thanks in advance....my question is: i am doing a 2 separate additions to two separate buildings. both have an existing non-compliant restroom. one project owner wants a new accessible restroom, the other owner does not feel they need a restroom. the former is a doctor's office(556sf addition), the latter is a (930sf addition)drive-through oil change service building.
both projects increase the occupant load above 15 occupants required in "new construction" for separate facilities. but i can't find in the code where it states that when doing an addition, that the new occupant load must be added to the existing occupant load. the IEBC states the existing building does not have to meet the requirements of the current code, just the addition.
in either case, the addition needs only one restroom....would the existing restroom be sufficient? have i been reading the code wrong requiring people to bring the existing up to current code and occupancy calcs. when i can't find the passage in the code requiring it?
any help on this would be greatly appreciated
