I initially posted this on the Building Codes Section when it probably would have been better to post it here.

Section 1007.2.1. In buildings where a required accessible floor is four or more stories above or below a level of exit discharge, at least one accessible means of egress shall be an elevator complying with Section 1007.4.

I realize there are a couple of exceptions. However assuming one chooses not to use the exceptions, and chooses instead to provide the elevator to satisfy the accessible means of egress issues, would you or wouldn’t you consider this elevator to be an “Occupant Evacuation Elevator” and subject to the provision of Section 3008.

I would agree that it isn't the intent of the code for able bodied persons to use the elevators. However it is pretty obvious that the codes feel that this service needs to be provided for the disabled when accessible floors are more than four floors above or below the grade level. It seems to me that the use of terms like accessible means of egress instead of avenue of assisted escape by first responders should be enough to show that it is intended to be used by the disabled without assistance. That typically is a big key in establishing equivalent access.

What is accessible means of egress for if it isn't evacuation for the disabled occupants? When items are provided for the disabled, it is with the intent to grant them equivalent access to amenities, in this case equal access to exit facilities. Just the fact that these elevators are required for means of egress (escape) of occupants ought to be enough to invoke Section 3008.

Why would they bother to reference Sections 403, 3007 and 3008 if it wasn't to direct you to elements of design that need to be taken into consideration?

The only other justification for not providing what is required for "occupancy evacuation" would be if you didn't consider the disabled to be occupants.

Thoughts on the subject?
 
These are the questions I submitted to ICC for an interpretation and the corresponding reponses I recieved from an ICC staff member on this subject. Thought you might be interested. I'm not saying I necessarily agree or disagree, but here it is.

Question #1: Is the accessible means of egress elevator intended to be for unassisted use by disabled occupants in the case of emergency or is it intended to be used exclusively by rescue personnel for the rescue of disabled occupants? It was always my impression that accessible carries the connotation that the element (in this case the elevator) should be for the unassisted use of disabled persons.

Answer: There are two separate requirements. Chapter 11 in Section 1109.6 requires elevators that are on an accessible route to be accessible (meaning they meet ICC A117) and meet Section 3001.3. At least one elevator shall be accessible (meaning it meet all the features and dimensions in ICC A117). Chapter 10 has the means of egress requirements. In a five story building, at least one elevator shall comply with the special means of egress requirements in Section 1007.4. I hope this answers your question. To answer your question, both.

Question #2: So my assumption then is that the elevator is intended to be an occupancy evacuation elevator, and as such needs to comply with the provisions of 3008. Is that correct?

Answer: No, Section 1007.2.1 has nothing to do with Occupant Self-evacuation elevators. Those elevators are only required in high rise buildings, and then only when the third stair is not provided on buildings over 420 feet in height. See Section 403.5.2 and 403.6.2.
