Mould in Your Rental Property? Know Your Rights in Tasmania

Landlord Obligations Under Tasmanian Law

Under the Residential Tenancy Act 1997 (Tasmania), landlords are required to maintain rental properties in a reasonable state of repair and ensure they are fit for habitation. Persistent mould caused by structural issues — such as leaking roofs, poor drainage, or inadequate ventilation — is generally the landlord’s responsibility to address.

When Is Mould the Landlord’s Responsibility?

Mould is typically the landlord’s responsibility when it results from:

  • Structural defects such as leaking pipes, roofs, or walls
  • Inadequate ventilation (e.g., no exhaust fans in wet areas)
  • Rising damp or subfloor moisture issues
  • Faulty or missing insulation
  • Poor building design or construction defects

When Is Mould the Tenant’s Responsibility?

Tenants are expected to take reasonable steps to prevent mould, including:

  • Using exhaust fans when cooking and showering
  • Opening windows regularly to ventilate
  • Not drying clothes indoors without adequate ventilation
  • Reporting leaks and maintenance issues promptly
  • Wiping down condensation on windows

Steps to Take if You Have Mould

  1. Document the mould with photos and dates
  2. Report the issue to your landlord or property manager in writing
  3. Allow reasonable time for the landlord to arrange repairs
  4. If the landlord fails to act, contact Consumer, Building and Occupational Services (CBOS)
  5. Consider applying to the Residential Tenancy Commissioner if the issue remains unresolved
