A late fee is only collectible if your lease authorizes it. General information, not legal advice.

What N.M. Stat. §47-8-15(D) requires

  • Maximum fee: 5% of the rent for the period (lowered from 10% in 2025)
  • Grace period: None — the lease sets it
  • Lease requirement: the fee must be authorized in the written rental agreement — an unauthorized fee is uncollectible.
  • The cap dropped from 10% to 5% effective June 20, 2025 — leases written under the old ceiling need updating
  • To collect, the landlord must give written notice of the fee no later than the end of the next rental period after the default

Rules as of August 2026. Statutes change — verify with the current text of N.M. Stat. §47-8-15(D) before relying on a number, and check city and county ordinances, which can be stricter. This is general information, not legal advice; consult a New Mexico attorney for your situation.

Frequently asked questions

Did New Mexico's late fee limit change?

Yes. A 2025 amendment to §47-8-15(D) cut the maximum from 10% to 5% of the rent for the period, effective June 20, 2025. A lease clause written at 10% is now enforceable only to 5% — and the landlord still has to notice the fee by the end of the following rental period to collect it.
