Benefits of Mezzanine calssification over storey

[Rwwon]

I understand the code outlines what qualifies as a mezzanine, but is there a list of benefits, reasons you consultant a client in choosing to comply with a mezzanine vs a storey. This is looking at it through the 2018 IBC.

One i can think of is it doesn't count towards allowable area, yet I think I read it does count towards fire area.

Unenclosed stairs has been my reasoning, and same criteria for mezzanize (in theatres at least) exempts it from being accessible. I am biased since my work is in assembly seating, mostly (performing arts) theatres and churches.

Good points. I would also add that if you have a limitation on number of stories, a qualifying mezzanine doesn't count against that.

So you are 1 of those people who prevent me from getting places with my wheelchair! Everybody keeps looking for ways to avoid complying with the ADA and this is a perfect example.

Well, everyone can be closer to the platform on the main floor with a third - mostly Easter and Christmas - in a mezzanine, or you can live with some of the wheel chair spaces further from the platform and a less good experience for all by forcing all seating to the main floor. (These projects often cannot afford elevators.) The higher volume - forced by the mezzanine - also provides better acoustics for everyone. Sightlines are generally improved, so people can see you when you're presenting or performing.
