Do I need a permit for shed or accessory structure in Unincorporated Robertson County?

It depends. Whether shed or accessory structure needs a permit in Unincorporated Robertson County comes down to the details of your project.

Kentucky does not require a building permit or inspection for a single-family dwelling unless the local government has passed an ordinance creating a residential inspection program (KRS 198B.060 and 815 KAR 7:125, Section 2(2)(a)), so the first question is whether the city or county covering the address has one. Where a local program exists, the Kentucky Residential Code (Section R105.2) exempts one-story detached storage sheds, playhouses, and similar structures of 200 square feet or less from a building permit; zoning setbacks can still apply. Wiring a shed of any size needs a state-required electrical permit and inspection (KRS 227.480). Farm buildings on a farm outside city limits that are not used for retail trade or as a regular workplace for 10 or more people are outside the state building code (KRS 198B.010). A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured.
