Massachusetts Lease Amendment

Change rent, term, or occupants without rewriting the Massachusetts lease. Unchanged deposit-return and habitability duties stay in force.

All parties on the original lease should sign.
A month-to-month change still needs proper notice.
Do not use an amendment to skip Mass. Gen. Laws ch. 186, § 15B.

Deposit rule of thumb

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.

Mass. Gen. Laws ch. 186, § 15B

Massachusetts does not prescribe a statewide 24-hour entry statute. Put a reasonable-notice entry clause in the lease. Emergency entry is customary.

A tenancy at will generally takes notice equal to the rental interval, often 30 days (Mass. Gen. Laws ch. 186, § 12).
