I have a project in Texas that is under the IPC. This is a small tenant improvement for a "B" occupancy professional business office (stock broker) 3,652 SF. We originally submitted fixture calculations based upon 1 occupant per 100SF of the gross suite area which resulted in 37 occupants. This yields two single occupancy toilet rooms for this suite area.
The plumbing plan reviewer is requiring that we match the occupant load that we have calculated for exiting. There is a lobby and a conference room as a part of the suite. We calculate these areas for exiting at 1/15 as an Assembly occupant load. These areas are still considered B occupancy as the occupant loads are less than 50. The issue is that this really increases our occupant load for the plumbing fixtures to 92 occupants and requires additional plumbing fixtures.
Is this how you all calculate plumbing fixtures under the IPC? This is one area where California is less stringent.
Exiting occupant loads are essentially halved for plumbing fixture calcs under the CPC.
The part that is difficult for me to accept is if this was a proposed office building that did not have a tenant then the calculation would for sure be based upon 1/100 multiplied by the gross square footage of the space. Our tenant would then come in and the TI would be completed and no additional toilet fixtures would be required.
