How are deck contractors licensed in Michigan?
Michigan's Department of Licensing and Regulatory Affairs (LARA), through its Bureau of Construction Codes, licenses residential builders and maintenance and alteration contractors who build or repair homes and their additions. Building permits come from the local building department or, where there is none, from the state. Note that LARA reported a 2025 court order kept the 2015 IRC-based residential code in effect while a 2021 update was in litigation, so confirm the current code locally.
How do I check a Michigan contractor's license?
Use LARA's 'Find / Verify a BCC Licensed Professional or Business' search.
Which building code applies to decks in Michigan?
We could not confirm a single statewide residential code edition for Michigan from an official source, so ask your city or county building department which edition it enforces before plans are drawn.
Most U.S. deck rules trace back to the International Residential Code and the American Wood Council's DCA 6 guide: footings below the local frost line, a properly flashed and bolted ledger, guards on decks more than 30 inches above grade, and stair dimensions within code limits.
What does the Michigan climate mean for a deck?
Lake-effect snow, especially on the west side and in the Upper Peninsula, puts serious weight on decks, and deep frost requires properly set footings. Humid summers and frequent freeze-thaw cycles accelerate rot and fastener loosening.
