B use, VB construction, not sprinklered, 2 story building.
Plan review on a wood Exterior exit stairway off of the 2nd floor. Only exit off 2nd floor (but they will need an second exit because exit travel distance is too long). Landing at second floor door goes out a total of 6', turn 90 degress to go down stairway that is 30" from building. There is a window under the landing on the first floor.
This section is greek to me and I don't understand the underlined. Also section 1023.2 doesn't say anything about exterior stairways. Please help!

1027.6 Exterior exit stairway and ramp protection. Exterior
exit stairways and ramps shall be separated from the
interior of the building as required in Section 1023.2. Openings
shall be limited to those necessary for egress from normally
occupied spaces. Where a vertical plane projecting
from the edge of an exterior exit stairway or ramp and landings
is exposed by other parts of the building at an angle of
less than 180 degrees (3.14 rad), the exterior wall shall be
rated in accordance with Section 1023.7.
Exceptions:
1. Separation from the interior of the building is not
required for occupancies, other than those in Group
R-1 or R-2, in buildings that are not more than two
stories above grade plane where a level of exit discharge
serving such occupancies is the first story
above grade plane.
2. Separation from the interior of the building is not
required where the exterior exit stairway or ramp is
served by an exterior exit ramp or balcony that connects
two remote exterior exit stairways or other
approved exits with a perimeter that is not less than
50 percent open. To be considered open, the opening
shall be not less than 50 percent of the height of the
enclosing wall, with the top of the openings not less
than 7 feet (2134 mm) above the top of the balcony.
3. Separation from the open-ended corridor of the
building is not required for exterior exit stairways or
ramps, provided that Items 3.1 through 3.5 are met:
3.1. The building, including open-ended corridors,
and stairways and ramps, shall be
equipped throughout with an automatic

ramp complying with Section 1027.
3.4. The exterior walls and openings adjacent
to the exterior exit stairway or ramp comply
with Section 1023.7.
3.5. At any location in an open-ended corridor
where a change of direction exceeding 45
degrees (0.79 rad) occurs, a clear opening
of not less than 35 square feet (3.3 m2) or
an exterior stairway or ramp shall be provided.
Where clear openings are provided,
they shall be located so as to minimize the
accumulation of smoke or toxic gases
