Pool operator requirements in Illinois
Quick answer
Does Illinois require a certified pool operator?
No. Illinois does not mandate a certified pool operator. Under the Swimming Facility Code, 77 Illinois Administrative Code 820, a designated manager/operator must be responsible for running the facility in compliance, but the code names no CPO or AFO certification. The Illinois Department of Public Health writes and enforces the rule.
- Certified operator required?
- Not required Section 820.300 requires that a swimming facility manager/operator be designated and be responsible for operating the facility in compliance with the code, but it does not require that person to hold a CPO, AFO, or any named certification. Only lifeguards must carry a recognized certification.
- Certifications accepted
- None named at the state level No operator certification is named in the code. Where an employer or a local health department wants documented competence, the PHTA Certified Pool Operator (CPO) and the NRPA Aquatic Facility Operator (AFO) are the credentials most widely recognized. Confirm any local rule with your certified local health department.
- Governing agency
- Illinois Department of Public Health (statewide rules and enforcement); certified local health departments permit and inspect under delegation
- Regulation citation
- 77 Illinois Administrative Code 820 (Swimming Facility Code, formerly the Swimming Pool and Bathing Beach Code)
- CDC Model Aquatic Health Code
- Illinois regulates public pools through its own Swimming Facility Code, 77 Illinois Administrative Code 820, rather than adopting the CDC Model Aquatic Health Code.
- Renewal / operator presence
- Illinois issues no state operator credential to renew. If you earn a CPO, it runs on the national five-year recertification cycle.
Illinois is a state that regulates public pools in real detail while never requiring the operator to be certified. If you are studying for the CPO because an Illinois employer expects it, that is an employer or local rule, not a mandate written into the state’s Swimming Facility Code.
Who this applies to
This page covers public swimming facilities: pools other than a private single-family home’s pool, including apartment, hotel, health-club, HOA, school, and municipal pools, along with bathing beaches. Illinois brings that whole class under 77 Illinois Administrative Code 820, the Swimming Facility Code the Department of Public Health uses to permit and inspect these facilities.
Does Illinois require a certified pool operator?
No. Section 820.300 of the code states that a swimming facility manager/operator shall be designated and shall be responsible for the operation of the swimming facility in compliance with the rules. It stops there: it does not require that manager/operator to hold a CPO, an AFO, or any named credential. The legal duty is that a responsible person runs the pool correctly, not that they carry a specific certificate.
Interestingly, the same section does require certification for a different role: lifeguards must be currently certified by the American Red Cross, the National Pool and Water Park Lifeguard Training Program, the YMCA, or an equivalent program. So Illinois clearly knows how to require a credential when it wants to, and it chose not to for the operator.
Which certification counts
Because the code names no operator certification, there is no official “accepted list.” In practice the two credentials employers recognize are the PHTA Certified Pool Operator (CPO) and the NRPA Aquatic Facility Operator (AFO). The CPO is the more widely recognized nationally. Compare them in our CPO vs AFO guide, and see how to become a CPO for the course-and-exam path.
The governing law, in plain terms
- 77 Illinois Administrative Code 820 is the Swimming Facility Code (formerly the Swimming Pool and Bathing Beach Code).
- The Illinois Department of Public Health writes the code and issues construction permits and operating licenses.
- In many areas a certified local health department permits and inspects pools under delegation, so your enforcing agency may be a county or city health department.
- The code sets the substance the operator must meet: personnel, disinfection and water quality, recirculation, and safety equipment.
Illinois uses this state framework rather than adopting the CDC Model Aquatic Health Code, so the numbers your inspector enforces come from Part 820, confirmed with your local health department’s plan review and operating permit.
How to comply in practice
- Find your enforcing agency. It may be the state or a certified local health department that inspects against Part 820.
- Designate a responsible manager/operator. The code requires the role; it does not require the certificate.
- Certify your lifeguards. That credential is required where lifeguards are used.
- Consider a CPO if your employer or insurer wants documented competence, even though the state does not require it.
