You’ll learn when a landlord is responsible, how to document issues, and practical prevention tips to reduce moisture and improve air flow in rental units across New Brunswick.
Who is responsible for mold and ventilation?
Under New Brunswick tenancy rules, landlords must provide and maintain a rental unit that is habitable and reasonably free from hazards like mould and unsafe ventilation. Tenants must take reasonable steps to avoid creating excess moisture (for example, using bathroom fans and reporting leaks promptly). When a condition is beyond tenant control — such as building envelope problems, faulty HVAC, or chronic leaks — the landlord is generally responsible to repair and remediate.
Common landlord duties and tenant steps
Key duties and practical tenant actions include:
- Landlord must repair leaks and faulty ventilation systems promptly to prevent mold growth.
- Provide access for inspections and repairs when given reasonable notice and a lawful reason.
- Tenant should document the issue: photos, dates, times, and any health symptoms possibly related to mold.
- Serve written requests for repairs or remediation so there is a clear record for both parties.
- Landlord must use qualified contractors for major mold remediation and provide follow-up after repairs.
When ventilation is the issue
Poor ventilation can cause condensation and encourage mould. Landlords should ensure mechanical systems (exhaust fans, heat recovery, HVAC) work as intended and that windows and vents are not blocked. Tenants should use available ventilation, report broken fans, and avoid practices that increase indoor humidity (like drying large loads of laundry inside without ventilation).
Reporting, repairs and formal remedies
If the landlord does not fix a serious mold or ventilation problem after you report it in writing, tenants in New Brunswick can apply to the provincial tribunal to request orders for repairs or rent abatement. Before filing, collect all evidence and copies of written requests.
Official forms and provincial contacts
Key official resources include the Residential Tenancies Tribunal and the provincial legislation. Tenants often use an application form to ask the tribunal for an order requiring repairs or compensation. Example official resources below link to the tribunal and the act for details and forms.[1][2][3]

FAQ
- Who pays for mold remediation in a rental?
- The landlord must pay for remediation when mold results from building defects, leaks, or inadequate ventilation; tenants should not be charged for repairs caused by structural or system failures.
- What if my landlord doesn’t respond to my repair requests?
- Document your written requests, keep photos and receipts, and you can apply to the Residential Tenancies Tribunal for an order for repairs or compensation.
- Can I withhold rent if there is mold?
- Withholding rent is risky and not recommended; instead, follow the tribunal process to seek remedies and avoid self-help measures that may breach your lease.
How-To
- Inspect and document the problem clearly with dated photos and notes describing where and when the mold appears.
- Collect evidence of repair requests and health impacts, such as messages to the landlord and any medical notes if applicable.
- Serve a written request for repairs to your landlord and keep a copy for your records.
- Allow reasonable access for inspection and remediation once proper notice is given, while insisting on qualified remediation for serious mold.
- If the landlord does not act, file an application with the Residential Tenancies Tribunal using the official form.
