Full Breakdown
San Marcos Code Sec. 14.002(a)(10) adopts the International Swimming Pool and Spa Code, 2021 Edition, as one of the city's construction codes, so new residential pools go through the same building-permit process as other construction, administered by the building inspection division within Planning and Development Services. Sec. 14.371(15) makes it unlawful to fill a pool that is part of a building permit before it passes a required pool barrier inspection, so the barrier or fence must be built and approved before the pool can hold water.
Violations & Fines
Filling a permitted pool before it passes its pool barrier inspection is a misdemeanor punishable by a fine of at least $250 per occurrence; performing permitted construction work without the permit is separately prohibited.
