Clearance in kitchens

For kitchens built in a U-shape, or three enclosed walls (figures a and b), there must be a minimum of 60 inches (1525 mm) clearance. Kitchens that allow a pass through, with counters and appliances on opposing sides, there must be a minimum of 40 inches (1015 mm) of clearance.

Clear space in bathrooms and tub areas

 

In bathrooms where a tub is present, clear floor space is required. For a tub with a seat installed (a, left) with a parallel approach, there is a 30 inch (760 mm) minimum width by 60 inch (1525 mm) minimum length clear space requirement alongside the tub. If the approach is perpendicular to the tub (a, right), the requirement changes to a space with a 48 inch (1220 mm) minimum width by 60 inch (1525 mm) minimum length. 

When the seat is installed at the head of the tub (b), if the approach is parallel, there is a required minimum 30 inch (760 mm) width by 75 inch (1905 mm) clear space. Also, the seat must be at least 15 inches (380 mm) wide and extend the full width of the tub. 

 Grab bars in tubs

When the seat is installed in the tub (a), a grab bar must be at least 24 inches (610 mm) in length, measured from the outer edge of the tub. In addition, two grab bars are required on the back wall. These bars must be at least a minimum of 24 inches (610 mm) in length and should be located a maximum of 12 inches (306 mm) from the foot of the tub and 24 inches (610 mm) from the head of the tub. The first bar should be located 9 inches (230 mm) above the tub's rim, which the second should be between 33 to 36 inches (840 mm to 910 mm) above the bathroom floor.

If the seat is installed at the head of the tub, grab bar measurements are slightly different. At the foot of the tub, a garb bar should be minimum 24 inches (610 mm) in length. In addition, two grab bars are required to be installed on the back wall. These bars must be a minimum of 48 inches (1220 mm) in length and should be located a maximum of 12 inches (305 mm) from the foot of the tub and a maximum of 15 inches (380 mm).

Clear space in water closets

Depending on the angle of transfer to the water closet, the required minimum of clear floor space varies. For a front transfer, ensure an area at least 48 inches (1220 mm) in width by 66 inches (1675 mm) in length - at the minimum. Diagonal transfers require a minimum 48 inches (1220 mm) wide by 56 inches (1420 mm) long area of open space. For a side transfer to the water closet, the minimum floor space required is an area of 60 inches (1525 mm) in width by 56 inches (1420 mm) in length.   

Grab bars in water closets

For grab bars located in the water closet, be sure to check the required locations and measurements to ensure full useability. For bars located along the back wall, a 36 inch (915 mm) length is required. The bar should be mounted between 33 and 36 inches (840-915 mm) from the floor. Ensure that the grab bar extends a minimum of 12 inches (305 mm) beyond the center of the water closet toward the side wall, along with a 24 inch (610 mm) minimum reach toward the open side of either a left or right side approach. 

A grab bar should also be located on the side wall.  This bar should measure 42 inch (1065 mm) in length and should be mounted at least 12 inches (305 mm) maximum from the back wall. It should extend at least 54 inches (1370 mm) from the back wall and should be mounted at least 33 to 36 inches (840-915 mm) from the floor. In addition, the toilet paper dispenser needs to be mounted at least 19 inches (485 mm) from the floor as well. 

 Clear space and clearance around doors

For a traditional swinging door, on the pull side of the door, there must be at least 18 inches (455 mm) of maneuvering space beyond the latch side of the door, in addition to 60 inches (1525 mm) of space perpendicular to the doorway. On the push side of swinging doors, there must be at least 12 inches (305 mm) of space beyond the latch of the door and at least 60 inches (1525 mm) of space perpendicular to the doorway. For front approaches to the push side of a swinging door,, equipped with both closer and latch, ensure there is a minimum of 12 inches (305 mm) of maneuvering space beyond the latch side of the door and another 48 inches (1220 mm) of space perpendicular to the doorway.

Ramp design and measurement

 

To meet UFAS requirements, the maximum slope of a new constructed ramp is 1:12 and the rise should be no more than 30 inches (760 mm). The ramp must also be at least 36 inches (915 mm) wide - this is a minimum. In addition, each ramp should have level landing at the top and bottom. If a ramp changes directions at a landing, regulations declare that the landing must be at least 60 inches by 60 inches (1525 mm by 1525 mm) in area to ensure the ability to maneuver and turn. If a ramp has a greater rise than 6 inches (250 mm), then proper handrails are required on both sides. 

 Handrail measurements and extensions

Handrails should be provided on both sides of a ramp or stairs and should extend at least 12 inches (305 mm) beyond the top and bottom segment if not continuous. These extensions need to be parallel to the floor or ground. Ensure that there is a minimum of 1-1/2 in. (38 mm) of clear space between the railing and the wall. The end of railing should be rounded, or continue smoothly into the floor. Also, railing should not rotate within it's fittings.
