Ontario Building Code Practice Exam

The minimum number of accessible parking spaces required for a commercial building with 200 parking spaces is 2. This is because the Americans with Disabilities Act (ADA) requires a minimum of one accessible parking space for every 25 parking spaces, with the use of "fractional" rounding (meaning 0.5 spaces or more are rounded up to the nearest whole number). In the case of a commercial building with 200 parking spaces, 200 divided by 25 is 8, and 8 divided by 2 (rounding up) is 4, but the ADA sets a maximum of 2 accessible spaces for 76-100 spaces. Therefore, the minimum number of accessible parking spaces required for a commercial building with 200 parking spaces is 2. The other options, 1, 3, and 4, do not align with the ADA requirements and would not be considered the minimum number of accessible parking spaces required.
