A building designed or used for two or more occupancies, representing different occupancy classifications, except in the case of auxiliary uses as described in Section 13-56-250, shall be classified as a mixed occupancy.
(Prior code § 48-12)
Rooms and spaces normally provided and incidental to the principal use of a building and under the same management and control shall be classified as auxiliary uses and shall not be considered as constituting a mixed occupancy.
Auxiliary uses shall not introduce any unusual hazard or danger unless in the judgment of the building commissioner such auxiliary use is indispensable to the principal use.
Auxiliary uses, other than legal home occupations licensed under Section 4-6-270, shall be limited to a maximum of five percent of the area occupied by the principal use, provided however, that the building commissioner and the fire commissioner may jointly approve auxiliary uses exceeding said five percent of the area of the principal use when in their opinion such auxiliary uses do not unduly increase the hazards. A legal home occupation licensed in accordance with Section 4-6-270 shall not permanently occupy more than ten percent of the floor area of any single-family residence or 15 percent of the floor area of any unit in a multiple dwelling building; provided, however, that in no instance may one or more home occupations in any single dwelling unit permanently occupy more than 300 square feet of the dwelling unit.
Loading spaces and appurtenant driveways extending more than five feet into a building or structure when used by vehicles with internal combustion engines on any street level floor within industrial units and storage units one story in height, shall be limited to 20 percent of the floor area of the principal use, and shall be separated from the principal use by a loading platform, curb, railing or other fixed barricade. The vehicles with internal combustion engines using such loading spaces and appurtenant driveways shall not remain inside the building for a longer period than necessary for loading or unloading and while inside the building shall at all times be under control of the driver.
Spaces classified as auxiliary uses shall comply with the applicable requirements of this Code pertaining to the specific use but not require the special separations as established in Section 13-56-280 and shall not govern height or area limitations as established for the principal occupancy of the building.
(Prior code § 48-12.2; Amend Coun. J. 9-13-89, p. 4604; Amend Coun. J. 4-1-98, p. 65910 § 6; Amend Coun. J. 3-5-03, p. 104990, § 21; Amend Coun. J. 11-13-07, p. 14999, Art. II, § 1; Amend Coun. J. 5-9-12, p. 27485, § 174)
