Massachusetts is famous for having the longest mandatory late fee grace period in the United States: 30 full days. This means a landlord cannot charge a late fee until the rent is a full month overdue-a rule that surprises many landlords unfamiliar with the law.
Official Law Citation: Massachusetts General Laws Chapter 186, Section 15B(1)(c).
The 30-Day Grace Period
Under MGL Chapter 186, Section 15B, a late charge or late fee can only be imposed on a tenant after the rent has been due and unpaid for 30 full days.
Example: If rent is due on the 1st of the month, the landlord cannot charge any late fee until the 1st of the following month.
This means the popular practice of charging a late fee on, say, the 5th of the month with a "5-day grace period" is illegal in Massachusetts.
Lease Requirements for Late Fees
Even after the 30-day grace period expires, a late fee is only enforceable if:
- It is specified in the lease: The lease must clearly state the exact amount of the late fee.
- It is reasonable: Massachusetts courts will strike down late fees that are deemed excessive or punitive. While there is no specific statutory cap, the fee should generally reflect the landlord's actual administrative costs incurred by the late payment. A reasonable late fee is typically considered to be around $50 or a small percentage of one month's rent.
Compounding Late Fees
Charging compounding or stacking late fees (e.g., $50 for the first day late, then $10 for every additional day) faces extreme scrutiny. Because of the 30-day grace period, landlords cannot build up a series of daily charges; they can only apply a single fee once the 30-day threshold is crossed.
Late Fees and the Security Deposit
A critical rule: Late fees cannot be deducted from the security deposit. Under §15B, the security deposit can only be used for:
- Unpaid rent.
- Damage beyond normal wear and tear.
- Certain unpaid real estate tax escalations.
A late charge is a separate, distinct fee and must be collected separately.
Late Fees vs. the Eviction Process
The 30-day grace period for late fees is separate from the eviction timeline. A landlord can begin the eviction process (14-day Notice to Quit for non-payment) as soon as rent is late-they do not have to wait 30 days to start the eviction. The 30-day rule only applies to charging a fee.
