Massachusetts Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights
Massachusetts Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights
Massachusetts landlords may collect a security deposit of no more than 1 month's rent (plus a separate last month's rent payment), must return it within 30 days of move-out, and must hold it in an interest-bearing account. Landlords must arrange entry in advance; there is no fixed statutory notice period, but emergency entry is allowed.
Security deposits in Massachusetts
Massachusetts law (M.G.L. c. 186, Section 15B) caps the security deposit at one month's rent. A landlord may separately collect the last month's rent up front, a first month's rent payment, and a lock-change fee, but cannot combine these into a supersized security deposit. The deposit must be deposited in a separate, interest-bearing bank account in Massachusetts within 30 days of receipt. The landlord must give the tenant a written receipt and the name and address of the bank. Interest accrues at the bank's passbook savings rate or 5 percent per year, whichever is higher, and is owed to the tenant annually or at move-out.
| Rule | Detail |
|---|---|
| Cap | 1 month's rent (plus last month separately) |
| Return deadline | 30 days after tenancy ends |
| Interest | Required; payable annually and at move-out |
Allowed deductions from the deposit include unpaid rent and documented damage beyond normal wear and tear. The landlord must provide an itemized list of deductions and receipts or repair estimates within the 30-day window. Failure to comply with these requirements can expose the landlord to liability for triple the deposit amount plus attorney's fees, a powerful tenant-protection mechanism unique to Massachusetts.
When can a landlord enter? Notice rules
Massachusetts does not set a fixed minimum notice period for landlord entry the way California (24 hours) or Arizona (48 hours) do. Instead, the law requires that entry be arranged in advance at a reasonable time. In practice, courts and the attorney general's office treat 24 hours as a safe benchmark, and leases often specify a notice period. A landlord who enters without advance arrangement or consent may face a claim of harassment or breach of the covenant of quiet enjoyment.
Emergency entry, such as a burst pipe or fire risk, is allowed without prior notice. Outside of emergencies, entry must occur at a reasonable hour. Tenants who believe a landlord is entering repeatedly without notice can contact the Massachusetts Attorney General's Consumer Protection Division or seek a court order.
Ending a lease: notice to vacate
To end a month-to-month tenancy in Massachusetts, either the landlord or the tenant must give at least 30 days' written notice, timed so that it expires at the end of a rental period. If the rental period is longer than 30 days, the notice must cover that full period. For example, if rent is due on the first and a tenant wants to vacate on April 30, notice should be delivered no later than April 1.
For fixed-term leases, no termination notice is needed since the lease ends on the agreed date, though many landlords send a reminder. For nonpayment of rent or lease violations, Massachusetts uses a specific notice process before eviction. See the Massachusetts eviction notice page for the required 14-day notice to quit and the summary process procedure, or visit the eviction notice hub for an overview.
Repairs and the warranty of habitability
Every residential rental in Massachusetts carries an implied warranty of habitability rooted in the State Sanitary Code (105 C.M.R. 410). The code sets minimum standards for heat (at least 68 degrees Fahrenheit from September 16 to June 14), hot water, structural safety, working plumbing, and pest control. A landlord who fails to maintain code-compliant conditions is in breach of the warranty.
Massachusetts does not provide a statutory repair-and-deduct remedy, meaning tenants generally cannot pay for repairs themselves and subtract the cost from rent. Instead, the primary remedy is rent withholding: a tenant may withhold rent by paying into court escrow after giving the landlord written notice and a reasonable time to repair. A court then decides what portion of the rent, if any, is owed. Tenants may also contact the local board of health to request an inspection, which can result in a formal violation notice requiring the landlord to repair within a set deadline.
Rent, late fees, and rent control
Massachusetts does not cap the late fee amount, but landlords may not impose any late fee until rent is at least 30 days overdue. A fee charged on day 5 or day 10, for example, is not authorized by Massachusetts law. Landlords must give tenants written notice of a rent increase for month-to-month tenancies at least 30 days before the new amount takes effect.
Rent control is permanently banned statewide under M.G.L. c. 40P, passed by voter referendum in 1994. No city or town in Massachusetts, including Boston or Cambridge (which had rent control before 1994), may enact or enforce any form of rent stabilization, rent control, or rent regulation. This prohibition is absolute and has been upheld repeatedly. Tenants seeking relief from high rents must rely on the market, income-based programs, or subsidized housing rather than local ordinances.
If you have a landlord-tenant dispute in Massachusetts
Document every interaction in writing. Send repair requests by email or certified mail and keep copies. If your landlord fails to return your deposit on time or provides no itemized statement, you may be entitled to triple damages plus attorney's fees under M.G.L. c. 186, Section 15B. Small claims court (limit $7,000) handles most deposit disputes without a lawyer.
For habitability problems, contact your local board of health first. The AG's Consumer Protection Division handles systemic landlord violations, and Massachusetts Legal Aid (masslegalhelp.org) provides free help for qualifying tenants. The Massachusetts Commission Against Discrimination handles housing discrimination claims. If you face eviction, contact Greater Boston Legal Services or another regional legal aid office as quickly as possible, since the timeline in summary process is short.
