Off-grid living in Ohio: a property guide
Ohio’s rules expressly cover more than wells: springs, cisterns, ponds, hauled water and recycled water can all be private water systems. Each proposed source needs local health approval—and must fit beside an approvable sewage system.
Source is not a loophole
Choose a pathway the health district can approve.
Construction, siting, testing, record and registered-contractor requirements.
Source development, protection, treatment and sampling under the private-water rules.
Collection, storage, treatment, weather protection and approved construction.
Approved source, transport, storage, treatment and continuing delivery feasibility.
System-specific plans, treatment and approval; not presumed potable because water is present.
The statutory private-system category generally applies below 15 service connections and below an average of 25 people daily for 60 days a year. Crossing that boundary changes the regulatory program.
Private water approval
Application, inspection, sample, approval.
Rule 3701-28-03 prohibits construction, alteration or sealing of a private water system or test well without a valid board-of-health permit, subject to listed exceptions. A new or altered system is not approved until the required sample meets the applicable standard.
- 1 Identify the city or general health district.
- 2 Submit the source-specific plan, site data and permit fee.
- 3 Use a registered and bonded contractor for covered work.
- 4 Complete construction records, inspection and sampling.
- 5 Preserve final approval and continuing maintenance plan.
Household sewage treatment
Local health district, state rules, site-specific design.
Ohio’s household program covers systems for one-, two- and three-family dwellings. Local health districts issue permits, enforce the code, investigate nuisances and conduct operational inspections; they may adopt more stringent standards.
Depth, texture, structure, drainage and limiting conditions determine the treatment/dispersal option.
Bedrooms and actual use determine design assumptions; home business or other use can change program scope.
Protect the installed system and replacement area from structures, traffic and other utilities.
Some systems require service contracts, sampling, reporting or operational permits after installation.
A system discharging off lot requires Ohio EPA NPDES general-permit coverage in addition to the local household-sewage pathway. Start with the local health department.
Follow the official jurisdiction guidanceDwelling approval
Systems approval does not authorize occupancy.
The Ohio Residential Code governs one-, two- and three-family dwellings. Identify the certified building department for the property, then resolve zoning, plan review, building and trade permits, inspections and final occupancy separately from health approvals.
