CHAPTER 17

26 R-3-C - MULTIPLE-DWELLING ZONE

17.26.010 Purpose.

   (A)   It is found that a substantial number and a heavy concentration of old, substandard and deteriorated buildings and structures used for human habitation as one-family dwellings, two-family dwellings and multiple dwellings are located on property within the boundaries of Grand Boulevard in the city and as delineated on the city’s Official Zoning Map. The public health, safety and welfare of the city require the replacement and alteration of the older, substandard and deteriorated buildings and structures. To fulfill the requirement, a multiple-dwelling zone (R-3-C) is created and the property development standards therefor are provided in §§ 17.26.060 through 17.26.180. The zone and standards are intended to encourage replacement and alteration of the older substandard and deteriorated buildings by providing incentives for land assemblage and a greater number of dwelling units per lot area than is allowed in other multiple-residential zones of the city (R-2, R-3 and R-G). The R-3-C zone shall be imposed only on that real property located within the boundaries of Grand Boulevard in the city, as said boulevard is delineated on the city’s Official Zoning Map.
   (B)   Except as specifically provided elsewhere in this title, any and every building, structure and land, or any portion thereof in the R-3-C zone, shall be used, occupied and/or erected, constructed, established, altered, enlarged, maintained and moved into exclusively and only in accordance with each and every provision of §§ 17.26.020 through 17.26.200 and any amendments thereto.
