36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

Comment. Commenters suggested that the definition for "mezzanine" should be revised for consistency with model building codes, including the IBC.

Response. "Mezzanine" is now defined by the same definition used in the IBC: "An intermediate level or levels between the floor and ceiling of any story with an aggregate floor area of not more than one-third of the area of the room or space in which the level or levels are located." The Board has included clarification that mezzanines are elevated high enough to accommodate human occupancy on the floor below.
