Subfloor thickness under carpet

4709 Views 1 Reply 1 Participant Last post by  Avramel
Hi, I have 7/16 OSB that was installed in an unfinished space when my house was built (about 15 years ago). The joists are 16 inches apart. I am now finishing the space and will be putting carpet into the room.

Is there anything in the building codes that would indicate putting in a thicker subfloor? Am I asking for trouble by using the existing subfloor? Thanks!

Answer from Building Inspections Department

Talked to the local Inspections Department. They quoted code to add a 1/4 inch plywood or osb layer over the 7/16 osb and I would be good to go.
