Since 2020, the DBP Act and RAB Act have applied to buildings containing a class 2 part, being residential apartment buildings. Those Acts are a key component of the NSW Government's building industry reforms. The new Regulation amends provisions relating to class 2 buildings, and extends the reforms to buildings containing a class 3 or 9c part.

All developers, owners, builders, consultants, financiers and certifiers involved in class 3 or 9c buildings must familiarise themselves with their obligations under the DBP Act and RAB Act, and take steps now to adjust their procurement processes.

Key changes

Class 3 and 9c buildings – DBP Act

• From 3 July 2023, the DBP Act applies to work on buildings containing a class 3 or 9c part. That covers boarding houses, hostels and aged care, among others, and includes mixed use buildings if they contain a class 3 or 9c part.
• All people working class 3 and 9c buildings should familiarise themselves with the requirements of the DBP Act. Read our articles on NSW building regulations due to commence on 1 July 2021 have been released and The next phase of NSW building reforms: Decennial Liability and assorted changes.
• There is a grace period for work involving alterations, additions, repair, renovation or protective treatment of buildings containing a class 3 or 9c part where no part of the building is class 2. For that work, the DBP Act applies from 1 July 2024.
• The transitional provisions include that:

• if building work is the subject of a construction certificate or CDC and commenced before 3 July 2023, then the work is exempt from the registration and declaration regime in the DBP Act, but the builder must lodge copies of all designs on the NSW Planning Portal before an occupation certificate is applied for;
• if design work was prepared before 3 July 2023, there is a construction certificate or CDC in place, and the building work is to commence between 2 July 2023 and 3 July 2024 - if the designer is not eligible to be registered then another designer can certify compliance with the Building Code of Australia in some circumstances;
• if work does not require a CDC, construction certificate, development application and occupation certificate, and was carried out before 3 July 2023, but the project is not complete, then the work is exempt from the registration and declaration regime in the DBP Act, but the builder must lodge copies of all designs on the NSW Planning Portal before completion of the project.

• In relation to Sydney Metro building work, there are amendments to align with the above.

Class 3 and 9c buildings – RAB Act

• From 3 July 2023, the RAB Act applies to buildings containing a class 3 or 9c part. That includes mixed use buildings if they contain a class 3 or 9c part.
