Hole in the side of our building for a bath vent?

…so our building is at the end of a block which means the back yards of the buildings on the main street run perpendicular into the side of our building. We’re moving a bathroom on one of our floors, (and yes, it will all be filed properly), but a big difficultly for us will be running the exhaust vent (_not_ the plumbing vent stack) to the outside. The thought crossed my mind that it would be so easy to simply vent it out the side of the building through the brick. Given the fact that the hole would only be 4″ diameter or so, I cant imagine it would cause any structural issues, and we would of course talk to our neighbors about it (we’d probably need access to their back yard, unless the guys went down from the roof on ropes). It would probably be about 10′ high, so not in a sight line. In fact, the neighbors have a big ugly telephone pole in their backyard next to our building, and we could probably put the vent right behind it 🙂 I’m imagining that such shenanigans are not allowed, but I was wondering if anyone could confirm or deny it? The building is not landmarked, FWIW. Thanks.

We have been told that no new vents are allowed vertically, and all must go up and out.

Your vent must face your own property. It cannot vent to the yard of an adjoining property no matter how small you think it is.

Is the wall that you want to vent through on or near a property line?
