. See the Resources section below for where to turn.
If you believe you are being charged an illegal late fee, keep written records and reach out to the official local housing authority or tribunal for help.

Relevant Forms for New Mexico Renters

  • Notice of Dispute/Complaint Form: New Mexico does not have a standardized statewide complaint form, but you may use a written statement or ask your local Attorney General's Consumer Complaint process.
    • Use this if you want to officially dispute a late fee or other landlord charge.
    • Example: If your landlord charges a $150 late fee on $800 rent, you could file a complaint through the Attorney General’s site to seek redress.
  • Rental Agreement: Not a government form, but your lease is the controlling contract for rent and late fee terms in New Mexico. Always request a copy if you need one for dispute purposes.
