![]() If a landing is installed in a location that may become wet, it must be designed to prevent the accumulation of water. If the ramp does not change directions at the landing, the landing must be at least five feet long and at least as wide as the wheelchair ramp. If the ramp changes direction at the landing, the landing must have minimum dimensions of five feet by five feet. LandingsĪll wheelchair ramps must include an appropriate landing at both the top of the ramp and the bottom of the ramp, and each landing must be level. After 30 inches, a rest or platform must be provided. ![]() ![]() RiseĪDA regulations require a maximum ramp rise of 30 inches. Keep in mind that some states may have stricter requirements than the ADA. This space must be clear and free of obstacles. Whether a wheelchair ramp is portable or permanent, the ADA requires a width of at least 36 inches between the ramp’s handrails. The cross slope, which is the slope running perpendicular to the user's direction of travel, should not be any steeper than 1:48. Anything steeper is considered dangerous. SlopeĪccording to the ADA’s specifications, the slope in the direction of travel cannot exceed 1:12, meaning that for every one inch of rise, there should be 12 inches of length. These requirements apply to almost every aspect of wheelchair ramp design, from the slope of the ramp to its length, and they can be complicated, so it is usually a good idea to work with an experienced contractor when installing a wheelchair ramp in any location. The ADA's requirements outline the proper shape, size, slope, and design of wheelchair ramps and other building components so that they can be safe and accessible for people living with disabilities. We’ll help you understand the ADA's guidelines so you can make sure that the design of your wheelchair ramp is compliant, whether you are installing it in a commercial location or at your home. The Americans with Disabilities Act (ADA) publishes specific guidelines that apply to the design and installation of wheelchair ramps, setting standards that must be adhered to in order to ensure safety and accessibility.īut how do you know exactly what you need to do to make sure your ramp meets these standards? We’ll walk you through the guidelines to make the whole process clear, easy, and transparent. While there is some amount of crossover, interior stairs have their own code requirements.Wheelchair ramps are an essential component of mobility for people who use wheelchairs and other assistive devices like scooters or walkers. It should be noted that building codes and regulations for exterior stairs are not exactly the same as those for interior stairs. They can be styled in a variety of ways as long as they provide adequate space for a hand to grip them. Rails must be able to support a load of at least 200 pounds and must extend at minimum 12 inches horizontally past the riser nosing at the top of the stairs and at least equal to one tread depth horizontally at the bottom of the stairs. The associated railing height code states that these rails must be placed between 34 and 38 inches above the walking surface of the stairs. ![]() This applies to any staircase with two or more risers. While the finer details will ultimately be influenced by your local government's building regulations, the International Building Code, the International Residential Code and the standards set by the Americans with Disabilities Act of 1990 maintain that exterior stairs that are a required point of egress – in other words, stairs that must be crossed on your way in and out of the building – must have handrails.
