What Is a DBP Regulated Building?

In New South Wales, the introduction of the Design and Building Practitioners (DBP) Act has reshaped how certain buildings are designed, built, and maintained. The DBP legislation establishes stricter oversight for a particular class of buildings, known as “DBP regulated buildings.” But what exactly does this classification mean, and who needs to be aware of its requirements? Below, we’ll break down what DBP regulated buildings are and explain their relevance to architects, construction project managers, and apartment owners considering renovations.

What Are DBP Regulated Buildings?

DBP regulated buildings, as defined by the NSW government, refer primarily to Class 2 buildings. These buildings are typically multi-storey residential apartments or mixed-use buildings that contain a residential component. Under the DBP Act, any work involving these types of buildings requires registered practitioners to certify that the design and construction comply with safety and quality standards outlined by the Building Code of Australia (BCA).

The purpose of this regulation is to improve accountability, ensure safety, and reduce defects in medium- to high-density residential buildings. Compliance with DBP legislation is mandatory for new builds, as well as significant renovations or alterations to existing buildings.

1. What DBP Regulated Buildings Mean for Architects

For architects, DBP regulated buildings present both challenges and opportunities. Under the DBP Act, architects who work on Class 2 buildings must be registered practitioners. They are required to submit a Design Compliance Declaration (DCD), which ensures that their designs meet all relevant codes and standards before construction begins.

The DBP Act increases accountability, as architects must certify that their work is compliant with structural, fire safety, and waterproofing standards. This means architects must stay informed about evolving regulations, particularly in areas like fire safety engineering, acoustics, and sustainability.

DBP compliance also encourages more collaboration between architects and builders during the early stages of a project. By working closely with DBP-registered builders like Acrow Constructions, architects can ensure their designs are practically achievable, reducing the risk of non-compliance during construction and saving time and costs in the long run.

For architects, the key takeaway is that DBP regulated buildings demand a higher level of scrutiny, which may involve more documentation, certifications, and careful consideration of compliance during the design phase.

2. DBP Compliance for Construction Project Managers

For construction project managers, overseeing DBP regulated buildings involves new levels of responsibility and vigilance. Project managers must ensure that all trades and subcontractors working on the project are aware of and adhere to the compliance requirements laid out in the DBP Act.

The construction phase of a DBP regulated building requires stringent record-keeping and coordination to ensure that all aspects of the build meet DBP standards. Project managers are responsible for ensuring that all building practitioners on site are appropriately registered and that compliance declarations are completed and submitted at key stages.

Project managers will also need to ensure regular inspections and quality checks throughout the construction process. Any changes or modifications to the original design must be reviewed and certified by a registered practitioner, and all work must be documented in case of an audit or review by regulatory authorities.

By ensuring DBP compliance, construction project managers can mitigate the risk of costly defects, protect their clients from liability, and ensure the building meets all required safety and quality benchmarks.

3. What Apartment Owners Need to Know About Renovations

For apartment owners in Class 2 buildings, understanding DBP regulations is crucial when planning renovations. Any significant renovations to common property or individual apartments—especially structural changes or upgrades to fire safety and waterproofing systems—fall under the DBP Act if they affect the integrity of the building.

Renovations in DBP regulated buildings require the involvement of registered design and building practitioners to ensure the work meets the necessary safety standards. This means that apartment owners must engage licensed professionals who can provide the required compliance declarations, even for renovations that seem straightforward.

Engaging a DBP-registered builder like Acrow Constructions for your renovation is essential. The builder will ensure that the renovation meets all compliance requirements, avoiding future legal or safety issues. For apartment owners, DBP compliance is a safeguard that ensures the quality and longevity of their investment, offering peace of mind that renovations are being carried out according to the highest standards.


DBP regulated buildings represent an important step forward for safety, quality, and accountability in NSW’s residential construction industry. Whether you’re an architect designing a new multi-residential project, a construction project manager ensuring the smooth delivery of a complex build, or an apartment owner planning renovations, understanding DBP compliance is critical to your success.

By working with registered and experienced DBP practitioners, you can ensure that your project not only meets legal requirements but also benefits from the increased safety, structural integrity, and accountability that come with DBP compliance. At Acrow Constructions, we’re committed to helping our clients navigate these requirements and delivering projects that stand the test of time.
