STATE LICENSE
NoneSee what applies
Ohio does not license pool service technicians or companies. The regulated party is the pool: under R.C. 3749.04 no one may operate or maintain a public swimming pool, public spa or special use pool without an annual license from the local licensor (health department), running to the last day of May. The licensee must keep operating personnel trained in equipment, chemical handling and on-site testing, test disinfectant, combined chlorine and pH before opening and every four hours while open, and keep records for two years (OAC 3701-31-04) — duties a hired service company performs on the licensee's behalf.
Installation is a city credential: Columbus licenses 'Residential swimming pools and spas' as a Home Improvement Limited specialty, and Toledo's Limited Remodeling Contractor covers swimming pools more than 24 inches deep. Pool electrical work follows the electrical rules — OCILB license for commercial, city registration for residential.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Two local layers apply. Public pools are licensed annually by the local health district acting as licensor under R.C. 3749.04, with fees capped at the cost of licensing and inspection. Installation is licensed by cities: Columbus lists residential swimming pools and spas as a Home Improvement Limited specialty (one year of experience, board approval, $300 application plus $350 annual fee), Toledo licenses pools over 24 inches deep under its Limited Remodeling Contractor class, and Cincinnati and Akron require contractor registration before permits issue. Pool electrical bonding and equipment wiring follow the electrical rules — OCILB for commercial, city electrical registration for residential.

Pending verification: Whether applying EPA-registered pool algaecides or sanitizers for hire triggers ODA commercial applicator licensing — ODA's aquatic category excludes swimming pools, but no ODA statement on pool service was found · Whether OAC 3701-31 requires a specific operator certification (e.g., CPO) for public pools — the rule text fetched requires training but names no certification
