Guide to ADA Compliant Ramps

Erickson AsphaltJuly 14, 2023

Ensuring accessibility is not just about convenience; it's about creating an inclusive society that caters to the needs of all individuals. The Americans with Disabilities Act (ADA) is a landmark legislation that promotes accessibility for people with disabilities. One crucial aspect of ADA compliance is the construction and installation of ramps along with ADA compliant parking spaces.

Understanding ADA Regulations

The Americans with Disabilities Act (ADA), enacted in 1990, is a landmark civil rights law that prohibits discrimination against individuals with disabilities in all areas of public life, including employment, transportation, and public accommodations. Title III of the ADA specifically addresses the requirements for accessibility in public accommodations, which includes businesses, schools, and government facilities.

Why are ADA Compliant Ramps Necessary?

ADA-compliant ramps are essential for promoting accessibility and inclusivity within public and commercial spaces. These ramps enable individuals with mobility challenges to access buildings, sidewalks, and other areas with ease, ensuring they can participate fully in society. By providing ADA-compliant ramps, businesses not only meet legal requirements but also demonstrate their commitment to creating an inclusive environment for all customers and visitors.

Ramp Slope

One of the critical factors in ramp design is the slope or incline. ADA mandates that the maximum slope for a ramp is 1:12, which means for every inch of rise, there should be 12 inches of ramp length. For instance, if your ramp needs to rise 12 inches, it should have a minimum length of 12 feet (144 inches). The slope needs to be consistent across the entire length of the ramp. Additionally, cross slopes cannot exceed 1:48 ratio. This ratio ensures that wheelchair users and individuals with mobility devices can navigate the ramp safely and comfortably.

Clear Width

The ADA guidelines also specify the minimum clear width of a ramp. The minimum width should be 36 inches, allowing ample space for wheelchairs and scooters to maneuver comfortably. In certain circumstances, a wider ramp may be required, such as when the ramp serves as an exit route or during high traffic areas.

Landing Platforms

Landing platforms are level areas that provide users with a resting point when using a ramp. They are crucial for safety and usability. ADA requires that a landing platform be at least 60 inches long and 60 inches wide, measured in the direction of travel. If the ramp changes direction at a landing, the minimum clear width should be 60 inches for both directions. The platforms can not change level more than 1:48 ratio. Finally, platforms should be built with proper drainage to prevent water accumulation.


Handrails play a crucial role in providing support and stability to individuals using the ramp. According to ADA guidelines, ramps with a rise greater than 6 inches or horizontal projection greater than 72 inches must have handrails on both sides. The height of the handrails should be between 34 to 38 inches above the ramp surface. Handrails need are need on both sides of the ramp. Also, the rails must extend 12” into the landing platform.

Ramp Surface

To ensure a safe and slip-resistant surface, it's essential to choose the right material for the ramp. The ADA recommends that ramp surfaces have a stable, firm, and slip-resistant finish, such as concrete. Avoid materials like loose gravel, which may create hazards for wheelchair users.

Non-Discrimination and Safety

When designing an ADA-compliant ramp, it is essential to consider the safety and ease of use for all individuals, regardless of their abilities. The ramp should not impede or create barriers for anyone. Proper signage, contrasting colors, and clear pathways are equally vital to ensure a universally accessible environment.

Creating ADA-compliant ramps is legal obligation for property owners. By constructing ramps that adhere to ADA guidelines, we ensure that people with disabilities can move independently and confidently. An inclusive environment benefits everyone and reflects a society that values diversity and accessibility. So, the next time you design or install a ramp, keep the ADA guidelines in mind and take a step forward in building a more inclusive world for all.
