A S2 storage building is being built behind a church. I'm doing the final inspection. No plumbing, heat or electric. Minimum plumbing are required for the S2 building so they can use the ones in the church. I did not get in it but It's a very old church with many steps to get in it , I was told it may just have one small toilet room so I doubt that it has the minimum required for the church or is accessible. Would the occupant load of the existing church need to be calculated along with the new storage building for the minimum plumbing fixtures required plus separate sex restrooms?
New 2,400 sq ft storage building occupant load would only be 8 if you go by the table for means of egress. But even if it was just 1 it will probably mean a big upgrade in the plumbing facilities in the church maybe even including upgrading the sewer line.

I'm not talking about accessibility here, but it will be an even a bigger problem. If they need do alterations to the existing toilet rooms and use part of the main use area to expand the restrooms or add restrooms it would trigger the IEBC accessibility sections and make their problems even worse.

The no electric in the storage building for egress lighting will be the easiest thing to fix.
 
No good code path for that particular situation, but you may be able to use the 20% logic....From change of use and alterations...

SECTION 1009
PLUMBING
1009.1 Increased demand. Where the occupancy of an
existing building or part of an existing building is changed
such that the new occupancy is subject to increased or different
plumbing fixture requirements or to increased water
supply requirements in accordance with the International
Plumbing Code, the new occupancy shall comply with the
intent of the respective International Plumbing Code
provisions.
Exception: Only where the occupant load of the story is
increased by more than 20 percent
, plumbing fixtures for
the story shall be provided in quantities specified in the
International Plumbing Code based on the increased
occupant load.
 
No Electric, Heat or Plumbing is not an occupiable building. Classify it as a "U" occupancy shed and be done with it.
Sealed plans call it S-1. I can not change this, it will be used as an S-1 building. Also zoning calls it a storage building. I don't know why if it was occupiable, heat, plumbing or electric or not has to do with it. Code has plumbing requirements for S-1 buildings no matter what's in it.

How can I use this? This is in the IEBC under change of occupancy.
This is not a change of occupancy or a alteration.
This S1 building is new. Only the church is existing where the plumbing is.
 
The same logic (ish) applies to additions:

1101.2 Creation or extension of nonconformity. An addition
shall not create or extend any nonconformity in the
existing building to which the addition is being made with
regard to accessibility, structural strength, fire safety, means
of egress or the capacity of mechanical, plumbing or electrical
systems.

If the existing fixture count handles the load, its fine....Just depends on how flexible you can be in your AHJ.....

Not sure how I can use this.
The S1 building is not an addition. It is a separate building on the same lot as the existing church. I am mostly worried about accessibility.
We can not have any flexibility at all with accessible codes in our state
