King County, WA
25 psf
Ground snow load for ZIP 98022
ZIP 98022 straddles a county line. We have used King County, which holds most of it. If your address sits in the neighbouring county the figure may differ, and your building department can confirm which one you are in.
What this means for a shed
A shed rated below 25 psf is not rated for your county. A rating within 25% above it we report as marginal, because manufacturer ratings are self-declared and rarely account for drifting or unbalanced load.
This is informational, not engineering advice. Ground snow load varies with elevation and local amendment, and your local building department is the authority. Confirm with them before you buy.
