Can you have unseparated uses nested within overall separated uses?

[Ryan Schultz]

Can you do something like the following? That is, having unseparated uses nested within overall separated uses?
For this example assume unsprinklered Type VB.

Yes...I'd have to spend more time looking at your particulars, but the concept is correct.

 

[RLGA]

Yes--I do this all the time. Section 508.1 specifically lists sections for each of the four methods and adds "or a combination of these sections."

2021 IBC 508.1 General​

Each portion of a building shall be individually classified in accordance with Section 302.1. Where a building contains more than one occupancy group, the building or portion thereof shall comply with the applicable provisions of Section 508.2, 508.3, 508.4 or 508.5, or a combination of these sections.
Exceptions:

1. Occupancies separated in accordance with Section 510.
2. Where required by Table 415.6.5, areas of Group H-1, H-2 and H-3 occupancies shall be located in a detached building or structure.

 

[Yankee Chronicler]

Yes.

The concept is well-established, and is referred to as "separated/non-separated."
