28 CFR Part 36, Appendix C: Guidance on ADA Regulation on Nondiscrimination on the Basis of Disability by Public Accommodations and in Commercial Facilities (2010 ADA Title III Regulations: 1991 Preamble and Section-by-Section Analysis)

Largely in response to comments, the Board made numerous changes from its proposal, including the following:

- Generally, at least 50% of public entrances to new buildings must be accessible, rather than all entrances, as would often have resulted from the proposed approach.

- Not all check-out aisles are required to be accessible.

- The final guidelines provide greater flexibility in providing access to sales counters, and no longer require a portion of every counter to be accessible.

- Scoping for TDD's or text telephones was increased. One TDD or text telephone, for speech and hearing impaired persons, must be provided at locations with 4, rather than 6, pay phones, and in hospitals and shopping malls. Use of portable (less expensive) TDD's is allowed.

- Dispersal of wheelchair seating areas in theaters will be required only where there are more than 300 seats, rather than in all cases. Seats with removable armrests (i.e., seats into which persons with mobility impairments can transfer) will also be required.

- Areas of refuge (areas with direct access to a stairway, and where people who cannot use stairs may await assistance during a emergency evacuation) will be required, as proposed, but the final provisions are based on the Uniform Building Code. Such areas are not required in alterations.

- Rather than requiring 5% of new hotel rooms to be accessible to people with mobility impairments, between 2 and 4% accessibility (depending on total number of rooms) is required. In addition, 1% of the rooms must have roll-in showers.

- The proposed rule reserved the provisions on alterations to homeless shelters. The final guidelines apply alterations requirements to homeless shelters, but the requirements are less stringent than those applied to other types of facilities.

- Parking spaces that can be used by people in vans (with lifts) will be required.

- As mandated by the ADA, the Board has established a procedure to be followed with respect to alterations to historic facilities.
