Depending on whether a building is residential or commercial, a single story’s height can differ. Residential buildings often have one storey that is 10 feet tall, while commercial buildings typically have one level that is 12 feet tall.
A building may have some stories that are taller than others. In a commercial building, ground-floor floors can be up to 25 feet tall, although they are often only 15 feet tall in residential or hotel structures. Mechanical floors, which may be about 25 feet for commercial structures and 15 feet for residential dwellings if the building is quite tall, may be present.
