Building Commission NSW

We are the new regulator of the building industry in NSW.

Building Commission NSW is a new, fit-for-purpose building regulator bringing together teams from NSW Fair Trading and the Office of the Building Commissioner into one, to provide an integrated and consistent approach to ensuring confidence in residential building quality in NSW.

Building and construction related work areas of NSW Fair Trading are being transitioned to the newly established Building Commission NSW. These areas include:

  • Inspections and compliance
  • Licensing
  • Complaints
  • Policy

Building Commission NSW is central to rebuilding trust and capability in the construction sector and delivering on the NSW Government’s housing commitments. 

Our team operates across NSW, in both metropolitan and regional areas. We are based where homes are being built to ensure that compliance is carried out on a regular basis.

From 1 December 2023, the Building Commission NSW will take on the role of regulator of the building and construction industry in NSW. This means over the coming months you may notice some changes.

What we do

Building Commission NSW oversees and regulates the NSW construction industry. Under the leadership of David Chandler OAM, the NSW Building Commissioner, our key areas of focus are:

Building industry capability

Through data, intelligence and analytics, inspections, licensing and accreditation and enforcement activities.

Proactive regulation and industry collaboration

Leading the charge in proactive policy and regulation, research, education and professional development, industry led-initiatives and engagement.

Changes to building legislation in NSW

Several amendments have been made to building legislation as part of ongoing reforms to transform the regulation of the construction industry and restore trust and confidence in residential buildings. Read more
