Buildings or portions of buildings that comply with the provisions of this section shall be considered as nonseparated occupancies.

In addition, the most restrictive provisions of Chapter 9 that apply to the nonseparated occupancies shall apply to the total nonseparated occupancy area. Where nonseparated occupancies occur in a high-rise building, the most restrictive requirements of Section 403 that apply to the nonseparated occupancies shall apply throughout the high-rise building.
No separation is required between nonseparated occupancies.
