Granny Flats rules in Moreton Bay
Building a granny flat in Moreton Bay? City of Moreton Bay 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 |
| Building approval | Always required |
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.
How often this applies in Moreton Bay
These are the overlays that can remove the fast-track, measured across every parcel in Moreton Bay from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | 0.06% | 104 parcels flagged. The rest are mapped and sit outside it. |
| Flood | 0.32% | 577 parcels flagged. 99.68% of the council carries no flood mapping at all — unassessed, not cleared. |
| Bushfire | 21.5% | 38,719 parcels flagged. The rest are mapped and sit outside it. |
The most common zone in Moreton Bay is General residential, covering 69.2% of its 180,123 parcels. What you can build is decided by your own lot's zone, not the council's most common one.
