17.2.2 Maneuvering Space
Space to maneuver close to cabinets, appliances, and work areas must be provided. Each feature
must have at least 30 by 48 in of clear floor space arranged for either parallel or perpendicular
approach by wheelchair. Clear floor space may extend under the counters and into knee-space areas
up to 19 in.

17.2.3 Knee Space
Adequate knee space under counter surfaces is important for people who need to sit while performing
kitchen tasks. The space should allow them to pull up under the counter for work areas, sinks, and cook
tops. Knee room should be provided beside appliances such as ranges, ovens, and dishwashers. Knee
spaces should be at least 30 in wide, 27 in high, and 19 in deep. A width of at least 36 in is preferred
because this provides additional turning space, which is especially important in small kitchens.

17.2.4 Turnaround Space
A space large enough for a person to turn around 180 degrees should be provided in the kitchen. If
the kitchen is very small, the space can be provided immediately adjacent to the kitchen.

Pivoting Turn. Sufficient space for a complete pivoting turn can be provided with a 5-ft clear
diameter floor area. This allows a full turning radius of 360 degrees. The best location for the turn-
ing space is away from appliance areas and between walls or cabinets only.

T-Turn. A T-shaped turning space allows a three-point turn to be accomplished. By making one of
the necessary kitchen knee spaces 3 ft wide or wider, one leg of the T can be accomplished within
the knee space. This arrangement can solve maneuvering problems in very small kitchens.

17.2.5 Laying It All Out
Efficient kitchens are usually designed around a work triangle. This triangle is formed by the loca-
tion of the refrigerator, sink, and range. The arrangement of the surrounding work center depends on
the available space. In general, an L-shaped kitchen provides the best access.

17.2.6 U-Shaped Work Center
Advantages to using a U-shaped work center include
• Plenty of room to maneuver a wheelchair
• Room for two cooks
• Reduced traffic flow problems
• Reduced risk of bumping into appliances

17.2.7 L-Shaped Work Center

Advantages to using an L-shape work center are
• Traffic flow does not interfere with work triangle
• Plenty of room for storage next to each workstation
• Room for two people or a wheelchair
