Full Breakdown
Chapter 15.22 of the National City Municipal Code adopts the Uniform Swimming Pool, Spa and Hot Tub Code (2009 Edition) with local amendments, controlling within the city from January 1, 2011 under Ordinance No. 2010-2356. Section 15.22.030 amends Section 103.4.1 so that every applicant for a permit to install, remove, alter, repair or replace a swimming pool, spa or hot tub, its plumbing, gas or drainage piping, or its heater, fixture or water treating equipment first states in writing the character of work proposed. Permit fees are those in the most recently adopted fee schedule.
The chapter defines a swimming pool as any structure intended for swimming or recreational bathing that contains water over 18 inches deep, including in-ground, aboveground and on-ground pools, hot tubs, spas, portable spas and nonportable wading pools. Section 15.08.093 adds Subsection 3109.1 to the 2025 California Building Code, requiring the design and construction of pools, spas and hot tubs to comply with the International Swimming Pool and Spa Code. It also requires that whenever any building permit is issued and an existing pool, toddler pool or spa is on the property, the suction outlet be updated with an anti-entrapment cover meeting current ASTM or ASME standards.
Section 15.22.033 covers unpermitted work. Anyone who starts pool, spa or hot tub work without the required permit pays an administrative penalty equal to the inspection fee portion of the permit fee, in addition to the permit fee. Emergency work is excepted when the Administrative Authority is satisfied it was urgently necessary and impractical to permit first, but a permit must then be obtained by the next business day.
Section 15.22.045 sets barrier rules that inspectors check. The barrier top is at least 60 inches above grade, the gap at the bottom is at most 2 inches, openings cannot pass a 4-inch sphere, and pedestrian gates open outward and are self-closing and self-latching. Doors from the dwelling need an alarm sounding for a minimum of 30 seconds. The San Diego County Health Department is authorized to enforce the code under its agreement with the city (Section 15.22.015). Section 15.40.020 requires an annual operating permit only for public swimming pools, not private ones.
Violations & Fines
Starting pool, spa or hot tub work without a permit costs an administrative penalty equal to the inspection fee portion of the permit fee, on top of the permit fee (Section 15.22.033). A violation of the swimming pool code is punishable as a misdemeanor under Chapter 1.20 (Sections 15.22.020 and 15.22.022), with a fine not exceeding one thousand dollars or six months in jail, or both. Section 15.08.050 also lets the city deny a building permit where a code violation exists on the property.
