As per NFPA 88 A for parking structures, under 5.2 Compartmentation..

5.2.1 Those parts of parking structures located within, immediately below, attached to, or less than 3 m (10 ft) from a building used for any other purpose shall be separated by walls, partitions, floors, or floor–ceiling assemblies having fire resistance ratings of not less than 2 hours, unless otherwise permitted by 5.2.2.


Does the above mean that if I have any room other than the incidental rooms for the parking (offices that serve the parking, storage for the parking, utilities that serve the parking)....

then these rooms (other than the incidental ones)  need to be separated by 2 hr fire barrier like:

(Utility or MEP room that serve the main building (ex.assembly or business occupancy), bulk storage rooms for the tents, BOH offices, kitchens, laundries...etc) or these spaces shall be protected as per the hazardous level for each?
