The American with Disabilities Act of 1990 is a law that ensures the civil rights to the
handicapped, by preventing discrimination against those with disabilities. The ADA also formed a
set of codes and standards for structures so they have access to the surroundings as those without
disabilities would. Two years ago, the “2010 ADA Standards for Accessible Design” was published
stating what steps need to be taken to properly design a house to be handicap accessible. Accidents
occur frequently in the bathroom, and the ADA specifications make it capable of being safer in such
as dangerous place (United States Department of Justice). About 234,000 nonfatal accidents happen
in the bathroom each year by people over the age of 15. Of those 234,000, 81% of those are caused
by falls. 2/3 of the accidents happen in the bathtub/shower, and although only 1% of nonfatal
injuries happen in the bathroom, that percentage increases to 2.5% for those 65 and older
The objective of this project is to design an Accessible Entrance, Kitchen, and Bathroom
with a total available space of approximately 16 feet by 24 feet; the space should meet or exceed the
specifications as in the 2010 ADA Standards. The space will be designed for wheelchair
The space we have available to layout our kitchen and bathroom is approximately
16 feet by 24 feet; there is also a wall height of 8 feet as well as a wall thickness of 3 ½ inches. Our
door is located on the south wall of the design and leading up to the door is a ramp that has a
minimum width of 32 inches. Looking left when walking into the door, an occupant can expect to
see kitchen appliances as well as counter stop space. Starting from the right side of the west wall
there is a refrigerator followed by a counter space with a prep area and microwave. There is then a
stove and oven, a sink and in between the two is a clean-up area. Logically, there is then a
dishwasher touching the west and north walls. The height of the counter top is 24 inches with a
depth of 22.5 inches. Directly in the middle of the kitchen is a dining table with a seating of 6
people. The bathroom is approximately 7’ 3” by 8’. When walking through the bathroom door, the
roll-in shower will be directly in front. The sink is next to the roll-in shower on the north wall. On
the east wall, there is a water closet and bath tub.
Results and Discussion
Designing a kitchen and bathroom is quite easy. Designing a kitchen and bathroom that is ADA
approved is a little more complicated. The specifications according to ADA Standards:

A grab bar 24” long minimum shall be installed on the
control end wall at the front edge of the bathtub.
