40.6926, -82.5108Read this before you act on anything below. This is my researched starting point for Richland 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 rulesRichland County, OH
Zoning & raw-land occupancy
Varies locallyRichland County has no countywide zoning code; zoning is set township-by-township and by municipalities. 13 of 18 townships are zoned, 5 are unzoned, so raw-land occupancy rules vary by location, per Richland County Regional Planning Commission.
Dwellings, tiny homes & RVs
Varies locallyOhio state law prevents townships from banning permanently sited manufactured homes where single-family homes are allowed, but townships can restrict travel trailers, park trailers, and non-permanent mobile homes. RVs and tiny homes as permanent dwellings depend on the specific township's zoning code. source
Building permits & codes
Generally allowedThe Richland County Building Department administers the state Residential Code of Ohio for most of the county, requiring a site plan and zoning approval where applicable, plus stormwater permits in Soil and Water Conservation District jurisdiction. source
Septic & composting toilets
Generally allowedRichland Public Health administers septic/sewage permitting under Ohio Revised Code and OAC 3701-29 rules, covering site evaluation, system approval, and recordkeeping. Composting toilets specifically are not separately addressed on county pages. source
Greywater reuse
Unclear - verifyNo Richland County or Richland Public Health page specifically addresses greywater reuse; the state OAC 3701-29 framework likely applies as a baseline. Confirm directly with Richland Public Health.
Rainwater harvesting
Generally allowedRichland Public Health explicitly includes rainwater cisterns as a recognized private water system category, regulated under Ohio's Private Water System Rules (OAC 3701-28), administered locally by the health district. source
Private wells & water rights
Generally allowedPrivate wells are permitted through Richland Public Health under the state's Private Water System Rules (OAC 3701-28), which took effect in their current form in 2020 and are administered at the county level. source
Living disconnected from utilities
Unclear - verifyNo Richland County ordinance found mandating utility hookups. Properties inside Richland County Wastewater's sewer service districts (parts of Madison, Mifflin, Jackson, Springfield Townships) may face connection requirements set at the sewer-district level; outside those districts, septic and wells are standard and permitted. source
