Patterson Zoning Code · 2026-06 edition · updated 2026-07-25 · Patterson

§ 18.42.010. Purpose.

The purpose of this chapter is to establish commercial and office 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 commercial and medical/professional office land use categories as shown in Table 18.42.030-1. (Ord. 738 § 1 (Exh. A) (part), 2013)

§ 18.42.020. Characteristics of the commercial and medical/professional office districts.

The following descriptions of each commercial and medical/professional office zoning district identify the characteristic uses, intensity of uses, and level of development intended for that district.

  • A. Neighborhood Commercial (NC) Zoning District. The NC district is applied to areas where there is a high concentration of housing to support the neighborhood center concept in the city's general plan by providing commercial uses that serve daily needs (e.g., retail and personal services) within close proximity to residential uses. This zoning district encourages development that is pedestrian-oriented and is well connected to surrounding residential neighborhoods.

  • B. Highway Service Commercial (HSC) Zoning District. The HSC district is consistent with the highway service commercial land use designation in the general plan. This district is applied to locations along highways and is intended to provide businesses and services to meet the needs of the traveling public.

  • C. Downtown Core (DC) Zoning District. The DC district is consistent with the downtown core land use designation in the general plan. The purpose of the DC district is to stabilize, improve, and protect the characteristics of commercial businesses and to provide adequate locations for stores, shops, and offices which are supplying commodities or performing services for residents of the city as a whole. The DC district is intended to guide and regulate commercial development within the historic downtown area.

  • D. General Commercial (GC) Zoning District. The GC district is consistent with the general commercial land use category in the general plan. The purpose of the GC district is to stabilize, improve, and protect the characteristics of commercial businesses and to provide adequate locations for stores, shops, and offices which are supplying commodities or performing services for residents of the city as a whole. The GC district is intended to guide and regulate general commercial development.

  • E. Medical/Professional Office (MPO) Zoning District. The MPO district is consistent with the medical/professional office land use designation in the general plan. The purpose of the MPO district is to provide for concentrations of hospitals, medical facilities, auxiliary uses, and medical services and to encourage the orderly and harmonious development of these facilities, which are performing services for residents of the city as a whole. The MPO district is intended to guide and regulate medical, professional office, and similar and compatible development.

  • (Ord. 738 § 1 (Exh. A) (part), 2013)
