Full Breakdown
Ohio's residential code deliberately leaves the frost line depth column empty and directs each jurisdiction to fill it in, and Dublin is one of the few central Ohio suburbs that publishes a formal answer. Its residential permit packet carries a City of Dublin Amendments block that completes Table 301.2(1), and the frost line depth entry reads 36 inches. The figure is corroborated independently in the city's deck packet, whose footing detail legend calls for a footing a minimum of 36 inches below grade: useful confirmation, because decks are the most common reason a homeowner needs this number. Note the edition: the amendment block completes the table of the 2013 Residential Code of Ohio, while the state's current residential rule dates from 2019, so the published document is keyed to a superseded edition even though the depth itself is restated in the city's current deck guidance.
Violations & Fines
Footing depth is verified at inspection before concrete is placed. Dublin's deck packet makes the trigger explicit for the most common case, requiring the footing inspection at clean, dry holes before concrete. A footing bearing above 36 inches will not pass. Dublin operates its own state-certified building division rather than deferring to Franklin County, so this figure is enforced by the city.
