During plan review, you notice the accessible parking spaces are located 200 feet from the building entrance, but a shorter route exists through landscaping. According to ADA requirements, what action is required?

Option A: The current layout is acceptable if properly marked

This is incorrect because proper marking alone does not address the fundamental ADA requirement that accessible parking must be on the shortest accessible route. The 200-foot route violates this principle when a shorter route exists, regardless of how well it's marked.

Option B: Accessible spaces must be relocated to the shortest route

While relocating spaces would solve the problem, it's not always the required or most practical solution. The ADA allows for creating an accessible path along the shortest route rather than mandating relocation, especially when site constraints make relocation difficult or impossible.

Option D: Additional accessible spaces must be provided at both locations

This creates unnecessary redundancy and exceeds ADA requirements. The code requires accessible spaces to be on the shortest accessible route, not that spaces be provided at multiple locations. This would also likely exceed the required number of accessible spaces.
