As a tenant in New Brunswick, dealing with mold or infestations can be stressful. Understanding your rights and responsibilities in these situations is crucial. This guide will help you navigate your options while ensuring your living environment remains safe and healthy.

Mold and Infestations: Tenant Rights and Landlord Responsibilities

In New Brunswick, both tenants and landlords have specific obligations concerning maintenance and repairs. When it comes to mold and infestations, your landlord is typically responsible for ensuring your rental unit is habitable and safe for living. This includes taking care of mold remediation and pest control, provided you haven’t caused these issues through neglect or misuse.

Landlords must keep the unit habitable and address mold remediation and pest control. Keep dated photos and written notices, and be prepared to seek help from the Residential Tenancies Tribunal if problems persist.

Recognizing and Reporting Mold Issues

Mold can often be spotted as black, green, or white spots on damp surfaces. It's vital to report any signs of mold to your landlord immediately. Failing to do so may exacerbate the issue and complicate the resolution process. Provide your landlord with written documentation, perhaps an email or letter, detailing the mold problem and requesting timely remediation.

Tip: Document mold signs with dated photos and send a brief written report requesting a remediation timeline; keep a copy of your message and any landlord responses.

Addressing Infestations in Your Rental Unit

Pest infestations, such as rodents or insects, should be reported to your landlord promptly. Landlords are generally required to manage these issues unless the infestation is a result of tenant breach, such as leaving food out, poor cleanliness, or not taking reasonable pest control measures.

Caution: If the infestation continues despite reporting, document dates and any pest-control actions; a persistent problem may require formal steps with the tribunal or health authorities.
