AI summary

New rules make building a granny flat easier by removing consent requirements for standalone units up to 70sqm.

To qualify, the build must meet specific criteria, including being single-storey and using lightweight materials. All work must be supervised by Licensed Building Practitioners (LBPs).

While this can save up to $5,650, you must get a Project Information Memorandum (PIM) before starting. Be aware that councils can still charge significant Development Contributions, so check with them early in your planning process.
