Deck building in Missouri

What Missouri homeowners should know before hiring a deck builder: contractor licensing, the building code, and how the climate affects materials.

How are deck contractors licensed in Missouri?

We could not confirm from an official Missouri source whether the state licenses or registers residential contractors, so treat your city or county building department as the authority: it issues deck permits and can tell you which contractor credentials it requires.

How do I check a Missouri contractor's license?

Ask your city or county building department about local contractor requirements, and call the Missouri Attorney General's consumer line at (800) 392-8222 to ask about complaints against a contractor.

Which building code applies to decks in Missouri?

We could not confirm a single statewide residential code edition for Missouri 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 Missouri climate mean for a deck?

Humid summers and wide temperature swings make wood move and finishes fail, and freeze-thaw winters push footings out of level. Tornadoes, hail, and severe storms are common, and termites are active across much of the state.
