Swimming Pools & Spas in Fresno, CA

If you live in Fresno or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Fresno has 2 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.

Fencing & Safety Requirements

Every residential swimming pool, spa, or hot tub in Fresno that holds more than 18 inches of water must be surrounded by an enclosure at least 60 inches high, with self-closing, self-latching gates that open away from the pool. The City enforces the California Swimming Pool Safety Act (Health & Safety Code 115920-115929) through the 2022 California Residential Code, and the City's own Consumer Notice reproduces the barrier standard verbatim.

Key details: Code Section: Cal. Health & Safety Code Sec. 115923. Governing act: California Swimming Pool Safety Act (HSC 115920-115929). Minimum enclosure height: 60 inches. Max ground clearance: 2 inches. Max gap: No 4-inch sphere may pass.

All enclosure fencing, self-closing devices, exit alarms, safety glazing, and gate or door safety hardware must be in place, inspected, and approved before the pool is plastered or filled with water. Over-height, dilapidated, or non-conforming fencing can be reported to City Code Enforcement at (559) 621-8400 and is abated as a municipal code violation.

Pool Permits

Building a swimming pool or spa in Fresno requires a construction permit, and whenever that permit is issued for a new or remodeled pool the pool must be equipped with at least two of seven specified drowning-prevention safety features under Health & Safety Code 115922. Only small prefabricated above-ground pools accessory to a single-family home that are less than 24 inches deep and hold no more than 5,000 gallons are exempt from the building permit.

Key details: Code Section: Cal. Health & Safety Code Sec. 115922. Safety features required: At least 2 of 7 drowning-prevention features. Permit authority: City of Fresno Development & Resource Management. Permit exemption: Prefab above-ground pool < 24 in deep, <= 5,000 gal, R-3 only. Consumer notice: Required by HSC Sec. 115924.

Before the pool is plastered or filled, the barrier, gates, self-closing devices, exit alarms, and safety hardware must be in place, inspected, and approved; the local building official inspects the required drowning-prevention features prior to final approval. Constructing a pool without the required permit, or filling it before inspection approval, is a code violation subject to stop-work and after-the-fact permitting. Permit questions: City Planning (559) 621-8277.

The Bottom Line

Fresno's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Fresno is broadly strict or permissive.
