Planning & Overlays

Methodology

The Planning & Overlays module resolves the subject property against the relevant planning scheme and returns the zone, permissible uses, design controls (height, FSR, minimum lot) and every overlay that intersects the parcel polygon — heritage, flood, bushfire, vegetation, design & development, environmental significance.

Each overlay is returned with a normalised "valuation impact" weighting so the report writer can foreground material constraints (e.g. heritage, flood) and the methods can adjust comparable selection automatically. State-specific schemes (VPP for Victoria, EPI for NSW, etc.) are abstracted behind a single API.

When to use it

• Always, as part of the subject-property pack.
• Critical input to the Hypothetical Development feasibility.
• Refines comparable selection in Direct Comparison (e.g. exclude HO comps).

Standards & references

• State planning legislation (P&E Act 1987 VIC, EP&A Act 1979 NSW, etc.).
• API ANZVTIP 1 — site identification and regulatory constraints.
• IVS 102 — Investigations & Compliance.

Plugin interface

Every method is a self-contained module that plugs into the Valuation App. It exposes a typed input/output schema so it can be invoked from a report writer, a workflow, or your own backend.
