I have a proposal for a basement "speakeasy". Basically a small bar, under an existing A-2. The main issue is the fire suppression...or lack thereof. There are are a lot of moving parts and circular references to this but the one thing this keeps coming back to for me is the fact that what we have is a two story A2, N/S, type VB building.
If the space is currently an S-2, and will change to a small bar qualifying as a B due to it's small size and occupant load, the C of O is not to a higher hazard per IEBC 1011.5. The result would be a B under an A-2, which is still questionable but palatable since technically the hazard is not higher?
Here is the real rub: The two spaces are connected by a communicating stairwell, not separated, and will not operate independently, so I think the designation as a B is out since it is now an extension of the A-2 to a lower floor. The result is a larger A-2, spread to another floor, adding to the problems already present in a the A-2, N/S, VB, two story building.
Bottom line is this: Is this DOA since it is a two story with the A-2 on the "second story"? The A-2 above is the level of FD access. Does this help?
If permitted, we could end up with and A-2 with 40 people in the basement, with a single exit, connected to a larger dining and drinking establishment above, being operated as one establishment. Does this fly?
Code and commentary seem to conflate stories and stories above grade plane. 2018 IBC 504.4 says "maximum number of stories of a building", while the commentary says "the height is in number of stories above grade plane"
If we follow the code language, then this wouldn't be permitted as a two story building. If we follow the commentary, then since the A-2 is on the first story above grade plane, is this permitted?
Why me?
