Full Breakdown

Sunnyvale Municipal Code Title 16 adopts the California Building, Plumbing, Electrical, and Mechanical Codes with local amendments. A building permit is required for all in-ground swimming pools and spas regardless of size. Above-ground pools exceeding 18 inches in depth or 5000 gallons require a permit. Permits include plan review for structural design, pool shell, plumbing, bonding and grounding of electrical equipment, and drainage. Separate electrical and plumbing permits are typically issued with the building permit. A final inspection and certificate are required before use. Spas and hot tubs follow the same CBC rules as pools. Residential pool permit fees for a standard in-ground build typically range 800 to 2500 dollars depending on valuation.
