Which connection does not require occupancy separation?

In evaluating the need for occupancy separation, it's important to understand the context of different uses and how they interact with safety codes, particularly the International Building Code (IBC).

The connection between the Proposed Gallery and the Church does not require occupancy separation. This is primarily because both spaces are likely considered under the same occupancy classification, especially if they are designed for compatible uses. When two areas are functionally tied, such as a gallery that is part of a church complex, they can share a connection without necessitating a separation that would typically be required for areas designated for different occupancies.

In contrast, connections such as a Gallery to Parking Garage or a Parking Garage to an external exit may necessitate occupancy separation due to differing uses, safety requirements, and potential fire hazards. The Gallery to restrooms connection can have specific building code implications as well, especially concerning sanitary requirements and accessibility, which also could impose separations. Thus, the key factor for the Proposed Gallery and Church is their shared functional and occupancy nature, permitting a direct connection without the need for separation barriers that would otherwise be required for dissimilar uses.
