As property prices continue to climb across Australia and available land becomes increasingly scarce, savvy investors and homeowners are turning to innovative housing solutions to maximise their returns.
While dual occupancy arrangements offer several options, secondary dwellings (commonly known as granny flats) have emerged as the most practical and advantageous solution for most property owners. With lower costs, simpler approvals, and excellent flexibility, secondary dwellings deserve serious consideration in today’s market.
What Exactly is a Dual Occupancy Property?
A dual occupancy property refers to a single block of land that contains two separate dwellings. These can be either attached (sharing a common wall) or detached (two completely separate structures on the same lot). The key distinction is that both dwellings exist on the same land title, though they function as independent living spaces with separate entrances, amenities, and living areas.
Unlike traditional single-dwelling properties, dual occupancies create multiple income streams or living arrangements within a single property investment. In Australia, this approach has gained traction as property values have risen significantly in recent years, driving demand for high-yield investment opportunities.

Types of Dual Occupancy Properties
Dual occupancy properties come in several configurations, each with distinct characteristics:
- Attached Dual Occupancies: These dwellings share a common wall, similar to a duplex arrangement, though with some important legal differences. Both homes remain on a single title and cannot be subdivided.
- Detached Dual Occupancies: These consist of two separate dwellings on the same lot of land without any physical connection between them. This offers greater privacy but typically requires a larger land area.
In both cases, utilities can be separated between the two dwellings, allowing for independent living arrangements or rental situations.
Granny Flats vs Dual Occupancy
The terms “granny flat” and “dual occupancy” are often used interchangeably, but there’s an important technical difference between them. A granny flat is classified as a secondary dwelling, which is a self-contained accommodation built on the same land as the primary residence.
In contrast, dual occupancy properties consist of two primary dwellings, neither of which is considered secondary to the other. This distinction has implications for approvals, regulations, and how the properties can be used.
Secondary Dwellings
Secondary dwellings (including granny flats) are:
- Established in conjunction with a principal dwelling
- Built on the same lot of land
- Can be located within, attached to, or separate from the principal dwelling
The term “granny flat” falls within the definition of a secondary dwelling, and these terms are often used interchangeably.
In some Australian states like NSW, regulatory amendments have simplified the process, potentially removing the need for council approvals if certain criteria are met.
Why Secondary Dwellings Outperform Dual Occupancy Investments
1. Faster, Simpler Approvals
Secondary dwellings benefit from streamlined approval processes in many jurisdictions:
- Complying development pathways can fast-track approvals
- Less onerous requirements compared to full dual occupancy developments
- Reduced planning complexity means faster time to market
Dual occupancy developments, by contrast, usually require comprehensive development applications that can take months or even years to approve, with no guarantee of success.
2. Lower Initial Investment
Secondary dwellings typically cost significantly less to construct than full dual occupancy developments:
- Smaller footprint means reduced material costs
- Less extensive service connections required
- Simplified construction process
- Lower professional fees for design and planning
This reduced capital outlay improves the overall return on investment and reduces financial risk.
3. Excellent Rental Returns
Despite the lower initial investment, secondary dwellings can deliver impressive rental yields:
- Can add approximately one-third extra to an investment property’s rental income
- Often achieve higher per-square-meter rental rates than the primary dwelling
- Appeal to a wide range of tenants seeking affordable, private accommodation
4. Flexible Living Arrangements
Secondary dwellings offer remarkable flexibility for owners. You could:
- Live in one dwelling while renting the other for passive income
- Accommodate extended family members while maintaining privacy
- Use the secondary dwelling as a home office or guest accommodation
- Convert to short-term accommodation like Airbnb when suitable
This versatility makes secondary dwellings particularly attractive in Australia’s current housing market, where affordability challenges and changing family structures are driving demand for alternative living arrangements.
5. Meeting Growing Demographic Trends
Currently, one in five Australian households contains two generations, and approximately 10 per cent contain three generations. These figures are expected to rise to around 25 and 15 per cent, respectively, within the next decade. Secondary dwellings provide the perfect solution for this demographic shift while avoiding the complexities of full dual occupancy arrangements.
