Granny Flats in Western Australia

Rentable, Flexible, and Council-Compliant Granny Flats Across WA

Prestige Kit Homes designs and supplies customisable kit granny flats in Western Australia, helping homeowners across Perth and regional WA build compliant, versatile secondary dwellings for family use or rental income.

Thanks to recent changes in WA legislation, granny flats are now easier to rent out, offering new opportunities for homeowners to unlock income, support loved ones, or provide affordable housing options.

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.

What Are the Rules for Building a Granny Flat in WA?

Western Australia’s current granny flat regulations aim to provide greater flexibility for homeowners while maintaining planning standards. Here’s a summary of the key requirements:

General Regulations:

  • Only one primary dwelling and one granny flat are permitted per lot

  • The granny flat must be self-contained

  • It may be rented out to anyone, not just family members

Design & Planning Criteria:

  • Maximum size:

    • Up to 70m², or

    • A larger size if permitted by your local council

  • Must meet local planning codes, including:

    • Setbacks

    • Site coverage

    • Open space requirements

    • Density allowances

  • Compliant with the Building Code of Australia (BCA)

Note: Rules can vary slightly depending on your local government area (e.g., Perth, Fremantle, Mandurah, Busselton). Always check with your local council before submitting a development application or building approval.
