Deck Stairs and local data in Illinois
Stair landings and stringer bases sit low and stay wet; with about 121 freezing nights a year in our covered Illinois ZIP codes, a concrete landing or footing at the bottom of the stringers keeps stairs from heaving.
About 42.3 inches of snow a year makes slip-resistant treads and a graspable handrail especially important on exterior stairs.
Homes here have a median build year of 1975; stairs on older decks often predate today's consistent riser and tread limits and are commonly rebuilt during other deck work.

Who issues permits for deck stairs in Illinois?
Illinois permits come from the city or county building department; new or structural work usually needs a permit. Contractor licensing and code details for Illinois are on our Illinois page.
When is the best time for deck stairs in Illinois?
Average lows near Illinois stay above freezing from April–November, which is the main building window. For staining and sealing wood, the best-balanced months are April, July and September–October.
The coldest month is January (average low 19°F) and the hottest is July (average high 85°F). May is typically the wettest month, with about 4.5 inches of precipitation — plan finish work around it. January brings the most snow on average (about 11.3 inches), so footings and framing are best finished well before then. Use the winter months to settle the design and apply for permits, so footings can go in as soon as the ground allows.
