Q: <strong>Do all Perth suburbs allow granny flats? 🏡</strong>

Not all of them. Your suburb needs an R20 zoning or higher before a granny flat qualifies. Most of Perth's inner and middle-ring suburbs meet this standard. Some outer or semi-rural areas sit below R20 and generally miss out, though a few exemptions exist. Always check your specific address on your council's planning map before you start designing.

Q: <strong>How do I find out which council area my property is in? 🗺️</strong>

Search your property address on the WA Landgate site or your local council's website. This usually shows your exact council area and zoning. Knowing your council early matters, as it decides which local guidance and approval process applies to you on top of the state R-Codes.

Question 1

Do all Perth suburbs allow granny flats? 🏡

Accepted Answer

Not all of them. Your suburb needs an R20 zoning or higher before a granny flat qualifies. Most of Perth's inner and middle-ring suburbs meet this standard. Some outer or semi-rural areas sit below R20 and generally miss out, though a few exemptions exist. Always check your specific address on your council's planning map before you start designing.

Question 2

Does every Perth council have the same granny flat rules? 🏛️

Accepted Answer

They share the same state R-Codes, but each council can add its own local planning conditions. These might cover privacy, fencing, or specific design details. Councils like Stirling and Wanneroo publish their own guidance pages alongside the state rules. Always check both the state requirements and your own council's local planning scheme.

Question 3

Can I build a granny flat on a small block in Perth? 📐

Accepted Answer

Often, yes, thanks to a 2024 reform. WA removed the old 450m² minimum lot size for granny flats up to 70m². That opened the door for smaller blocks across Perth. Your zoning still needs to be R20 or higher, so confirm that first before assuming your block now qualifies.

Question 4

How do I find out which council area my property is in? 🗺️

Accepted Answer

Search your property address on the WA Landgate site or your local council's website. This usually shows your exact council area and zoning. Knowing your council early matters, as it decides which local guidance and approval process applies to you on top of the state R-Codes.

Question 5

Do I need to contact my council before designing my granny flat? 📞

Accepted Answer

It's not always required, but it's strongly worth doing. A short call or email can confirm your zoning, flag any local overlays like heritage or flood areas, and clarify your council's approval steps. This early check often saves weeks of delay and costly redos later.
