Zoning & Site Planning Tools

Before an architect draws a floor plan, the zoning map has usually decided how much building the lot can hold. FAR Calculator turns that rule into numbers: list each floor type with its area and count, untick the spaces your code leaves out, and it returns the gross floor area, the floor area ratio and what is left of the allowance, down to how many more typical floors would fit.

Lot coverage, setbacks, height limits and urban density come next, followed by excavation and backfill volumes for the site itself.
