Granny Flats in Perth

Do I need planning permission to build a granny flat in Perth?

Yes. Before you build your granny flat, you’ll need to get acquainted with any building and planning regulations for your suburb. We can help you with this, or if you want to conduct your own research you can start with the Residential Design Codes (R-Codes). Your R-Code will dictate how big your block needs to be, the maximum size granny flat you can build and other things that you ought to be aware of, such as parking requirements for example. The planning department of your local council are a good place to start.

We deal with council planning and building departments on a regular basis, so when you hire SOL Construction, we will submit your plans and work with your local council to ensure everything is above board. It’s one less thing for you to worry about.

How do I know how big my granny flat can be?

The largest size granny flat you can build in Perth is 70 m2, however there are a few things you will need to take into account, like the R-Code (zoning) for your block and any council restrictions or requirements, such as the minimum distance from your fence.

R-Codes were put in place to control building developments in Western Australia. Every block has one, and it will dictate how much building you can put on your land.

Can I put more than one granny flat on my block?

In short, no. You can only add one granny flat or ancillary dwelling to your block.

How long does it take to build a granny flat?

That depends. What materials it is made from, how much work is needed to prepare the land, what kind of access there is, what type of interior you choose and the design and layout.

Once building starts, it could take up to 12 weeks.
