Shed Installation · Montgomery County, Ohio
In Ohio, whether a Shed Installation needs a permit depends on the scope of the work.
A detached, one-story shed 200 sq ft or less does not require a residential building permit, though a Zoning Permit is still required. Distinctively, Montgomery County administers the residential building-code appeals board, while the City of Dayton separately administers the commercial appeals board, a split by property type rather than by geography. Confirm which permits your project triggers with Montgomery County Building Reg.
