Kentucky permits
Do you need a permit in Kentucky?
Kentucky enforces the Kentucky Residential Code (IRC-based) statewide through the Department of Housing, Buildings and Construction. Permits are issued by local building departments. Kentucky licenses electrical and HVAC contractors at the state level; plumbing is state-licensed. There is no statewide GC license for general residential work.

Can a homeowner pull the permit?
Yes, in most cases. Owner-occupied primary residences. Plumbing/HVAC generally require licensed professionals on covered work.
Where to file: Local building department or the state for jurisdictions without one. Louisville (Develop Louisville), Lexington have portals. Plan review 1-2 weeks. Statewide code keeps rules consistent.
