What is the ADA regulation for the slope of a wheelchair ramp?
The ramp must have a 1:12 slope ratio. This means that there must be a one-inch rise in the ramp for every corresponding 12 inches of the ramp. Minimum width of 36 inches, although this can be higher in certain states.
What percent is a 1/12 slope?
8.33%
For a ramp the maximum running slope allowed is 8.33% (8.33% is a 1:12 slope).
How long does my ramp need to be?
The Americans with Disabilities Act (ADA) requires a 1:12 slope ratio for commercial ramps (ramps used in public spaces). This means that for every 1 inch of rise, 12 inches of ramp are required. For example, if an entryway is 36 inches high, you will need a ramp that is at least 36 feet long.
Does a wheelchair ramp need handrails?
Ramps must have handrails on both sides if their rise is greater than 6 inches or their length is greater than 72 inches. Cross slopes (areas where a ramp slopes sideways, perpendicular to the ramp’s length) must be less than 1:50, and surfaces must be slip-resistant and stable.
What is the maximum slope for a ramp without handrails?
Ramps having slopes steeper than 1:20 require handrails. Ramps with a rise greater than 6” require handrails.
How steep can wheelchair ramps be?
Maximum slope for hand-propelled wheelchair ramps should be 1″ of rise to every 12″ of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5″ rise to 12″ length (7.1 degree angle; 12.5% grade).
What are the ADA requirements for a handicap ramp?
Read more about ADA ramp slope requirements. Cross slope of ramp runs: Maximum 1:48. Handrail height: 34 inches – 38 inches from the walking surface. Handrail grip: 1-1/4 inch minimum to 2 inch maximum outside diameter for circular handrails. *For complete ADA ramp handrail requirements for California, view the California Building Code 11B-505.
How much clearance do you need for a wheelchair ramp?
Width: 48 inches clear space between handrails. Rise: The rise for any single ramp run shall be 30 inches maximum which means it can be 30 feet long maximum before you are required to have a resting platform. Slope: Maximum is 1:12 slope which means 1 inch of rise for every 12 inches of ramp run.
