2010 ADA Standards for Accessible Design

ADA Restroom Mounting Heights

The 2010 ADA Standards for Accessible Design set where restroom accessories go, and an inspector checks them with a tape measure. This chart collects the heights for every accessory we sell in one place, each with the section number it comes from. Open any row for the full rules, how to measure, the mistakes that fail inspection, and products to check against them.

Every requirement on these pages is quoted from the ADA Standards issued by the Department of Justice, as posted by the U.S. Access Board. State and local codes can add to them, and the authority having jurisdiction has the final word.
