This image shows a door with a deadbolt and a thumbturn. There are a lot of manufacturers that make these types of locks, but the lever must be easily rotated with a loose grip or closed fist. A smaller lever may require tight grasping, pinching or twisting of the wrist, which is not allowed. Most manufacturers will list if their product complies with ADA standards. This is not always true but without that certification you should at least continue looking elsewhere.

ADA Requirements:

ADA requires that door and gate hardware including handles, pulls, latches, locks and other operable parts comply with Operable Parts. (309.4 and 404.2.7).

309.4 Operation. Operable parts shall be operable with one hand and shall not require tight grasping, pinching, or twisting of the wrist. The force required to activate operable parts shall be 5 pounds (22.2 N) maximum.

404.2.7 Door and Gate Hardware. Handles, pulls, latches, locks, and other operable parts on doors and gates shall comply with 309.4…

Also, the height of the door hardware shall be installed between 34” and 48” above the finish floor, (404.2.7). I usually see this done correctly but occasional it will be placed outside of this range.

404.2.7 Door and Gate Hardware. …Operable parts of such hardware shall be 34 inches (865 mm) minimum and 48 inches (1220 mm) maximum above the finish floor or ground…
