State CPO Requirements in 2026: How Pool Operator Rules Actually Work

License or certificate?

The CPO is a certificate from the Pool & Hot Tub Alliance. You earn it by passing the exam, and it is good for five years. In most places, a certificate from an approved course is what the inspector wants to see.

A few places add something of their own. Pima County in Arizona certifies operators through its own class and exam. Wake County in North Carolina offers its own free test. Fort Worth, Texas runs its own operator course. If your pool is in one of those, you may need their step as well as, or instead of, a national certificate.

Three layers of rules

The state rule. Usually part of the state administrative code, written by the health department. It sets water quality, record keeping and, in many states, the operator requirement. Texas, Florida, Georgia, North Carolina and Utah all have one.
The county or city. The local health department permits and inspects the pool, and some add their own operator rules. In California and Arizona, that is where the operator requirement lives.
Your employer, board or insurer. They can expect a certified operator even where the law does not.

On site or on call?

This line decides how many people on your staff need the card, so read it closely.

Texas says the certified operator does not have to be on site whenever the pool is open.
Georgia sets a minimum of two operator visits a week, and when the operator is away it wants a trained person on site who can test the water.
Pima County wants a certified operator on duty at public pools, and on duty or on call at semipublic pools.

Which pools count as public?

More than most people expect. North Carolina’s rule covers hotel, motel, apartment and club pools. California’s Title 22 counts HOA pools as public pools. Georgia may leave out pools open only to residents and their guests, depending on the county. If people from more than one household use the pool, treat it as regulated until your health department tells you otherwise.

Keeping it current

The PHTA CPO is good for five years, counted from the end of the month you passed. If your card is still current, PHTA lets you recertify by attending just the second day of a CPO class, which is the review and the exam. Put the expiration date on your calendar. Keep a copy of the certificate with your pool records, and post it where your rules require it. Washoe County, Nevada, for example, requires the CPO certificate to be posted on site.

Finding your rule

Start with which states require CPO certification, or go straight to the state pages at CPO certification by state. Then call your county health office and ask what they want to see on inspection day.

Frequently Asked Questions

Is there a national pool operator license?

No. There is no federal pool operator license. The PHTA CPO is a national certification, and whether you need it is set by your state and local health department.

Do I need a CPO for an HOA or apartment pool?

It depends on where you are. California counts HOA pools as public pools under Title 22, and North Carolina’s rule covers apartment and club pools. Ask your county health department.

How many people on my staff need the CPO?

Where a certified operator is required, at least one. Whether you need more depends on whether your rule wants the operator on site while the pool is open.
