Massachusetts renters insurance and security deposit guide

By Alishahi Insurance, independent broker · CA License #4348151 · Updated October 2026

Short answer: In Massachusetts, your landlord's policy doesn't cover your belongings or liability. Under M.G.L. c. 186 §15B, a security deposit can't exceed the first month's rent. A landlord who takes one must give you a written statement of the unit's condition within 10 days. The landlord must return the deposit, or any balance after lawful deductions, within 30 days after your tenancy ends. Reasonable wear and tear is excluded. Some violations can mean three times the deposit plus interest, costs and attorney's fees.

This guide is general information for Massachusetts renters. It isn't legal advice, and local ordinances can add rules. Your lease and policy wording control.

Your landlord's policy covers the building, not your belongings or liability. A renters policy (HO-4) covers personal property, personal liability and loss of use; flood is generally excluded (see FloodSmart). Coverage basics: renters insurance. Roommates: whether renters insurance covers roommates. Liability: how much renters liability coverage you need.

Step 1: Move-in rules

Under M.G.L. c. 186 §15B:

  • A landlord may collect first month's rent, last month's rent, a lock-change fee and a security deposit no greater than the first month's rent.
  • If the landlord takes a deposit, they must give you a separate written statement of the present condition of the unit, including a comprehensive listing of existing damage, at the start of the tenancy or within 10 days after it begins, whichever is later. Review it and note anything missing.
  • Deposits must be held in a separate, interest-bearing account in a Massachusetts bank, and you're entitled to interest.

Step 2: The 30-day return

  • Within 30 days after the tenancy ends, the landlord must return the deposit or any balance.
  • Deductions are limited to unpaid rent or water charges, certain tax escalation amounts, and a reasonable amount to repair damage you caused, reasonable wear and tear excluded. For damage, the landlord must provide an itemized list under oath with written evidence of cost.

Step 3: Treble damages

Under §15B(7), if the landlord fails to comply with certain return requirements, you're awarded three times the deposit or balance due, plus 5% interest, court costs and reasonable attorney's fees.

Step 4: Winter storms and water

Nor'easters, ice dams and frozen pipes are common Massachusetts claims. Renters insurance typically covers your belongings for sudden water and wind damage. Flood is generally excluded; see FloodSmart.
