Read this before you act on anything below. This is my researched starting point for Guernsey 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 rulesGuernsey County, OH

Zoning & raw-land occupancy

Varies locallyNo countywide zoning ordinance; zoning is regulated township by township under Ohio's township zoning authority (ORC 519). Subdivided land must meet Guernsey County Planning Commission standards. source

Dwellings, tiny homes & RVs

Varies locallyDwelling type rules (tiny homes, RVs as residences) are set by township zoning, not confirmed at county level. Manufactured home installs need a permit in advance and the County Auditor/Treasurer must be notified afterward. source

Building permits & codes

Generally allowedThe Mid-East Ohio Building Department, a regional certified building department covering Guernsey County, issues permits and inspects under the Ohio Building Code/Residential Code of Ohio. Manufactured home installation licensing is separately handled by the Ohio Department of Commerce. source

Septic & composting toilets

Generally allowedThe Cambridge-Guernsey County Health Department administers Ohio's statewide sewage treatment system rules locally, with an operation-and-maintenance permit program; requirements differ for systems installed before vs after January 1, 2015. Composting toilets are not separately addressed in county guidance found. source

Greywater reuse

Generally allowedGreywater recycling systems are folded into the health department's sewage treatment system operation-and-maintenance program, consistent with statewide OAC 3701-29 rules. source

Rainwater harvesting

Unclear - verifyNo Guernsey-specific rainwater/cistern ordinance was found; cisterns appear as a private water system category in health department fee materials, implying the state baseline (OAC 3701-28) applies. Confirm specifics with the health department. source

Private wells & water rights

Generally allowedThe Cambridge-Guernsey County Health Department issues permits for new private water systems, well conversions, alterations, and well sealing under the statewide OAC 3701-28 framework. source

Living disconnected from utilities

Unclear - verifyNo Guernsey County ordinance requiring connection to electric, water, or sewer utilities was found; a habitable home still must meet the Residential Code of Ohio as enforced regionally, but that's not the same as a hookup mandate.
