Deck Building and local data in Minnesota
Footing depth is the first local question. The Lower St Anthony Falls weather station records about 147 nights a year at or below freezing for in our covered Minnesota ZIP codes, so footings must reach the frost depth the building department sets, and about 40.4 inches of yearly snowfall feeds into beam and joist sizing.
57% of the 1,323,901 homes in our covered Minnesota ZIP codes are detached houses and 11% are townhouses or other attached homes, which sets the mix between open backyard decks and compact elevated ones; with a median build year of 1979, most new decks bolt to a modern rim joist behind proper flashing.
About 18 days a year reach 90°F, so orientation, shade and board color are design decisions in our covered Minnesota ZIP codes, not afterthoughts.
