In Residential work is the Bathroom Fan vented directly to the outside or just into the attic?
I've seen a lot that just vent into the attic. Upon exploring our New NY Residential code (based on 2000 IRC) it seems that they must be vented directly to the outside. (R303.3 Exception) Is this a new requirement?
Hi Bill and Pierre, in the south in the 70's and 80's it was common to just vent into the attic. I don't know if it was just an ignored code or not. Sometime in the 80's it was changed or atleast enforced to vent all the way to the exterior.

Many times I've seen the vent hose pointed towards a vent in the attic, but not actually breaking through to the outside. I was actually surprised to see the requirement there.
IMO; in NY the existence of Building codes is still a new idea to most in the Electrical field. Until the recent adoption of the International Codes I had never seen a NY Building Code and still have no idea where the old ones were sold.
We sell the codes in our 'Store' here so I have access to all of them, but I have a copy of the Residential at my desk that I've tried to look into from time to time. I also have a copy of the New 2003 International Existing Building Code that I'd like to delve into when I get a chance just to see what might be coming.
Do you know if the numbering system in the NY codes follow the International codes? I keep forgetting to get the books side by side to compare them.
