Do I need a permit for addition or structural alteration in Unincorporated Erie County?
Unincorporated Erie County does not issue residential building permits. The Ohio Board of Building Standards (BBS) jurisdiction map lists no certified residential building department for Erie County, so no county residential building permit is issued for 1, 2 and 3 family dwellings in the unincorporated townships. Exception: BBS lists certified residential departments for some townships: Huron Township (also serving Groton and Oxford townships), 1820 Bogart Rd, Huron, 419-433-2755; Perkins Township, 2610 Columbus Ave, Sandusky, 419-609-1435; and Vermilion Township, 1907 State Rd, Vermilion, 440-204-2410. 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 Erie County will issue you a permit.
Yes. In Ohio, addition or structural alteration generally requires a permit, and Unincorporated Erie County is no exception.
Under the Residential Code of Ohio, enlarging or structurally altering a dwelling requires a permit and is never covered by the minor-repair exemption. An addition can trigger separate zoning, setback, or floodplain review in addition to the building permit; confirm requirements with your local department early.
