Sunnyvale, CA Outdoor Cooking: Outdoor Kitchen Permits (2026)

Sunnyvale adopts the California Building Code, Plumbing Code, Electrical Code, and Mechanical Code by reference under SMC Title 16. Permanent outdoor kitchens require a building permit when they involve gas-line extensions (plumbing permit and licensed installer), 120V or 240V electrical wiring (electrical permit), water/drain plumbing (plumbing permit), or a roofed structure over 120 sq ft. Freestanding portable BBQ islands without permanent hookups do not require a permit. Gas-line installations must be performed by a licensed plumber, pressure-tested per California Plumbing Code Chapter 12, and inspected by Sunnyvale Building Inspection through the One Stop Permit Center. Outdoor kitchen structures count as accessory structures under Sunnyvale Title 19 (Zoning) Single Family Home regulations and must observe the underlying district's setbacks: typically 6 feet from side property line and 6 feet from rear in R-1 (Sunnyvale's most common district), with greater setbacks in R-0. Accessory structures over 120 sq ft and any structure with utilities require a permit; accessory structures under 120 sq ft without utilities are typically exempt under the California Building Code statewide standard. Covered outdoor kitchens or those attached to the primary dwelling may count toward Floor Area Ratio (FAR) and lot coverage limits in SMC Title 19. Title 24 energy compliance may apply to electrical and gas components.
