Do I need a permit for deck construction or replacement in Unincorporated Highland County?
Unincorporated Highland County does not issue residential building permits. No certified residential building department serves unincorporated Highland County, so no county residential building permit is issued there. 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 Highland County will issue you a permit.
Most likely yes. Deck construction or replacement usually requires a permit in Ohio. Confirm the specifics with Unincorporated Highland County.
Section 102.10 of the Residential Code of Ohio exempts from approval only a deck that is 200 square feet or less, not more than 30 inches above grade at any point, not attached to the dwelling, and not serving the required exit door. An attached deck, or any deck that misses one of those tests, needs approval. Ohio words 102.10 as an exemption from approval, not from the rules. An exempt deck must still comply with the rules of the Board of Building Standards. 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.
