Do I need a permit for addition or structural alteration in Lexington?
Most likely yes. Addition or structural alteration usually requires a permit in Kentucky. Confirm the specifics with Lexington.
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. Even without a local building program, new wiring needs a state-required electrical permit, added or moved plumbing needs a plumbing permit, and an addition with its own new HVAC system needs a state HVAC permit (KRS 227.480, 815 KAR 20:050, 815 KAR 8:070). Local governments may not adopt any building code for one- and two-family dwellings other than the Kentucky Residential Code (KRC R101.3). Kentucky has no statewide dollar-value exemption from permits.
Local detail for Lexington: Lexington and Fayette County have a merged urban county government, which issues building permits for the whole county.
