Building a deck typically requires a permit if it is attached to the house, over 30 inches off the ground, or exceeds a certain square footage (often 200 sq ft).
Set by local rules
Do you need a permit for Deck Construction in Buchanan County?
In Missouri, there is no single statewide rule for a Deck Construction; whether you need a permit is decided locally in Buchanan County.
There is no single statewide building code, so the rule is set by your local jurisdiction; most still require a permit for any deck attached to the house or more than 30 inches above grade. Because Missouri leaves this to local jurisdictions, the reliable answer comes from Rural Buchanan County Zoning. Zoning setbacks apply either way.
