You intend to build as an owner-builder and the work is above the registration threshold for this building class.
Outside standard residential zoning, a single house commonly needs development approval against the local planning scheme rather than a deemed-to-comply check.
All permitted building work needs a building permit. Certified applications (with a certificate of design compliance) have a 10 business day decision period; uncertified Class 1/10 applications have 25 business days.
Every build needs a site classification (AS 2870) and wind classification to design footings and tie-downs.
Registered easements, restrictive covenants and notifications can dictate where you may build. A Landgate property interest report can also reveal unregistered interests.
Legal, constructed access to the lot is not confirmed. A crossover permit and possibly an access easement may be needed.
Mapping data comes from Landgate's public location services and Planning WA datasets and is indicative only. The local government and a title search remain authoritative before you commit to a purchase.
