Most common red flags in Massachusetts leases

Massachusetts renter laws worth knowing

Strict limits on move-in costs

At the start of a tenancy, a Massachusetts landlord may only collect four things: first month's rent, last month's rent, a security deposit of no more than one month's rent, and the actual cost of a new lock and key. Anything else, such as a pet fee or an amenity fee, is unlawful.

Deposits must be in a separate account with interest

The deposit must be held in a separate Massachusetts bank account, and you must receive a receipt naming the bank and account number within 30 days. You are entitled to 5% interest or the actual interest earned, paid annually.

Statement of condition

Within 10 days of move-in, the landlord must give you a signed statement of the unit's condition. This is your protection against later damage claims.

Late fees only after 30 days

Massachusetts prohibits charging a late fee until rent is at least 30 days overdue. Leases commonly violate this with a fee after five days.

The bottom line

Massachusetts has the strictest move-in cost and deposit rules in the US. If your landlord asked for a pet fee or an application fee on top of the deposit, that is likely unlawful.

Renting in a Massachusetts city?

Local ordinances can add protections on top of state law. Renters in Boston, Worcester, Springfield, Cambridge, Somerville and Lowell should check city rules too — especially around rent increases, deposits, and eviction notice periods.
