Bed bug liability in rental housing
Bed bug laws in Massachusetts
Who pays for treatment?
Habitability law only
No bed bug statute, but one of the strongest general pest regimes in the country — and everything turns on one question: how many units are in your building. Two or more, and the owner must keep the place free from infestation and is responsible for elimination, full stop. A single-unit residence flips it: the occupant is responsible, unless the owner failed to maintain the structural elements that let pests in. Massachusetts also has the fastest inspection clock anywhere — the board of health must inspect within 24 hours of an insect complaint.

What the law actually says
105 CMR 410.550 (extermination of insects, rodents and skunks), State Sanitary Code ch. II, as amended by Mass. Register issues 1495 and 1497. (A) Residences containing one dwelling unit — the occupant shall maintain the unit free from all pest infestation and is responsible for pest elimination; the owner is responsible if they have not maintained structural or other building elements necessary to keep pests from entering. (B) The owner of a residence containing two or more dwelling units, including a homeless shelter or rooming house, shall maintain it and its premises free from infestation and shall be responsible for pest elimination. (D)(1) Pesticide applicators or their employers must give at least 48 hours pre-notification to occupants of ALL residential units before any commercial application for indoor household or structural pests; (D)(2) that notice must be in writing and state the company name and phone number, the proposed date, the locations to be treated, and the names, EPA registration numbers and active ingredients of the products that may be used. (D)(3) owners and occupants must provide access on that notice and follow the applicator's preparation instructions. (E) occupants must keep the unit sanitary so as not to attract pests. (F) the owner must inspect each unit before a new occupancy to identify pests. (G) documented inspection results and actions taken must be available to the board of health on request. 105 CMR 410.750(A)(5) — failure to eliminate insect infestations is a condition that may endanger or materially impair health or safety. 105 CMR 410.820(A)(k) — the board of health or inspectional services must inspect within 24 hours of receiving an insect infestation complaint. Pesticide rules cross-refer to 333 CMR 13.00. FLAG: S.1062 would have created a bed-bug-specific act using an actual-or-constructive-knowledge standard; that is bill text, not law — confirm before citing.

What to do, in order
Photograph everything before you touch it
Live insects, shed skins, dark staining along the mattress seam. Timestamps are the evidence.
Notify the landlord in writing
Email or certified letter, never a phone call alone. Written notice generally creates the clearest evidence that the landlord’s response period has begun.
Do not throw out furniture yet
Discarded items can't be inspected, and moving them spreads the infestation down the hallway.
Let the deadline above run
Using remedies before you complete the required notice and waiting periods can weaken or eliminate them.
Escalate to the housing agency, then to court
An independent inspection report is worth more than your own photographs. Rent withholding rules vary sharply — check the section above before you try it.
Read it yourself
