LOOKING FOR A GRANNY FLAT?
Did you know that many granny flats in WA can be built without Development Approval (DA)?
That's right – if your granny flat meets certain requirements, you may be able to skip the planning approval process and move straight to obtaining a Building Permit.
To qualify, the granny flat generally must:
✔ Be built on the same lot as an existing home
✔ Be no larger than 70m²
✔ Comply with setback and height requirements
✔ Meet applicable R-Code requirements
Whether you're looking for extra space for family, guest accommodation, a home office, or an investment opportunity, we can help.
