n Oregon, public swimming pools and spas are regulated by the Oregon Health Authority (OHA) under Oregon Administrative Rules (OAR) Chapter 333, Divisions 060 and 062.
As of 2026, Oregon distinguishes between "General-Use" (municipal/public) and "Limited-Use" (hotels/apartments) facilities, with specific oversight requirements for each.
Oregon maintains strict water quality standards to protect against waterborne pathogens.
Water Chemistry (Standard Ranges):
Free Chlorine: Minimum 1.0 ppm for pools; 3.0 ppm for spas.
pH Levels: Must be strictly maintained between 7.0 and 7.8.
Water Clarity: The pool must be clear enough that the bottom is clearly visible at all times while the facility is open.
Certified Operator: Every public pool must be under the supervision of a Certified Pool Operator (CPO) or a "Responsible Supervisor" who is accessible whenever the pool is open.
Daily Logs: Operators must record disinfectant residuals and pH at least once daily (OAR 333-060-0200).
Oregon’s enclosure rules are designed to prevent unauthorized entry, particularly by children.
Height: The top of the barrier must be at least 4 feet (48 inches) above grade.
Gate Security: Pedestrian access gates must open outward (away from the pool), be self-closing, and self-latching.
Latch Height: To keep the release mechanism out of reach, it must be located at least 42 to 54 inches above the ground (depending on the specific local building code).
Ground Clearance: The maximum gap between the bottom of the fence and the ground is 4 inches (though 2 inches is recommended for non-solid surfaces).
The "4-Inch Sphere" Rule: No opening in the barrier may allow a 4-inch sphere to pass through.
Oregon is very specific about the "Functional Telephone" requirement (OAR 333-060-0210):
Hard-Wired Standard: The state generally requires a functional telephone or communication device that is hard-wired and capable of directly dialing 911.
Accessibility: The phone must be conspicuously provided and easily accessible to all users within the pool area.
Required Signage: A permanent sign must be posted at the phone listing:
Emergency Dialing Instructions (911).
The physical address of the aquatic facility.
2026 Modernization: For 2026, many facilities are transitioning to cellular-based landline replacements that meet Oregon's hard-wired accessibility standards while reducing traditional copper line costs.
Lifesaving Equipment: Every pool must have:
A 12-foot reaching pole (shepherd’s crook).
A U.S. Coast Guard-approved ring buoy with a throw line (1.5x the pool's width).
Lifeguards: Required for all "General-Use" pools and pools with water features over 6 feet high. Lifeguards must be at least 16 years old and hold current certification (e.g., StarGuard or Red Cross).
"No Lifeguard" Signage: For "Limited-Use" pools (hotels/condos) where no guard is present, a sign stating "Warning: No Lifeguard on Duty" is mandatory, along with rules prohibiting children under 14 from swimming without an adult.
OAR 333-060 (Public Swimming Pools Full Rules): The official state-level administrative rules.
Oregon Health Authority - Pools and Spas Portal: The central hub for plan reviews, license applications, and safety fact sheets.
Multnomah County - Pool and Spa Licensing: Local guidance for Portland-area operators, including 2026 health license fees.
Oregon Aquatic Facility Rules Fact Sheet #16 (Signage): A comprehensive visual guide to the mandatory signs required by OHA for 2026.
Note for 2026: Oregon has updated its Incident Reporting rules. Any injury requiring medical follow-up (doctor visit or ER) or any fatality must be reported by the pool operator to the OHA within 72 hours using the official state reporting form.
