Can a landlord retaliate against a tenant for complaining in Massachusetts?

No. In Massachusetts, a landlord who retaliates against a tenant for reporting a code violation, complaining in writing to the landlord, pursuing a housing claim or joining a tenants’ union is liable for one to three months’ rent or actual damages, and a termination notice (other than for nonpayment), rent increase or other substantial change within six months after the tenant’s act is presumed to be a reprisal. The presumption can be rebutted only by clear and convincing evidence. Separately, the federal Fair Housing Act makes it unlawful to threaten or interfere with anyone for exercising fair housing rights. This is M.G.L. c. 186, § 18.

How Seayora uses this rule

When an owner prepares an eviction in Seayora, it lists any repair request opened on the unit in the last 180 days that is still open, not to stop the case but because the tenant will raise retaliation and the owner should have an answer. Every repair request keeps the date it was filed.
