Introduce elevator for anything past 3000 sf?

[Ryan Schultz]

If you have a scenario, like the following, in a 1 story building, can the other (3) tenants build a mezzanine without a elevator?

Per 1104.4 I would think they could not, because the overall building already has a max 3000sf that is not accessible.

No, they may not. That is correct

 

[Paul Sweet]

They can't have a 3000 SF mezzanine in a 6000 SF space. IBC 505.2.1 limits mezzanines to 1/3 of the room area in which they are located. Another tenant can have the other 1000 SF of mezzanine.

There are exceptions...​
