Author Question about building code and walls in basement...

I have 9 foot walls in my basement. I intend to put a drop ceiling in
at 7.5-8 feet.

If drywall is stacked vertically at 8feet tall, there will be a gap
above the ceiling between rooms.

Putting sound-proofing etc aside, does anyone know if code allows this
gap, or do all rooms have to be sealed from one another above the
ceiling? I already have a lot of mechanicals (ducts, gas lines etc)
running thru this space so some areas cannot be sealed with drywall.

I am checking with local code, but wanted to get a general idea
first...

What code? If you mean local codes, I think you need to tell us where
the house is.

One problem that I imagine you'll have is with electrical items. It sounds
like you plan to put a ceiling in the basement. I believe that no junction
boxes are allowed in the area above a dropped ceiling. Except for runs of
wire, any box or splice, etc. must not be covered. As mad hatter wrote, you
need to check your local county or city codes for correct info.

Junction boxes can't be placed where they can't be accessed, ie sealed
inside a smooth ceiling or inside a dropped ceiling that is
sheetrocked. I will be using acoustic tiles.

OK, Gwinnett County, GA.

Why? Nine foot ceilings do wonders in removing the "basement feel".

Yes.

No.


Checking with your local codes will confirm this.
