Guide to the ADA Standards

Are exit doors usable only in one direction required to comply on both sides?

Under the ADA Standards, compliance is not required on both sides of those doors or gates that can be used in one direction only, such as exit-only doors. Compliance is required only on the usable side. However, if a door or gate is usable in both directions, even occasionally, such as exit-only doors that may automatically unlock in emergencies to be usable from both directions, then compliance on both sides is required.
