Summary
Building a residential swimming pool in the City of Tustin requires a permit under City Code § 8102(h), which amends California Building Code § 3109.1, setting engineering standards for expansive soil, setbacks from slopes, and mandatory continuous special inspection for gunite and cast-in-place concrete pools, covering electrical bonding, reinforcing steel, anchor bolts and concrete strength.
3109.1 Construction requirements. (a)All pool construction shall be in conformance with engineered design for expansive soils, unless a soils report by a registered engineer approved by the Building Official indicates otherwise.(b)The pool shall be constructed not less than seven (7) feet from the top of a cut, fill or natural earth slope, not less than five (5) feet from toe of a cut, fill or natural earth slope.(c)A continuous inspection by a special inspector shall be required on all pools constructed of reinforced gunite, or reinforced cast in place concrete. Said special inspector shall ensure all electrical bonding is properly installed; ensure all required reinforcing steel and diving board or slide anchor bolts are properly in place, ensure concrete is cast to the thickness required for expansive soil ... and take test samples during the placing of concrete and such samples shall be tested by an approved testing laboratory to attain a strength exceeding two thousand (2,000) psi, or as required by the design engineer at twenty-eight (28) days.
Full Breakdown
Tustin's amendment to California Building Code Section 3109.1, adopted at City Code § 8102(h), requires all pool construction to conform to an engineered design for expansive soils unless a registered engineer's soils report shows otherwise. Pools must sit at least seven feet from the top of a cut, fill or natural earth slope, and at least five feet from the toe of one, a setback meant to keep pool excavation from destabilizing adjacent grade. Any pool built of reinforced gunite or reinforced cast-in-place concrete requires continuous inspection by a special inspector, who must confirm electrical bonding is properly installed, reinforcing steel and diving-board or slide anchor bolts are correctly placed, the concrete is cast to the thickness the expansive-soil design calls for, and the concrete itself is properly placed.
The special inspector also pulls test samples during the pour, which an approved testing laboratory must test to a strength exceeding 2,000 psi, or whatever higher strength the design engineer sets, at 28 days. If a test shows the concrete is deficient or of questionable strength, the special inspector can require core tests with the Building Official's approval, and must file a written report on inspection dates and lab results confirming the reinforcing steel, expansive-soil details, drawings, and footing and anchor-bolt work all comply with the approved plans before the pool can be signed off.
Violations & Fines
Building or altering a pool without the required permit, or pouring gunite or cast-in-place concrete without the mandated continuous special inspection, is a Building Code violation under the Tustin City Code's general penalty provisions, an infraction or misdemeanor enforced by the Building Official, with the pool work subject to correction, re-inspection or removal until it passes.
