Buildable Units Calculator

Enter your lot dimensions and zoning regulations to calculate maximum gross floor area, buildable units by type, required parking, and site density.

Lot Dimensions

Lot Width (ft)Lot Depth (ft)

Gross Lot Area:10,000 sq ft(0.23 acres)

Zoning Regulations

Floor Space Ratio (FSR / FAR)e.g. 2.5 = GFA can be 2.5× the lot areaMax Lot Coverage (%)% of lot that can be covered by building footprintMax StoreysHeight Limit (m)Height and max storeys — the lesser applies

Unit & Efficiency Assumptions

Building Efficiency (%)Net sellable/rentable ÷ GFA. Typical: 82–88%Parking Ratio (stalls / unit)Based on 2+ bed units. Set to 0 for no parking.Studio / 1-Bed avg size (sq ft)2+ Bed apt avg size (sq ft)Townhouse avg size (sq ft)
