Do I need a permit for basement finishing in Unincorporated Monroe County?
Unincorporated Monroe County does not issue residential building permits. Monroe County has no Ohio Board of Building Standards certified residential building department (BBS jurisdiction map and certification list), so no county residential building permit is issued for 1-, 2- and 3-family homes in unincorporated areas. Washington County Building Department (205 Putnam St, Marietta, 740-374-4185) is the certified commercial department for Monroe County. Township zoning permits (where a township has zoning), floodplain permits, and county health district septic and well permits may still apply. Some cities and villages in the county run their own departments.
The requirements below come from Ohio rules and describe the standard the work must still meet. They are not a statement that Unincorporated Monroe County will issue you a permit.
Most likely yes. Basement finishing usually requires a permit in Ohio. Confirm the specifics with Unincorporated Monroe County.
Under Section 310.6 of the Residential Code of Ohio an escape opening is not required when an existing basement is altered, but every new sleeping room created in a basement needs an emergency escape and rescue opening. Where alterations needing approval reach sleeping areas or add a sleeping room, Section 314.2.2 requires smoke alarms in those areas, and Section 315.2.2 requires carbon monoxide alarms in homes with fuel-fired appliances or an attached garage. New wiring, plumbing, or ductwork needs approval under Section 105.1, and new building envelope work must meet the energy chapter (Section 1109). 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.
