Are there any State or Federal agencies that proactively enforce the ADA?

While multiple Federal agencies are tasked with enforcing parts of the Americans with Disabilities Act (ADA), they rely on individuals to file complaints to start the process. The ADA is a complaint-driven law. Title I (employment provisions of the ADA) are covered by the Equal Employment Opportunity Commission. The Department of Justice enforces Title II (state and local government) and Title III (places of public accommodation). Other federal agencies with enforcement responsibilities include the Department of Transportation and the Federal Communications Commission. At a State level you will find agencies such as NY State Division of Human Rights or the NJ Division on Civil Rights that enforce state nondiscrimination laws.
