I need to know the fire barrier requirements on an apartment complex for the ceilings, walls, walls that divide each individual apartment, and the floors.

Any help would be greatly appreciated!!

Most are 1 hour, some are 2 hour... Depends on the building type, and local adopted code, engineering, etc.

Most sets of plans that get stapmped by the city here will have wall and ceiling schedules, and paramiters laid out on a detail page. Like 'no openings in envelope over 16 sq inches' (7sq" in some places?), 100" of opening in 100'sq feet of wall', etc.

Here's a nice article by UL about boxes in walls, that I used for a class with my old crew... Most of this stuff is rule of thumb. http://www.ul.com/regulators/sepoct2000.pdf

You can only find the official answer by looking at the approved set of plans. The building official will have a set, and the construction contractor will have a set.
