Know what you can build — before you call a builder.
Enter any Australian address for live zoning, planning overlays and development controls — straight from government data. Free, instant, every state.
Look up the rules for your project
Every state sets different rules for what needs approval. Pick a project for a clear, sourced answer — then check your exact address for the overlays that can change it.
Granny flats
Secondary dwelling size limits, minimum lot sizes, whether you can rent it out, and if you need a DA — for all 8 states.
See the rules →Decks & pergolas
The height and area thresholds that decide whether a deck, pergola or verandah needs a building permit or council approval.
See the rules →Sheds & garages
How big a shed or garage you can build without approval, boundary setbacks, and the metro-vs-rural size limits per state.
See the rules →Fences
How high you can build a fence without approval, front vs side and rear limits, pool-fence rules, and when your neighbour must share the cost.
See the rules →Subdivision
What decides whether you can split a block — minimum lot size, frontage and servicing — plus the approval process in each state.
See the rules →Dual occupancy
Building two dwellings on one lot — where it is permitted, the lot size and frontage you need, and whether you can subdivide afterwards.
