Read this before you act on anything below. This is my researched starting point for Knox County, OH, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesKnox County, OH

Zoning & raw-land occupancy

Varies locallyKnox County has no unified zoning code; each township adopts its own zoning resolution under Ohio Revised Code Chapter 519, coordinated by the Knox County Regional Planning Commission. Minimum lot sizes and raw-land rules differ by township, so you must check with your specific township. source

Dwellings, tiny homes & RVs

Varies locallyTiny home, manufactured home, and RV occupancy rules are set township by township, not countywide; contact the specific township zoning inspector for your parcel. source

Building permits & codes

RestrictedBuilding permits are administered at the county level through the Knox County Regional Planning office, following the state Residential Code of Ohio; new lots may require a Minor Subdivision/Lot Split review and an approved driveway/access point. source

Septic & composting toilets

RestrictedSeptic systems are permitted but require a site evaluation and an Operation Permit from the Knox County Health Department for the life of the system, under state ODH rules following a 2015 statewide law change. source

Greywater reuse

Generally allowedRainwater harvesting via cistern appears to be allowed as part of the county's private water system category, with no Knox-specific restriction found beyond the state OAC baseline; not fully confirmed.

Private wells & water rights

RestrictedPrivate wells require a permit from the Knox County Health Department, which administers Ohio's private water system rules (OAC 3701-28), including site plans for construction, alteration, or sealing of wells.

Living disconnected from utilities

Unclear - verifyNo blanket countywide requirement to connect to utilities was confirmed for areas without public service, but Knox County Sanitary Regulation No. 17 requires connecting to public sewer and abandoning private septic where such service is available. source
