Understanding ADA Requirements for Parking Lots

For paving contractors, it’s crucial to understand the laws surrounding accessible parking spaces and their associated requirements. These regulations are designed to ensure accessibility for individuals with physical impairments and compliance with legal standards. Being prepared with the right paint striping equipment and tools ahead of time can streamline the process and help you meet these requirements effectively.

The Americans with Disabilities Act (ADA)

Enacted in 1990, the Americans with Disabilities Act (ADA) introduced comprehensive regulations to eliminate discrimination against individuals with disabilities. Among its provisions are specific accessibility standards for parking lots and garages, ensuring these spaces provide equal access for everyone. But what exactly are the ADA requirements for parking lots?

Accessible parking begins with proper planning. To comply with ADA standards, parking facilities must have a designated number of accessible spaces based on the total number of spaces available. Every lot is required to have at least one accessible space, and for every six accessible spaces, one must be van-accessible.

Four Key Requirements for ADA-Compliant Parking Spaces

  1. Dimensions
    Accessible spaces must be at least 8 feet wide, with an adjacent access aisle of the same width. This design provides enough room for vehicles equipped with ramps or lifts.

  2. Pavement Markings
    While the ADA doesn’t mandate marking each space with the universal accessibility symbol, it’s a widely accepted practice. The adjacent access aisle must be clearly marked with yellow diagonal lines to indicate that it’s not a parking space.

  3. Pavement Slope
    Accessible spaces must maintain a slope of no more than 2% in any direction. This ensures a level surface for ease of movement, with no more than one inch of vertical change for every 50 inches of horizontal distance.

  4. Signage
    All accessible spaces must display the international symbol of accessibility on a sign measuring at least 12 by 8 inches. Additionally, signs should include a warning about fines for violations (up to $200 in many cases). The signage must be centered in front of the space and mounted 60 to 66 inches off the ground for visibility.
