Section 100.205(c)(3)(i) provides that all covered multifamily dwellings with a building entrance on an accessible route shall be designed and constructed in such a manner that all premises within covered multifamily dwelling units contain an accessible route into and through the covered dwelling unit.
Guideline
Accessible routes into and through dwelling units would meet section
100.205(c)(3)(i) if:
-
A minimum clear width of 36 inches is provided.
In single-story dwelling units, changes in level within the dwelling unit with heights between 1/4 inch and 1/2 inch are beveled with a slope no greater than 1:2. Except for design features, such as a loft or an area on a different level within a room (e.g., a sunken living room), changes in level greater than 1/2 inch are ramped or have other means of access. Where a single story dwelling unit has special design features, all portions of the single-story unit, except the loft or the sunken or raised area, are on an accessible route; and
-
In single-story dwelling units with lofts, all spaces other than the loft are on an accessible route.
Design features such as sunken or raised functional areas do not interrupt the accessible route through the remainder of the dwelling unit.
In multistory dwelling units in buildings with elevators, the story of the unit that is served by the building elevator (a) is the primary entry to the unit; (b) complies with Requirements 2 through 7 with respect to the rooms located on the entry/accessible floor; and (c) contains a bathroom or powder room which complies with Requirement 7. (Note: multistory dwelling units in non-elevator buildings are not covered dwelling units because, in such cases, there is no ground floor unit.)
Except as noted in paragraphs (5) and (6) below, thresholds at exterior doors, including sliding door tracks, are no higher than 3/4 inch. Thresholds and changes in level at these locations are beveled with a slope no greater than 1:2.
Exterior deck, patio, or balcony surfaces are no more than 1/2 inch below the floor level of the interior of the dwelling unit, unless they are constructed of impervious material such as concrete, brick or flagstone. In such case, the surface is no more than 4 inches below the floor level of the interior of the dwelling unit, or lower if required by local building code.
At the primary entry door to dwelling units with direct exterior access, outside landing surfaces constructed of impervious materials such as concrete, brick or flagstone, are no more than 1/2 inch below the floor level of the interior of the dwelling unit. The finished surface of this area that is located immediately outside the entry may be sloped, up to 1/8 inch per foot (12 inches), for drainage.
Requirement 5. Light switches, electrical outlets, thermostats and other environmental controls in accessible locations.
Section 100.205(c)(3)(ii) requires that all covered multifamily
dwellings with a building entrance on an accessible route shall be designed
and constructed in such a manner that all premises within covered multifamily
dwelling units contain light switches, electrical outlets, thermostats, and
other environmental controls in accessible locations.
Guideline
Light switches, electrical outlets, thermostats and other environmental
controls would meet section 100.205(c)(3)(ii) if operable parts of the
controls are located no higher than 48 inches, and no lower than 15 inches,
above the floor. If the reach is over an obstruction (for example, an
overhanging shelf) between 20 and 25 inches in depth, the maximum height is
reduced to 44 inches for forward approach; or 46 inches for side approach,
provided the obstruction (for example, a kitchen base cabinet) is no more than 24 inches in depth. Obstructions should not extend more than 25 inches from
the wall beneath a control. (See Fig.2.)
Note
Controls or outlets that do not satisfy these specifications are
acceptable provided that comparable controls or outlets (i.e., that perform
the same functions) are provided within the same area and are accessible, in
accordance with this guideline for Requirement 5.
Requirement 6. Reinforced walls for grab bars.
Section 100.205(c)(3)(iii) requires that covered multifamily dwellings
with a building entrance on an accessible route shall be designed and
constructed in such a manner that all premises within covered multifamily
dwelling units contain reinforcements in bathroom walls to allow later
installation of grab bars around toilet, tub, shower stall and shower seat,
where such facilities are provided.
Guideline
Reinforced bathroom walls to allow later installation of grab bars
around the toilet, tub, shower stall and shower seat, where such facilities
are provided, would meet section 100.205(c)(3)(iii) if reinforced areas are
provided at least at those points where grab bars will be mounted. (For
example, see Figs. 3, 4 and 5.) Where the toilet is not placed adjacent to a
side wall, the bathroom would comply if provision was made for installation of floor mounted, foldaway or similar alternative grab bars. Where the powder
room (a room with a toilet and sink) is the only toilet facility located on an accessible level of a multistory dwelling unit, it must comply with the
requirement for reinforced walls for grab bars.
Note
Installation of bathtubs is not limited by the illustrative figures; a
tub may have shelves or benches at either end; or a tub may be installed
without surrounding walls, if there is provision for alternative mounting of
grab bars. For example, a sunken tub placed away from walls could have
reinforced areas for installation of floor-mounted grab bars. The same
principle applies to shower stalls -- e.g., glass-walled stalls could be
planned to allow floor-mounted grab bars to be installed later.
Reinforcement for grab bars may be provided in a variety of ways (for
example, by plywood or wood blocking) so long as the necessary reinforcement
is placed so as to permit later installation of appropriate grab bars.
