So I've run into this a couple of places and I'm curious where other professionals land. You have a warehouse that has a mezzanine. Say the warehouse is 20'-0" tall and the height of the mezzanine is an even 10'-0".
You have 8'-0" of shelf storage underneath the mezzanine. You have 8'-0" of shelf storage on the mezzanine. You are protecting under the mezzanine separately, but the mezzanine does not make up the full floor area of the entire warehouse. So there are open areas where you only have 8'-0" of storage to a taller 20'-0" building. Does the storage over the mezzanine bring your storage up to 18'-0" or is it 8'-0" of storage? It's 18'-0" over the floor, but 8'-0" over the floor of the mezzanine. And there is protection beneath the mezzanine, but the storage under the mezzanine extends beyond the outline of the mezzanine. It's still only 8'-0" high, but now the ceiling height is different. Anyway, any input or thoughts would be great. Code references always appreciated. Sent in anonymously for discussion.

Depends how wide the mezzanine is. If it's under 15' then you have to cover it as if it was the adjacent hazard anyway so the area above the mezzanine is protected at 20' height requirements.

I would treat it the same as Anthony.

They are considered separate areas.
