Cooler months typically coincide with reports of mould in a rental property. While this is usually a minor issue, it can have an impact on the health of some tenants. As such, it requires prompt attention and appropriate action.
Acknowledging this, we wanted to take a closer look at why mould in a rental property can be such an issue. As part of this, we will explore the conditions that encourage mould growth. We will also outline who is responsible for addressing mould issues, and share some information on how to avoid them.
What is mould and where does it grow?
Mould is a type of fungi, which is a class of organism that is classified as neither plant nor animal. Mould feeds itself by breaking down organic matter to release nutrients, which is then absorbs.
While mould is extremely common and can grow anywhere, it prefers areas that are damp and dark. This means that in a rental property, mould is most likely to grow on walls, ceilings, and windowsills. It is often also found on tiles and carpet, and can even grow in insulation and structural materials.
According to some studies, mould is found in around one-third of all Australian homes. As NSW properties are especially humid, mould in a rental property is a particular concern here in Sydney. Especially during the cooler months (May – September), when tenants tend to close up their properties, restricting sunlight and airflow.
Understanding mould at homes?
Mould reproduces by releasing tiny particles into the air. These microscopic spores can become airborne and may cause reactions in some individuals.
For most people, exposure to household mould has minimal health effects. However, those with pre-existing respiratory conditions like asthma might experience mild symptoms. People with weakened immune systems or chronic lung conditions may also notice more pronounced effects.
Who is responsible for managing mould in a rental property?
Preventing the growth of mould in a rental property requires a combination of structural features and ongoing management. Regular monitoring is also required to identify issues early and reduce the risk of property damage and health issues. As such, both tenants and landlords have a role to play, and should work in partnership to manage mould issues.
Generally speaking, tenants are considered primarily responsible, and are required to take reasonable steps to prevent mould growth. This includes:
- ensuring that there is sufficient airflow within the property
- preventing the build-up of moisture
- monitoring the condition of the property
- notifying their landlord if there are signs of mould growth
If a tenant fails to take these steps, they may be liable for any mould removal and repair costs.
Landlords are required to support their tenants by ensuring they have the tools they need to manage moisture levels. This includes making sure that:
- there is adequate ventilation, and tenants are able to create airflow within the property (e.g. windows are openable)
- any maintenance issues that could lead to a build-up of extra moisture are addressed quickly
- any reports of mould growth require prompt attention.
If a landlord fails to provide sufficient means to prevent mould growth, they may be responsible for removal and repair costs.

The dos and don’ts of preventing mould in a rental property
As mould thrives under certain conditions, there are a few simple things you can do to stop its growth. Specifically, mould needs moisture so, to reduce the risk of mould, you should focus on keeping your property dry.
What tenants can do
- Use moisture reducing appliances: Common daily activities, like cooking, bathing, and drying clothes, can add significant moisture to your home’s environment. As such, you should use the installed extractor fans, rangehood, etc. when doing these activities. If moisture build up is a particular issue in your home, you may also want to consider using a dehumidifier.
- Limit moisture creating furnishings: Common household items, like fish tanks and indoor plants, add to the moisture in a property. As such, you should carefully consider the number of these items that you bring into your home.
- Encourage air flow: The movement of fresh air through a property helps to dry it out. As such, you should open your windows whenever the weather allows and, if possible, try to create a cross-breeze.
- Optimise natural light: UV rays have been shown to slow, and even stop, the growth of mould. As such, you should aim to let as much sunlight as possible into your home, particularly during the colder months.
- Monitor for mould growth: Early identification and treatment of mould reduces the risk of spreading. As such, you should keep an eye out for black or brown marks developing on your walls, ceilings, and floors.
- Promptly clean mouldy surfaces: In most instances, if you intervene early enough, mould can be wiped away using common household cleaning products. As such, you should treat mould growth as a matter of priority, using a mild detergent or diluted vinegar solution. If this doesn’t work, try a diluted bleach solution – just make sure you wear protective equipment and only use this solution in a well-ventilated area.
What landlords can do
- Install proper ventilation: Functional exhaust fans and openable windows allow tenants to manage moisture levels and create airflow. As such, you should ensure these are available, particularly in wet areas, like the kitchen, bathrooms, and laundry.
- Promptly repair plumbing problems: Burst pipes, a leaking roof, and blocked gutters increase the risk of flooding and the resulting dampness issues. As such, you should ensure that, if these problems occur, they are addressed as a matter of priority.
- Repair or replace any water damaged materials: If your property floods, impacted materials (flooring, walls, etc.) can retain moisture long after the water has been cleared. As such, you should ensure they are thoroughly cleaned and dried or, if they damaged then consider replacing.
- Waterproof barriers in brick walls: Due to the porous nature of brick, gaps in brick walls are prime breeding grounds for mould. As such, you should ensure they have been correctly treated to prevent rising damp and minimise moisture build up.
- Enable subfloor ventilation: Without sufficient airflow, subfloor spaces also provide the perfect conditions for mould to grow and spread. As such, you should ensure weep holes and air vents are clear and uncovered.
