Thousand Oaks has 2 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.

Fencing & Safety Requirements

All residential swimming pools and spas in Thousand Oaks must have safety barriers meeting California Building Code requirements. Fences must be at least 60 inches tall with self-closing, self-latching gates. Barriers must prevent unsupervised access by children under five.

Key details: Minimum Height: 60 inches. Gate Latch: Self-closing, self-latching at 54 in.. Opening Size: No larger than 4-inch sphere. Code: CBC Section 3109, CA H&S 115920.

Failure to maintain pool barriers is a building code violation. Ventura County Environmental Health may also cite non-compliant pools. Fines range from $100 to $500, and pool use may be restricted until barriers meet code.

Pool Permits
