Design Compliance Declaration Requirements NSW
Understanding Design Compliance Declarations Under the DBP Act
One of the key requirements introduced under the Design and Building Practitioners Act 2020 (DBP Act) is the mandatory use of Design Compliance Declarations for regulated designs.
These declarations form a central part of the NSW building compliance framework and are required for many Class 2, 3 and 9c building projects.
For builders, developers, architects and consultants, understanding when declarations are required and how they are managed is essential for maintaining compliance.
What Is a Design Compliance Declaration?
A Design Compliance Declaration is a declaration issued by a registered Design Practitioner confirming that a regulated design complies with:
the Building Code of Australia,
applicable Australian Standards,
and other relevant legislative requirements.
The declaration applies to regulated designs prepared for regulated building work under the NSW DBP legislation.
Why Are Design Compliance Declarations Required?
The declarations were introduced to improve:
accountability,
documentation quality,
consultant coordination,
and construction compliance.
The NSW Government introduced the system in response to widespread building defects affecting residential apartment buildings.
The declaration framework aims to ensure that regulated designs are properly coordinated and reviewed prior to construction.
Which Projects Require Design Compliance Declarations?
Declarations generally apply to:
Class 2 buildings,
buildings containing a Class 2 component,
Class 3 buildings,
and Class 9c buildings.
This commonly includes:
apartment buildings,
mixed-use developments,
seniors living projects,
boarding houses,
aged care facilities,
and certain remedial works.
What Types of Designs Require Declarations?
Examples commonly include:
waterproofing systems,
facade systems,
fire safety systems,
structural elements,
architectural regulated designs,
and performance solutions.
The exact requirements depend on the project scope and classification.
Who Can Issue a Design Compliance Declaration?
Declarations must generally be issued by a registered Design Practitioner with the appropriate registration class relevant to the design being declared.
Depending on the project, this may include:
architects,
engineers,
facade consultants,
waterproofing consultants,
and specialist practitioners.
When Must Declarations Be Lodged?
Design Compliance Declarations must generally be lodged on the NSW Planning Portal before the relevant building work commences.
Updated declarations may also be required where regulated designs change during construction.
Design Variations and Updated Declarations
Construction-stage variations commonly trigger updated declaration requirements.
Examples include:
revised waterproofing systems,
structural changes,
facade revisions,
and modified performance solutions.
Where regulated designs are amended, updated declarations and Planning Portal submissions may also be required.
Common Design Compliance Declaration Issues
Common compliance problems include:
incomplete declarations,
inconsistent consultant documentation,
late lodgements,
undocumented design changes,
and poor revision management.
Proper coordination between consultants and contractors is essential for maintaining compliance.
Role of a Principal Design Practitioner
A Principal Design Practitioner may assist with:
coordinating declarations,
managing consultant documentation,
tracking variations,
and coordinating NSW Planning Portal lodgements.
This is particularly beneficial on large or complex Class 2 projects.
