Summary
Columbus adopts a ground snow load of 20 pounds per square foot, the figure Ohio's code leaves for each jurisdiction to supply.
Table R301.2(1) CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA: Ground Snow Load (e) 20; Wind Speed (mph) 90; Seismic Design Category B; Weathering (a) Severe; Frost Line Depth (b) 32"; Ice Shield Underlayment Required Yes; Flood Hazards See Flood Insurance Rate Maps; Air Freezing Index 1048; Mean Annual Temp 52.6.
Full Breakdown
The Residential Code of Ohio leaves the ground snow load column blank and directs the jurisdiction to fill it in, and Columbus supplies 20 psf in Construction Industry Communication #09. That is a light design load by national standards, Massachusetts towns run from 25 to 60 psf and Indiana's northern counties carry 30 psf, and it reflects central Ohio's snowfall rather than a relaxed standard. It matches the figures Dublin and Toledo publish, so the central and northwest Ohio cities we cover cluster at the same value even though their frost depths differ. The same table requires ice shield underlayment, which applies regardless of how modest the snow load is, and records the air freezing index as 1048.
Violations & Fines
Ground snow load is a design input checked at plan review rather than a citable offence. Structural drawings submitted with a building permit must show the roof designed for the adopted figure, with the roof value derived from it under the normal code provisions. The separately required ice shield underlayment is inspected as part of the roofing work.
