18.38.010 Purpose.

The purpose of this chapter is to establish residential zoning districts in the city, along with allowed use and development standards applicable to those districts. These districts are consistent with and implement the city’s general plan residential land use categories (estate residential, low density residential, downtown residential, medium density residential, and high density residential). (Ord. 738 § 1 (Exh. A) (part), 2013).

18.38.020 Characteristics of the residential districts.

The following descriptions of each residential zoning district identify the characteristic uses, intensity of uses, and level of development intended for that district.

A.    Estate Residential (ER) Zoning District. This district is applied to areas of the city where development is limited to very low density concentrations of single-family dwellings. The zone implements the general plan’s estate residential land use designation by allowing residential developments at an intensity of at or less than 1.0 dwelling units per gross acre. The ER district is intended to stabilize and protect the low-intensity residential characteristics of the district, to promote and encourage a suitable environment for family life, and to provide for detached single-family dwellings and the services appurtenant thereto.

B.    Low Density Residential (LR) Zoning District. This district is applied to areas of the city where development is limited to low density concentrations of single-family dwellings. The zone implements the general plan’s low density residential land use designation by allowing residential developments between 1.1 and 5.0 dwelling units per gross acre. The LR district is intended to stabilize and protect the residential characteristics of the district, to promote and encourage a suitable environment for family life, and to provide for detached single-family dwellings and the services appurtenant thereto. This district includes two variations: low density residential, narrow (LR-n) has the standard side yard setbacks of five feet, zero inches, and low density residential, wide (LR-w) which has a minimum building separation of fifteen feet, zero inches. The latter district is intended to require increased separation between single-family homes.

C.    Downtown Residential (DR) Zoning District. The district implements the general plan’s downtown residential land use designation by allowing for residential development between 3.1 and 10.0 dwelling units per gross acre. The DR district is intended to stabilize and protect the residential characteristics of the district, to promote and encourage a suitable residential environment, and to provide for single-family detached and attached homes, duplexes, secondary residential units, and the services appurtenant thereto.

D.    Medium Density Residential (MR) Zoning District. This district designates property for the development of a wide range of housing types with a density range between 5.1 and 12.0 dwelling units per gross acre. The zone implements the general plan’s medium density residential land use designation and is intended for higher-density single-family homes (attached or detached), condominiums, and small apartment complexes. This district provides a compatible transition between the lower-density residential neighborhoods of the city and the commercial centers.

E.    High Density Residential (HR) Zoning District. This district designates property for the development of residential uses with a density between 12.1 and 20.0 dwelling units per gross acre. The zone implements the general plan’s high density residential land use designation and is intended for higher-density residential development, such as apartments, condominiums, lofts, and other multi-story residential uses. This district is typically located along major roadways and transit corridors near and adjacent to or within service and employment centers. High-density residential development is designed to be pedestrian- and transit-friendly. (Ord. 767 (part), 2014; Ord. 738 § 1 (Exh. A) (part), 2013).

18.38.030 Allowed land uses and permit requirements.

Table 18.38.030-1 below identifies allowed uses and corresponding permit requirements for the residential zoning districts subject to compliance with Chapter 18.34 (Land Use Classification) and all other provisions of this title. Descriptions/definitions of the land uses can be found in Division V (Definitions). The special use regulations column in the table identifies the specific chapter or section where additional regulations for that use type are located within this title.

Use regulations in the table are shown with representative symbol by use classification listing: “P” symbolizes uses allowed by right, “CUP” symbolizes uses that require approval of a conditional use permit, and “N” symbolizes uses that are not permitted.

3.    Active living space (bedrooms, living rooms, dining areas, porches, etc.) may be set back a minimum of fifteen feet. Garages shall be set back a minimum of twenty feet.

4.    For uses requiring a conditional use permit, the planning commission may establish alternative minimum lot sizes.

5.    Minimum lot size requirements for single-family units in this district shall be three thousand five hundred square feet. Minimum lot dimensions shall be the same as the minimum dimensions in the LR-n district.

6.    Only permitted on corner lots.

7.    See Sections 18.60.030 and 18.60.040 for permitted projections into setbacks and exceptions to height limitations. A height increase may also be granted to allow for exceptional architecture or for unique architectural features (e.g., clock tower, church steeple, etc.) through the adjustment process (Section 18.16.110 (Minor adjustment)).

8.    The anti-monotony provisions in Section 18.38.050(B) apply to all lots smaller than ten thousand square feet.

9.    Only applies to single-family residential structures. This is the maximum ground floor footprint for the primary residential structure (including attached garages) and does not include accessory structures.

(Ord. 848, 2020; Ord. 738 § 1 (Exh. A) (part), 2013).

18.38.050 Anti-monotony provisions.

A.    Applicability. The following provisions apply to all residential lots smaller than ten thousand square feet in size. These are considered minimum standards and additional requirements may by applied during the residential design review process.

B.    Provisions:
