SEC. 210.2. C-3 DISTRICTS: DOWNTOWN COMMERCIAL.

   Downtown San Francisco, a center for City, regional, national, and international commerce, is composed of five separate districts, as follows:

   C-3-O District: Downtown Office. This District, playing a leading national role in finance, corporate headquarters and service industries, and serving as an employment center for the region, consists primarily of high-quality office development. The intensity of building development is the greatest in the City, resulting in a notable skyline symbolizing the area's strength and vitality. The District is served by City and regional transit reaching its central portions and by automobile parking at peripheral locations. Intensity and compactness permit face-to-face business contacts to be made conveniently by travel on foot. Office development is supported by some related retail and service uses within the area, with inappropriate uses excluded in order to conserve the supply of land in the core and its expansion areas for further development of major office buildings.

   C-3-O(SD) District: Downtown Office Special Development. This area south of Market Street and east of 3rd Street comprises the southern side of the core central business district, and is similar to and generally indistinguishable from the C-3-O District in terms of uses and character. The area is centered on the Transbay Transit Center. This District permits densities that exceed those in the C-3-O District and contains the tallest height limits in the City, reflecting its unparalleled public transportation access and geographically central position in the downtown.

   C-3-R District: Downtown Retail. This District is a regional center for comparison shopper retailing and direct consumer services. It covers a compact area with a distinctive urban character, consists of uses with cumulative customer attraction and compatibility, and is easily traversed by foot. Like the adjacent Downtown Office District, this District is well-served by City and regional transit, with automobile parking best located at its periphery. Within the District, continuity of retail and consumer service uses is emphasized, with encouragement of pedestrian interest and amenities and minimization of conflicts between shoppers and motor vehicles. A further merging of this District with adjacent, related Districts is anticipated, partially through development of buildings which combine retailing with other functions.

   C-3-G District: Downtown General Commercial. This District covers the western portions of downtown and is composed of a variety of uses: Retail, offices, hotels, entertainment, clubs and institutions, and high-density residential. Many of these uses have a Citywide or regional function, although the intensity of development is lower here than in the downtown core area. As in the case of other downtown districts, no off-street parking is required for individual commercial buildings. In the vicinity of Market Street, the configuration of this District reflects easy accessibility by rapid transit.

   C-3-S District: Downtown Support. This District encompasses Yerba Buena Gardens, which includes San Francisco's Convention Center, hotels, museums and cultural facilities, housing, retail, and offices arranged around public gardens and plazas. The District continues to accommodate important supporting functions such as wholesaling, printing, building services, and secondary office space. It also contains unique housing resources. The District is within walking distance of rapid transit on Market Street, and is served by transit lines on Third, Fourth, Mission and Folsom streets.

*    Not listed below.

(1)   C required if at or below the ground floor.

(2)   NP if located on floors one and two and does not offer on-site services to the general public. C required if located on the third floor, or floors four through six and the use is larger than 5,000 gross square feet in size.

   For uses located on the third floor, in addition to the criteria set forth in Section 303, a Conditional Use Authorization pursuant to this note shall be given only if the Commission determines that: the proposed use would not require modification of the location that would negatively impact existing architectural, historic and aesthetic features, or otherwise inhibit the conversion back to a principally-permitted use in the future; the proposed use would not have an actual or potential adverse impact on adjacent zoning districts in which non-retail sales and services uses are not permitted; and the proposed use will not result in the development of non-retail sales and services uses such that the District’s primary function is no longer an area for comparison shopper retailing and direct consumer services. Provided further that for any Conditional Use Authorization given pursuant to the preceding sentence, the Planning Commission also consider the following: whether the proposed use would complement or support principally-permitted uses in the District, and whether the site of the proposed use is not conducive to any principally-permitted uses in the District by virtue of physical limitations, including but not limited to the size and orientation of the floor plate and the nature of independent access to the third floor

(3)   C required if operated on an open lot.

(4)   Required to be in an enclosed building, NP if operated on open lot.

(5)   C required if taller than 25 feet above roof, grade, or height limit depending on site or if within 1000 feet of an R District and includes a parabolic antenna with a diameter in excess of 3 meters or a composite diameter of antennae in excess of 6 meters. See definition in Section 102 for more information.

(6)   C required for Formula Retail on properties in the C-3-G District with frontage on Market Street, between 6th Street and the intersection of Market Street, 12th Street, and Franklin Street.

(7)   Construction of Accessory Dwelling Units may be permitted pursuant to Sections 207(c)(4) and 207(c)(6).
