The purposes of the residential zone districts are as follows:
A. 
Low Density Residential (R-1) Zone District. Applied to traditional suburban neighborhoods, primarily consisting of detached single-family residences and uses compatible with single-family uses. This zone district can be applied throughout the City where low density residential uses are deemed appropriate. The R-1 Zone District is consistent with the Low Density Residential General Plan designation.
B. 
Small Lot Residential (R-2) Zone District. Provides areas similar to the R-1 Zone District but also allows for smaller single-family lots and duplexes. It also allows uses compatible with these residential uses. This zone district is primarily utilized around and within areas designated by the General Plan as a Neighborhood Center or Civic Centers. The R-2 Zone District is also consistent with the Small Lot Residential General Plan designation.
C. 
Medium Density Residential (R-3) Zone District. Allows higher density single-family residential development, duplexes, attached townhouses and garden apartments. This zone district is primarily located within areas designated by the General Plan as a Neighborhood Center or Civic Center. The R-3 Zone District is also consistent with the Medium Density Residential General Plan designation.
D. 
Multiple-Family Residential (R-4) Zone District. Provides for the highest density residential uses with a level of standards conducive to providing a suitable living environment to those living in multiple-family residences, as well as uses compatible with multiple-family neighborhoods. This zone district is primarily located within areas designated by the General Plan as a Neighborhood Center or Civic Center. The R-4 Zone District is also consistent with the High Density Residential General Plan designation.
(Ord. 526 § 1, 2010)
Table 17.02.020 identifies the uses of land allowed by each of the residential zone districts. The last column of the table identifies a section of this title that references additional land use regulations or development standards that are applicable to that use. The applicable permit requirements for each use are established by the letter designations as follows:
Legend
"P"

"ZC"
Designates that a zoning clearance is needed, which is a ministerial staff review, pursuant to Section 17.35.020.
"U"
Designates that a use permit is required, pursuant to Section 17.35.030.
