The purpose of this chapter is to implement the goals and objectives of the general plan toward the provision of a wide range of residential opportunities and dwelling unit types to meet the needs of present and future residents of the city of all socio-economic groups. This chapter establishes permitted uses and identifies processes necessary to evaluate certain uses to determine suitability within residential zoning districts.
(Ord. 2623-99 § 1)
Residential zoning districts are reserved for the maximum allowable density specified in this section, expressed in number of dwelling units per acre, except as allowed under Section 19.18.025 (Density bonus). Other uses will be permitted which are compatible with the residential character of the zoning districts.
(a) 
The R-0 and R-1 low-density residential zoning districts are zoning districts reserved for the construction, use and occupancy of not more than seven dwelling units per acre.
(b) 
The R-1.5 low medium density residential zoning district is reserved for the construction, use and occupancy of not more than ten dwelling units per acre.
(c) 
The R-1.7/PD low medium density residential zoning district provides for construction use and occupancy of small-lot, residential development of not more than fourteen units per acre. R-1.7 shall always be combined with a planned development combining zoning district as provided for in Chapter 19.26.
(d) 
The R-2 low medium density residential zoning district is reserved for the construction, use and occupancy of not more than twelve dwelling units per acre.
(e) 
The R-3 medium density residential zoning district is reserved for the construction, use and occupancy of not more than twenty-four dwelling units per acre.
(f) 
The R-4 high density residential zoning district is reserved for the construction, use and occupancy of not more than thirty-six dwelling units per acre.
(g) 
The R-5 high density residential and office zoning district is reserved for the construction, use and occupancy of not more than forty-five dwelling units per acre alone or in combination with hotels or motels.
(h) 
The R-MH residential-mobile home zoning district is reserved for the construction, use and occupancy of mobile homes and other uses incidental to the operation of such parks. Such parks may not contain more than twelve dwelling units per acre of mobile home park area.
(Prior zoning code §§ 19.32.010(a), 19.32.015(a), 19.32.017(a), 19.32.020(a), 19.32.030(a), 19.32.040(a), 19.32.050(a), 19.32.060(a); Ord. 2623-99 § 1; Ord. 2976-12 § 10)
A density bonus above the maximum allowable density of a residential zoning district may be granted under California Government Code Sections 65915 through 65918 and through other development incentives adopted by the city council. An application for a density bonus and any associated incentives, concessions, waivers of development standards, or modified parking ratios shall be submitted with the application for a discretionary permit for the development. The director of community development may establish guidelines, forms, and submittal requirements for the filing, processing, and consideration of density bonus applications.
(Ord. 2976-12 § 11; Ord. 3176-21 § 1)
(a) 
Use Table. Table 19.18.030 sets forth those uses which are permitted, conditionally permitted, and prohibited in residential zoning districts, and the type of approval a use requires.
(1) 
Permitted (P). A use shown with "P" in the table is allowed subject to compliance with all applicable provisions of this title. If the proposed use includes new construction, changes to the exterior of a building or other site modification, design review is required in accordance with the provisions of Chapter 19.80, Design Review.
(2) 
Miscellaneous Plan Permit (MPP). A use shown with "MPP" in the table requires the approval of a miscellaneous plan permit, in accordance with the provisions of Chapter 19.82, Miscellaneous Plan Permit. If there is an existing valid miscellaneous plan permit for the use, and no new construction or expansion is proposed, then such use may be conducted without requiring another miscellaneous plan permit.
(3) 
Use Permit and Special Development Permit (UP and SDP). A use shown with "UP" or "SDP" requires approval of a use permit or special development permit, in accordance with the provisions of Chapter 19.88, Use Permit, or Chapter 19.90, Special Development Permit, whichever applies. If there is an existing valid use permit or special development permit for the use, and no new construction or expansion is proposed, then such use may be conducted without requiring another use permit or special development permit.
(4) 
Prohibited (N). A use shown with "N" in the table is prohibited.
(5) 
By-right housing developments on sites identified in Chapter 19.73 require approval of a ministerial miscellaneous plan permit in accordance with the provisions of Chapter 19.82, even if a Use Permit or Special Development Permit is listed in Table 19.18.030.
(b) 
Compliance. It is a violation of this chapter to:
(1) 
Engage in a use that is conditional without complying with the imposed conditions;
(2) 
Engage in a prohibited use;
(3) 
Engage in a use requiring a miscellaneous plan permit, use permit or special development permit without obtaining the required permit.
