Pests, mold, and unsafe conditions in New Brunswick
Keeping the place free of pests like bed bugs, mice, and cockroaches, and dealing with mold, is the landlord's responsibility. Report it in writing right away.
What can I do about pests, mold, or unsafe conditions in New Brunswick?
For tenants
Your landlord has to keep the unit fit to live in, and that covers pests like bed bugs, mice, and cockroaches, plus mold. Report it in writing as soon as you notice it, and keep your own space reasonably clean. If the landlord does nothing, use the complaint process with the Office. For a serious health or safety hazard you can also call your municipality's property-standards or by-law office and your regional Public Health office. A landlord can only try to charge you for pest control if they can prove you brought the problem in, which is decided case by case.
For landlords
Pest control and mold are part of keeping the unit fit to live in, and the municipal maintenance code requires units to be kept free of rodents and insects. Act quickly when a tenant reports it. You can only pass costs to a tenant if you can prove they caused the infestation through negligence, and the burden is on you.

Common questions
We have mice or bed bugs and my landlord has not done anything. What can I do?
Pest control is your landlord's responsibility. Report it in writing, and if they do nothing, serve a Notice of Complaint and file an Application for Assistance with the Office. For a real health hazard you can also call your municipality's property-standards office and your regional Public Health office.
There is mold in my apartment. Whose problem is it?
Mold is the landlord's responsibility as part of keeping the place fit to live in. Report it in writing with photos, keep the unit ventilated on your side, and if it is not fixed, take it to the Office. For a health risk, your municipal standards office or Public Health can also inspect.
