Summary
Dayton makes it unlawful to build, alter, remove or demolish any building or structure, or change its use, without first filing a written application and obtaining a permit from the Building Official.
It shall be unlawful to construct, alter, remove, or demolish any building or structure, or part thereof, or change the use or occupancy thereof, or to install or alter any equipment for which provision is made or the installation of which is regulated by this code, without the owner or the owner's agent first filing an application with the building official in writing and obtaining the required permit therefor, except for work exempt from approval, as defined in the OBC, which does not involve any violation of the UBC, shall be exempt from this provision. Except as specifically otherwise authorized, application for a permit for any work requiring a permit shall be submitted to and approved by the building official before any contract for installation or construction of the proposed work has been awarded, unless such award is made contingent on the approval and issuance of the permit.

Full Breakdown
R.C.G.O. §153.07 makes it unlawful to construct, alter, remove or demolish any building or structure, or change its use or occupancy, without first filing a written application with the Building Official and obtaining a permit: work exempt from approval under the state Ohio Building Code is the only carve-out. A homeowner may do the work themselves on their own single-family residence without a contractor's license, but every permit, inspection and approval the Code requires still applies. An unfiled or unapproved application is deemed abandoned six months after filing unless the Building Official grants an extension of up to 90 days at a time.
Violations & Fines
Building without the required permit exposes the project to a stop-work order, permit revocation, and misdemeanor prosecution, with each day of continued unpermitted work counted as a separate offense.
