Summary
Before building a shed or any other accessory structure in Dayton, the zoning code requires a zoning certificate from the Zoning Administrator: there's no size-based exemption in the local text.
The construction, building, moving, remodeling, or reconstruction of any building or structure shall not be commenced; ... the use of land, buildings or structures for temporary and accessory uses shall not be commenced; ... unless a zoning certificate shall first have been obtained from the Zoning Administrator.
Full Breakdown
Section 150.135.1 of Dayton's Zoning Code bars commencing construction of any building or structure, including 'temporary and accessory uses,' until a zoning certificate is obtained from the Zoning Administrator. For an accessory structure like a shed, the application is reviewed under § 150.135.3 alongside the principal dwelling's plot plan; the Administrator has up to 30 days after a complete application to approve or deny it, and an issued certificate is valid for 12 months. This zoning certificate is separate from any building permit that may apply under the state-adopted Ohio Residential Code (§ 153.07); Dayton's own zoning text sets no minimum shed size below which a certificate isn't needed.
Violations & Fines
Building a shed without a zoning certificate draws an enforcement fee up to the certificate's cost, capped at $2,000 under Schedule 150.130.10, plus a possible minor-misdemeanor citation.
