Do I need a permit for pergola or trellis in Unincorporated Adams County?

Unincorporated Adams County does not issue residential building permits. The Ohio Board of Building Standards (BBS) jurisdiction map lists no certified residential building department for Adams County, so no county residential building permit is issued for 1, 2 and 3 family dwellings in the unincorporated townships. BBS also lists no certified commercial department for the county. Township or county zoning permits and county health district septic and well permits may still apply.

The requirements below come from Ohio rules and describe the standard the work must still meet. They are not a statement that Unincorporated Adams County will issue you a permit.

Permit may be required

It depends. Whether pergola or trellis needs a permit in Unincorporated Adams County comes down to the details of your project.

Section 102.10 of the Residential Code of Ohio does not list pergolas, arbors, or trellises as work exempt from approval, so do not assume one is exempt. Ask the certified residential building department how it treats an open-roof structure. Attaching a pergola to the house, adding a solid or louvered roof, or adding wiring for lights or fans moves it closer to a patio cover and makes approval more likely. 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.
