§ 14.04.01 DIMENSIONAL STANDARDS.

   A.   General dimensional standards. The following Tables 4.01-1 to 4.01-3 include the dimensional standards for residential, mixed-use, and special purpose zoning districts contained in Article II (Zoning Districts). Exceptions and encroachments to these standards are contained in § 14.04.01B. In case of conflict between the dimensions shown in this section and the dimensions shown for individual zoning districts in Article II, the provisions in this section shall apply. In each table, a blank cell indicates that there is no standard for that dimension or measurement.

[1]   Lot width times depth must equal or exceed minimum lot area. [2]   Garages, carports, or any structure used to park vehicles that face a front yard right-of-way must be set back a minimum of 25 feet. On a reverse corner lot, the front yard is defined by the shorter of the two street frontages, but a 25- foot garage setback is required from any “front” or “side” street right-of-way that the lot’s parking structure faces. [3]   A lot with an average depth of 100 feet or less may maintain a 20-foot front yard setback for a garage. [4]   A lot with an average width of 80 feet or less may have a side yard of 5 feet, or 10 feet if it is a corner lot. [5]   If a garage is to be accessed from a corner lot with a street side setback, the minimum setback for the garage shall be 20 feet, regardless of the minimum setback identified in this table. [6]   Detached accessory structures may be built within 5 feet of the side and rear property lines. [7]   Accessory buildings are limited to garages and must be located in the rear of the primary structure. Garages may not face the street. [8]   A property developed with one single-family or one two-family unit may use the R-3 building setback standards. [9]   See Section 14.02.03.H.4 for minimum building story requirements. [10]   See Section 14.02.03.I.4 for minimum building story requirements.
