How to Use This Calculator
Lot Size
Enter the gross lot area in square feet. Use the preset buttons for common acreages (¼, ½, 1, 2, 5 acres).
Max FAR
Floor Area Ratio from your zoning ordinance. Total buildable GFA = Lot Size × FAR. Find it on the zone page for your county.
Bonus FAR
Some zones allow higher FAR through incentive programs (affordable units, structured parking, green building). Enter if applicable.
Coverage %
Maximum lot coverage limits the building footprint. Setbacks further reduce usable area — account for those separately.
