The grace period in Massachusetts
Massachusetts requires a grace period of 30 days. A late fee charged before that is not enforceable, however the lease is worded. Day one of the grace period is the due date itself, so rent due on the 1st can first carry a fee on the 31st.
Does the fee have to be in the lease?
Yes. Massachusetts requires the late fee to be stated in the written rental agreement. A fee that is not in the lease is not collectable, no matter how reasonable the amount.
Charging it without getting it wrong
Most late-fee disputes are not about the amount. They are about the date the clock started, whether the fee was in the lease, and whether each payment was recorded against the right charge. Those are bookkeeping problems, and they are the ones that lose in court.
LandlordPro applies the grace period you set, charges the fee once, and records each payment against the oldest unpaid month first (that month's late fee when the payment covers it, then its rent), so the ledger shows where every dollar went. The rent roll shows exactly which day a charge landed and why, and the tenant sees the same breakdown in their portal.

Frequently asked questions
What is the maximum late fee a landlord can charge in Massachusetts?
Massachusetts does not set one by statute. Massachusetts sets no ceiling on the amount, but no interest or penalty for late rent may be imposed until thirty days after the rent was due — the longest statutory grace period in the country.
How many days late before a landlord can charge a fee in Massachusetts?
30 days. A fee charged before the grace period runs out is not enforceable.
Does a Massachusetts late fee have to be in the lease?
Yes. The statute requires the fee to be set out in the written rental agreement, so a fee charged without one is not enforceable.
Can a landlord charge a late fee every month the rent stays unpaid in Massachusetts?
Massachusetts does not address repeat fees by statute. Compounding a fee month after month on the same unpaid rent is the kind of charge courts treat as a penalty, so it is a risk worth avoiding.
Is a late fee the same as interest in Massachusetts?
No. A late fee is a one-off charge for the administrative cost of a late payment. Interest accrues over time and is regulated separately. Charging both on the same rent invites a challenge.
