Subject property is a contemporary with a strong sloping lot to the front. It has three total levels. The top two levels are above grade. The level in question is the lowest level. The front third section of the lowest level is all above grade and is the entry foyer to the upper two levels with the same grade of interior finish. The rear third section of the lowest level is totally below grade with a wine cellar and utility area. The middle third is open to the ground, no basement or crawl space, it is just open, with no connection between the front and rear sections of this level. See attached photos. It seems the utility of the home would call for the front 1/3 of the lowest level to be counted as GLA, with the back third of the lowest level being a partial basement. Would this comply with GLA standards, even though they are the same level, there is no connection between the two sections, and the front section is totally above grade with the rear section being totally underground?
