Massachusetts Late Fee Laws

Statute
Mass. Gen. Laws ch. 186, § 15B(1)(c)

Massachusetts sets no statutory dollar cap on residential late fees — Mass. Gen. Laws ch. 186, § 15B(1)(c) governs the landlord–tenant relationship, and courts still expect a late fee to be a reasonable estimate of actual damages rather than a penalty.

Timing matters as much as the amount: rent must be at least 30 days past due before a late fee can be assessed. A fee charged inside that window isn't collectible in Massachusetts, even when the lease provides for it.

Massachusetts caps nothing but imposes the longest mandatory grace period in the country: no late fee (or interest) may be assessed until rent is 30 days overdue. Any lease clause purporting to charge earlier is void.
