Structured datasets sourced from NSW Government systems and legislative instruments. All data is surfaced through the pages linked below — we do not offer bulk downloads, because regulatory data changes frequently and downloaded files become stale.
DA and CDC application volumes, processing times, pathway ratios, and self-reported build costs for secondary dwellings across 102 NSW councils. Derived from the NSW Planning Portal open data API.
Fields
Cost is self-reported at lodgement. DA status is "Determined" only — the portal does not distinguish between granted and refused outcomes.
Definitions of planning terms extracted from NSW LEPs, DCPs, and SEPPs. Each definition includes the source document, clause reference, legislation type, and domain tags.

Fields
Structured numeric development standards from SEPP (Housing) 2021 and the NSW Apartment Design Guide. Covers height limits, lot sizes, floor areas, site coverage, parking rates, setbacks, and ADG design criteria — grouped by development type with clause references.

Fields
Development Control Plan provisions extracted from council DCP documents, tagged by topic (parking, setbacks, heritage, waste, landscaping), precinct, applicable zones, and development types. Deep coverage for Inner West Council; shallower for other LGAs.

Council DCP documents (PDF extraction)
Fields
Coverage depth varies by council. Inner West has ~4,600 provisions; other councils have fewer. Provisions are extracted from DCP PDFs and may not capture all amendments.
Peak flood level and depth grids from published flood studies, sampled per property. Four studies: Hawkesbury FRMSP 2025, Tweed Valley 2024, Wollongong 2024, and Redbank Creek 2025 — with design events from 50% AEP down to 1-in-5000 AEP and PMF where the study publishes them, plus modelled historical events such as March 2022.

Study publications 2024–2025
Fields
Coverage is limited to each study’s modelled extent. Values are read from the published model grids; each study applies its own filtering criteria to shallow or low-hazard cells.
NSW-wide mapped extents showing how often low-lying land near estuaries is under tidal water, modelled under the SSP3-7.0 emissions scenario at 2050 and 2100 across four inundation frequencies (1 to 182.5 days per year). Surfaced as a mapped-extent disclosure in conveyancing reports.

Estuarine tidal inundation only — does not cover open-coast or surf inundation, coastal erosion, or rainfall-driven river flooding.
Per-field documentation for the structured planning data PlotDetect serves: what each field is, the authoritative source it is read from, its licence and attribution, how current it is, and its limits.
NSW planning instruments (LEPs, DCPs, SEPPs) are amended regularly. Downloaded CSV or JSON files become stale the moment an instrument is updated. The pages above are revalidated daily so they reflect the current state of the data. If you need programmatic access for a specific use case, get in touch.
