Do You Need Council Approval for a Pergola in WA?

The general rule

In Western Australia, whether your pergola or patio needs approval mostly comes down to its size, height and whether it has a roof. Small, open structures are often exempt from a building permit, while larger or roofed structures usually need one. The rules sit under WA's building regulations and are applied by your local government (shire or city), so the detail can vary by area.

Often exempt

Smaller, free-standing, unroofed structures below the size and height thresholds in the regulations are commonly exempt from a building permit. Even when a permit isn't required, the structure still has to meet the building standards and be built safely and to boundary/setback rules.

Usually needs a permit

Roofed patios and verandahs, larger structures, anything attached to the house, or builds close to boundaries typically need a building permit (often as a 'Class 10a' structure), and sometimes planning approval as well. Your local shire's building services team is the authority on what your specific job needs.
