I'm looking at finishing off my basement to use as an office and have several questions. Due to limited finances I'll probably end up doing most of the work myself.
House is about 20 years old and is in north metro atlanta. 2 basement walls are a concrete foundation and are concrete all the way up. A 3rd wall is running down a slope and starts with concrete all the way up and then finishes with concrete only half way up and wood construction the rest of the way up.
The last wall is an interior (of sorts) wall to the garage.
I'm thinking of finishing off 1/2 and putting in a dividing wall. The half I'm looking at finishing would *not* include the 1/2 foundation wall.
I've been in the house for 4 1/2 years and have never seen any evidence of water. After a big rain though you can feel that the air is more humid.
My questions are
1) In various places I see the advice "check with your local building codes". How/where do I go about doing this? One code item in question is ceiling height. I have exactly 8 feet from the concrete floor to the bottom of the floor joists so obviously my finished floor to ceiling height will be somewhat less. In fact I'll have to make it probably a foot less in a few isolated area to deal with some sewer drains and hvac ducts.
2) I've seen varying advice on proper wall insulation and construction. Are there any problems with using construction adhesive to put up 1/2" foam and then put up a standard 2x4 stud wall using a pressure treated base plate? I'd then put fiberglass insulation between the studs after wiring.
3) There are some doorways right now where the structural part of the frame are made with kiln dried 2x4's. The bottom edge touches the concrete floor. Is this a problem? I thought you needed pressure treated for all wood contacting the concrete floor?
4) Assuming my construction details in #2 are correct, whats the right thing to do right at the top of the walls? The concrete foundation wall stops a little below the bottom of the floor joists. There is a piece of wood lying on top of the foundation wall and the floor joists then rest on that. Do I just stop the foam at the top of the foundation wall and then stuff in fiberglass? Or should that area stay hollow?
5) I was thinking of using ceiling tiles to make it possible to access things like phone lines down the road in case I needed to. That way I wouldn't have to tear out drywall. Then again, maybe with some planning I can avoid that need. Any thoughts on a drywall ceiling vs a suspended ceiling? Actually the ceiling may have to wait because I'm on a bit of a hard schedule here and I may need to occupy some of this space as an office before it is fully completed.
The timing of this couldn't be worse since I still have probably a month to go on a major bathroom remodel upstairs, but such is life.
Thanks in advance
