Yes. Title III of the ADA prohibits public accommodations and commercial facilities from discriminating against people with disabilities. Public accommodations are private entities that own, lease, lease to, or operate a place of public accommodation, which include nearly every type of establishment that provides goods or services to the general public, such as a real estate brokerage office, retail stores, hotels, restaurants, and so forth. This may even include a place of public accommodation located in a private residence. Commercial facilities are privately owned, nonresidential facilities such as office buildings, factories, or warehouses.
There are also ADA Standards for Accessible Design (SAD). These standards apply to new construction and alterations to public accommodations and commercial facilities. The ADA requires that a place of public accommodation remove barriers if the removal is readily achievable even when no alterations or renovations are planned. Readily achievable means easily accomplishable and able to be carried out without much difficulty or expense.
Both a tenant and owner of a place of public accommodation are subject to ADA compliance. Brokers representing parties to transactions involving places of public accommodations should recommend that their clients hire experts to conduct an ADA review.
