Business licenses and permits in Louisville/Jefferson County, Kentucky
A consolidated city-county government (merged 2003), like Nashville and Indianapolis. Its central local requirement is not a flat business license but the Revenue Commission's occupational license tax — 2.20% of wages/net profit for residents and business entities, 1.45% for non-resident individuals. Fire protection is genuinely fragmented across roughly a dozen independent fire protection districts plus the Louisville Division of Fire, which covers only the historic Urban Services District — no single Metro-wide fire inspection fee applies.
What are you opening in Louisville/Jefferson County?
- RestaurantsFull-service restaurants carry the densest permit load of any small business: food, fire, occupancy, waste, and usually alcohol.See the full permit list
- Coffee shopsCafés are permitted as food service establishments even where no cooking happens, and the plan review step catches most operators by surprise.See the full permit list
- Retail storesRetail is the lightest common permit load, but the sales tax permit and the certificate of occupancy are non-negotiable in every jurisdiction.See the full permit list
- Salons and barbersPersonal care is licensed at state board level as well as locally, so the shop license and the practitioner licenses are separate obligations.See the full permit list
- Food trucksMobile food is the one category with no certificate of occupancy — but it gains a commissary agreement, and the unit itself is inspected rather than the premises.See the full permit list
- Fitness studiosPrepaid memberships trigger state registration and often a surety bond, which catches operators who budgeted only for the fit-out.See the full permit list
- Childcare centresThe heaviest permit load of any small business: state agency licensing, per-person background checks, and a stricter fire standard than ordinary commercial use.See the full permit list
- Contractors and tradesLicensed at state board level rather than locally, and the only common category with no premises permits at all — the bond is usually the long pole.See the full permit list
- Auto repair shopsOrdinary commercial permitting plus an environmental layer: waste oil, solvents and stormwater are each registered separately.See the full permit list
- Veterinary clinicsA state facility permit, controlled substances registration at both state and federal level, and a medical waste manifest — none of which a general business license covers.See the full permit list
Permits that apply to every type of business in Louisville/Jefferson County
| Permit | Issuing agency | Fee | Renews | Last checked |
|---|---|---|---|---|
| Commercial Building Permit | Louisville Metro Department of Codes & Regulations, Office of Construction Review | Calculated per square foot by Kentucky Building Code occupancy type: Assembly and High Hazard $0.16/sq ft; Business, Institutional, Mercantile, and Residential (other than 1-2 family) $0.15/sq ft; Educational and Factory $0.14/sq ft (Storage is also $0.14/sq ft); Utility/Miscellaneous $0.13/sq ft; Residential 1-2 Family $0.105/sq ft.

Work whose cost cannot be calculated by square footage is billed at $50 plus $2.50 per $1,000 of the applicant's estimated cost. | one-time, per project | 2026-09-09 |

| Occupational License Tax Registration | Louisville/Jefferson County Metro Revenue Commission | 1.25% (Metro Government) + 0.20% (Transit Authority of River City) + 0.75% (Jefferson County/Anchorage school boards) = 2.20% total, applied to both (a) wages and compensation paid to employees for work performed in Louisville Metro and (b) the net profit of a business entity or resident individual conducting business there. A non-resident individual (a non-resident sole proprietor or employee) pays only the Metro and TARC components — 1.45% — because non-resident individuals are exempt from the school board component by statute. There is no minimum tax, and applying for the account number itself carries no separate fee. | annual — the net profit return (Form OL-3) is due the 15th day of the 4th month after the fiscal year ends (April 15 for calendar-year filers); employers withhold and remit the wage portion quarterly | 2026-09-09 |

What do these permits involve in Louisville/Jefferson County?
Commercial Building Permit
Electrical, HVAC/mechanical, and fire suppression/detection work are permitted and fee'd separately under the same chapter — see the standalone Fire Suppression/Detection Permit record for that portion.
Certificate of Use and Occupancy
Where a building permit is already being issued for the same project, the occupancy sign-off appears to be part of that permit's inspection process rather than separately billed at $75 — the fee document does not state this explicitly for the combined case.
Fire Suppression/Detection System Installation Permit
This is the Office of Construction Review's Metro-wide installation permit, not an ongoing fire-code inspection fee. Jefferson County's ongoing fire code enforcement and inspections are split across roughly a dozen independent fire protection districts plus the Louisville Division of Fire (which covers only the historic Urban Services District) — no single, Metro-wide recurring inspection fee could be confirmed, and none is asserted here.
Occupational License Tax Registration
This is Kentucky's local occupational tax, not a flat business license fee — it is levied on nearly every business, trade, profession, or activity for profit conducted in Louisville Metro (all of Jefferson County), regardless of the entity's legal residence. A $25 minimum PENALTY applies only for failing to file a return by the due date, regardless of whether tax is owed — that is not a registration fee and is not what is recorded above.
Zoning Confirmation / Zoning Certification Letter
The Louisville Metro Office of Planning fee schedule (Land Development Code Appendix 11B, in effect July 1, 2025) prices a Zoning Confirmation and a Zoning Certification Letter but does not say whether either is a mandatory prerequisite for a given business type or an optional due-diligence document; contact the Office of Planning for that. Several other requirements listed for Louisville (the Conditional Use Permit for child care, for example) separately depend on a zoning determination.
