Horizontal handrail extension at bottom of stair in Hawaii?

Can anyone confirm that Hawaii has no requirement for a twelve-inch horizontal handrail extension at the bottom of stair, just the diagonal extension for one tread width?

I know that requirements for the additional extension were removed in the 2004 ADA Standard and the 2003 ANSI 117.1 and that the IBC has never required it except by reference to ANSI 117.1. I've looked at the State of Hawaii's Amendments to IBC (2018) and can't find anything. Are there local requirements I haven't found?

Thanks!
 
Providing an additional 12'-inch extension beyond the one-tread-width sloped extension would not violate any federal laws or regulations. What he's referring to is the requirement from the original ADAAG for the bottom handrail extension to extend for a distance equal to one tread width on the incline PLUS an additional 12 inches horizontally. The requirement for the additional 12-inch horizontal extension has gone away, but providing it even when/where not required doesn't violate anything, since that 12-inch extension is beyond the required tread-width extension on the incline.

Section 1014.6 of the Hawaii building code does not require anything more than an extension equal to one tread width on the incline.

The Hawaii accessibility code adopts A117.1-2017. Section 505.10.3 likewise requires only the sloped extension for a distance equal to one tread width.

I can't address any local requirements in Hawaii.
 
Unfortunately (or fortunately, depending on your perspective) Hawaii does not provide thorough inspection and code enforcement services. I've been there a few times, and their lack of compliance is extremely evident. There's a local developer in my area that is building their retirement home over there and he was baffled at the lack of inspections. The inspector came for the foundation and told him flat out "call to schedule your inspections, but I won't be back till final." Businesses (especially large corporate ones) know they have to do it right to protect themselves, but they usually focus on the exposed elements that could result in lawsuits.
 
I see you are located in California. We have left that extra 12" in the California codes.
I agree that the extra 12" does not exist in the 2010 ADA standards. The only requirement in ADA is for a tread width extension.

Our handrail vendor (Jayco Hawaii) confirmed that a bottom horizontal extension is optional in Hawaii. Meaning there are no local requirements beyond ADA and IBC.

Thanks everyone for your answers.
