Shed & garage rules in Canberra
ACT Government (Territory Plan) assesses these under the Australian Capital Territory rules below. Heritage, flood or bushfire mapping on your own lot can change what you need to apply for.
DA-exempt within limits, but building approval still needed
A Class 10a shed can be 'exempt development' — no development application (DA) — if it's within the size, height and siting limits (up to 20 m² in residential zones, more in rural zones). But in the ACT you still need a separate building approval for most sheds.
Key rules at a glance
| Max plan area (exempt, residential) | 20 m² |
| Max plan area (exempt, rural RU zones/R5) | 50 m² (up to 216 m² for genuine rural landholders) |
| Max height | 3 m above datum ground (up to 4 m under a 30° plane from the boundary) |
| Position on lot | Behind the front building line |
| Boundary clearance | Within 1.5 m of a boundary, combined wall cross-section ≤30 m² |
| Building approval | Still required separately for most sheds, even if DA-exempt |
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.
