The following minimum and maximum floor area restrictions shall apply to buildings in the Hillside Area of the City:
A. Minimum Restrictions: Any building that serves as the primary residential building on a site area shall have a minimum floor area of one thousand six hundred (1,600) square feet and shall have a minimum width, at its widest point, of twenty feet (20').
B. Maximum Restrictions: The standards set forth in this subsection shall govern the maximum cumulative floor area that may be developed on any site within the Hillside Area.
Notwithstanding any other provision of this section, an owner of a site within the Hillside Area may develop buildings or structures on that site which cumulatively contain up to four thousand five hundred (4,500) square feet of floor area even if the application of the standards set forth in this section would not permit that amount of development.
In addition, notwithstanding any other provision of this section, the cumulative floor area developed on any one site area, in combination with the floor area of all basements constructed on that site, shall not exceed fifteen thousand (15,000) square feet unless permitted by a Hillside R-1 permit issued pursuant to article 25.5 of this chapter. Provided, however, that up to one thousand six hundred (1,600) square feet of basement garage area and up to three hundred (300) square feet of basement mechanical area shall not be included within the calculation of the floor area of a basement for the purposes of this paragraph.
1. For site areas which have no level pad, or a level pad of less than seven hundred fifty (750) square feet in area, and the average slope of the site area is twenty percent (20%) or greater, then the maximum cumulative floor area for all buildings and structures shall be twenty percent (20%) of the site area.
2. For those sites not governed by subsection B1 of this section, the maximum permitted cumulative floor area of all buildings and structures shall be calculated as follows:
a. If the area of a site is fifteen thousand (15,000) square feet or less, then the maximum permitted cumulative floor area for buildings and structures on the site shall be forty percent (40%) of the area of the level pad plus ten percent (10%) of the area of the slope.
b. If the area of a site is between fifteen thousand one (15,001) and twenty five thousand (25,000) square feet, then the maximum permitted cumulative floor area for buildings and structures on the site shall be thirty seven percent (37%) of the area of the level pad plus ten percent (10%) of the area of the slope.
c. If the area of a site is between twenty five thousand one (25,001) and thirty thousand (30,000) square feet, then the maximum permitted cumulative floor area for buildings and structures on the site shall be thirty four percent (34%) of the area of the level pad plus ten percent (10%) of the area of the slope.
d. If the area of a site is greater than thirty thousand (30,000) square feet, then the maximum permitted cumulative floor area for buildings and structures on the site shall be thirty one percent (31%) of the area of the level pad plus ten percent (10%) of the area of the slope.
3. If the area of a site equals or exceeds two (2) acres, the maximum cumulative floor area may exceed the limitations set forth in subsections B1 and B2 of this section if permitted by a Hillside R-1 permit issued pursuant to article 25.5 of this chapter.
C. Additional Requirements: Notwithstanding any other ordinance or provision of this Code, a level pad area must contain a level square shaped area with minimum dimensions of twenty feet (20') per side for the level pad to be used to calculate the maximum permitted cumulative floor area of buildings and structures in the Hillside Area pursuant to subsection B of this section. "Level pad" shall have the meaning set forth in section 10-3-100 of this chapter.
Notwithstanding any other ordinance or provision of this Code, the maximum cumulative floor area of the portion of any buildings and structures located off the existing level pad of any lot in the Hillside Area of the City shall be one thousand (1,000) square feet, unless a Hillside R-1 permit is issued pursuant to subsection 10-3-2550K of this chapter. "Level pad" shall have the meaning set forth in section 10-3-100 of this chapter, and "existing level pad" shall mean the level pad in existence on the effective date hereof (September 30, 2016).
For the purposes of this section, the maximum cumulative permitted floor area shall be calculated based upon the finished grade of the site.
Further, if a portion of a site area is to be dedicated to the City for the purposes of establishing or enlarging a street or an alley, and such dedication is to be made in conjunction with a development approval, then, for the purposes of calculating the maximum permitted floor area for the proposed development pursuant to this section, the site area shall include that portion of the site area that is to be dedicated to the City. However, the dedicated area shall not be included in the calculation of floor area for subsequent development, including additions to the original development. (Ord. 18-O-2751, eff. 4-6-2018)
