A. 
The purpose of the residential zones is to provide for areas of residential development at various specified densities throughout the City. The residential zones are intended to accommodate a variety of housing types and to encourage the provision of housing. The purpose and applicability of each residential zone identified in Table 18.10.010.A (Zones, Overlays Zones, and Specific Plans) are as follows:
1. 
Single-Family Residential Estate (R-E) Zone. The intent and purpose of the R-E zone is to designate areas within the City that may best facilitate the development and use of single-family homes on large parcels, where a rural character and atmosphere can be maintained and preserved in an urban setting.
2. 
Single-Family Residential (S-F) Zone. The intent and purpose of the S-F zone is to designate certain residential areas within the City that may best facilitate the development of single-family homes and other compatible uses in a low-density residential neighborhood setting, where development characteristics promote neighborhood quality and livability. Compatible uses may include recreational, religious, and educational facilities, when deemed to be essential elements of a balanced neighborhood, while minimizing adverse impacts to adjacent properties.
3. 
Residential Infill (R-I) Zone. The intent and purpose of the R-I zone is to designate certain residential areas within the City that may best facilitate smaller-sized, low-density residential developments that accommodate attached and detached residential dwelling types and allow for sufficient design flexibility in order to utilize unique physical land characteristics such as size, shape, and configuration while preserving the nature of single-family neighborhoods.
4. 
Multiple-Family Residential, Medium Density (R-M-M) Zone. The intent and purpose of the R-M-M zone is to designate certain areas within the City that may best facilitate the development of medium-density residential housing types such as multifamily residential housing, including detached and attached dwellings, apartment complexes, and other compatible uses of land that can serve as a transition between more intense residential uses of land and single-family residential neighborhoods. The R-M-M zone can provide compatible development along principal streets and highways, and in transitional areas can provide for developments and uses of land closely related to multifamily residential characteristics best suited to carry out the needs of the community. Other compatible uses of land may include public, semipublic, institutional, and other transitional land uses which may contribute to a variety of community needs and may not necessarily be compatible with solely residential or limited commercial uses.
5. 
Multiple-Family Residential, High Density (R-M-H) Zone. The intent and purpose of the R-M-H zone is to designate certain areas in the City that may best accommodate high-density residential housing types, such as townhouses, condominiums, and apartments primarily along major street corridors, near major activity centers, and adjacent to large-scale commercial developments to act as a transitional zone.
6. 
Planned Residential Unit Development (PUD) Zone.
a. 
Purpose. The intent and purpose of the PUD zone is to principally designate and distinguish certain areas within the City that can best be utilized to attain the following:
i. 
To create a better living environment;
ii. 
To promote the achievement of residential land use amenities that could not otherwise be obtained under more conventional methods and development;
iii. 
To achieve greater design flexibility of residential acreage than could otherwise be possible through the application of more conventional residential zone regulations;
iv. 
To encourage well-planned developments through more creative, innovative, and imaginative planning principles, practices, and techniques;
v. 
To reserve a greater proportion of open space land for recreation, conservation, park, and other similar kinds of use facilities than is otherwise required by more conventional residential zone regulations;
vi. 
To provide for a more efficient, appropriate, and desirable use of land which is sufficiently unique in its physical characteristics and other circumstances to warrant special methods of development;
vii. 
To provide areas of natural scenic beauty, vistas, landmarks, promontories, and other environmental features through integrated land planning, design, and unified control of physical development patterns; and
viii. 
To set forth use regulations and property development regulations that will best assure that the intent and purpose of this Chapter are carried out.
b. 
The PUD zone is a land use classification which, in part, assists in the implementation of the residential land use, housing, and environmental elements of the General Plan. It is a zone classification designed to be applied on selective areas of the community where the land is of sufficient size, shape, and configuration, and possesses the characteristics to warrant a planned residential unit development. The development of property herein shall be determined by and subject to a Conditional Use Permit in accordance with Section 18.05.030 (Conditional Use Permits).
(Ord. 1201, 12/9/2025)
Table 18.11.020.A (Allowed Uses and Regulations in Residential Zones) establishes the uses allowed in each residential zone and the land use permit required to establish each use. Section numbers in the right-hand column refer to other sections of this Title. Uses of land and development which are not specifically permitted are hereby expressly prohibited. In cases where a specific land use or activity is not defined, the Zoning Administrator shall assign the land use or activity to a classification that is substantially similar in character as provided in Section 18.01.050 (Interpretation of Regulations).
