Brisbane City Plan 2014 Overlay & Compliance Checking
Planning & Constraints Analysis
Understand what you can and cannot build on a Brisbane property before you buy or design. Our planning constraints analysis automatically checks Brisbane City Plan 2014 overlays, heritage registers, flood data, and development application history to identify restrictions and opportunities.
Key Capabilities
What's Included
Traditional Building Character Overlay
Identifies properties within Brisbane's Traditional Building Character overlay areas. These provisions affect demolition controls, building height, form, and materials for new construction and alterations. Understanding character provisions is critical before designing any renovation or addition.
Flood Overlay & Risk Assessment
Checks Brisbane River and creek flood overlays with property-level flood depth data where available. Flood overlay status affects insurance, building requirements, minimum floor levels, and can significantly impact property value and development potential.
Heritage Overlay (Local & State)
Checks both local Brisbane City Council heritage listings and Queensland Heritage Register entries. Heritage-listed properties have strict controls on alterations, materials, and demolition that must be navigated through heritage-specific approval pathways.
Basement Compliance Testing
For properties considering basement construction, our tool tests the proposed design against City Plan 2014's basement definition. The Level 2 floor must be no more than 1.0m above natural ground level at any perimeter point — we calculate compliance at every point.
Process
How It Works
Property Location Lookup
Enter the property address to retrieve its cadastral lot and plan details, which are used to query Brisbane City Council's spatial overlay databases.
Overlay Intersection Analysis
The system checks the property boundary against all relevant City Plan 2014 overlays: character, heritage, flood, landslide, and biodiversity. Results are returned as a traffic-light summary (green/amber/red).
DA History Review
Planning Alerts API is queried for recent development applications within proximity of the property. This reveals what neighbours have built, approval trends, and potential upcoming changes to the streetscape.
Compliance Assessment
For specific build scenarios, the system assesses compliance with relevant overlay provisions and generates a summary of constraints, required approvals, and potential resolution options.
Data Sources
All data is sourced from publicly available datasets and official APIs. No proprietary or private data is used.
