ADA Handrail Guidelines

1. You can install ADA handrails using various design

applications such as those for stairs, ramps, and

horizontal inclines. Designs include options for

straight and 90° wall returns, 90° corners, and

adjustable angles. Choose which is best for your

needs before installing.

2. The handrail system top rail should be 34"

(86.4 cm) to 39" (99.1 cm) above the surface.

However, verifying height requirements with local

building code ofﬁcials before installing is important

as codes vary in different areas.

3. Maintain a minimum clearance of 1-1/2" (3.8 cm)

between the handrail and any obstructions above

or behind the handrail.

4. The end loop return at all landings must extend

12" (30.5 cm) past the end of the ramp or stair

application.

5. The slope of the handrail for the ramp should not

exceed 1" (2.5 cm) rise over a 12" (30.5 cm) run.

6. The maximum recommended span between

supports is 6' (1.83 m) on center.

7. For ramps and stairs, cut railings along with the end

loops and/or post returns to the proper angle using

a miter saw to ensure proper ﬁt.
