Massachusetts Late Rent Fee Laws: Limits, Grace Periods, and Penalties
What Massachusetts landlords can charge when rent is late, how long they must wait, and what an illegal fee costs. Last reviewed 2026-08-16.
How much can a landlord charge in Massachusetts?
Mass. Gen. Laws ch. 186 § 15B(1)(c) provides that no lease or other rental agreement shall impose any interest or penalty for failure to pay rent until 30 days after such rent shall have been due. Massachusetts sets no dollar or percentage ceiling once the 30 days have run, but the Attorney General's regulations and Chapter 93A treat a grossly excessive fee as an unfair and deceptive practice, and judges routinely refuse to enforce charges that look punitive. Fees in the four to five percent range with a stated maximum are the practical safe zone.
How late does rent have to be?
The statutory window is 30 calendar days from the rent due date, and it cannot be shortened by the lease. A clause saying a late fee applies after the fifth or the tenth is void as to that charge, even if the tenant signed it.
Does the fee have to be in the lease?
The late fee must be written into the lease or rental agreement to be collectible; an unwritten fee cannot be charged. Even a properly written clause is unenforceable to the extent it tries to bite before the thirty-first day.
What happens if you charge too much?
A late fee imposed inside the 30 day window is void and uncollectible, and 940 CMR 3.17 makes charging it an unfair and deceptive act. That triggers Mass. Gen. Laws ch. 93A, under which a tenant can recover double or treble actual damages plus attorney's fees and costs, and the claim is commonly raised as a counterclaim in an eviction.
Returned payment fees
No Massachusetts statute caps a landlord's returned payment fee. Many landlord sites cite Mass. Gen. Laws ch. 60 § 57A for a $25 limit, but that statute applies only to checks tendered to a city or town tax collector, not to private landlords. Charge no more than your actual bank fee, put it in the lease, and do not assess it inside the 30 day window, because it functions as a penalty for failure to pay rent.
Recent changes to the law
Massachusetts amended ch. 186 § 15B effective August 1, 2025 so that a residential rental broker's fee must be paid by whoever hired the broker, ending the practice of charging tenants for the landlord's broker. The 30 day late fee rule in § 15B(1)(c) was not changed.
What Massachusetts landlords get wrong
Massachusetts is the strictest state in this group and the mistake small landlords make is copying an out-of-state lease with a five day late fee clause. That clause is void and charging under it is a 93A violation that a tenant can turn into a counterclaim worth multiple damages and attorney's fees during your own eviction case. The 30 day rule does not slow down eviction: you can serve a 14 day notice to quit for nonpayment as soon as rent is late. Also note late fees are not rent, so they do not count toward what a tenant must tender to cure a nonpayment eviction.

Frequently asked questions
When can a Massachusetts landlord charge a late fee?
Not until rent is 30 days overdue. Mass. Gen. Laws ch. 186 § 15B(1)(c) bars any interest or penalty for failure to pay rent until 30 days after it was due, so a fee assessed on day five, ten, or fifteen is illegal. The 30 day window is set by statute and a lease cannot shorten it, even with the tenant's signature.
Is there a maximum late fee in Massachusetts?
No fixed cap once the 30 days have passed, but there is a practical limit. Courts will not enforce a fee that operates as a punishment rather than a reasonable charge, and the Attorney General's regulations make a grossly excessive fee an unfair and deceptive practice under Chapter 93A. Most Massachusetts landlords stay at four to five percent of monthly rent with a stated dollar maximum.
My Massachusetts lease says a late fee after 5 days. Is that legal?
No, that clause is void. Section 15B(1)(c) overrides it, so no penalty can be imposed until day 31 regardless of what you signed. If the landlord actually charged you under that clause, it is an unfair and deceptive act under 940 CMR 3.17 and Chapter 93A, and you may be able to recover double or treble damages plus attorney's fees.
Can a Massachusetts landlord evict me over late fees?
Not for the fees themselves. Nonpayment eviction is based on unpaid rent, and late fees are a separate charge that do not count as rent. That also means late fees are not part of what you must tender to cure a nonpayment case. A landlord who inflates the rent owed by adding fees risks a defective notice and a Chapter 93A counterclaim.
