Rules
Council rules are checked against the official wording. Whether a granny flat is allowed depends on the council and state, and so far few councils are checked. Not checked does not mean not allowed.
Checked, dated, sourced

Costs
The cost tool covers delivery, site work, connections, approvals and insurance around the build price. Its figures are ranges until you replace them with quotes.

Builders
Builders are listed once we have checked who they are and whether they operate. The directory is not yet broken out by granny flat work.
No granny flat models are listed yet
A model appears with a dated price, GST basis and build stage, or marked price on request. State-by-state granny flat rules are still being researched.
