Granny Flats

Exciting news for homeowners and property investors in the City of Kwinana – a recent planning change has made it significantly easier (and faster) to build a granny flat on your property.

The Minister for Planning has approved Amendment 165 to the City of Kwinana’s Local Planning Scheme No. 2 (LPS2), removing the need for development approval for an ancillary dwelling (granny flat) — as long as it complies with the Residential Design Codes (R-Codes) and any relevant Local Development Plan.

What this means for property owners

This amendment simplifies the approval process for compliant granny flats by removing the need for a formal development application. It’s a practical step that can reduce timeframes, minimise costs, and remove barriers to starting your build.

Whether you’re looking to:

  • Create space for extended family,
  • Unlock passive income through rent, or
  • Or add long-term value to your property.

Now is the perfect time to build a Summit Granny Flat.
