Full Breakdown
The City's Swimming Pool and Spa Code amendments rewrite ISPSC Section 305.1 to require a barrier around every aquatic vessel, pool, spa, or hot tub, designed to restrict access and prevent drowning or near-drowning. The rule calls for an integrated system of physical barriers plus warning devices, not just a fence around the yard. The Department of Transportation, Engineering and Development enforces the requirement through the building permit and inspection process tied to the City's adoption of the 2024 International Swimming Pool and Spa Code. Homeowners installing or replacing a pool barrier should confirm their design meets Section 305.1 before requesting final inspection.
Violations & Fines
Building without an approved barrier blocks issuance of an occupancy or final inspection sign-off; the City can order corrections and withhold permit closeout until the barrier meets Section 305.1.
