State And Local Government Compliance: 

For new construction and alterations State and Local Government must follow either of two accessibility standards. It can choose either the Uniform Federal Accessibility Standards or the Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities, which is the standard that must be used for public accommodations and commercial facilities under title III of the ADA. If the State or local government chooses the ADA Accessibility Guidelines, it is not entitled to the elevator exemption (which permits certain private buildings under three stories or under 3,000 square feet per floor to be constructed without an elevator).
