Do I need a permit for retaining wall construction in Unincorporated Henry County?
Unincorporated Henry County does not issue residential building permits. No certified residential building department serves unincorporated Henry County, so no county residential building permit is issued there. Commercial work in Henry County is handled by the Wood County building department under the BBS non-residential list; that does not cover homes. Township zoning permits and county health district (septic and well) permits may still apply, and state-licensed electrical and plumbing rules still govern the work. Incorporated cities and villages may run their own certified departments.
The requirements below come from Ohio rules and describe the standard the work must still meet. They are not a statement that Unincorporated Henry County will issue you a permit.
It depends. Whether retaining wall construction needs a permit in Unincorporated Henry County comes down to the details of your project.
Section 102.10 of the Residential Code of Ohio exempts from approval a retaining wall not over 4 feet high measured from the bottom of the footing to the top of the wall, unless it supports a surcharge such as a driveway, slope, or structure. Section 101.2 exception 14 places retaining walls outside the residential code unless they are associated with or necessary for the building or its egress. A wall that supports a house, garage, or exit path is regulated. A tall freestanding landscape wall can still fall under local zoning, grading, or drainage rules, so confirm with your local office before you build. Ohio's residential code is enforced only by residential building departments certified by the Board of Building Standards, at the city, township, or county level. Confirm which department covers your address. Where none is certified, the owner must still build to the RCO.
