Cape Town Development Rights Calculator by A4AC Architects
Enter any Cape Town erf number and this free calculator tells you what you can legally build on it — permissible floor area, footprint, storeys, height, parking and indicative unit yield. It reads zoning and parcel geometry live from the City of Cape Town's own map service and applies the Development Management Scheme tables current to the 1 October 2025 amendment.
Built and maintained by A4AC Architects. No sign-up, no fee.
Disclaimer. This calculator is in beta and has not been independently audited. Output is indicative only, is not a zoning certificate, valuation, town planning opinion or quantity surveyor's estimate, and confers no right. Verify all figures with the City of Cape Town before relying on them. Prepared by A4AC Architects, Architecture for a Change (Pty) Ltd.
