Deck Building and local data in King County
Footing depth is the first local question. The Seattle Sand Pt Wsfo weather station records about 25 nights a year at or below freezing for in King County's covered ZIP codes, so footings must reach the frost depth the building department sets, and about 3.8 inches of yearly snowfall feeds into beam and joist sizing.
49% of the 967,427 homes in King County's covered ZIP codes are detached houses and 6% are townhouses or other attached homes, which sets the mix between open backyard decks and compact elevated ones; with a median build year of 1983, most new decks bolt to a modern rim joist behind proper flashing.
About 2 days a year reach 90°F, so orientation, shade and board color are design decisions in King County's covered ZIP codes, not afterthoughts.
