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.

International Building Code 1107.7.1.1

International Building Code 1107.7.4

Site impracticality. On a site with multiple
nonelevator buildings, the number of units required by Section
1107.7.1 to be TypeBunits 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.

International Building Code 1107.7.5

Design flood elevation. The required number of

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
(15 240 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
(15 240 mm).
