Deck Installation and local data in Illinois
Footing depth is the first local question. The Chicago Ohare Intl. AP weather station records about 121 nights a year at or below freezing for in our covered Illinois ZIP codes, so footings must reach the frost depth the building department sets, and about 42.3 inches of yearly snowfall feeds into beam and joist sizing.
59% of the 1,249,514 homes in our covered Illinois ZIP codes are detached houses and 10% are townhouses or other attached homes, which sets the mix between open backyard decks and compact elevated ones; with a median build year of 1975, most new decks bolt to a modern rim joist behind proper flashing.
With rain or snow on about 76 days a year, installation details that move water away — joist tape, ledger flashing and correct board gaps — matter more in our covered Illinois ZIP codes than the board brand.
