Single 5" Step in Portion of Existing Building - ramp required? (California)

[Yikes]

...you cannot exit across a single riser.

I think 1003.5 exceptions #1 and 2 describe specific instances when exiting is allowed across a single riser.

Absolutely they do. My assumption is not any of the uses in exeption #1. and not enough info to determine #2

Long discussion with many points but if I can enter a space I must be able to exit it. Required exits must be accessible.

If the shutter opening is for deliveries only is considered a pass through window then maybe you might have an out.

There is a single 5" step for a portion of the existing commercial building. The area is about a third of the floor area but not considered a primary function. Are there any exceptions for providing a ramp for the single step? The work done in this inaccessible portion is limited to structural repair and skylights.

I see there are a few exceptions. Notably the following:

(CBC 1003.5) Elevation Change A stair with a single riser or with two risers and a tread is permitted at locations not required to be accessible by Chapter 11A or 11B
(CEBC 305.6) The altered element or space is not required to be on an accessible route, unless required by Section 305.7.

Cali you need to look at the ADA. The DOJ will be the ones going out there to find violations. Or some attorney who knows someone with a disability who could not get into that portion of the building with the step. If that portion of the building with the step prevents someone in a wheelchair from entering a public accommodation that other folks can, you will be in violation of the ADA. California inspectors are not going to cite you. I hope their plan reviewers do ask for changes to comply. Existing buildings are also under the Barrier Removal section of the ADA.
