Where are building disputes heard for Perth?
Complaints about building work and home building contracts are made to the Building Commissioner, whose office sits within Building and Energy, part of the Department of Local Government, Industry Regulation and Safety. Building Commissioner orders can be reviewed by the State Administrative Tribunal (SAT) if an application is filed within 28 days, and some unresolved complaints are referred to SAT. Large commercial construction disputes are heard in the District Court or the Supreme Court of Western Australia.
What Western Australian rules apply?
The Building and Construction Industry (Security of Payment) Act 2021 (WA) applies to contracts entered into from 1 August 2022, and the Construction Contracts Act 2004 (WA) still applies to earlier contracts. Home building contract disputes can be taken to the Building Commissioner for contracts valued between $7,500 and $500,000. A complaint about building work generally cannot be considered more than 6 years after the work was completed.
How much does a construction lawyer cost in Perth?
