Do You Need a Permit for a Pool in Louisville?
For an in-ground pool, yes. Louisville Metro's Construction Review issues residential pool permits under the Pool/Spa - Residential record type in its online portal, and the Kentucky Residential Code (KRC) defines a private swimming pool as one holding water over 24 inches deep. Kentucky treats above-ground pools differently from the national model code: its definition of a building includes swimming pools constructed below grade on site, but not pools assembled above grade, and the KRC's scope section lists swimming pools constructed completely above grade as an exception. That points to no building permit for a typical above-ground pool. The pump circuit is a separate matter: new wiring or a new receptacle needs a Metro electrical permit. Construction Review's in-ground pool guide was unreachable for this article, so confirm both points before you buy.
Louisville Pool Permit Rules by Scenario
| What you are doing | City filing | Rule |
|---|---|---|
| In-ground pool deeper than 24 in | Building permit (Pool/Spa - Residential) plus electrical | KRC definitions; LMCO 150.096 |

How Much Does a Pool Permit Cost in Louisville?
Metro's promulgated fee schedule (LMCO 150.096, revised February 6, 2024) prices structures other than buildings by estimated cost: $50 plus $2.50 per $1,000, with a $75 minimum. A $40,000 in-ground pool pays $50 + $100 = $150. An $80,000 pool pays $50 + $200 = $250, and with a $100 electrical permit for the pump and lighting circuit (work over $750) the total is $350. Each extra electrical inspection beyond the one included costs $50. If a permit expires before the final inspection, reactivating it within 180 days costs $35.
Barrier and Location Rules
Kentucky's Section R326.8.1 requires a barrier around an outdoor in-ground pool whose top is at least 48 inches above grade on the side away from the pool, with no opening that passes a 4-inch sphere and no more than 4 inches of clearance at the bottom. Pedestrian gates must open outward, away from the pool, and be self-closing and self-latching. The Land Development Code adds that fences and walls required for swimming pools must be at least 4 feet high with a self-closing, self-latching lockable gate. Section R326.9 keeps the pool wall 6 feet from rear and side property lines and 10 feet from a street property line, unless the jurisdiction's own rules say otherwise. In a designated floodway you must also document that the pool will not raise the design flood elevation.
Who Does the Work?
Electrical work must be done by a licensed electrical contractor unless you are a homeowner wiring your own home under Metro's notarized homeowner certification. Construction Review takes contractor permits in the Louisville Metro Business Portal; call (502) 574-3321 for an owner-filed pool permit.
