Summary
In the City of Fountain Valley, California, a swimming pool needs a building permit unless it is a prefabricated, entirely above-ground pool accessory to a Group R occupancy that is less than 18 inches deep and holds no more than 5,000 gallons. Section 18.04.020 of the Municipal Code lists that single pool exemption, so every deeper or larger pool, spa or hot tub sits inside the permit system.
Section 105.2 of Chapter 1 of the California Building Code is amended in the following categories of work that are exempt from building permit: ... ... 9. Prefabricated swimming pools accessory to a Group R occupancy that are less than 18 inches deep, do not exceed 5,000 gallons and are installed entirely above ground.
Full Breakdown
Fountain Valley amends Section 105.2 of the California Building Code in Municipal Code § 18.04.020 to list the work that is exempt from a building permit. Sheds of 120 square feet or less with a ceiling under 7 feet, fences up to six feet, block walls up to three feet and retaining walls up to four feet are exempt. For swimming pools the list has exactly one entry: a prefabricated pool accessory to a Group R occupancy that is less than 18 inches deep, does not exceed 5,000 gallons and is installed entirely above ground. A pool that misses any one of those three limits is not exempt.
The code defines the term broadly in § 18.04.080. A swimming pool is any structure intended for swimming, recreational bathing or wading that contains water over 18 inches deep, and that includes in-ground, above-ground and on-ground pools, hot tubs, spas and fixed-in-place wading pools. A barrier is a fence, wall, building wall or any combination of these that completely surrounds the pool and obstructs access to it.
A permitted residential pool must be completely enclosed by a barrier under § 18.04.090. Section 18.04.095 sets the numbers: the top of the barrier at least 60 inches above grade, no more than two inches of clearance under the barrier, and no opening that passes a 4-inch sphere. Pedestrian gates open outward away from the pool, close on their own and latch on their own. The city also adopted the 2021 International Swimming Pool and Spa Code in § 18.33.010.
The building official runs the permit and inspection process. Under § 18.04.040 the official can refund up to 80 percent of a permit fee when no work has been done, but only on a written application filed within 180 days of payment. A person who disagrees with a building decision can appeal to the Planning Commission, which sits as the local appeals board under § 18.02.025, and can carry the matter further through Chapter 21.60. Every construction permit also carries the state strong motion instrumentation fee under § 18.36.030.
Violations & Fines
Starting pool work before the permit issues costs double the permit fees under § 18.04.030, plus a special investigation charge set by city resolution when the Building Official requires one. Under § 18.02.030 a Title 18 violation is a misdemeanor punishable by a fine of up to $1,000, up to six months in the County Jail, or both, and each day of violation counts as a separate offense.
