ADAAG Manual

Scoping [4.1.3(10)]

ADAAG does not specify the number of fixtures a building must have. Instead it requires access based on the number provided on each floor so that half (50%) are accessible to people who use wheelchairs. Recommendation: where an odd number of units is provided on a floor, one should round up to the next higher whole number in determining the number that provides wheelchair access.

One Unit Per Floor

Where only one fixed unit is intended on a floor, dual access can be provided by:

• two separate units

• a combination "hi-lo" unit

• a fixed unit that is wheelchair accessible and a non-fixed unit (such as a bottled-water unit)

Recommendation: While other methods may be possible, fixed units are recommended over free-standing units because they require less maintenance and are more reliable from a compliance standpoint. Cup dispensers at fixed units are not recommended but if provided for dual access, the drinking fountain should be wheelchair accessible.

Exterior Sites

Recommendation: The 50% scoping required for building interiors should be followed for exterior sites. Where only one unit is provided or where they are spaced at considerable distances (such as over 200 feet), consider dual access at each location.

Dispersion

Recommendation: Wheelchair accessible units and standard units should be evenly dispersed to maximize convenient availability. For example, if a floor is occupied by separate tenancies, both types of units should be dispersed to serve occupants of each tenancy. Where only portions of a floor are accessible, such as wheelchair seating in assembly areas, be sure to locate wheelchair accessible units in proximity to, and on an accessible route from, accessible seating.

Standard Units

Units at conventional heights for use by standees are considered accessible to people who may bend or stoop with difficulty. It is important that cantilevered units meet the requirements for protruding objects so they do not pose a hazard to people with vision impairments. Recessing units in alcoves, wing walls, or other means of providing a detectable leading edge at or below 27 inches are acceptable.
