Deck Construction Permits in Dayton
Local Rule
City of Dayton Building Inspection Division
Dayton enforces the Residential Code of Ohio, which exempts a deck from a building permit only when it is 200 square feet or smaller, no more than 30 inches above grade at any point, not attached to the dwelling and does not serve the required exit door, so most attached decks fail the exemption and need a permit regardless of size. The city's own fee document sets a minimum building permit fee of $43.64, with fees above that calculated as 1 percent of project value over $2,000 plus that base amount, before adding the separate State of Ohio surcharge; a permit expires one year after issuance or the last inspection date. Minimum footing depth in Dayton is 32 inches, and an owner who occupies or will occupy a single-family residence may perform the permitted work themselves under Sec. 153.07(A) of the Dayton Code of Ordinances.

How This Compares to Montgomery County
Dayton's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:
Montgomery County Building Regulations / City of Dayton
Montgomery County (Dayton), the OHIO Montgomery County, not the Maryland one, regulates residential decks through its Building Regulations Division (451 W. Third St., Dayton) for all townships and for cities that contract with it; the City of Dayton runs its own Building Inspection Division, as do Kettering, Centerville, and others. Under the 2019 Residential Code of Ohio, a building permit is required for any deck 24 inches or more above grade (treated as a building addition), and the county publishes "Residential Deck Details" that may be used in lieu of construction plans for single-span, single-level decks without roofs, screened porches, or hot tubs.
