Sheds & Garages rules in Wanneroo
Building a shed or garage in Wanneroo? City of Wanneroo applies the Western Australia planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Often no planning approval; a building permit for most sheds
A single prefabricated shed of 10 m² or less and up to 2.4 m high needs no building permit. Bigger outbuildings need a building permit, but avoid planning (development) approval if they meet the R-Codes 'deemed-to-comply' outbuilding rules — behind the street setback and within the size, wall-height and setback limits.
Key rules at a glance
| Max area (no building permit) | 10 m² prefabricated shed, ≤2.4 m high |
| Max aggregate area (R-Codes deemed-to-comply) | 60 m² or 10% of the site, whichever is less |
| Max wall height | 2.4 m |
| Max ridge height | 4.2 m |
| Boundary setback | ≥1 m (≥1.5 m for longer walls); no more than two walls within 600 mm of a boundary |
| Position on lot | Behind the street (front) setback line |
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.
