Exist discharge under building/stairs

[tws2106]

We received a comment from a city reviewer regarding our exit discharge not being able to travel underneath the building. The discharge path does not travel back into the building but travels under the 2 floor. Essentially think of the 2nd floor as forming a bridge and the discharge goes under it. They referenced 1028.4 Egress courts, and stated that it had to be open to the sky. However I'm not able to find the "open to the sky" verbage in the Code. Has anyone come across this type of situation before?

The building is a 9 unit (R-2), 3 story type VB construction with sprinklers.

See the definitions of court and yard which are used in the definition of egress court.

You could possible make it an exit passageway if there are no openings in the "court".

Plus , without a drawing,,,

You may still be in the building!!!

Horizontal projection

 

[cda]

The definition of building area is the area included within the surrounding exterior walls of the building, and the definition further
states that the floor area of a building or portion thereof not provided with surrounding exterior walls shall be the usable area under the horizontal projection of the roof or floor above. The intent of this latter provision is to address where a structure may not have exterior walls or may have one or more sides open without an enclosing exterior wall. Examples would include a canopy covering pump islands at a service station, or the drive-through area of a fast food restaurant. Where a column line establishes the outer perimeter of the usable space under the
202-3. If all of the area beneath the roof above can be considered usable 16 space, then the building area is measured to the leading edge of the roof
Projection
roof, it is also typically the extent of building area. Beyond the column line, the overhead cover is simply viewed as a projection. See Figure
above.

We just discussed a similar situation last week:

Elevated Buildings in flood zone and exit access and exit discharge

First post - wanted to make a good one. I am trying to interpret a few things mainly including "Building" and "exit discharge". Quick code items = type II-B, full concrete construction, fully sprinklered, Business occupancy, 462 total occupants, 24,217 total SF (1st & 2nd floors), V-22 flood...
