1. 
In addition to the general purposes listed in Section 13-5.100, the specific purposes of the residential districts are to:
A. 
Reserve appropriately located areas for family living at a reasonable range of population densities consistent with the General Plan and sound standards of public health and safety.
B. 
Ensure adequate light, air, privacy, and yard/open space for each dwelling unit and protect residents from public safety hazards and other harmful environmental effects.
C. 
Preserve as many of the desirable characteristics of single-family residential districts as possible while allowing for associated residential uses such as daycare, rooming and boarding, home occupations, second residential units to the extent that substantial adverse impacts are not caused to adjacent residences.
D. 
Promote safe and well-designed neighborhoods and encourage new residential development to have an internal circulation system, including pedestrian walkways, bikeways, and access to transit facilities. Ensure provision of public services and facilities to support existing and planned residential densities.
E. 
Reserve appropriate areas for multifamily dwellings that may be located and designed to be compatible with adjacent land uses and residences.
F. 
Encourage development of innovative types of housing, including cohousing, congregate care facilities, and other types of housing that may provide low-cost alternatives to typical market-rate housing.
G. 
Encourage provision of affordable housing units, especially for single persons, single parents, elderly and young families. Provide well-designed, well-built housing units for low- and moderate-income households in mixed-density developments, including planned developments (PDs), avoiding a concentration in any limited area.
H. 
Provide additional affordable senior citizen housing. Encourage provision of senior housing by considering density bonuses where senior projects are desirable and compatible with special senior needs.
I. 
Allow for public and quasi-public land uses to complement residential development within close access such as schools, churches and daycare facilities; provided, that substantial adverse impacts such as traffic congestion, increased noise (ambient or episodic) or full use of available on-street parking, or other similar impacts are not caused on nearby residences.
2. 
The additional purposes of each residential zoning district are:
A. 
RS-E Residential Single-Family Estate. To provide sites for estate homes on larger lots to be developed with custom built and individually designed homes with a gross density of 1 or 2 units per acre and a minimum parcel size of 0.5 acre. Specific densities are assigned on the Zoning Map.
B. 
RS-L Residential Single-Family Low Density. To provide areas for single-family housing on smaller lots that will generally be developed as part of a larger planned subdivision where a limited number of models of varied exterior designs are built in a random pattern on individual lots with a gross density of 2 to 7 units per acre and a minimum parcel size of 6,000 square feet unless a smaller lot size is allowed by an approved planned development (PD).
C. 
RM-L Residential Multifamily Low Density. To provide sites for low-density multifamily housing such as townhouses, condominiums and apartments, and medium-density single-family housing that incorporate good design and amenities with a gross density up to 12 units per acre (midrange density of 9 units per acre). The minimum parcel size for multifamily housing is 3 acres. The minimum lot size for single-family housing is 4,000 square feet unless a smaller lot size is allowed by an approved planned development (PD).
D. 
RM-M Residential Multifamily Medium Density. To provide sites for medium-density multifamily housing such as townhouses, condominiums and apartments that incorporate good design and amenities with a gross density of 12 to 30 units per acre (midrange density of 20 units per acre) and a minimum parcel size of 5 acres.
E. 
RM-H Residential Multifamily High Density. To provide sites for high-density multifamily housing, typically located near public transit centers, adequate streets, shopping centers or other high-activity areas and that incorporate good design and amenities with a gross density of 30 to 55 units per acre (midrange density of 42 units per acre) and a minimum parcel size of 15 acres.

The standard performance standards for development specified in Chapter 13-31 shall be met. In addition, the following specific performance standards shall be met:

5. 
Upon reinstitution of the inclusionary housing ordinance, new residential development shall include a minimum 10 percent of the total number of units for affordable housing. No in-lieu fees will be accepted by the City unless the developer can establish extraordinary circumstances for not providing affordable housing or unless an agreement predating the adoption of the 1996 General Plan Amendment provides otherwise.
A density bonus may be provided, along with the waiver of fees and the relaxation of development standards, in exchange for low income or senior housing provided, as per Section 65915 of the California Government Code, as may be amended

(ZO § 6.300; Ord. 484 § 13, 2015; Ord. 515 § 2, 2018; Ord. 543 § 3, 2023; Ord. 544 § 3, 2023; Ord. 551 § 2, 2024)
All new and expanded development and uses that are allowed in the residential zoning districts are identified in Table 13-6.1.
