Can You Legally Break a Lease Early in Cambridge, MA?
Yes, under certain conditions, tenants in Cambridge can legally break a lease early without penalty.

You must either have a legal justification or rely on the lease termination clause in your rental agreement to avoid financial consequences.
What is "Early Lease Termination"?

Valid Legal Reasons to Break a Lease Without Penalty

Under Massachusetts law, tenants can break a lease without penalty for the following reasons:
1. Domestic Violence or Stalking
If you are a victim of domestic violence, sexual assault, or stalking, Massachusetts provides protections that allow you to terminate your lease early.

2. Active Military Duty
Under the Servicemembers Civil Relief Act (SCRA), tenants called to active duty can break a lease without penalty.
Written notice and a copy of military orders are required.
3. Uninhabitable or Unsafe Living Conditions

The landlord must have failed to fix these issues after being notified in writing.
4. Landlord Harassment or Retaliation
Harassment, illegal entry, or retaliation for asserting your tenant rights can justify breaking a lease.
Massachusetts landlord retaliation laws protect you from unfair treatment.
5. Landlord Violates the Lease

How Much Notice Must You Give to Vacate?

- Fixed-Term Lease: Typically requires 30 days’ written notice.
