Parking Requirement Calculator
Calculate the number of parking spaces required for a building's built-up area.
About this calculator
Municipal building bylaws typically mandate a minimum number of parking spaces tied to a building's total built-up area, and a project that doesn't meet that minimum can stall at the plan sanction stage, making it worth checking early before finalizing a design. This calculator divides your building's total built-up area by the area-per-space norm your local bylaw specifies, rounding up to a whole number of spaces since a fractional parking space isn't buildable. Enter built-up area and the area-per-space requirement from your local development control regulations, and get the minimum required space count instantly instead of looking up the ratio and dividing by hand. Because parking norms vary considerably by city, building use type (residential versus commercial) and sometimes by building size tier, confirm the exact area-per-space figure that applies to your specific project and municipality before finalizing a parking layout.
Worked example
10,000 sqft built-up, 1 space per 500 sqft
Result: Required parking spaces = 20
