I am working on a 4-story multifamily building that's above a 1-level parking garage on the ground floor.
The exterior wall is less than 10-ft fire separation distance to the property line, requiring the exterior wall it to be 1-hour fire-resistance-rated.
Since it is an open parking garage, I need a lot of openings within this wall to provide ventilation. Denver has an amendment that allows 50% allowable openings with water curtains per NFPA 13.
Since the parking garage will have a dry system, is this even possible?
It seems like a very odd condition but again I need over 25% opening within the wall to comply as an open parking garage.
