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.

Depends on your lot

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.

Casey: assessed by City of Casey under the Victoria rules below.
Approval pathway: Two separate approvals in Victoria: a building permit (structural and safety, issued by a private or council building surveyor) and a planning permit (land use, issued by council). Sheds of 10 m² or less and 3 m or lower are exempt from a building permit under Schedule 3 of the Building Regulations 2018; larger sheds need one. A planning permit is usually not required in residential zones unless a heritage, bushfire (BMO), flood (LSIO/SBO) or environmental overlay applies.
