Why Brisbane backyards are earning their keep
Rent to anyone since 2022
Queensland changed the rules on 26 September 2022: secondary dwellings can now be rented to people outside your household. A well-built granny flat is a legitimate income-producing asset, not just a spare room.
Keep family close
Ageing parents, adult kids saving a deposit, or a returning family member: a self-contained granny flat gives everyone independence on the one block, without strata, body corporate or a second mortgage-sized land purchase.
Add value, not just space
Brisbane rents remain strong and quality granny flats typically rent quickly. Depending on suburb and spec, weekly rents of several hundred dollars are common - see our honest numbers on the investment page.

Get matched with a licensed builder
We connect you with a licensed, insured Brisbane builder who works in your area and builds at your budget. They contact you to arrange a free site assessment.
Free site assessment and quote
The builder walks your block, flags anything that affects cost (slope, access, services, overlays) and gives you a written quote. No cost, no obligation to proceed.
Approvals and build
Your builder and a private certifier handle building approval and any council requirements. Most granny flat builds take around 12 to 16 weeks on site once approved.
