Buying Land in Putnam County, Ohio
Seat Ottawa, in Ohio's flat, fertile northwest corner. Putnam County is one of the state's most heavily farmed counties -- soybeans cover more than half its farmland acreage -- and its roughly fifteen townships appear to handle zoning individually rather than through a countywide rural zoning resolution. Here's what to confirm before buying.
A top-tier Ohio farmland county
Putnam County ranks third among all 88 Ohio counties for total farmland acreage, with an estimated 190,701 acres spread across 1,435 farms -- soybeans alone cover more than half the county's farmland. That agricultural intensity shapes the land market here: much of what's available is working cropland rather than idle acreage, land values track commodity and cash-rent economics as much as development potential, and a buyer looking for recreational or homestead-scale land should expect to be evaluating parcels carved out of, or adjacent to, active row-crop operations rather than long-vacant rural tracts.
Zoning: township by township, not countywide
This research pass found no evidence that Putnam County has adopted county rural zoning under ORC Chapter 303 -- there's no indication of a Putnam County Rural Zoning Commission analogous to the ones larger Ohio counties maintain. Instead, the Putnam County Planning Commission (the Board of County Commissioners plus eight appointed citizen members) administers subdivision and floodplain regulations and supports township zoning officials, which reads as the county playing a coordinating and technical-assistance role while zoning authority itself sits with individual townships under ORC Chapter 519.
One county building-process document identifies Blanchard Township as not zoned, and Greensburg, Jackson, Jennings, and Liberty Townships as zoned -- useful as a partial data point, but Putnam County has roughly fifteen townships total (including Palmer, Pleasant, Riley, and Union, among others), and this pass could not confirm the zoning status of the remainder. Before buying land in any specific Putnam County township, contact that township's zoning inspector (or the county Planning Commission if the township directs you there) to confirm whether zoning applies at all, and if so, what district and setback rules govern the parcel.
Septic, water, and other departments to know
The Putnam County Health Department's Environmental Health Division (419-523-5608) is the single point of contact for household sewage treatment systems and private water systems anywhere in the county. A site evaluation is required before a new septic permit can be issued on any buildable lot, and every household sewage treatment system needs a five-year Operation & Maintenance permit ($75, renewable) that requires the tank be pumped at least once every ten years and the system evaluated once each five-year cycle. Private water system permits -- covering new wells, existing wells being connected to a new dwelling, and even ponds used as a water source -- also run through this same office.
For parcel records, the Putnam County Auditor (245 E. Main St., Ottawa; 419-523-6686) and Recorder (same building, Suite 202; 419-523-6490) hold property valuations, deeds, and easements, and the Putnam County Engineer (Suite 205; 419-523-6931) is the right contact for road-frontage, access, and drainage questions on rural parcels.
