Massachusetts late rent fee: the legal maximum
Massachusetts sets no statutory cap on late fees. The amount is whatever the lease says, subject to the general rule that it must not be an unconscionable penalty. Rent must be at least 30 days late before any fee may be charged.
Reference: 5% of rent at common rents
Massachusetts has no cap. Five percent of monthly rent is the most common lease figure and the statutory cap in several other states; it is shown for comparison only.
| Monthly rent | 5% reference |
|---|---|
| $1,000.00 | $50.00 |
| $1,500.00 | $75.00 |
| $2,000.00 | $100.00 |
| $3,000.00 | $150.00 |
What the statute says
No statutory cap on the amount, but no interest or penalty for late rent may be imposed until rent is 30 days overdue (M.G.L. c. 186 § 15B(1)(c)).
How this applies in practice
- A late fee must be written into the lease. The statute constrains what the lease may say; it does not create a fee on its own.
- Rent is not "late" for fee purposes until 30 days after the due date. A fee charged earlier is unenforceable.
- Courts treat a late fee as liquidated damages: it must approximate the landlord’s real cost of late payment. Fees far above 5% of rent, or that compound daily without limit, are the ones that get struck down.
- Late fees are separate from interest on unpaid rent and from eviction filing costs, which have their own rules.

Frequently asked questions
What is the maximum late fee for rent in Massachusetts?
There is no statutory maximum in Massachusetts. No statutory cap on the amount, but no interest or penalty for late rent may be imposed until rent is 30 days overdue (M.G.L. c. 186 § 15B(1)(c)). The most common lease figure nationally is 5% of monthly rent, and courts in no-cap states generally accept fees in that range while rejecting ones that look like penalties.
Is there a grace period for rent in Massachusetts?
Yes. State law requires rent to be 30 days late before a late fee can be charged, regardless of what the lease says.
Can a Massachusetts landlord charge a daily late fee?
Nothing in state law forbids it, but the total must remain reasonable. A daily fee that quickly exceeds a few percent of rent risks being struck down as a penalty.
Can a landlord charge a late fee that is not in the lease in Massachusetts?
No. A late fee is a contract term. If the lease does not provide for one, the landlord cannot impose it, and in Massachusetts the statutory reasonableness standard applies on top of whatever the lease says.
