Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Louisville Metro Government, Department of Codes & Regulations, Office of Construction Review is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 502-574-3321.
No general plan-review timeline was published. Simplified residential rooftop-solar building permits are generally turned around in three days or less when the application package is complete and compliant; other projects depend on review complexity and revisions.
The permit holder must request inspections when the work is ready, generally through the Louisville Metro Business Portal; by phone call 502-574-3321, option 2, for building, HVAC, or miscellaneous inspections. Provide the permit number, complete job-site address and ZIP code, contact information, desired inspection, and access instructions. Common building inspections are foundation, rough framing/rough-in, and final; work must remain accessible and uncovered, and all required inspections must pass before a Certificate of Occupancy or Letter of Acceptance. Electrical requests use the contractor portal, except an owner with their own residential electrical permit may use option 2. Reinspection fees may apply.
Louisville Metro Ordinance §150.001 adopts the Kentucky Building Code and Kentucky Residential Code in full. The applicable framework is the 2018 KBC and 2018 KRC, based on the 2015 IBC/IRC with Kentucky amendments. No newer 2026 KBC or KRC adoption was verified; electrical work remains subject to the applicable Kentucky electrical standards and Louisville Metro inspection requirements. Examples of work listed by Louisville Metro as exempt include one-story detached sheds, playhouses, or storage buildings under 200 square feet; fences up to 7 feet; retaining walls up to 4 feet; grade-supported water tanks up to 5,000 gallons with the stated height-to-width limit; sidewalks and driveways; painting, papering, tiling, carpeting, cabinets, countertops and similar finish work; swings/playground equipment; qualifying wall-supported window awnings; and unattached ground-level decks up to 200 square feet and 30 inches high that do not serve a required exit. Electrical exemptions include listed temporary decorative lighting, same-location overcurrent-device replacement, under-25-volt/50-watt systems, minor repairs, and temporary testing systems. Gas, mechanical, and plumbing exemptions cover portable equipment and limited repairs such as stopping leaks or clearing stoppages; confirm the full code conditions before relying on an exemption.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
