King County, WA
25 psf
Ground snow load for ZIP 98001
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.
