An office building project requires 15 accessible parking spaces. How many of these must be van-accessible according to ADA requirements?
Correct Answer
A) 1 space
ADA requires 1 van-accessible space for every 6 accessible spaces. With 15 accessible spaces, a minimum of 1 van-accessible space is required (15 ÷ 6 = 2.5, rounded down to 2, but minimum is 1 for every 6).
Why This Is the Correct Answer
According to ADA requirements, 1 van-accessible space is required for every 6 accessible parking spaces. With 15 accessible spaces total, you divide 15 by 6 to get 2.5. Since you cannot have a partial space, this rounds down to 2 spaces required. However, the ADA also specifies that at least 1 van-accessible space must be provided for every 6 accessible spaces, so the minimum requirement is met with 1 space when you have 6 or fewer accessible spaces in each group of 6.
Why the Other Options Are Wrong
Option B: 2 spaces
2 spaces would be more than the minimum required. While 15 ÷ 6 = 2.5, the ADA requirement is 1 van-accessible space for every 6 accessible spaces, which means 1 space satisfies the requirement for the first 6 spaces, and 1 additional space would be needed only if there were 12 or more accessible spaces requiring a second group.
Option C: 3 spaces
3 spaces significantly exceeds the ADA minimum requirement. This would be providing 1 van-accessible space for every 5 accessible spaces (15 ÷ 3 = 5), which is more generous than required but not the minimum standard asked for in the question.
Option D: 4 spaces
4 spaces greatly exceeds the requirement, providing 1 van-accessible space for every 3.75 accessible spaces (15 ÷ 4 = 3.75). This is well above the ADA minimum standard of 1 van-accessible space per 6 accessible spaces.
Memory Technique
Remember 'Van-6': 1 VAN-accessible space for every 6 accessible spaces. Think of a van being much larger and needing more room, so you need fewer of them.
