Correct answer: 1:12
The ADA Standards require a maximum slope of 1:12 (one inch of rise per 12 inches of run) for accessible ramps.
Question 2: A doorway in an existing facility measures 30 inches wide. Which ADA barrier removal strategy is most appropriate?

- Widen the door to 36 inches immediately
- Post a sign directing users to an alternate accessible route
- Apply for a hardship exemption from the local building department
Correct answer: Install an offset (swing-clear) hinge to gain clear width
Offset hinges can add up to 2 inches of clear width, often bringing a 30-inch door to the 32-inch minimum without structural work.

Title III places the obligation to remove barriers in places of public accommodation on the private business owner when removal is readily achievable.
