Episode notes
Wait Until Rules Take Effect
- Do not start building yet because the new granny-flat rules only take effect after an Order in Council, expected early 2026.
- Get building professionals involved early since the exemption still requires licensed practitioners and paperwork.
Use Licensed Professionals
- Use licensed building practitioners (LBPs) for design and construction because the scheme relies on professional oversight.
- Avoid DIY or unlicensed work since LBPs hold liability and supervise restricted building work.
Core Design Limits
- The granny flat must be simple, new, single-storey, and comply with the Building Code.
- Maximum internal area is 70 m², max height ~4 m, and floor no more than 1 m above ground.
