Full Breakdown
Section 24.02.120(A)(12) of the San José Municipal Code lists building-permit exemptions and excuses 'prefabricated swimming pools accessory to a Group R-3 occupancy that are less than 24 inches deep, are not greater than 5,000 gallons and are installed entirely above ground.' Any pool exceeding either threshold, any in-ground pool, or a permanent (non-prefabricated) structure needs a building permit from the Building Division before installation. The exemption only waives the building permit: separate electrical permits can still apply for pump or filter wiring, and a pool 18 inches deep or more still triggers the enclosure/fencing rules in Chapter 17.28.
Violations & Fines
Installing any pool without a required permit is unlawful under SJMC § 24.01.130; code enforcement can red-tag the work, require removal or retroactive permitting, and cite the property as a title violation.
