First floor bathroom vent

My friend is thinking of putting a half bathroom on the first floor of their apartment.  He was thinking of venting it to the bathroom on the 2nd floor, which is directly above.  The 2nd floor bathroom is in turn vented via a skylight in the ceiling above. Would these plans be acceptable to the Dept. of Buildings?  My architect believes this is the most practical solution.  Thanks for the input.

Doesn’t sound right to me.  I think the vent duct would need to penetrate to the exterior.  In your case, it sounds like the shaft is still inside the building, with a skylight at the top being the only ventilation for that shaft.  If that’s the case, and the second floor bath opens directly onto that shaft, then every time the first floor bath fan is turned on, it could force the air (odors, moisture, etc) into the second floor bath.  It’s different in a tenement in that the tenement air shaft is open to the sky, with no skylight.If I’m understanding your question right, then I would not suggest it to any of my clients.

Yes, they would like to vent into the shaft.  The shaft/skylight is open to above in the second floor bathroom.  The vent from the half bath on the first floor would be ducted to the open to above shaft/skylight in the second floor bathroom.  Would this be allowed?  In tenement buildings, bathrooms are allowed to be vented by a window into a ventilated skylight shaft. Would duct work for a bathroom be allowed to vent into a ventilating skylight shaft?This situation is different in that it would be mechanically ventilated into the shaft and that the shaft/skylight in the full bath on the second floor is open to above.

If he wants to vent into the shaft, not below the skylight.  It sounded like they wanted to vent into the bathroom.

The person is thinking of taking the half bath first floor vent straight up to the shaft/ventilating skylight in the ceiling of the 2nd floor bathroom.  In other words: Would the duct work of the half bath on the first floor be allowed to vent into the ventilating shaft that is in the ceiling 2nd floor bathroom above?

No, the vent would need to go to outside.  You want to vent the lower one into the upper one?
