Years ago the San Diego Homeownership Center used to run a forum where you could ask FHA-related questions and get official responses back. It was their position at the time that a bedroom did not need a door or a closet, if someone needed privacy, they could hang a blanket and if someone needed a closet, they could purchase an armoire. I look at bedrooms in terms of functional utility. If a person has to traverse a public area (living room, kitchen, etc.) to reach a bathroom, then it is dysfunctional when used as sleeping quarters. We appraise floorplans in terms of "Highest & Best Use". What would be the most "functional" use for the room? Frequently those orphan rooms that are the result of garage conversions or afterthought additions demonstrate the highest functional utility when used as a "study" or even an "office" (if it has a door to the exterior where people can come and go without disturbing the occupants of the dwelling). Try to think like an architect, not a realtor. I've gotten into lots of arguments over the issue through the years and prevailed in every one of them. YMMV.
