Mold and infestations in rental properties can pose significant health risks and discomfort for tenants. In New Brunswick, tenant rights regarding maintenance and repairs are governed by the Residential Tenancies Act[1]. This guide covers your rights and steps to address mold and infestation issues effectively.

Under the Residential Tenancies Act, landlords must maintain the unit in habitable condition and promptly address mold and infestations. Always report in writing and keep copies of notices, responses, and photos as part of your file.

Understanding the Problem: Mold and Infestations

Mold growth often results from excess moisture, while infestations may occur due to poor sanitation or building structure issues. Both problems are linked to health concerns like respiratory issues and allergies.
