Build a Backyard Home: Downsize Without Leaving Your Street
Your block may be worth more than the house on it. A backyard home, a granny flat or a dual occupancy can let you downsize, stay in the area you love and free up equity.
Here are the options, the 2026 planning rules and how to know what your block can take.
Five Ways to Use Your Land
Moving to an apartment or out of the suburb is not the only way to downsize. Many family homes sit on blocks that can take a second dwelling, or be split in two. That opens up options most people never consider:
- Build a backyard home and stay. Live in a brand new, low-maintenance home and rent out the main house, or let family move in.
- Build and subdivide. Sell the original home on its own title and keep the back block, with cash left over.
- Knock down and rebuild two. Replace the house with a duplex or dual-key home: live in one, sell or rent the other.
- Develop the block. Three or more townhouses, or a boutique apartment project on larger or well-zoned sites.
- Sell to a developer. If you would rather not build, a block with development potential can fetch more than its market value.
Do I Need to Subdivide?
A granny flat that you keep on the same title does not need a subdivision. You need planning and building approval, and then you can live in it, rent the main house or house family.
If you want to sell part of the land, you need a subdivision so each home has its own title. That takes longer, costs more and depends on lot size, zoning and services.
Granny flat, no subdivision
- Faster and cheaper to approve
- One title, one owner
- Rent the house or the flat
- Equity stays in the property
Subdivide and sell
- Two titles, can sell one
- Releases cash now
- Council, survey and service costs
- Minimum lot sizes apply
What the Planning Rules Now Allow
Recent planning changes have made second dwellings easier in several states:
- Victoria: since 14 December 2023 a small second dwelling of up to 60m² generally needs no planning permit on most residential lots, though a building permit is still required.
- Queensland: since 2022 secondary dwellings can be rented to people outside the household, not just family.
- New South Wales: secondary dwellings of up to 60m² can often be approved as complying development.
Every council, zone and overlay is different. Heritage, flooding, bushfire, easements and the shape of the block all matter.
