An educational, cited reference for homeowners — not a claim that ClickSeptic services Ohio today. ClickSeptic has zero live markets anywhere yet.
Short answer: The Ohio Department of Health (ODH) sets statewide rules for household sewage treatment systems (HSTS, serving 1-3 family dwellings) and small-flow on-site systems under Ohio Revised Code Chapter 3718 and Ohio Administrative Code Chapter 3701-29, effective January 1, 2015. Local city or county boards of health/health districts implement these rules directly — issuing permits, conducting site reviews, and enforcing operation permits — and ORC 3718.02 allows local boards to adopt more stringent standards after considering economic impact. Ohio EPA separately handles NPDES permits for systems that discharge to surface waters.

Ohio has no single statewide law requiring septic inspection at every home sale; instead, ORC/OAC provisions authorize local boards of health to adopt time-of-transfer inspection ordinances, and many Ohio counties have done so, requiring a passing HSTS inspection before closing. Where a county has not adopted such a rule, no state-level point-of-sale inspection is triggered by the sale itself, though the existing operation permit and its conditions transfer to the new owner.
Ohio does not set one flat statewide pumping interval; instead OAC 3701-29-09 requires every household sewage treatment system to operate under a valid local operation permit whose term (set by the local board, not exceeding limits in rule) dictates inspection/service cadence — for example, Warren County Health District issues 10-year permits for conventional non-discharging systems with one inspection per term, while Lake County requires one pump or service report every 5-year permit term, and Hamilton County inspects non-mechanical systems roughly every 58 months. Actual pumping frequency is therefore governed by the local operation-permit schedule rather than a single number in state code.
Permits are issued locally: city or county boards of health/general health districts review soil/site evaluations and issue installation, alteration, repair, and abandonment permits, plus the ongoing 'operation permit' required to legally run an HSTS under OAC 3701-29-09. ODH sets the statewide minimum rules those local permits must follow but does not issue individual homeowner permits itself.
Ohio's operation-permit system is distinctive: rather than a one-time installation permit, every household sewage system must carry a continuously valid, renewable local operation permit (OAC 3701-29-09) whose maintenance/monitoring/service-contract conditions are enforceable ongoing obligations, and that permit automatically transfers to a new owner at sale, making disclosure of its terms a seller responsibility.
