Complying Development Certification Services (CDC) - Fast & Reliable
Get your residential CDC approved quickly with Multicert – accredited certifiers helping you meet NSW compliance requirements.
At Multicert, we specialise in helping homeowners, builders and architects obtain fast and compliant Complying Development Certificates (CDC) across New South Wales. Whether you’re planning a new home, extension, pool or renovation, our team ensures your application meets all requirements — without the delays of a full DA.
As Principal Certifiers (PC), we serve as appointed building surveyors who are legislatively required to undertake a number of critical-stage and various non-mandatory inspections. Throughout these inspections, we meticulously document essential details across the construction process to verify compliance with building plans and specifications, adherencing to relevant regulations. Once the project is completed, we then issue an Occupation Certificate (OC).
