Navigating Class 2 Regulations Under the DBP Act in NSW: How Studio Oulala Can Help

Written By charlotte vergnolle

If you're planning a renovation, alteration and addition, or a new build involving a Class 2 building in New South Wales, it's essential to understand your obligations under the Design and Building Practitioners (DBP) Act. The legislation, introduced to improve transparency and accountability in the construction industry, has significant implications for both developers and property owners.

At Studio Oulala Architect, we specialise in helping clients navigate this regulatory environment with confidence—whether you’re upgrading an existing apartment block, adding levels to a mixed-use building, or designing a new Class 2 development from scratch.

What Is a Class 2 Building?

Class 2 buildings are multi-residential buildings, typically low- to mid-rise apartments, where people live above or below each other. These structures are now subject to more stringent compliance measures under the DBP Act.

How the DBP Act Affects You

Since July 1, 2021, the DBP Act requires that certain building work on Class 2 buildings be designed and documented by registered Design Practitioners, including architects. This includes work related to:

  • Renovations of existing apartments

  • Alterations and additions (Alt & Add)

  • Structural changes and new construction

  • Internal refurbishments such as bathroom renovations or any work that affects a building element like waterproofing, fire safety systems, or load-bearing walls

All designs must be declared compliant and lodged on the NSW Planning Portal before construction begins.

How We Support You Through the Process

At Studio Oulala, we offer end-to-end architectural services that ensure your project complies with the DBP Act and progresses smoothly from concept to construction:
