Full Breakdown
Hesperia Municipal Code § 15.04.050 defines a "swimming pool" as any structure holding water over 18 inches deep, sweeping in hot tubs, spas, and portable or fixed wading pools along with in-ground and above-ground pools. Once that depth threshold is met, the pool or spa must be enclosed by a barrier at least 60 inches tall, built to the gate and construction standards of California Building Code § 3109 and the International Swimming Pool and Spa Code. It doesn't matter whether the unit is called a "pool" or a "hot tub": depth is what triggers the requirement, not the label.
Violations & Fines
Building without the required 60-inch barrier is a building code violation; the Building Official can withhold final inspection, issue a correction notice, or red-tag the installation until it's compliant.
