The ADA requires extensive renovation of all state and local government buildings to make them accessible.
The ADA requires all government programs, not all government buildings, to be accessible. “Program accessibility” is a very flexible requirement and does not require a local government to do anything that would result in an undue financial or administrative burden. Local governments have been subject to this requirement for many years under the Rehabilitation Act of 1973. Not every building, nor each part of every building needs to be accessible. Structural modifications are required only when there is no alternative available for providing program access. Let’s say a town library has an inaccessible second floor. No elevator is needed if it provides “program accessibility” for persons using wheelchairs by having staff retrieve books.
