Drywall Questions

Iím currently renovating a 1920ís duplex that will serve as rental property. For drywall, I will not be doing the work myself and instead using a contractor. Drywall will replace dilapidated plaster, which has already been completely removed, mostly in the ceilings. The specifications will be 5/8 inch drywall with 1 5/8 inch screws. The contractor has said I can use shorter screws 1 3/4 inch but will go with the longer screws. These specs meet local code. Although the code does not require it, I am wondering if itís a good idea to use "fire-code" drywall (called Type X) instead of regular drywall. Iím more focused on weight on the stud system of the old building rather than cost as a consideration. Looking forward to your feedback. If you have any other thoughts i.e. on thickness and length of screws, I would also appreciate them.

I would assume code would call for firerock between the units. Are you using 5/8" everywhere?

Unless it's a fire brake wall/ceiling then you dont need 5/8 or special drywall.

If you want to save weight go with 1/2"

Am I missing something? 1 3/4" is a longer screw than 1 5/8".

The walls between the units will not be replaced. Yes 5/8 everywhere and you folks are right will use 1 5/8 not 1 3/4. Is all this OK?

1 5/8" will put 1" of screw into the stud, this is fine.

The only place 5/8 is needed is between the units and on the ceiling.

I would use 1/2" drywall everywhere other than where firecode 5/8" is required. No need to add the extra cost. I'd rather spend that extra couple hundred $$ on something that someone will actually see.
