Sourced from OAC 3701-29, county health district documentation, and Ohio EPA HSTS transfer requirements — last checked August 2026.
Why There’s No Single Answer
Ohio sets minimum standards through OAC 3701-29 and leaves permitting, inspection and enforcement to local health districts. Districts may adopt rules more stringent than the state minimum, and point-of-sale inspection is exactly the kind of thing some have added and others haven’t.
The result is a patchwork. Two neighboring Ohio counties can have completely different requirements for the same transaction, which is a reliable source of confusion for buyers, sellers and even agents working across county lines.
Your local health district is the only reliable source. Ask early, not two weeks before closing.

What Does Your Ohio County Require?
Ohio sets statewide minimum standards in OAC 3701-29, but local health districts may adopt more stringent rules — and many have. With 88 counties writing their own supplemental codes, the honest answer to most specific questions is “it depends where you are.” This tells you what to ask.
Directional guidance only. Ohio’s 88 local health districts administer permitting and enforcement, and may adopt standards more stringent than OAC 3701-29. The Ohio Department of Health maintains a directory of local health districts.

The Requirement That Applies Everywhere
The form is straightforward. Only the new homeowner’s signature is required, electronic signature is accepted, and if you don’t know the previous owner’s information that section can be left blank.
Email it to DSW.HSTS@epa.ohio.gov, or mail it to Ohio EPA Division of Surface Water, Attn: HSTS group, 50 West Town Street, Suite 700, Columbus, Ohio 43215. You’ll receive an updated approval letter with the permit number in your name.
What to Ask Before Closing
Does this county require an inspection or evaluation at point of sale? If so, who’s qualified to perform it and what does it cost?
What records does the health district hold for this property? Permits, as-built drawings, inspection history. On older rural properties there may be nothing, which is itself worth knowing.
Is there a current operation permit? Every Ohio system needs one, and it should be current.
Does the system discharge off lot? If yes: is there an Ohio EPA NPDES permit, and has the coverage transfer been handled? Also worth knowing that the current general permit expires December 31, 2026.
Is the annual sampling current? For discharging systems this is a real obligation, and a lapsed record is a question mark you’d rather resolve before closing than after.
For Sellers
Getting ahead of it is cheaper than reacting to it. Find out what your county requires, pull your permit file from the health district, pump the tank and keep the receipt, and gather your maintenance records.
If your system discharges off lot, make sure the buyer knows about the transfer form and the annual sampling requirement. Surprises discovered after closing become disputes; disclosed obligations are just part of the property.

Frequently Asked Questions
Does Ohio require a septic inspection before selling a home?
Not statewide. Many of Ohio 88 counties have adopted point-of-sale requirements and many have not, so the answer depends on which county the property is in.
What applies statewide when selling a home with septic?
If the system discharges off lot, Ohio EPA requires a General Permit Coverage Transfer form when ownership changes, regardless of county rules.
How do I file the Ohio EPA transfer form?
Only the new homeowner signature is required, electronic signature is accepted, and the previous owner information may be left blank if unknown. Email it to DSW.HSTS@epa.ohio.gov.
What should I ask my health district before buying?
Whether the county requires a point-of-sale inspection, what records exist for the property, whether there is a current operation permit, and whether the system discharges off lot.
