A security deposit generally may not exceed one month’s rent (Mass. Gen. Laws ch. 186, § 15B). First month’s rent, last month’s rent, and a reasonable lock/key fee may also be collected. Hold the deposit in a separate Massachusetts account, give the statutory receipts, and pay interest. Unused deposit plus an itemized list is generally due within 30 days. Noncompliance can cost triple damages.
A tenancy at will generally takes notice equal to the rental interval, often 30 days (Mass. Gen. Laws ch. 186, § 12).
Massachusetts does not prescribe a statewide 24-hour entry statute. Put a reasonable-notice entry clause in the lease. Emergency entry is customary.
A Massachusetts rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A tenancy at will generally takes notice equal to the rental interval, often 30 days (Mass. Gen. Laws ch. 186, § 12). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
Massachusetts nonpayment usually starts with a 14-day notice to quit. The tenant may be able to cure by paying before the summary-process hearing. This is not a summary-process summons.
A 14-day notice to quit is the usual nonpayment notice (Mass. Gen. Laws ch. 186, § 11 or § 12).
Pay-or-quit deadline: 14 days
A notice to quit should be served carefully, often by constable. The later summons is a separate paper.
Massachusetts residential leases commonly need these statewide disclosures. The lease generator adds them when your answers trigger them.
Section 15B receipts and account
Give the statutory deposit receipt, hold the money in a separate interest-bearing Massachusetts account, and notify the tenant of the bank. Missing these steps can forfeit the deposit and trigger triple damages.
These Massachusetts cities often have rent-control, just-cause, or relocation rules on top of state law. Confirm the ordinance before you raise rent or decline to renew.
