Improving building regulation

Audit class 1 building constructions

We audit class 1 buildings to provide confidence in the quality and safety of the residential building industry in NSW. 

Regulate class 2, 3, and 9c

We enforce and regulate building work on class 2, 3 and 9c buildings. Practitioners must register and declare compliance to meet industry standards.

Enforce stop work orders

To ensure safety and compliance, we issue prohibition, stop work and building rectification orders to fix serious defects or non-compliance in residential buildings. 

Fix building defects

We ensure the fixing of serious defects in class 2 residential buildings by issuing orders and negotiating agreements, including Developer Undertakings, between developers and owners. 

Project Intervene

Project Intervene helps owners corporations get their serious building defects resolved through a structured and efficient process. Registrations are now closed.

Perform audits

By auditing developers, certifiers and building practitioners, we provide confidence, quality, safety and trust in residential construction before issuing an occupation certificate.
