In Central Ohio, it doesn't have to have a closet to be considered a bedroom. An example is some of the homes in the Historic Northwest District which were built before it became "popular" to have closets in the rooms.

However, many buyers expect a bedroom to have a closet. And their perception of what a room requires over rules what the "letter of the law" is in this case.

A room with a closet is considered a bedroom, and must meet egress requirements for fire safety reasons.

No, but any habitable area of a house to be considered a room must have some type of light, arifical or natural, also the room must have a natural type of venilation like a window

If you bought a house would you consider a room a bedroom if it did not have a closet? Most people would not. Most people would just see it as a room that could be used different ways.
If you add a closet is there any room left for a bed and other stuff? If not I can not imagine anyone thinking it was a bedroom. If there is add a closet before trying to sell. It will look like a bedroom then.

The definition varies based on locality. Call your local building inspector for more information.

In order for a room to be considered a bedroom you need to have a heat source(electric baseboard, FAU, hydronic), a closet, and depending on your local building codes you will need to have adequate ingress/egress, which most times is a window of a specific dimension. In some areas where a home has a septic system for waste removal the size of the system determines how many bedrooms a house can have. If you exceed the bedroom count for a septic system you can overload the system and it will not function properly or have a shorter life. Do not hesitate to contact your local building department to verify what your town/county requires to consider a room a bedroom. I hope this helps and if you need further explanation please contact me.
