ADA & OSHA Compliant Ramp Guidelines: Construction & Safety

Ramps provide access to buildings that otherwise require a person to be able to climb stairs. The Occupational Safety &Health Administration provides guidelines for ramps, which reduce the risk of injury and improve accessibility for wheelchair users and people with limited mobility.

Incline

• Per OSHA standards, the maximum slope of a ramp should not exceed 20 degrees from horizontal. This is a ratio of one vertical to three horizontal.

Length

• Due to the above restrictions for maximum ramp incline, the length of the ramp may be significant. Handrails can provide support for people walking along a ramp. Landings can be provided along the length of a ramp providing a level surface where an individual can stop and rest.

Exception

• Due to inadequate space, the above requirements may not be met. If a ramp must exceed a ratio of one vertical to eight horizontal, OSHA requires that cleats are installed along the ramp at least every 14 inches to make the ramp more safe.
