Sheds & Garages rules in Casey
Building a shed or garage in Casey? City of Casey applies the Victoria planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Small sheds exempt; most sheds need a building permit
A freestanding shed of 10 m² or less and up to 3 m high needs no building permit, and in a standard residential zone with no overlays no planning permit either. Anything bigger needs a building permit, and an overlay can trigger a planning permit at any size.
Key rules at a glance
| Max floor area (no building permit) | 10 m² |
| Max height (no building permit) | 3 m (single storey) |
| Construction | Freestanding, non-habitable, lightweight |
| Planning permit | Generally not required in residential zones with no overlay |
| Boundary siting | Set by your zone/ResCode; larger sheds must meet siting standards |
| When a building permit is needed | Any shed over 10 m² or 3 m high, or of heavier construction |
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.
