Came across a one year old house today with a weird little add on room upstairs. The room was roughly 8 x 7.5 with a little 3 x 3 entry hall type thing. The room had a window on one wall and a built in shelf on another, but no closet. There was no HVAC supply vent.
The homeowner said that the room was sort of optional in the plans and that they had decided to go ahead and have it finished out with the shelves. He thinks there should be a supply vent and I agree. I see many closets this size on exterior walls that do have vents. I tend to think since the room was an option that the HVAC failed to get updated with the changes and/or simply forgotten.
Was looking for some sort of code or standard, if such exists, to back this up to help the client.
