How dual occupancy can maximise your property’s potential

 In Conveyancer, First Home Buyer

Dual occupancy is where there are two dwellings on one piece of land.  

Having dual occupancy can be a great option if you want to maximise your land value or bring in potential rental profit. Aside from these clear benefits, it’s important to know that having more than one dwelling on your land has certain technicalities and considerations.  

We’re here to share our expertise in the area and answer the most frequently asked questions we get from our clients who are considering dual occupancy. 

What is dual occupancy? 

The NSW State Government defines dual occupancy as ‘two dwellings on one title, either attached or detached’. 

An attached dual occupant property is two homes on the same parcel of land that are connected/joined by a wall that usually extends the full length of the house. An example of this is a duplex.  

A detached dual occupant property still has two homes on the same parcel of land but the dwellings stand separately from one another.  

Dual occupancy rules differ from a secondary dwelling or a granny flat as it’s treated as an extension of the primary dwelling and can NOT be subdivided. 

Dual occupant properties are generally two separate primary households, and each home will ordinarily have a dedicated entrance, amenities and yard. 

Can it by subdivided? 

Yes! But subject to Council approval. A dual occupancy subdivision is definitely achievable for both attached and unattached dwellings and can be divided into either a strata or a Torrens title. 

Strata titles allows for ownership of property that’s adjoining in some way like an apartment, unit or townhouse because they share common areas such as roofs, gardens and driveways. Whereas a Torrens title means you own the land and the building that sits on it. 

Why should I consider dual occupancy? 

Dual occupancy home designs are becoming more popular amongst homebuyers who want to maximise their income, downsize or increase the value of their property. 

Increase the value of a property 

According to We Build Australia, there is potential for properties to increase their value by up to 40% if subdivision can be achieved, because you’re essentially doubling your sellable assets. 

Additional source of income 

If you decide to keep the land under one title, you’re saving money by paying one set of rates while potentially collecting two lots of rent.  

Owning two dwellings on one piece of land means you can either live in one and rent out the other or rent out both, providing solid rental income.  


For potential homeowners, attached dual occupancies and duplexes are a great way to get your foot in the door of the property market. Buying one side of a dual dwelling can be the first step in setting yourself up financially to upgrade in the future. 

Where do I start? 

Before making any plans to build a dual occupancy your first step is to contact your local council to ensure your plans fit within your council’s Local Environmental Plan (LEP). Plans will also need to comply with the Development Control Plan (DCP), which are the planning and design guidelines that support the LEP.
