I think I expected to nail my 7/16 sheathing 6" OC at the edges and 12" OC at intermediate rafters, but…my city (Anaheim) doesn’t specify what they’re looking for in the permit application, and instead refers back to CBC Table 2304.9.1 (the fastening schedule).
Towards the end of this schedule, in the section talking about Wood Structural Panels and Particle Board, it talks about nailing 4" OC at the edges and 8" OC at intermediate rafters when the sheathing is under 3/4" in thickness (condensing down what it says quite a bit here). Am I reading that correctly? It seems excessive to me, and I know excessive fastening can be a bad thing.
Would it be presumptuous to call the city and find out what the Building Inspector would be looking for? I absolutely want to get this right - if I were to nail 6" OC there is no way I could go back and do 3" - THAT would for sure be excessive nailing.
Another thing is galvanized nails vs. bright. The schedule doesn’t call for galvanized (or at least not that I can see), but I’ve read from other posts that’s what you guys tend to prefer using. The only trouble…I was thinking of going to a 3" nail, on account of having to go through existing spaced sheathing too, but I’m having a dickens of a time finding wire nail coils for my Hitachi gun.
Sorry to be such a newb! I promise you, I have the rest of it pretty much under control.
