ADAAG Manual

Historic Preservation [4.1.7]

ADAAG covers historic properties in the context of planned renovations to qualified historic facilities, including those subject to the National Historic Preservation Act. "Qualified historic facilities" are facilities listed in the National Register of Historic Places or facilities designated as historic under state or local law. Alterations to such facilities are required to be done in full compliance with the alteration requirements for other types of buildings. However, if following the usual requirements would threaten or destroy the historic significance of a feature of the building, alternative criteria in 4.1.7(3) may be used. These requirements address accessible routes, ramps, entrances, toilet rooms, access between floors, and displays. The decision to use these alternative requirements must be made in consultation with the appropriate advisory board designated in 4.1.7(2).
