7. ADA Guidelines and Local Codes
The Americans with Disabilities Act (ADA) is a civil rights law that prohibits discrimination based
on disability. Signed into law in 1990 by President George H.W. Bush, it sets standards for access to
public spaces and buildings, among many other protections. Within the ADA are guidelines for safe
ramps.
These guidelines are required for commercial and public properties. While not mandatory for
residential properties, each requirement serves a useful function, and National Ramp encourages
adherence to the below guideline summaries as much as feasibly possible.
At the door, there must be a flat surface at least 5' long, with a width at least as wide as the
ramp if the ramp extends straight out. When a turn at the door is required, the flat surface
must be at least 5'x5'.
ƒ
This guideline ensures users and caretakers a safe, level surface to open/shut their
doors and turn around before continuing onto the ramp.
ƒ
This level surface can be a porch/deck, and sometimes only a small threshold ramp is
needed to help navigate through the doorway.
Ramps should have a 1:12 pitch, so, for every inch of elevation, there are 12 inches of ramping,
resulting in a 4.8˚ slope.
ƒ
This guideline is to ensure the slope of the ramp is not too steep for safe passage.
ƒ
National Ramp recommends no greater than a 1:8 pitch/6.4˚ slope, and only for users
in a power wheelchair or manual wheelchair being pushed up the ramp by a caretaker.
Refer to the mobility device’s Owner Guide to confirm its maximum allowable slope.
Resting platforms of 4'x5' or 5'x5' are needed for every ramp run longer than 30'.
ƒ
This platform gives the user/caretaker a resting place in case they become weary when
traveling the ramp.
Ramps should end on a hard, level surface.
ƒ
ADA guidelines for a landing are five feet long, with a width at least as wide as the
ramp for straight landings, and 5'x5' minimum for a landing that changes direction. This
guideline is so the mobility device does not become stuck in muddy or soft ground.
