Anyone familiar with residential building codes for Monroe/Wayne County, NY?
I need to check how big the ceiling joists should be. I've heard from
people at Lowe's and Home Depot that they need to be at least 2x6. I was up
there installing a couple of bathroom exhaust fans and they are 2x4s...
I suspect these are not joists, they are the bottom chord of manufactured
Are there "W" shaped 2x4s (or similar triangle shapes) connecting the bottom
and top members?
If so these are trusses engineered for your application. They do have a limited
load carrying ability on the bottom chord, typically a couple PSF. It is
usually just enough to carry the drywall, insulation and occasional entry by a
worker. They are not intended for storing heavy stuff in the attic.
Yes, you're right. All of them (including top and bottom) are 2x4s.
I need to replace the baffles in the attic which are made out of thin
cardboard and are falling apart (humidity? lack of ventilation?). I will
also at some point blow in more insulation to increase the R-value. I'm 195
lbs and will be making quite a few trips up there, besides the several trips
I have already made.
So you are saying this is code then.

Just don't step through the ceiling.
Some people make a 'catwalk', with
boards or a heavy enough plywood cut at
16" so as to get three strips per sheet. That goes
along the trusses to allow movement from one end to
the other. If you decide to do it, and plan to add more
insulation later, I suggest 2x4 or 2x6 spacers.
Put some lights up there too.
You should be OK working in the attic as long as you stay on the 2x4s.
People have been storing things in the attic with no ill effects for decades
too, although trusses were not designed for it. Putting plywood down actually
helps that since you are spreading the load out but if you do get it too heavy
you will see stress cracks in your ceiling drywall. Interior walls are
generally not designed to be load bearing in a "truss house" but they do tend
to carry some of the load so bear that in mind if you do store things in the
attic. Just limit yourself to light items like christmas ornaments, not your
rock collection. ;-)
There are no building codes in Wayne County.
About 10 years ago I looked at a new house at East Bay. It was framed with
2x4s. I asked the realtor about it, but she just shrugged.
I called the building inspector because it obviously didn't have enough
insulation. He was unaware there was a state requirement for minumum
