This guide covers the federal law of disability access from definitions through remedies, organized by the title that applies rather than by the type of disability. Part one covers coverage and definitions after the 2008 amendments. Part two covers Title III, the obligations of private businesses open to the public, including barrier removal, policy modification, auxiliary aids, and the separate rules for new construction and alterations. Part three covers Title II and the obligations of state and local government, including program access and the integration mandate. Part four covers Section 504 and its damages remedy. Part five covers Title I employment accommodation and the interactive process. Part six covers service animals, effective communication, and website accessibility. Part seven covers procedure: standing, exhaustion, deadlines, sovereign immunity, and the four enforcement routes. Part eight covers remedies and fee awards, and part nine supplies compliance and litigation checklists for both sides.
