Preliminary CDC assessments in NSW
A Preliminary CDC Assessment is an initial, non-binding eligibility review that checks your proposed site zoning, boundary setbacks, building heights, floor space ratios, and NSW SEPP criteria. Undertaken during early planning before finalizing full architectural plans, it confirms whether your build qualifies for fast-tracked Complying Development or requires a local Council DA.
CertifiBuild's accredited NSW certifiers conduct the Preliminary CDC Assessment, typically requested by the property owner or their builder/architect during early project planning.
Verify your planning zone (e.g. R2, R3, RU) and confirm that your planned residential or secondary building type is permitted under NSW legislation.
Assess proposed front, rear, and side boundary distances alongside maximum building height thresholds to guarantee complying development compliance.
Calculate allowable gross floor area and landscaped area percentages against lot size requirements to avoid costly architectural redesigns.
Cross-check environmental planning policies, bushfire risk, heritage overlays, and tree preservation rules before lodging formal CDC documentation.
