Understand the new obligations for professionals working on Class 2 Buildings—the changes that you should be aware of, who needs to register, and how to comply with it.
The Design and Building Practitioners Act (D&BP Scheme) came into effect on July 1, 2021, and it sets new obligations for professionals who work on Class 2 buildings in New South Wales, Australia. As part of the reform of Construct NSW, changes have been implemented in the residential building industry to restore consumer confidence and ensure that the apartments being built are of high standard. It imposes a duty of reasonable care on builders, designers, and suppliers in order to avoid economic damage caused by building defects.
The D&BP Scheme is composed of three main parts: the Design and Building Practitioners Act 2020 (the D&BP Act), the Design and Building Practitioners Regulation 2021 (the D&BP Regulation), and the Ministerial Order 2021.
The D&BP Scheme applies to buildings that are Class 2, or contain a Class 2 component. According to the Building Code of Australia Building Classifications, Class 2 Buildings are:
“A building containing 2 or more sole-occupancy units each being a separate dwelling.”
This category includes multi-unit residential buildings or apartments in which residents live above or below one another, as well as single-story attached residential buildings with a common space below (residential above a common car park).

While Class 2 buildings were identified as the highest priority, the NSW Government intends to expand the extent of the reforms to include other types of construction in the future.
There are a number of key changes to be aware of with this reform, namely:
Part of the residential building industry reforms are two new registration schemes for Class 2-related work—Registration of professional engineers and Compliance Declaration Scheme for Design and Building Practitioners (D&BP). As listed by the NSW Government, below are the professionals who need to register:
Engineers who undertake professional engineering for a Class 2 building, or a building that contains a Class 2 component must be an individual, not a corporation, in order to be recognized.
Professional engineers who need to register under the D&BP Scheme:
Civil engineers
Electrical engineers
Fire safety engineers
Geotechnical engineers
Mechanical engineers
Structural engineers
Compliance Declaration Scheme for Design and Building Practitioners is intended for design practitioners, building practitioner, and principal design practitioner. D&BP need to register before they can declare or lodge documents. The below further specifies who they are:
a) Design practitioners are those who prepare a regulated design for a Class 2 Building, or a building that contains a Class 2 component.
Classes of design practitioner:
Architectural design practitioner
Body corporate design practitioner
Building (lowrise) design practitioner
Building (medium rise) design practitioner
Civil engineering practitioner
Drainage design practitioner
Drainage (restricted) design practitioner
Electrical engineering practitioner
Façade design practitioner
Fire safety engineering design practitioner
Fire systems (detection and alarm systems) design practitioner
Fire systems (fire hydrant and fire hose reel) design practitioner
Fire systems (fire sprinkler) design practitioner
Fire systems (mechanical smoke control) design practitioner
Geotechnical engineering design practitioner
Mechanical engineering design practitioner
Structural engineering design practitioner
Vertical transportation design practitioner
b) Building practitioners are those who are responsible for making building compliance declarations.
Classes of building practitioner:
Building practitioner – body corporate
Building practitioner – body corporate nominee
Building practitioner – general
c) Principal contractors are responsible for making building compliance declarations and lodging documents for submission to the NSW Planning Portal. They are those who undertake building work on Class 2 buildings, or structures that contain Class 2 components.
Classes of principal design practitioner:
Principal design practitioner – body corporate
Principal design practitioner – general
These changes are being implemented to guarantee that buildings are safe and secure, that the industry is more customer-focused, and that better data is collected throughout the building life cycle.

For Class 2 building work, there are new requirements for registered people to declare:
Certain designs need to be declared by a registered design practitioner, in compliance with the Building Code of Australia and other relevant standards, before building work can start, and;
A building compliance declaration (made by a registered building practitioner) specifies that building work is constructed in accordance with compliant designs and in compliance with the Building Code of Australia.
As explained by the NSW Government, regulated designs include plans, specs, and reports detailing a design. These are the designs prepared for a building element or a performance solution intended for building work. Building work refers to the construction, alteration, addition, repair, renovation, or protective treatment of a Class 2 building.
They must be lodged before building work commences to ensure that the building practitioner has all critical designs. Practitioners are also required to rectify design issues before construction begins—saving everyone involved time and money as well as meeting customer expectations. This is a solution tailored to meet the requirements in the Building Code of Australia.
For the D&BP Scheme, building element means any of the following:
Fire safety systems
Waterproofing
Building structure
Building enclosure
Building services
These are considered important as they are likely to have a greater impact on the safety and quality of construction in a building. Other types of work such as interior design, surveying, painting or landscaping, are generally not covered in this scheme.
It is imperative for all project managers to ensure that their design team is registered so that any alterations or amendments to regulated designs can be certified with a Design Compliance Declaration (DCD).
Regulated designs, compliance declarations and associated documents must be lodged in the NSW Planning Portal at the following stages:
Before building work commences
After building work commences (i.e. variations)
Before applying for an occupation certificate (OC)
After the occupation certificate has been issued
These changes form part of the NSW Government’s response to the Shergold Weir Building Confidence Report that committed to strengthening compliance in the building sector. Find more information about new obligations – designs and declarations and declaration and lodgement processes.
