In Rhode Island, public and semi-public swimming pools (referred to legally as Licensed Aquatic Venues) are regulated by the Rhode Island Department of Health (RIDOH) under 216-RICR-50-05-4.
As of 2026, Rhode Island has fully codified emergency regulations into final rules, emphasizing "Self-Assessment" and strict barrier heights for outdoor facilities.
Rhode Island uses a tiered testing frequency based on whether your facility uses automation.
Water Chemistry (Standard Ranges):
Free Chlorine (Indoor): 1.0 – 10.0 ppm (Ideal: 2.0 – 4.0 ppm).
Free Chlorine (Spas): 2.0 – 10.0 ppm (Ideal: 3.0 – 5.0 ppm).
pH Levels: Must be strictly maintained between 7.2 and 7.8.
Testing Frequency:
Manual Systems: Must test pH and disinfectant every 2 hours while open.
Automated Systems: Must test every 4 hours while open.
Clarity: The main drain at the deepest point must be clearly visible. If the "bottom is not visible," it is considered an imminent health hazard, requiring immediate closure.
Cyanuric Acid: Prohibited in all indoor pools and all hot tubs/spas.
Rhode Island follows the 2021 International Swimming Pool and Spa Code (ISPSC) with specific state amendments that vary by pool type.
Outdoor Pools (General Rule): Per R.I. Gen. Laws § 23-22-6, outdoor pools must be surrounded by a fence at least 6 feet (72 inches) high.
Standard State Minimum: While the 6-foot rule applies to many licensed venues, some specific residential/semi-public codes allow for 4 feet (48 inches), though many towns (like West Warwick and Narragansett) mandate 5 to 6 feet locally.
Gate Security: All gates must open outward, be self-closing, and self-latching.
The "4-Inch Rule": No opening in the fence or under the fence (2-inch max ground gap) may allow a 4-inch sphere to pass through.
Rhode Island has specific rules for "Non-Surf" vs. "Surf" certifications for the 2026 season.
Lifeguard Requirements: No lifeguard is strictly required for most licensed pools unless the pool is used by a swim club or a group of unsupervised children.
"No Lifeguard" Signage: If no guard is on duty, you must post:
"NO LIFEGUARD ON DUTY—SWIM AT YOUR OWN RISK" (Minimum 4-inch RED letters).
"No one under 18 permitted unless accompanied by an adult."
First Aid: Facilities without lifeguards must have a person trained in First Aid physically located in "close proximity" to the pool.
The Pool Phone: RIDOH requires an emergency phone or communication device to be available and clearly marked at the pool (usually within 200 feet).
First Aid Kit: Must be continuously stocked and include a resuscitation mask with a one-way valve and a blood-borne pathogen spill kit.
Rescue Gear: Every deck must have:
A 12-foot reaching pole (shepherd's crook).
A U.S. Coast Guard-approved ring buoy with an attached throw line (1.5x the pool's width).
Rhode Island uses an Annual Self-Assessment Checklist that operators must complete to ensure compliance before seasonal opening.
Critical hazards that require immediate closure include:
Unprotected overhead electrical wires within 20 feet.
Missing or broken main drain grates (VGB Act compliance).
Lack of GFCI protection on outlets within 20 feet.

Note for 2026: In Rhode Island, all pools must operate their filtration and disinfection systems 24 hours a day. If a pump fails or is turned off, the pool is considered an "imminent health hazard" and must be closed to the public immediately.
