Building Coverage & Floor Area Ratio

Building coverage ratio (BCR) is the building footprint as a share of the site; floor area ratio (FAR) is the total above-ground floor area as a share of the site. Both are limited by local zoning when planning a building.

Note

FAR floor area usually excludes basements and some parking, and legal limits differ by jurisdiction — check local regulations.
