Municipal permitting reference

How building permits work in Louisville

Building permits in Louisville-Jefferson County are issued by the Department of Codes & Regulations (C&R) under the Kentucky Building Code (KBC, based on IBC). Since the 2003 city-county merger, a single permitting entity covers the entire metro. The Land Development Code (LDC) governs zoning; historic Preservation Districts (Old Louisville, Butchertown, Germantown) require Louisville Metro Planning Commission (LMPC) review. FEMA flood overlays are significant along the Ohio River and its tributaries. Permits are submitted through the Louisville ePermits portal.

Typical permitting sequence

  1. 1

    Verify zoning under the Land Development Code (LDC)

    Confirm the parcel's LDC zoning district and check whether it falls within a Preservation District (Old Louisville, Butchertown, Germantown, Smoketown, etc.) or a FEMA floodplain overlay (FP, FF, or FA zones along the Ohio River corridor, Beargrass Creek, and other waterways). Both overlays trigger additional review steps before building permits are issued.

  2. 2

    Louisville Metro Planning Commission (LMPC) approval if required

    Projects in designated Preservation Districts must obtain a Certificate of Appropriateness from the LMPC before C&R will issue a building permit for any exterior work. Conditional uses in any zoning district also require LMPC approval. Allow 4–8 weeks for the LMPC hearing cycle.

  3. 3

    Submit permit via Louisville ePermits portal

    Apply at the Louisville ePermits online portal with KBC-stamped (PE or architect) drawings, contractor license information, and any required flood compliance documentation (Elevation Certificate for FEMA Special Flood Hazard Areas). Pay intake and review fees at submission.

  4. 4

    Plans review by Codes & Regulations

    C&R reviewers check plans for KBC compliance (structural, accessibility, fire protection), LDC zoning compliance, and — for flood zone projects — floodplain management standards. The Louisville Fire Protection Review also occurs at this stage for commercial projects.

  5. 5

    Permit issuance

    Once all review disciplines approve the plans, pay remaining permit fees and receive the permit. Post the permit card on the job site; keep the approved plan set on site throughout construction.

  6. 6

    Staged inspections

    Schedule inspections online through the ePermits portal. Required stages: footing / foundation (including elevation inspection for flood zone projects), framing, rough-in MEP (electrical, plumbing, mechanical), insulation, and final.

  7. 7

    Certificate of Occupancy

    After a satisfactory final inspection, C&R issues the Certificate of Occupancy. The CO must be posted in the building before occupancy. For substantial improvements in a floodplain, a post-construction Elevation Certificate confirming compliance with the Flood Insurance Rate Map is typically required.

Common permit categories

  • • Building Permit (Residential)
  • • Building Permit (Commercial)
  • • Electrical
  • • Plumbing
  • • Mechanical
  • • Demolition
  • • ADU

Local considerations

  • • The 2003 Louisville-Jefferson County merger created a single metro-wide permitting authority — there is no separate city vs. county permit process.
  • • FEMA flood maps along the Ohio River, Beargrass Creek, and other tributaries require Elevation Certificates for new construction and trigger substantial-improvement calculations (50% rule).
  • • Historic Preservation Districts require LMPC Certificate of Appropriateness — even window replacements and siding changes on historic contributing structures.
  • • ADUs are permitted city-wide under the LDC; C&R reviews them on the residential building permit track.
