Regulator: Building and Energy

Which NCC edition applies

NCC 2025 took effect on 1 May 2026. During the 12-month transition to 1 May 2027, NCC 2022 may still be used.

Building permits

Most building work needs a building permit from the local government, either certified by a private building surveyor or assessed by the council's surveyor.

Source

No mandatory stage inspections for houses yet

Unlike most states, WA doesn't currently require mandatory stage inspections for Class 1 houses. Reforms start with high-rise apartments and commercial buildings, and houses will only be included after a review.

Source

Licensed plumbing and electrical work

Plumbing work needs a licensed plumbing contractor with notices to the Plumbers Licensing Board, and electrical work needs a licensed electrical contractor with notices and certificates under the Electricity (Licensing) Regulations 1991.

Source

Workmanship tolerances

The WA Guide to Standards and Tolerances sets the expected finish for common defects such as wall straightness, cracking and tiling.

FAQ

Do I need a frame inspection in WA?

Not by law for a Class 1 house at the moment, but your building surveyor, contract or lender may require one, and it's good practice before lining.

Source

Who regulates builders, plumbers and electricians in WA?

Building and Energy, which supports the Building Services Board, the Plumbers Licensing Board and the Electrical Licensing Board.
