RETROSPECTIVE BUILDING APPROVALS & UNAUTHORISED BUILDING WORK – PERTH WA 

• Work Completed Without Approval

• Retrospective or unauthorised construction refers to building work carried out without the required Building Permit or Development Approval from the local authority.

Common Examples

• This may include carports, garages, extensions, swimming pools, granny flats, internal alterations, commercial fit-outs, or changes of use completed without proper approval.

Compliance Assessment Required

• To regularise the works, the building must be assessed against the National Construction Code (NCC) and relevant standards to determine whether it complies or requires rectification.

Retrospective Approval Process

Where required, a Certificate of Building Compliance (BA18) and supporting documentation may be necessary to satisfy local government requirements and address any Building Order or compliance notice.
