When it comes to renting a property in New South Wales (NSW), it’s essential to know your rights and responsibilities as a tenant. One of the concerning issues that often occur in rental properties is the growth of mould. Mould can cause health problems and affect the quality of the indoor environment, so it’s vital to address the issue as soon as possible. In this article, we’ll discuss the NSW tenancy agreement and mould, including what tenants, landlords, and property managers need to know.

What is a NSW tenancy agreement?

A NSW tenancy agreement is a legal document that outlines the terms and conditions of a rental property. It can be a written or verbal agreement and can be for a fixed-term or periodic lease. As a tenant, you’ll be required to sign the tenancy agreement before moving into the property. It’s essential to read the agreement thoroughly and understand your rights and obligations as a tenant.

How does the NSW tenancy agreement regulate mould?

The NSW tenancy agreement requires landlords to ensure that the property is in a reasonable state of cleanliness and fit for living. This includes the prevention and removal of mould. If the property already has mould before the tenant moves in, the landlord is responsible for removing it before the tenant moves in. If mould grows during the tenancy, the tenant should notify the landlord or property manager as soon as possible.

The landlord must take appropriate steps to remove the mould, such as repairing any leaks or ventilation issues that may be causing the problem. Failure to address the issue can lead to breaches of the tenancy agreement and potential legal action against the landlord.

What should tenants do if they discover mould?

If you’re a tenant in a rental property and you discover mould, it’s essential to notify the landlord or property manager immediately. You can do this by sending a written notice or email outlining the issue. The landlord must respond to the notice within a reasonable time frame and take action to remove the mould.

In some cases, the landlord may deny responsibility for the mould, claiming that it’s caused by the tenant’s actions, such as not ventilating the property or using a clothes dryer. In such cases, it may be necessary to seek legal advice or contact the NSW Tenancy Tribunal.


Mould can be a significant problem in rental properties, but tenants can take action to protect their health and wellbeing. By understanding their rights and responsibilities under the NSW tenancy agreement, tenants can ensure that landlords take appropriate steps to prevent and remove mould. If you’re a tenant and you discover mould in your rental property, don’t hesitate to notify the landlord or property manager and take action to address the issue.
