Hello, I'm an architect working on a design for a new firehouse. Due to site constraints, it may have to be a 2-story design with offices and living quarters over the garage. This presents building code / expense issues with regard to use separation, and concerns on exhaust fumes, although we will be using a Plymovent exhaust system.

Are there any other concerns that should be taken into consideration with a 2-story design (obviously response is one) but I'm referring to physical issues.

Thanks in advance for any thoughts.
