Do I need council approval for a granny flat in WA?
Not always, but you may still need to deal with your local government.
Since 10 April 2024, compliant granny flats in WA can be built on residential lots of any size without planning approval, if they meet the relevant deemed-to-comply requirements, local setback rules, and do not exceed 70m². However, you still need a building permit from your local government, and the design must comply with the National Construction Code. The WA Government also advises owners to contact their local council to confirm whether the exemption applies to their site.
How does that compare to a traditional 2-bedroom home in Perth?
This is where a granny flat starts to make a lot of sense.
One Perth building cost guide estimates that a traditional 2-bedroom house in Perth costs around $276,000 to $534,000 to build, based on a 120m² home. The same guide also notes that new 2-bedroom houses are relatively uncommon in Perth and are more often villas, townhouses or custom builds.
Compared with that, a two-bedroom granny flat is usually smaller, simpler, and aimed at a different purpose. You are not necessarily building a full-size family house. You create practical secondary accommodation, often at a lower entry cost and with a much smaller footprint.
What affects the price?
The following factors have the biggest influence on cost:
- total floor area
- number of bathrooms
- transport distance
- site access
- foundations and site works
- utility connections
- patios, decks and outdoor areas
- upgrades to finishes, storage, kitchen or laundry layout
Two buyers can both ask for a 2-bedroom granny flat and end up with very different costs depending on how they choose to customize their cabin.
