As of 2015, Title I of the Americans with Disabilities Act applies to small businesses with 15 or more employees, according to the Equal Employment Opportunity Commission. Title III of the ADA applies to businesses of any size that provide public accommodations, notes the U.S. Department of Justice.
Title I of the ADA requires employers to provide reasonable accommodation to employees with qualified disabilities, states the EEOC. A person has a qualified disability if he has the requisite skills or education for the position and can perform the job with or without reasonable accommodation. A reasonable accommodation is a modification to the job that does not require significant difficulty or expense to the employer.
Title III of the ADA requires public accommodations to provide equal access, including furnishing auxiliary aids and removing architectural barriers, to individuals with disabilities, states the Department of Justice. Public accommodations include restaurants, retail stores, libraries, health spas and day care centers.
