I would define "staying within one standard" to mean using NFPA 13R as the basis but using NFPA 13 for areas outside the dwelling unit. Same would be true for an NFPA 13 design where this document might refer you to another standard.

Capsule version of the material is to clarify that if a building (such as a pedestal or podium type) is divided into separate buildings as defined by the code, that 13R is applicable in the R-group building and 13 would apply to the other. This represents a change from what we've been saying (myself, AFSA, here in this thread) WRT to "mixed use" buildings requiring a 13 design unconditionally. But the proposed language makes very clear that these provisions apply to buildings that are no more than 4 stories above "grade plane" (also as defined by the code), so if we're talking about a 5-story structure (per code), the applicable standard is 13. Period.

I have an excerpt from the 2006 Building Safety Journal that may help. "In addition to the basic requirement that the pedestal building be of Type IA construction and separated from the buildings above by a horizontal ceiling/floor/roof assembly having a minimum 3-hour fire resistance rating, the following limitations also apply. * Per Section 508.2, Item 4, Exceptions, the use of the pedestal building is restricted to any combination of the following: * S-2 enclosed parking garage; * multiple Group A uses limited to those having assembly rooms with occupant loads of less than 300 each; * Group B uses; * Group M uses; and * entry lobbies, mechanical rooms, storage areas and similar uses incidental to the operation of the building. * Per Section 508.2, Item 3, the use of the buildings above the pedestal building is restricted to any combination of the following: * Group R uses, * multiple Group A uses limited to those having assembly rooms with occupant loads of less than 300 each, * Group B uses and * Group M uses.
