This guide presents an informal overview of some basic Americans with Disabilities Act (ADA) requirements for small businesses that provide goods or services to the public. References to key sections of the regulations or other information are included. The first section describes the ADA briefly. Section two lists the 12 categories of public accommodations or types of private businesses for which the ADA has established requirements, including stores and shops, restaurants and bars, service establishments, theaters, hotels, recreation facilities, private museums and schools and others. The third section focuses on existing facilities, covering these topics: architectural barriers, removal of architectural barriers, priorities for barrier removal, and examples of barrier removal such as accessible parking, accessible entrance, doors at entrances to businesses, turnstiles and security gates at entrances, shelves and maneuvering space, sales and service counters, serving counters, and fixed seating and tables. The next section makes suggestions for reviewing business policies and procedures. Next, communicating with customers with hearing or speech disabilities is addressed. The sixth section provides information on tax credits and deductions to help defer costs of compliance. New construction and alterations are discussed in the seventh section. The last section lists ADA information sources. (YLB)
