The Americans with Disabilities Act (ADA) requires using ramps in public and commercial settings to provide accessibility for individuals using wheelchairs, walkers, and motorized scooters. This law has been updated over the years, but the core requirements remain to make public spaces accessible to all.

ADA Ramp Specifications and Requirements

Facilities must consider the location, size, and slope of ramps to comply with ADA regulations. The ADA specifies that any change in height greater than ½ inches along an accessible route requires a ramp unless an elevator or platform lift is used. For slopes of 5% or more, ADA-compliant ramps are mandatory.

ADA Ramp Design Standards:

  • Clear Width: The ramp must be at least 36 inches wide between handrails.
  • Rise: The maximum rise per run is 30 inches, with no limit on the number of runs.
  • Running Slope: The slope should not exceed 1:12 (one foot of rise for every 12 feet of ramp).
  • Cross Slope: A maximum slope of 1:48 is allowed.
  • Alterations: Limited space may allow for steeper slopes under specific conditions, such as:
    • 1:10 maximum slope for a 6-inch rise
    • 1:8 maximum slope for a 3-inch rise

Key Scenarios Requiring Handicap Ramps

  1. Public Buildings and Facilities: The ADA requires that public buildings, including government offices, libraries, and educational institutions, have accessible entrances, which often include ramps. This is crucial to accommodate all visitors and ensure equal access to public services.
  2. Commercial Establishments: Businesses that serve the public, such as retail stores, restaurants, and hotels, must provide ADA-compliant ramps if changes in elevation, like steps, could otherwise impede access.

  3. Residential Buildings: For multi-family housing, ADA standards may require ramps to make accessible units or common areas reachable. Although single-family homes are generally exempt unless specific conditions apply, ramps are often added to accommodate residents’ needs.

  4. Workplaces: Employers are required to ensure accessible workplaces, which may include installing ramps, to provide a safe and inclusive environment for employees with disabilities.

  6. Temporary Events and Facilities: Even temporary structures, such as those used for events or emergency facilities, must consider accessibility, including ramps.
