Set by local rules
Do you need a permit for Deck Construction in Clay County?
In South Dakota, there is no single statewide rule for a Deck Construction; whether you need a permit is decided locally in Clay 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 South Dakota leaves this to local jurisdictions, the reliable answer comes from Clay County Treasurer. Zoning setbacks apply either way.
