Summary
Toledo publishes a frost line depth of 36 inches minimum in a Toledo-specific design criteria table issued by its Division of Building Inspection.
CITY OF TOLEDO Division of Building Inspection. The Residential Code of Ohio (RCO) for One-, Two- and Three-Family Dwellings, 2013 Edition, is used for all residential construction of the same occupancy. RCO Table 301.2(1) CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA (TOLEDO, OHIO): Ground Snow Load (lbs/sf) 20; Frost Line Depth (b) 36" min; Wind Speed 90; Seismic A or B; Weathering Severe.

Full Breakdown
Ohio leaves frost line depth to each jurisdiction, and Toledo answers it in a construction procedures sheet from the Division of Building Inspection. That sheet embeds a table captioned for Toledo specifically and gives a frost line depth of 36 inches minimum. At 36 inches Toledo is deeper than Columbus at 32 and Dayton at 32, which is what you would expect for the northwest corner of the state. The same table records weathering as Severe, a wind speed of 90 and a seismic design category of A or B. One important caveat: the sheet states that it works from the 2013 edition of the Residential Code of Ohio, and it was last revised in January 2018. Ohio's current residential rule dates from 2019, so this document is two editions behind and the figure is worth confirming with the division before it drives a design.
Violations & Fines
Footing depth is verified at inspection before concrete is placed. A footing above 36 inches will not pass. Because the governing document is a departmental procedures sheet rather than codified ordinance, it is what plan reviewers work from, and because it is keyed to a superseded code edition, confirming currency with the Division of Building Inspection is the sensible step on anything substantial.
