SEC. 210.4. M DISTRICTS: INDUSTRIAL.

   M-1 Districts: Light Industrial. In general, the M-1 Districts are more suitable for smaller industries dependent upon truck transportation, while the M-2 Districts are more suitable for larger industries served by rail and water transportation and by large utility lines. In M-1 Districts, most industries are permitted, but some with particularly noxious characteristics are excluded. The permitted industries have certain requirements as to enclosure, screening, and minimum distance from Residential Districts.

   M-2 Districts: Heavy Industrial. These Districts are the least restricted as to use and are located at the eastern edge of the City, separated from residential and commercial areas. The heavier industries are permitted, with fewer requirements as to screening and enclosure than in M-1 Districts, but many of these uses are permitted only as conditional uses or at a considerable distance from Residential Districts. Most of the land zoned M-2 is controlled by the Port of San Francisco.
