Lot Coverage Calculator

Compute lot coverage ratio, floor area ratio (FAR), and open space from lot and building data.

Total Lot Area (sq ft)

Building Footprint Area (sq ft)

Number of Floors

Other Impervious Area (sq ft) - driveways, patios

Maximum Allowed Coverage (%)

Max Buildable Footprint (at allowed %)

Status

Lot Coverage & FAR

Lot Coverage = Building Footprint / Lot Area x 100%

FAR = Total Floor Area / Lot Area

Open Space = Lot Area - Footprint - Impervious
