Step 1: Check if you need a permit at all
A freestanding shed of 10 m² or less and no higher than 2.4 m doesn't need a building permit under the state's Building Regulations. It may still need planning approval if it breaks your council's rules, for example by sitting in the front setback. Anything bigger needs a building permit.
Step 2: Check the planning rules
Most councils let a shed skip planning approval if it meets the standard outbuilding rules. At the City of Wanneroo and the City of Melville, for example, that means:
- no more than 60 m² or 10% of the lot (whichever is less)
- walls no higher than 2.4 m and a ridge no higher than 4.2 m
- at least 1 m from side and rear boundaries (Wanneroo asks for 1.5 m once a wall is longer than 14 m)
- not used as a place to live, and not in the front setback
If your shed doesn't fit, you'll need a development application first. At most councils the fee is $147 for work up to $50,000. Use our shed size checker to test your numbers.
Step 3: Get drawings and engineering
Most shed kit suppliers provide plans and engineering certificates for your wind region. You'll also need a site plan (usually at least 1:200) showing the distances to every boundary and building, and elevations (usually at least 1:100).
Step 4: Lodge the application
Homeowners usually lodge a BA2 (uncertified) building permit application with their council. It costs 0.32% of the value of the work (at least $121), plus the $61.65 Building Services Levy for work up to $45,000. Some councils, like Wanneroo, also need a Street and Verge Bond application with every building permit. See how to fill in a BA2.
Step 5: Wait for the permit
Council has up to 25 business days to decide a BA2. If they ask for more information, the clock stops until you reply. Don't start building until the permit is issued.
Step 6: Build and finish
Build to the approved plans. Within 7 days of finishing, lodge a notice of completion (form BA7) with your council.
