Roofing in Miamisburg, Ohio

The Residential Code of Ohio (RCO), Ohio Administrative Code Division 4101:8, adopted by the Ohio Board of Building Standards, governs one-, two- and three-family dwellings statewide; its roof assemblies rule (OAC 4101:8-9-01) and administration rule (OAC 4101:8-1-01) carry an effective date of July 1, 2019. Ohio Rev. Code 3781.01(B) provides that the state residential building code "does not prevent a local governing authority from adopting additional regulations governing residential structures that do not conflict with the state residential building code". Under RCO 101.5, where no building department certified by the Board of Building Standards for residential buildings has jurisdiction, "the owner is not required to make submission of construction documents, seek approvals, request inspections, or obtain certificates of occupancy". In Miamisburg, the Development Department's building inspection function is responsible for construction inspection and issuance of all permits (except for plumbing permits) pertaining to building improvements and construction activity. Its page states that "The city of Miamisburg's Building Department is certified by the Ohio Board of Building Standards to regulate the construction of both commercial and residential structures including electrical, fuel gas piping and HVAC systems." This record did not read Miamisburg's own codified ordinances, so any additional local building regulation is not reflected here.
