Considerations for Adapting a Home for Wheelchair Accessibility
?There are several ways to create a more accessible space for a person in a wheelchair. Some options include altering an existing floor plan, building an addition, converting existing rooms, renting a different apartment or home, or buying a new home. The following guidelines may be helpful to anyone planning for wheelchair accessible housing.
Please consult with a qualified Home Modification contractor to ensure full compliance with applicable laws and regulations.
Always measure the width and length of your wheelchair since there are many different sizes.
The dimensions listed below refer to standard-size wheelchairs. Owners of power and reclining models may need to modify the measurements based on the length and width of the chair. It is important to identify specific needs.
General Building Blocks for Adapting a Home
- Minimize and eliminate changes in floor level/transitions
- Provide ample turning space in all areas
- 67 inches in diameter is the recommended standard (International Code Council standard 304.3.1)
- Consider knee/toe clearance under vanities, sinks, work surfaces, eating tables, etc.
- Decrease clutter and provide clear floor space for a wheelchair in all spaces of the home
- Consider height of all appliances, shelving, outlets, etc. to be within reach range from wheelchair level
- Change doorknob hardware to be more accessible (i.e. lever handle)
- Install a ramp or stair lift to enter the home if necessary
Entrance and Exit
Parking: If you use a garage, make sure the entrance is high enough for a raised-roof van and wide enough to allow the use of a wheelchair lift or to make an easy wheelchair transfer. Approximately 96 inches is needed for a wheelchair lift and 60 inches of space is needed for a transfer from the wheelchair.

Specifications for a ramp or pathway to entrance
- 36-48-inch-wide pathways
- 32 to 36 inches high handrails that extend 12 inches beyond ramp
- Slip resistant surface (non–slip strips, indoor/outdoor carpeting, sand paint)
- Covering for inclement weather
- Ramp materials: wood, concrete, or expanded aluminum
- For every 1 inch of vertical rise, 12 inches of ramp
- Free swinging (no spring or hydraulic mechanism)
- ? inch or less threshold edge height
- Option: electric entrance door opener
- If a ramp is longer than 360 inches, it needs to change direction. With a change of direction, a level platform or landing should be used. The minimum landing size required is 60 inches x 60 inches.
- If there is no room for a ramp and/or the ramp is too steep or unsafe, a vertical lift or elevator may be used.
- Ask your occupational therapist or physical therapist for information on lifts, ramps and elevators.
Interior/General Living Space
Doorways
The minimum 36 inches of continuous clear width of accessible routes can reduce to 32 inches at points, such as doorways, for a maximum distance of 24 inches. Greater clearance is required for 180 degree turns around narrow obstructions and for wheelchair turning space. The minimum clearance cannot be reduced by any elements, including handrails or protruding objects.
**The exact width required depends on the width of the wheelchair. 32 inches wide is the standard minimum recommendation for doorways; however, measuring the width of your personal wheelchair is most important to guarantee proper mobility through doorways.
Options to increase the width of doorways:
- Offset, Z–shaped door hinges
- Remove the frame on the door
- Remove the door itself
- Reverse the swing of the door

Set Priorities before Starting a Modification Project
Most people work on the major architectural barriers first. Priority is usually: entrance, bathroom, bedroom, and then other rooms of the house. The permanence and quality of modifications depends on the needs of the person using the wheelchair and family, estimated time spent in the home, available finances, and whether the residence is being rented or owned. The following guidelines can help the modification process go more smoothly.
- To avoid over designing, recognize your abilities and disabilities.
- Ask other people with disabilities for advice. They can refer to reputable contractors and give suggestions based on personal experience.
- Know your individual needs. Analyze and operate all equipment before buying to make sure it works for you.
- Use a specialty or standard contractor.
- Try to solve problems with a minimal investment in time and money.
- Always review plans.
