ADA Accessibility Checker GPT
Research door clearances, restroom layouts, ramps, parking, and accessible routes under the 2010 ADA Standards.
Conversational ADA reference for architects, interior designers, and facility managers. It helps locate scoping and technical criteria for accessible routes, doors, restrooms, parking, reach ranges, elevators, and counters; project compliance still requires the complete applicable standards and facts.
The Problem
Accessibility review requires both scoping and technical criteria. Door approach, turning space, parking, alterations, and exceptions can change which provision applies, while state and building-code requirements remain separate authorities.
How It Works
Describe the element, facility context, and whether the work is new construction or an alteration. The assistant identifies potentially relevant ADA provisions and dimensions for you to verify against the complete standard and project conditions.

Who It's For
Architects, interior designers, and CASp consultants checking specific ADA dimensions during design development or responding to plan check corrections.
This tool covers 2010 ADA Standards for Accessible Design. State-specific requirements (California CBC Chapter 11B, NYC Local Law 58) may be more restrictive — always verify with the jurisdiction. Does not replace a CASp (Certified Access Specialist) inspection for existing buildings.
Frequently Asked Questions
What is the minimum door clear width under ADA?
ADA requires 32 inches minimum clear width when the door is open 90 degrees (measured from the face of the door to the stop). A standard 36-inch door provides this clearance. The clear opening must be maintained free of obstructions — door stops, closers, and hardware must not reduce the clear width below 32 inches.
How many accessible parking spaces are required?
Per ADA Table 208.2: 1 space per 1-25 total; 2 per 26-50; 3 per 51-75; 4 per 76-100; 5 per 101-150; 6 per 151-200; then 1 per 25 above 200 up to 1000. At least 1 in 6 accessible spaces must be van-accessible. Van spaces require 8 ft minimum access aisle (or 11 ft wide space with 5 ft aisle).
What turning space is required in an accessible restroom?
ADA requires either a 60-inch diameter clear floor space (circle) or a 60-inch by 60-inch T-shaped turn space. The turning space cannot overlap with the required maneuvering clearances at the door. In single-occupancy restrooms, the turning space is typically located in the center of the room — verify the toilet clearance (18 inches min side, 60 inches front) does not conflict.
