Late rent fees in Massachusetts
There is no statutory cap. No fee may be charged until rent is 30 days late.
Maximum fee
No statutory cap
The longest grace period in the country at 30 days, and no statutory cap on the amount. A 5% cap is widely repeated online but is a proposed amendment - do not state it as law.
“No lease or other rental agreement shall impose any interest or penalty for failure to pay rent until thirty days after such rent shall have been due”
Mandatory grace period
30 days
“No lease or other rental agreement shall impose any interest or penalty for failure to pay rent until thirty days after such rent shall have been due”
The grace period is not a new due date
This is the detail landlords most often get wrong. A 30-day grace period in Massachusetts controls when the feeapplies — it does not move the day rent is due. Rent due on the 1st is still late on the 2nd, and in most states a pay-or-quit notice can be served then. Only the fee waits.
Your lease can be more generous than the statute, never less. A longer contractual grace period is fine; a shorter one is void.
A fee above the cap is void, not reduced
Statutory caps are mandatory, and a tenant’s signature does not cure an unlawful clause. Several states go further and attach a penalty to charging one: Colorado imposes $50 per violation, and Maryland makes the clause unenforceable and exposes the landlord to the tenant’s actual damages and legal fees. This is not a “worst case, they just don’t pay it” situation.
Watch out for the wrong statute
If you search for your state’s late fee limit you will very likely be told it is “$20 or 20% of monthly rent, whichever is greater”. In nine states that rule is real, but it sits in the self-service storagestatute, not residential landlord–tenant law. It does not govern a house or an apartment. Two other widely-quoted figures — Arizona’s “$50 or 5%” and North Dakota’s 8% — come from bills that never passed. The comparison page explains which is which.
Common questions
- How much can a landlord charge for a late fee in Massachusetts?
- Massachusetts sets no statutory cap. That does not mean any amount is lawful — The longest grace period in the country at 30 days, and no statutory cap on the amount. A 5% cap is widely repeated online but is a proposed amendment - do not state it as law.
- Does Massachusetts require a grace period before charging a late fee?
- Yes — 30 days under M.G.L. c.186 s.15B(1)(c). Charging inside that window is unlawful regardless of what the lease says.
- Can I charge a late fee if it is not in the Massachusetts lease?
- No. In virtually every state a late fee is only enforceable if the signed lease states it — the amount, when it applies, and any grace period. If the lease is silent you cannot impose one mid-tenancy without an amendment both parties agree to.
