Accessibility Requirements for Changes in Level

The 2010 ADA Standards and ICC A117.1 - Accessible and Usable Buildings and Facilities contain similar requirements regarding changes in level within an accessible route.  When thresholds are provided in a door opening, the maximum allowable threshold height is 1/2 inch, with the exception of existing or altered thresholds which are permitted to be 3/4-inch maximum in height (refer to the standards for additional criteria).*  These limitations on threshold height apply to manually-operated doors and automatic doors.

Reader Photos

Danny Estryk of Entry Systems Ltd. sent me these photos of some very early offset pivots.  The wood doors and the other portion of the pivots that were attached to them are long gone, but the stone portion remains.  This opening is at the Belvoir Fortress in the Jordan Valley of Israel, built by the crusaders beginning in 1168.
