Part II — BASE DISTRICT REGULATIONS

Article 10 — Automobile Sales/Service and Custom Manufacturing District (AS-CM)

Walnut Creek Zoning Code · 2026-06 edition · updated 2026-07-07 · Walnut Creek

10-2.2.1001 Purpose and Intent.

The purpose of the automobile sales/service and custom manufacturing zone is to retain and promote a welldefined automobile sales and service area, which also allows custom manufacturing uses in the North Downtown Specific Plan area. The intent is to provide a distinct commercial district which reserves land area primarily for auto dealers, auto service, other related auto-oriented retail uses, and custom manufacturing.

The automobile sales/service and custom manufacturing zone is designed for the area just north of Ygnacio Valley Road where many auto dealerships and automobile service businesses currently exist. Automobile dealerships are advocated as the primary use. Auto services and auto-oriented retail uses which promote the vitality and expansion of automobile dealerships are also encouraged. Custom manufacturing uses are allowed within the North Downtown Specific Plan area, and are encouraged along Makers' Row on Pine Street. Other uses may be accessory to the above uses or which can demonstrate no adverse effects on the viability of the area may also be considered. (§10, Ord. 2200, eff. 12/6/19)
