#	Multi/Split	A split-level home (also called a tri-level home) is a style of house in which the floor levels are staggered so that the “main” level of the house (e.g., the level that usually contains the front entry) is partway between the upper and lower floors.
#	One	The property being sold has one level. A discreet horizontal plane of interior living space (excluding basements).
#	One and One Half	A 1.5-story house is where the height of any of the walls on the second floor are less than the height of the walls on the first floor. First floor walls that extend up to the second floor level are not included in the height comparison. Depending on your state, province or other local regulations, there may be a specific height difference required. For example, some areas require that second floor walls should be less than 70% the height of first floor walls in order to be called a 1.5-story structure. Other areas are 50%, and it is clear that this may vary substantially from region to region. Another common trait is angled ceilings that compensate for the short walls making all but the edges of the room high enough for normal use.
