Ontario Building Code Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

The minimum number of accessible parking spaces required for a commercial building is determined by the Ontario Building Code, which sets specific standards to ensure that facilities are accessible to all individuals, including those with disabilities.

For a parking lot with 300 spaces, the code stipulates that a certain percentage of total parking spaces must be designated as accessible. According to the regulations, one accessible parking space is required for every 100 parking spaces, plus an additional space for every 6 spaces over that count. In practical terms, this means that for 300 total parking spaces:

- The first 100 spaces require 1 accessible space.

- The next 200 spaces also require an additional 2 accessible spaces (1 for each additional 100 spaces).

Therefore, the calculation is as follows:

- For 300 spaces, you will have 3 accessible spaces for the first 300 total spaces. This is determined by taking the total and dividing by 100, which gives you 3 accessible spaces (100 spaces = 1, 200 = 2, and the remainder provides 1 more).

Thus, the requirement is 5 accessible parking spaces for commercial buildings with 300 parking spaces.

This understanding reflects the importance of ensuring that parking facilities are compliant with accessibility
