From my hard learned experience use 3/4 inch sturd-I-floor which is a tongue and groove plywood for floor application. Apply glue to joists and tongue and groove. Screws are far superior to nails.

I am adding an addition to my home in RI. I am planning on laying carpet down over the subflooring. I am planning on using 3/4" CDX, the local inspector tells me I must use the tounge and groove sheets. I've built houses in other areas and never used T&G on them. What is the code and what is the best way to go?

*You are better off with the T&G plywood. It's a little more trouble to install but gives you a better end product. As for building codes, regardless of National or State codes which your locality may adhere to, there are usually amendments to these codes in each municipality that may not be consistent with other areas you have worked in.Pete
*JohnI recommed T&G also. It will prevent floor squeaking beteen 2 sheets. Also recommend gluing and screwing vice just nailing.Vince
