Is 5/8 drywall required for ceilings or the exterior walls of a house? Is it required for ceilings when there is living space above the ceiling? etc. When is it acceptable to use 1/2 for a ceiling or the rest of the house? Is 3/8 ever acceptable on an interior wall?

I did google this 5/8 drywall ceiling new york but I didn't see the answer. I googled a bunch of different things and it seems to be "it depends." Can someone site the code used in NYC (specifically I'm thinking of Queens) and Westchester, and their interpretation of it? Thanks!

I'd be making a call to the local build department to be 100% sure.
3/8 would be usless on a wall, one bump and it will punch right through/
What's the spacing on the ceiling joist?

Have you looked at the county/city building code? These are usually available on line through the building department----

These vary from town to town-----so never assume anything with drywall thickness---always check code or go with 5/8 fire stop----

I'm not in your area but I always use 5/8 on a ceiling, Less screw pops and 0 sagging.
I also own a drywall lift, you can rent on. It can make it a one man job if need be.
The new light weight drywall can span 24" but I'm not willing to chance a sag, I only get paid once to do a job.
Is there an attached garage?

This is for some hurricane sandy disaster relief I'm doing, it's residences and not specific to a particular house. I checked NYC building codes but I don't see where any requirement for drywall thickness is. Westchester I haven't looked into yet. Thanks for all the advice so far

Deck, since you're in the area. Any idea where to get 54" drywall? I found one place in Elmsford, but they won't deliver the amount I need. So before I rent a truck, maybe you know. Thanks.

Since most ceiling joists are 24" on center 5/8" is used because anything over 16"oc 1/2" tends to sag over time. But as stated check you codes or a dependable drywall supplier can probably answer you question.
