Off-Grid Living in Cuyahoga County, Ohio

Cuyahoga County is a strange one to research because, structurally, there is no countywide zoning code at all. Ohio law leaves zoning to each of the county's 59 cities, villages, and townships, so whether you can occupy raw land, park an RV, or build a tiny house depends entirely on which of those 59 jurisdictions your parcel sits in. The Cuyahoga County Planning Commission (CPC) plays an advisory and regional-planning role, and it's currently working on a "Unified Zoning Code" initiative to bring more consistency, but as of this writing that hasn't replaced the patchwork. The one place county government does have direct zoning-adjacent authority is subdivision of land in unincorporated townships, which CPC regulates under Ohio Revised Code 711.09.

Building permits follow the same pattern: there's no county building department. Cleveland, Cleveland Heights, Lakewood, Parma, and every other municipality or township issues its own permits under its own code. Before you do anything structural, you need to find out which local building department has jurisdiction over your address.

On tiny homes and RVs, I didn't find a county ordinance, so again it's local. The one statewide backstop worth knowing: Ohio Revised Code 519.212 says townships can't use their zoning powers to ban a permanently sited manufactured home from a district that allows single-family homes, though they can still restrict non-permanently-sited trailers and mobile homes.

Where the county does step in clearly is environmental health, through the Cuyahoga County Board of Health (CCBH). CCBH administers Ohio's household sewage treatment system rules and, notably, layers on its own annual operation and management permit for anyone using a septic system, a program it's run since 1993. Greywater recycling systems are explicitly folded into CCBH's supplemental rules, so they're permitted but regulated the same way septic is. Private wells work the same way: CCBH issues the well permits required under state rule OAC 3701-28-03, handles well sealing and abandonment too, and there's a modest fee for sealing (confirm the current amount with CCBH directly, I'm not going to guess at a figure that may have changed).

Rainwater harvesting doesn't appear to have any county-specific rule; the state's private water system framework is the baseline, and I found nothing from CCBH or CPC narrowing or expanding on it.

On full utility disconnection, I found no ordinance flatly requiring or banning it. But because CCBH's septic and well permitting is mandatory regardless of grid connection, "off-grid" here still means you're on CCBH's radar for water and waste, even if you're off the electric grid entirely.

Bottom line: for zoning, dwellings, and building permits, your town or township is the real authority. For septic, greywater, and wells, it's CCBH countywide.
