22.22.100 Purpose.

The RS zones are intended to provide the best possible locations and development standards for single-family dwellings; assure adequate access to schools, parks, and other community service facilities; prohibit negative impacts from adjacent nonresidential uses; protect the residential character of each neighborhood; and otherwise encourage high quality architectural design, an excellent environment for family life and the preservation of residential property values. As used in this chapter, “RS single-family residential zones” means the RS-5000 zone and the RS-6500 zone. (Ord. 708 § 1, 1992: Ord. 344 § 5 (part), 1972)

22.22.200 Location.

RS zones shall be located in areas that provide adequate pedestrian access to elementary schools and are convenient to intermediate schools, secondary schools, shopping centers, and other neighborhood facilities. RS zones shall be located in areas of sufficient size both to promote viable neighborhood interaction and identity and to continually maintain a high quality residential environment despite any adjacent nonresidential uses. (Ord. 344 § 5 (part), 1972)

22.22.300 Permitted uses.

Premises in the RS zone may be used for the following permitted uses: One single-farnily dwelling unit per legally constituted lot. “Single-family dwelling unit” shall also include manufactured housing as provided in Section 22.22.700(20), manufactured and certified under the National Mobile Home Construction and Safety Standards Act of 1974 subject to a precise plan for development. “Single-family dwelling unit” shall not include second units as provided for in Section 65852.1 et seq. of the California Government Code. Nothing in this section shall be construed to permit mobile home parks in the RS zone. Garages and on-site vehicle storage areas shall not be used for the storage of goods and materials not associated with residential uses or a permitted home occupation. The use of garages and approved on-site vehicle storage areas for storage of goods and materials shall not be a basis for the issuance of a residential on-street parking permit.

The precise plan shall be accompanied by elevations in sufficient detail to indicate the architectural features of all proposed dwelling types. Approval of a precise plan shall be conditioned, in part, upon approval of architectural quality and compatibility. If, upon review of elevations and other drawings, the planning commission or the city council determines that there is a question of architectural quality or compatibility, the planning commission or city council may elect to submit the precise plan to a design review committee composed of professionals in the fields of architecture, planning, and landscape architecture, such persons to be selected by the city council. A decision rendered by a design review committee shall be advisory to the planning commission and/or city council and shall in no way preempt their authority to make a determination regarding architectural quality or compatibility.

If the applicant contemplates the construction of single family dwellings in increments, he shall submit a proposed construction schedule designating the dwelling types to be constructed in each increment.

At the time the precise plan is considered, the planning commission may authorize minor variations to the development standards set forth herein in those instances where the modifications provide for more desirable development in keeping with the spirit and intent of this code.

After a precise plan has been approved by the planning commission, the director of community development may approve minor changes to the precise plan provided that, in his judgment and opinion, such changes do not substantively vary the previously approved precise plan and that these changes conform with the spirit and intent of this code. Any persons aggrieved by a decision of the director of community development may appeal the decision as provided in Chapter 20.95 of this code. (Ord. 770 § 1 (part), 1996; Ord. 344 § 5 (part), 1972)
