Why Build a Granny Flat in WA?

Recent updates to WA’s planning laws have made it easier than ever to build and rent out a granny flat, no longer restricting occupancy to family members only. These changes offer significant benefits:

  • Rental income from students, seniors, or single tenants

  • Affordable living space for adult children or carers

  • Downsizing options for empty nesters, with income potential

  • Flexibility and equity for WA property owners

  • Increased property value and usability

Granny flats in WA are now allowed in all residential zones, subject to meeting relevant planning and design criteria.
