1107.7.1
Structures without elevator service. Where
no elevator service is provided in a structure, only the
dwelling and sleeping units that are located on stories
indicated in Sections 1107.7.1.1 and 1107.7.1.2 are required
to be Type A and Type B units. The number of Type A units
shall be determined in accordance with Section 1107.6.2.1.1.
1107.7.1.1 One story with Type B units
required. At least one story
containing dwelling units or sleeping units intended to
be occupied as a residence shall be provided with an accessible
entrance from the exterior of the structure and all units
intended to be occupied as a residence on that story shall
be Type B units.
11 07.7.1.2 Additional stories with Type
B units. On all other stories
that have a building entrance in proximity to arrival
points intended to serve units on that story, as indicated
in Items 1 and 2, all dwelling units and sleeping units
intended to be occupied as a residence served by that
entrance on that story shall be Type B units.
1.
Where the slopes of the undisturbed site measured between
the planned entrance and all vehicular or pedestrian
arrival points within 50 feet (15 240 mm) of the planned
entrance are 10 percent or less, and
2.
Where the slopes of the planned finished grade measured
between the entrance and all vehicular or pedestrian
arrival points within 50 feet (15 240 mm) of the planned
entrance are 10 percent or less.
Where
no such arrival points are within 50 feet (15 240 mm)
of the entrance, the closest arrival point shall be
used unless that arrival point serves the story required
by Section 1107.7.1.1.
1107.7.2
Multistory units. A multistory
dwelling or sleeping unit which is not provided with elevator
service is not required to be a Type B unit. Where a multistory
unit is provided with external elevator service to only
one floor, the floor provided with elevator service shall
be the primary entry to the unit, shall comply with the
requirements for a Type B unit and a toilet facility shall
be provided on that floor.
1107.7.3
Elevator service to the lowest story with units.
Where elevator service in the building provides an accessible
route only to the lowest story containing dwelling or sleeping
units intended to be occupied as a residence, only the units
on that story which are intended to be occupied as a residence
are required to be Type B units.
1107.7.4
Site impracticality. On a site
with multiple nonelevator buildings, the number of units
required by Section 1107.7.1 to be Type B units is permitted
to be reduced to a percentage which is equal to the percentage
of the entire site having grades, prior to development,
which are less than 10 percent, provided that all of the
following conditions are met:
1.
Not less than 20 percent of the units required by Section
1107.7.1 on the site are Type B units;
2. Units required by Section
1107.7.1, where the slope between the building entrance
serving the units on that story and a pedestrian or vehicular
arrival point is no greater than 8.33 percent, are Type
B units;
3.
Units required by Section 1107.7.1, where an elevated
walkway is planned between a building entrance serving
the units on that story and a pedestrian or vehicular
arrival point and the slope between them is 10 percent
or less are Type B units; and
4. Units served by an elevator
in accordance with Section 1107.7.3 are Type B units.
1107.7.5
Design flood elevation. The required
number of Type A and Type B units shall not apply to a site
where the required elevation of the lowest floor or the
lowest horizontal structural building members of nonelevator
buildings are at or above the design flood elevation resulting
in:
1.
A difference in elevation between the minimum required
floor elevation at the primary entrances and vehicular
and pedestrian arrival points within 50 feet (15240 mm)
exceeding 30 inches (762 mm); and
2.
A slope exceeding 10 percent between the minimum required
floor elevation at the primary entrances and vehicular
and pedestrian arrival points within 50 feet (15240 mm).
