The purpose of this chapter is to establish residential districts in the City that provide appropriate locations for low density residential, medium density residential, and high density residential. These zones are consistent with and implement the City's General Plan land use designations, as shown in Table 17.25.020-1.
(Ord. 247, 1/15/2025)
A. 
Allowed Uses Table. Table 17.35.020-1 identifies allowed uses and corresponding approval requirements for the residential zones subject to compliance with all other provisions of this Title. Descriptions/definitions of many of the land uses can be found in Article VI, (Definitions), of this Title.
B. 
Approval Requirements.
1. 
Where indicated with a letter "P" the use shall be a permitted use by right, and subject to compliance with all applicable provisions of this Title.
2. 
Where indicated with a letter "C" the use shall be conditionally permitted subject to the approval of a conditional use permit, described in Chapter 17.80 (Conditional Use Permits).
3. 
Where indicated with a "—," the use is prohibited within the zone.
4. 
The Additional Requirements column in the table identifies additional use regulations for specific uses and/or the specific chapter or section where additional regulations for that use type are located within this Title, where applicable. Uses for which additional requirements are listed shall be allowed only upon satisfaction of the specified additional requirements. Under no circumstances shall Table 17.35.020-1 authorize a use without satisfaction of such specified additional requirements.
C. 
Unlisted Uses. The allowed use tables of this Title may not include all possible uses. When a specific use is not listed and it is unclear whether the use is permitted by right, permitted conditionally, or prohibited, the Community Development Director or designee appointed by the City Manager may make a determination, consistent with Chapter 17.100 (Similar Use Determination), that new uses not listed here that have substantially similar characteristics to specific listed permitted uses may be considered permitted as the similar use by right, or conditionally as appropriate.
D. 
Uses on Vacant Lots. A Minor or Major Development Review is required for approval when a permitted or conditionally permitted use is proposed for a vacant lot. A Minor or Major Development Review is not required for approval when a permitted or conditionally permitted use is proposed for an existing building.
