Deck Construction · Jefferson County, Kentucky
In Jefferson County, a Deck Construction under 200 sq ft generally does not require a building permit. At or above 200 sq ft, a permit is required.
A deck under 200 square feet, not more than 30 inches above grade, not attached to a dwelling, and not serving a required exit door is exempt from a building permit throughout Jefferson County. Because Kentucky enforces a mandatory statewide mini/maxi code, no local government may adopt a different threshold; several small cities within Louisville Metro that lack expanded construction jurisdiction coordinate directly with the county's Office of Construction Review rather than reviewing plans independently. Building permits in Jefferson County are handled under the Louisville Metro Government, Office of Construction Review ( building code (IRC Kentucky Building Co). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Permits & Licensing.
