⚠️ All three layers apply to every development — verify each before issuing approvals
New single-dwelling homes only. NSW Government Pattern Book designs get 10-day CDC approval. PlotDetect checks eligibility triggers and numeric standards automatically.
Common blockers: Heritage conservation area, narrow lot (<15m), steep slope (>20%), acid sulfate soil, flood zone, bushfire zone.
Small-scale additions. Decks, garages, pools, fences, carports. Certifier approval only — no council DA. Must meet all SEPP (Exempt and Complying Development Codes) 2008 standards.
Compliance requirement: Verify all provisions against the current SEPP (Exempt and Complying Development Codes) 2008 before issuing a CDC. PlotDetect is a preliminary screener only.
Properties in Heritage Conservation Areas or listed as heritage items. Additional design controls apply. Heritage statements usually required for DA.
Most common pathway. New buildings, major alterations, additions over E&C limits, commercial, multi-dwelling. Council assessment required.
For Standard DAs. Activate DA Mode in the DCP tab to annotate provisions and export a pre-populated Statement of Environmental Effects draft.
Enable DA Mode → set development type → run triage → annotate provisions → export SEE PDF. Each N/A exclusion traces to a confirmed intake answer. See the DCP tab for the full workflow.
