Massachusetts Landlord-Tenant Laws

Massachusetts limits security deposits to one month's rent and requires return within 30 days after the tenant moves out. There is no fixed statutory entry-notice period, and 30 days (or one full rental period) ends a month-to-month tenancy.

Informational summary, not legal advice. Landlord-tenant law changes and local ordinances may add requirements. Verify the current statute (M.G.L. ch. 186, 15B (deposits); ch. 186, 12 (termination)) or consult a licensed Massachusetts attorney before acting. All rentals must also comply with the federal Fair Housing Act — you may not select tenants or write listings based on a protected class.
