Do I need a nailing edge around the perimeter of my room for my new AdvanTech subfloor?
I did it both ways in a laundry/powder room I completed last year.

Along the one wall, I installed the nailing plates your described.



Along another wall, I didn't, in part because the sole plate for the wall had to be down before the subfloor, in order to run the plumbing. Also this area holds the washer/dryer &amp; a utility sink, so no foot traffic.



In any case, the inspector was satisfied.
