The new Americans with Disabilities Act has some interesting technical changes. This Blog

will explain some of the changes. For a summary of the Scoping changes please read the

Summary of Technical Changes

Most of the technical guidelines are very similar to the original ADAAG, but there is a few

minor changes and additions to the entire document. Below are a few of the changes that

stood out.

1) In the new technical chapters the main changes is the re-formatting to meet the numbering

system of the ANSI. They have grouped sections together that make more sense, like all

plumbing fixtures under chapter 6.

2) New ranges where originally being absolute dimensions and lowering the existing ranges

are two new changes. For example they lowered the maximum height for side reaches from

54 to 48 inches (308.3.1)

3) Chapter 4 eliminates the texture and contrasting color for the curb ramps. This issue is being

addressed by the Department of Justice and will have new ruling from that agency. They also

are requiring a 36″ landing on top and bottom of the ramp.

4) The parking spaces and access aisle for vans has been changed so that instead of the van

accessible aisle to be 96″ wide, now it is 5′-0″ but the van space is 132″ wide.

5) They added a range to the distance for water closets from the wall to their center line and

made it 16″-18″.

6)The clear floor space at water closets is now only allowed to be 5′-0″ wide x 56″ min. It can

no longer share space with a lavatory.

7) Childrens heights for water closets were added

8) Urinals now have to be 13 1/2″ in depth to its rim from the mounting surface.

9) An exception allows for a parallel approach at kitchen sinks if there is no cook top or range.

10) Signage now has a range for mounting heights from 48″ to 60″ and an 18″ clear floor

space centered on the sign is required.
