The Kentucky rule
Kentucky's plumbing code is enforced statewide by the Division of Plumbing. Permits are generally required for installing or replacing water heaters, sewer and water service lines, new fixtures or drain lines (remodels and additions), and repipes. Like-for-like repairs — a faucet, a fill valve, clearing a drain — don't need one.
Lexington adds a layer for sewer
Anything touching the sanitary sewer in Lexington-Fayette — a new tap, a repair or replacement of the line to the main — also goes through the LFUCG Division of Water Quality, with its own application and inspection. Nicholasville sewer connections go through the city. We file both routinely.
What the inspection looks like
For a water heater, the inspector checks venting, connections, the relief valve and drain, the expansion tank and shut-off. For rough-in, they see the drains, vents and supplies under test before walls close. For sewer and water lines, they see the trench before it's backfilled. Passing the first time is a matter of doing it right, and it's how we do it.
Why it matters to you
A permitted, inspected job is documented — useful when you sell, useful for insurance, and proof the work meets code. A licensed plumber pulls the permit under his license, which means he's the one on the hook for it being right. If someone offers to skip the permit to save you money, that's who's saving money.
