17.30.010 Purpose:

There are four (4) residential zoning district categories to implement the general plan residential land use designations as listed below: Residential estate zoning district (R-E) Single-family residential zoning district (R-L) Multiple-family residential zoning district (R-M) High density residential zoning district (R-H) General discussions of each residential zoning district are provided in section 17.30.020, "Characteristics Of The Districts", of this chapter. (Ord. 473 §3, 2007)

17.30.020 Characteristics Of The Districts:

The following descriptions of each zoning district identify the characteristic uses, intensity of uses, and level of development intended for that district. Refer to the development regulations for specific standards applicable to each residential district.

A.    Residential Estate (R-E): The residential estate zoning district designation is applied to areas of the city intended to accommodate very low density single-family residential uses in a semirural setting. The district implements the residential estate general plan land use designation. Residential densities shall be within the range of 1.0 to 2.0 dwelling units per acre with a minimum parcel size of fifteen thousand (15,000) square feet. Property with this designation should serve as a transitional residential district between open space or agricultural uses and standard single-family neighborhoods.

B.    Single-Family Residential (R-L): The single-family residential zoning district designations are applied to areas of the city intended to accommodate low density single-family residential neighborhoods. Typical development includes detached (and in some cases attached) single-family homes. Permitted uses include single-family homes, second units, and compatible neighborhood support facilities. This district implements the single-family residential general plan land use designation with an allowed density range of 1.0 to 7.0 dwelling units per acre with a minimum parcel size of six thousand (6,000) square feet. Property with this designation should be located near other residential properties, schools, parks/open space, and neighborhood commercial services with low impact office and light industrial uses nearby. This district may include detached and attached housing types, as well as cluster developments. Building heights in this district are typically one and two (2) stories. Development standards allow for a variety of housing types.

C.    Multiple-Family Residential (R-M): The multiplefamily residential zoning district is intended to accommodate higher density single-family and lower density multi-family residential neighborhoods. This district accommodates a variety of housing types with a density range between 7.0 and 15.0 dwelling units per acre. Detached and attached single-family homes, duplexes, townhomes, condominiums, row houses, and garden apartments are permitted. Development standards for this district allow significant design flexibility to encourage a broad range of housing types and are intended to ensure compatibility and connectivity with surrounding neighborhoods and uses. Residential structures are typically one and two (2) stories in height (3 stories in some cases) with greater lot coverage than the low density single-family residential districts. The R-M district should serve as a transitional residential district between lower density single-family neighborhoods and high density residential districts, office buildings, commercial uses, or light industrial uses. R-M sites should be located near arterial or collector roads. This district implements the medium density residential general plan land use designation.

D.    High Density Infill (R-H): The high density residential zoning district is applied to areas of the city intended to accommodate higher density multi-family development such as apartments and condominiums. This designation may also include high density single-family development types such as townhomes and other attached housing types. High density detached homes may also be considered in the R-H district on a case by case basis with a conditional use permit request. This district implements the high density residential general plan land use designation. Residential densities shall be in the range of twelve (12) to twenty one (21) dwelling units per acre. Property with this designation should be located near other multi-family sites, office, commercial uses, or light industrial areas. Additionally, multi-family residential sites should be located along thoroughfare, arterial, or collector roads or near existing or planned public transit stops. Standards for these districts promote attractive residential development that is compatible with surrounding neighborhoods, while at the same time carefully regulating uses to assure compatible development that limit impacts on surrounding uses. Development is typically two (2) stories in height (3 stories in some cases) with greater lot coverage than the medium density residential districts. (Ord. 473 §3, 2007)

17.30.030 Allowed Uses And Permit Requirements:

Section 17.26.040, table 17.26-1 of this title identifies allowed uses for all residential zoning districts subject to compliance with chapter 17.26, "Allowable Land Uses", of this title and all other provisions of this title. Descriptions of many land use listings can be found in division VI, "Zoning Definitions", of this title. Note: The far right column, "Specific Use Regulations Of This Title", in the table includes the section number(s) for regulations that apply to the particular use listed, in addition to the other general standards of this title. (Ord. 473 §3, 2007)

17.30.040 Development Standards:

The development standards in this section have been divided into individual tables by primary residential zoning district categories as follows:

Table 17.30-1

Residential estate zoning district

Table 17.30-2

Single-family residential zoning district

Table 17.30-3

Multiple-family zoning districts

Table 17.30-4

High density infill zoning district

These standards, along with division IV of this title, are intended to assist property owners and project designers in understanding the city’s minimum requirements and expectations for high quality residential development. The designated approving authority will review development applications against these standards to determine compliance with applicable zoning regulations.
