Full Breakdown
300(A), which bars anyone from constructing any structure or installation, pools included, without first obtaining one. 310(A)(13)-(14): swimming, bathing and wading pools and fish ponds no more than 18 inches deep need no permit, and prefabricated pools, spas or hot tubs accessory to a single-family (Group R-3) home need no permit if they rest on the ground or a ground-level concrete slab and are no more than four feet deep. Anything larger, in-ground, or structurally supported needs a building permit. 170. 040(C) further makes the state Swimming Pool Safety Act mandatory: the barrier requirements in Appendix Chapter I of the California Residential Code apply to reflect Health and Safety Code Sections 115920 through 115929, cross-referenced to California Building Code Section 3109. 410). 460(C).
Violations & Fines
Building an in-ground pool, or any prefabricated pool, spa or hot tub deeper than four feet or not resting on the ground, without first securing a Chapter 7.28 permit violates Dublin Municipal Code Section 7.28.230, is prosecuted under Section 1.04.030, and is a public nuisance abatable under Chapter 7.52 (Section 7.28.270). Starting work early also triggers a penalty fee under Section 7.28.460(C): the permit fee again for a first offense within two years, double for a second, ten times the fee for a third.
