Use local code and accessibility guidance for slope, landings, width, handrails, drainage and surface. Avoid improvised steep ramps and confirm the chair/vehicle turning space.
What this means in real life
A safe ramp must match the user, mobility device, site and local code. Slope is central: steeper ramps require more power, traction and caregiver force and increase tipping or runaway risk. ADA design guidance commonly uses a 1:12 maximum slope for many new ramps, but private-residence rules and site constraints vary; longer, gentler ramps are often easier and safer.
Include level landings at doors and turns, adequate clear width, edge protection, handrails where required, a nonslip surface, drainage, lighting and enough space to open the door without rolling backward. Thresholds and the path from parking to ramp matter. Portable ramps must have sufficient length, load capacity, secure placement and safe storage; short improvised boards are dangerous.
Have a qualified accessibility contractor or local code official review structural support, frost/soil conditions and permits. Test turning with the actual chair before finalizing.
A practical checklist
- ✓
Measure total rise, available run, doors and turning landings.
- ✓
Use local code and recognized accessibility guidance.
- ✓
Specify load capacity for chair, user and caregiver.
- ✓
Add drainage, lighting, edge protection and nonslip surface.
- ✓
Plan snow/ice care and an alternate emergency route.
Questions to bring with you
Use these at the clinic, school meeting, equipment evaluation, program interview or benefits call. Write down the answers and who owns the next step.
- What slope will the actual device and caregiver manage safely?
- Can the door open while the chair remains level?
- Are handrails and edge protection required?
- How will water, snow and leaves be managed?
- Does the structure require a permit or engineered footing?
Important context
Individual needs, eligibility and safety can differ. Confirm the plan with the relevant Duchenne-experienced clinician, therapist, school team or program before acting.
