Guidance on the 2010 ADA Standards for Accessible Design

Guest Rooms with Mobility Features. Scoping provisions for guest rooms with mobility features are provided in section 224.2 of the 2010 Standards. Scoping requirements for alterations are included in 224.1.1. These scoping requirements in the 2010 Standards are consistent with the 1991 Standards.

One commenter expressed opposition to the new scoping provisions for altered guest rooms, which, according to the commenter, require greater numbers of accessible guest rooms with mobility features.

Section 224.1.1 of the 2010 Standards provides scoping requirements for alterations to guest rooms in existing facilities. Section 224.1.1 modifies the scoping requirements for new construction in section 224 by limiting the application of section 224 requirements only to those guest rooms being altered or added until the number of such accessible guest rooms complies with the minimum number required for new construction in section 224.2 of the 2010 Standards. The minimum required number of accessible guest rooms is based on the total number of guest rooms altered or added instead of the total number of guest rooms provided. These requirements are consistent with the requirements in the 1991 Standards. Language in the 2010 Standards clarifies the provision of section 104.2 of the 2010 Standards which requires rounding up values to the next whole number for calculations of percentages in scoping.
