Each building shall then comply with the provisions of this code applicable to the use of that building. For the purpose of figuring the total area of a building to determine if an approved fire suppression system is required, fire walls and separation walls will not be considered in establishing separate buildings or fire areas.

Areas of the building not provided with surrounding walls shall be included in the building area if such areas are included within the horizontal projection of the roof or floor above. For the purpose of figuring the total area of a building in determining if an approved fire suppression system is required, fire walls and separation walls will not be considered in establishing separate building or fire areas.
EXCEPTIONS:
1. Multi-family buildings, Use Group R-2, for fire suppression systems only.
2. Single-family dwellings, Use Group R-3.
904.1.1 TOTAL AREA: For purpose of calculating total square feet (area), the total floor area includes mezzanines and basements contained within the surrounding exterior walls of the building on all floors and levels which are added together. The area included within the surrounding exterior walls of a building including canopies, when in the opinion of the code official the canopy creates or may create a hazardous situation, and all enclosed extensions are also added to the calculation. Areas of a building not provided with surrounding walls shall be included within the building area if such areas are included within the horizontal projection of the roof or floor above. Interior walls, including fire walls, and horizontal fire walls (floors), fire separation walls and party wall, shall not be considered as walls which divide a structure into two or more separate buildings, but a structure containing such interior walls shall be considered as one building for the purpose of this section.
EXCEPTION: Fire walls may be utilized to divide a structure of Use Group R-2 into more than one (1) building. The total area then shall be calculated between fire walls for compliance to this chapter.
