What are your local climatic design criteria for structural design? Commercial Criteria: Frost Depth = 32"; Ground Snow Load = 20 PSF; Wind Speed = 90 MPH; Seismic Zone = 1. Residential Criteria: Frost Depth = 32"; Ground Snow Load = 20 PSF; Wind Speed = 90 MPH.
Full Breakdown
Montgomery County's Building Regulations Division states its climatic design criteria in a single FAQ answer, and gives 20 PSF as the ground snow load for both residential and commercial work. Twenty psf is the common figure across central and western Ohio, Columbus, Dublin, Toledo and Lucas County all adopt it, and stands in contrast to Cleveland's 30 psf on the Lake Erie snow belt. Because the division's jurisdiction covers every township in the county plus the villages and cities that contract with it, this figure governs a substantial share of Montgomery County by area, not merely unincorporated land. The commercial criteria add a seismic zone of 1, which the residential entry omits. As with the frost depth, the 90 MPH wind speed and the absence of a named code edition suggest a document written before the 2019 Residential Code of Ohio.
Violations & Fines
Ground snow load is a design input checked at plan review rather than a citable offence. Drawings must show the structure designed for 20 psf, with the roof value derived under the normal code provisions. Confirm first whether the county or a municipal department reviews your project, since that determines whose criteria apply.
