DA and CDC Approval in NSW – Essential Checklist

Comprehensive DA and CDC approval checklist in Sydney. Learn NSW requirements, costs, and process for council DA and complying development certificates.

In New South Wales (NSW), the building and design industry recognises two main approval pathways: the Development Application (DA) and the Complying Development Certificate (CDC). Understanding their differences, documentation requirements, and approval processes is essential for architects, building designers, and property owners to ensure compliance with local planning and construction regulations.

While a DA involves a formal submission to the local council and a detailed assessment against planning policies, land use controls, and environmental considerations, a CDC offers a faster, more streamlined approval process for straightforward projects that meet specific NSW State Environmental Planning Policy (SEPP) requirements. Selecting the right pathway can significantly impact project timelines, approval costs, and construction scheduling.

Understanding DA – Development Application Process

A Development Application is lodged with the local council for projects such as residential home builds, commercial developments, renovations, and structural modifications. This process is designed to ensure the proposed works meet zoning regulations, heritage requirements, environmental considerations, and building codes.

For a successful DA approval in NSW, applicants must prepare a complete set of documents, which often includes:

  • Architectural plans showing the entire site, landscaping details, BASIX commitments, existing structures, and proposed works, including any demolitions and easements.
  • Elevations and sections indicating natural ground levels, proposed changes, and height measurements from base to roof ridge.
  • Cut, fill, and retaining wall plans if earthworks are required.
  • Materials and finishes schedules detailing external colours, finishes, and textures.
  • BASIX certificate for projects with an estimated cost above $50,000.
  • Stormwater concept plans detailing the proposed drainage systems.
  • Survey plans outlining property boundaries and site conditions.
  • Structural engineering plans certified by a qualified engineer.
  • Additional reports or certificates for specific conditions, such as bushfire assessments, demolition approvals, waste management plans, or environmental impact statements.

The DA approval process varies by council, such as the Parramatta Council DA requirements or Central Coast regulations, and can involve public notifications, council meetings, and possible amendments to plans before approval is granted.

Complying Development Certificate – Fast-Track Building Approval

A Complying Development Certificate (CDC) is an alternative to the DA process for low-impact, straightforward projects that meet all NSW complying development standards. The approval can be issued by either a local council or a private certifier without a full DA review, significantly reducing timeframes.

Typical projects eligible for CDC approval in NSW include small extensions, internal refurbishments, and certain residential or commercial fit-outs. To obtain CDC building approval, applicants generally need to provide:

  • A recent Section 149(2) Planning Certificate.
  • Three sets of architectural plans that comply with the NSW General Housing Code, including landscaping and BASIX details.
  • A current BASIX certificate.
  • Three sets of building specifications and structural engineer’s plans.
  • A recent survey plan and stormwater plans that meet council policy.
  • Sydney Water Quickcheck approval stamp.
  • Proof of Long Service Levy payment at 0.35% of the project’s estimated cost.
  • Owner’s consent if lodging on behalf of the property owner.
  • Builder’s licence details and homeowner’s warranty insurance for works valued over $20,000, or an owner-builder’s permit if applicable.

The CDC requirements in NSW are strict but straightforward—if all criteria are met, the approval is generally issued within a matter of days. This makes it a preferred route for many builders and developers looking to save time on low-complexity projects.

Choosing Between DA and CDC – Costs, Timelines, and Compliance

The decision between DA and CDC approval depends on the project’s complexity, site conditions, and compliance with NSW building codes.

  • DA approval is suited for projects that require flexibility in design but involve more complex assessment and longer timelines. The DA approval process can take weeks to months, depending on council workloads and community feedback.
  • CDC building permits offer faster outcomes but are only available if every requirement of the NSW complying development standards is met. The cost of a CDC certificate is generally lower than that of a DA due to reduced assessment time and fewer administrative processes.

When considering costs, applicants should factor in council fees, consultant charges, and possible redesign expenses if an application is rejected. For example, the CDC approval cost can vary depending on the local council or certifier’s fees, while DA approval NSW cost depends on the project scale and location.

For residents in specific council areas—such as Parramatta Council DA applications or Central Coast DA approvals—it is advisable to review local guidelines early in the design process. Consulting a qualified complying development certifier or building designer can prevent costly delays and ensure compliance from the outset.
