Is a CDC cheaper than a DA + CC in NSW?

Generally yes. A CDC combines planning and building approval into a single process, eliminating separate council DA fees. The total cost and timeline are typically less than pursuing separate DA and CC pathways.

Can I negotiate certification fees in NSW?

Yes, particularly for larger projects or ongoing work. Many certifiers will negotiate on price for builders who provide regular work. Get multiple quotes to understand the market rate for your project type.

How Much Does a Building Certifier Cost in NSW?

Typical NSW certification costs

Building certification costs in NSW vary based on project type and complexity. A standard residential dwelling (Class 1a) typically costs $2,000 to $5,000 for the full certification package: plan assessment, construction certificate, mandatory inspections, and occupation certificate.

A Complying Development Certificate (CDC) for a straightforward residential project typically costs $2,000 to $5,000 for the combined planning and building approval, which is often cheaper than the separate DA and CC pathway through council.

Commercial and multi-residential costs

Multi-residential projects (Class 2 apartments) range from $10,000 to $30,000 or more depending on the number of units and complexity. Commercial fitouts (Class 5-6) typically cost $3,000 to $10,000. Major commercial developments can cost $30,000 to $100,000+ for full certification.

These higher costs reflect the greater complexity of NCC requirements for Class 2-9 buildings, including fire safety engineering, accessibility compliance, and mechanical services assessments.

What affects the price

The main cost drivers are building class (residential is simpler than commercial), number of storeys, total floor area, site constraints (bushfire zones, flood-prone land, reactive soils), the number of inspections required, and whether specialist reports are needed (fire engineering, acoustic, BAL assessments).

Some certifiers charge a flat fee for the entire project, while others charge per stage or per inspection. Make sure you understand what is included before committing, and ask what triggers additional fees.

Getting the best value

Get quotes from at least two or three certifiers. Compare what is included in each quote, not just the headline number. A certifier who includes more inspections in their base fee may be cheaper overall than one with a lower initial quote who charges per inspection.

Early engagement during the design phase can save money by identifying compliance issues before they become expensive to fix. Builders who provide regular work to a certifier often receive preferential rates.
