Heavy pans or canned goods need to be stored on bottom shelves within easy reach. Top shelving made of clear plastic makes it easier for a person in a wheelchair to see what's on the shelf. It's hard to do without bathrooms, and yet many residential bathrooms present a terrible obstacle for wheelchair users. Walls need to be reinforced by a technique called 'blocking' to accommodate the installation of grab bars that can support at least 250 pounds of pressure. Bathtubs, toilets and mirrors likely will need adaptations.
Some solutions are inexpensive and quick to implement.
Consider keeping electrical cords and telephone cords securely out of the way. Remove small rugs. Install nightlights in hallways, bathrooms and bedrooms. Install handrails on both sides of stairwells and light switches at both the top and bottom of the steps. Homeowners, home builders, and renters can find additional useful information in a publication from the American National Standards Institute titled American National Standard specifications for making buildings and facilities accessible and usable to physically handicapped people.
