Granny Flats rules in Brisbane
Building a granny flat in Brisbane? Brisbane City Council applies the Queensland planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Often accepted development, but many councils require assessment
Yes. Many Queensland councils treat a compliant secondary dwelling as accepted development that needs no planning approval, and since 2022 you can rent it to anyone. Size limits are set by your local planning scheme.
Key rules at a glance
| Maximum floor area | Varies by council - commonly up to 80 m² |
| Approval type | Often accepted development (no approval) |
| Can it be rented? | Yes - to anyone (since Sept 2022) |
| Location | Same lot as, and subordinate to, the main house |
| Setbacks / siting | Set by the local planning scheme |

Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
