I have found that local authorities often differ in their enforcement of the American Disabilities Act. Check with your local Authority Having Jurisdiction to be sure.
This from ADATA.org:
"Interior doors should require no more than 5 lbs. of force to open. This does not apply to the initial force needed to overcome the weight of a motionless door. Open the door gradually; do not “jerk” it open.
Opening force for exterior doors is not specified in the ADA Standards, but exterior doors that need to be accessible should have the minimum force possible. Typical maximum opening force for exterior doors ranges from 8.5 to 10 lbs. Any door so heavy that it prevents entrance by people with disabilities may deny them access to goods and services, which is covered under the ADA. Also, state or local government codes may have specific accessibility requirements for exterior doors.
The closing, or swing speed must not be faster than five seconds. The closing or swing distance is from the open position at 90 degrees to 12 degrees from the latch. Latching speed isn’t specified, but should be fast enough to latch the door but not slam it."
