Common Sense, ADA Guidelines and Your Home

Common Sense First

If the people using the ramp are going to walk or push themselves up in a wheelchair consider the 

individual’s strength and ability.  If there is an attendant consider the attendant’s strength and ability.  

Think a few years ahead.  Be sure to consider someone coming down the ramp.  What will happen if the 

attendant is startled and lets go?  It is also important to consider what the situation might be in several 


Even with a powered wheelchair, a ramp that is too steep can cause problems as battery output drops or 

the person gains weight.  Again, it is important to consider what the situation might be in several years.

How many other people will be using the ramp on a regular basis?  You may need to consider several 


ADA Guidelines

ADA Guidelines require a 1:12 slope, which is one foot of ramp for each inch of rise.  (Approx. 4.9 deg.) 

Slightly steeper slopes are allowed for short distances such as 1:8 for 3 inch rise or 1:10 for 6 inch rise

ADA Guidelines also require that a level rest section or turn be installed at every 30 inch change in

elevation.  This is so that someone ascending has a place to rest and someone descending easily

maintains a controllable pace.

ADA Guidelines require handrails for ramps over 6 inches above th ground.  Acces4U modular ramps

include handrails.

ADA Guidelines require a curb at the side of a ramp (Access4U ramps have this built-in)

For home use (single family residential) the ADA guideline may be varied to meet actual conditions

and user requirements.

Right, left and U-turns are used to direct the desired path of the ramp.  The standard right or Left turn is a

5x5 ft. (ADA) platform but for cost or space consideration a 4x4 ft turn is often used. U-turns,  are usually

5x8.  Turning platforms are installed level. 

Your Home

Consider all of the options, front door, back door, porch etc.  Where will the ramp start and where will it

end.  Are there fences, trees, lampposts, awnings or low branches that will obstruct the ramps’ path..

Measure the height difference between the start and end points.  The height difference becomes the

length of the ramp in feet. Platforms do not count in determining the length of ramp needed.  Refer to the

chart at the left.

Sketch an aerial view of the path of the ramp as if you were looking down from the sky.  Use rectangles

for ramps and squares for turning platforms.  Add the lengths of the ramps (not platforms in feet. This

should equal the overall elevation difference in inches measured above.  Most engineers sketch things

several times before final drawings.
