This chapter establishes zoning districts and overlay districts in order to separate incompatible land uses from each other by:
(a) 
Providing different zoning districts for agricultural, residential, commercial, industrial, recreation and public uses;
(b) 
Establishing the approval procedure necessary to establish certain land uses in various zoning districts; and
(c) 
Delineating between various uses for the purpose of regulating the location, height, bulk, number of stories and size of buildings and structures; and, the use of lots, setbacks and open spaces; and, the inten-sity of land uses.
In so doing, it is intended to implement the General Plan adopted pursuant to Government Code Section 65300 et seq.
(Ord. 602 § 2, 2016)

(Ord. 602 § 2, 2016)
Overlay districts intended to protect public safety and the environment and to preserve scenic, cultural and historic resources are established as follows:
(a) 
Overlay districts:
(1) 
Flood Hazard—FH;
(2) 
Geologic Hazard—GH;
(3) 
Historic Site—HS;
(4) 
Sensitive Resource—SR;
(5) 
Planned Development—PD;
(6) 
Emergency Shelters (ES) (9-3.501).
(Ord. 602 § 2, 2016)
(a) 
Zoning Districts. The letter symbols listed after each zoning district in Section 9-3.102(a) through (c) shall be used to designate the location of various zoning districts on the official zoning maps (Section 9-1.102).
(b) 
Overlay Districts. The letter symbols listed after each overlay district in Section 9-3.103(a) shall be appended to the base zoning district and be placed in parentheses thereafter to designate the location of various overlay districts on the official zoning maps (Section 9-1.102). Example: Residential Suburban as the base zone within a Flood Hazard and Geologic Hazard overlay area would show on the official zoning maps as RS (FH) (GH).
(c) 
Density in Residential Multiple-Family Zoning District. A number specifying the maximum permitted number of dwelling units per net acre in multiple-family residential zoning districts shall be appended to the base zoning district to designate the density on the official zoning maps (Section 9-1.102).
Example: Residential multiple-family allowing 24 units per net acre within a Historic Site overlay area would show on the official zoning maps as RMF-24 (HS).
(d) 
Minimum Lot Size in Residential and Agricultural Zoning District Areas. A symbol specifying the minimum lot size in acres in certain residential zoning districts shall be appended to the base zoning district and be placed following a hyphen thereafter where necessary to designate the minimum lot size on the official zoning maps (see Section 9-1.102).
Example: Residential Single-Family with a 1/2 acre minimum lot size in a Flood Hazard Overlay Zone would show on the official zoning maps as RSF-X(FH). Minimum lot size will not always be shown on the official maps especially in zoning districts where the minimum size is uniform, in circumstances where Chapter 9-6 establishes minimum sizes for some, but not all, uses within a zoning district, and where performance standards identified for certain zoning districts in this chapter are used to establish the minimum lot size.
(Ord. 602 § 2, 2016; Ord. 614 § 4, 2017)
In all zone districts, the off-site sale of new and used automobiles and trucks is unlawful. New and used automobile and truck sales must be conducted only at the permanent property address in the City of Atascadero listed for the dealership on its Department of Motor Vehicle dealer's license.
(Ord. 602 § 2, 2016)
