Frequently asked questions
Why are Massachusetts security deposits so carefully regulated?
Massachusetts imposes detailed receipt, escrow, and statement requirements. Landlords who mishandle deposits can owe multiple damages, so renters should verify paperwork carefully.
Before you sign
Statutes set the floor — your lease can still include junk fees, auto-renewals, one-sided indemnification, or deposit language that conflicts with Massachusetts law. Comparing the document to M.G.L. c. 186 / c. 239; 105 CMR 410 is the fastest way to spot problems early.
