Quick answer
Health inspectors at commercial pools check water chemistry on the spot, then review your chemical logs, drain and suction outlet covers, fencing and self-closing gates, safety and rescue equipment, required signage, chemical storage, operator certification and the filtration system. Most failed inspections come from missing or incomplete logs, out-of-range chemistry, or broken gates and drain covers.
- Inspectors test your water — have your log and test kit ready.
- Incomplete or missing logs are one of the most common violations.
- Main drain must be clearly visible from the deck.
- Operator certification (CPO/AFO) must be current if your code requires it.
The checklist inspectors use
| Area | What they look for |
|---|---|
| Water chemistry | FC/bromine and pH within limits; CC and CYA acceptable; spa ≤ 104°F |
| Records | Daily chemical log, testing frequency met, corrective actions, maintenance & incident logs |
| Water clarity | Main drain clearly visible from the deck |
| Suction outlets | VGB-compliant covers, secured, not broken or expired |
| Barriers | Fence intact; gates self-close and self-latch |
| Safety equipment | Rescue tube or ring buoy, reaching pole, first aid kit, emergency phone |
| Signage | Pool rules, capacity, depth markers, "no diving", emergency numbers |
| Circulation | Pump running, flow meter reading, filter pressure normal |
| Chemical storage | Locked, ventilated, incompatible chemicals separated, SDS available |
| Personnel | Certified operator on record; lifeguards where required |
Imminent health hazards that close a pool
Under the MAHC, some findings mean the pool closes on the spot until corrected. These include disinfectant below the minimum, pH below 6.5 or above 8.0, a main drain that cannot be seen, missing or broken suction outlet covers, spa temperature above 104°F, and a missing barrier. Your daily opening checklist should catch all of these before the gates open.
Five steps to be inspection-ready every day
- Keep the current month’s log at the pool, filled in through today.
- Run the opening safety checklist before opening, every day.
- Keep the test kit stocked with in-date reagents.
- File past logs in order so you can produce any date on request.
- Post your operator certificate and permit where required.
Frequently asked questions
What do pool inspectors look for?
Water chemistry, chemical and maintenance logs, drain covers, water clarity, fencing and gates, rescue and first aid equipment, signage, chemical storage, filtration, and operator certification.
What are the most common pool inspection violations?
Incomplete chemical logs, disinfectant or pH out of range, broken self-closing gates, missing safety equipment or signage, and damaged or unsecured drain covers are among the most frequently cited.
Can an inspector close my pool?
Yes. Imminent health hazards — such as no disinfectant, an invisible main drain, or broken suction covers — typically require immediate closure until fixed.
