In general, use Main Level, Upper Level, and Lower Level, not first floor, second floor, etc. Occasionally, a plan may require special nomenclature. For example, a third level might be a Crow’s Nest or Cupola. Or, a beach house might have a Bedroom Level on what is usually the main level, and its central living area or Main Level would be on the upper level. In this case, use Bedroom
Level and Main Level for clarity. There may be other exceptions to improve clarity.
When counting bedrooms on a floor plan, follow the first reference in classifying the space. For example, if it’s a bedroom/study, count it as a bedroom. If it’s a den/bedroom, don’t.
Count a bath with a shower but no tub as a full bath.
