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.

Project questions
Hardin County Planning & Development Commission / Kentucky Building Code Program 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 270-769-5479.
Commercial plan review goal: within 20 working days after submittal; large commercial projects may take longer. No separate residential review timeline was published.
Building and electrical permits must be submitted in person; the online portal is limited to certified electrical contractors registered with the office. After permit issuance, the owner or contractor must contact the office at 270-769-5479 or permits@hardincountyky.gov to schedule inspections. The published residential checklist covers footing, framing, and subsequent inspections; permits with no requested inspection for 180 days or more are deemed inactive and closed. Commercial plan review is targeted for return within 20 working days of complete submittal, with large projects potentially taking longer. On-site sewage evaluation is required before permits for dwellings or structures with plumbing; Hardin County Environmental Services is 270-769-0312.
The county’s residential packet identifies the 2018 Kentucky Residential Code; the commercial guide identifies the 2018 Kentucky Building Code based on the 2015 International Building Code with current Kentucky amendments. Building and electrical permits are required for new construction, additions, and remodeling; no newer 2026 KBC or KRC adoption was verified, and DHBC announced July 2026 NEC updates for electrical work. The county requires permits for new construction, additions, and remodeling, and its commercial guide requires permits for construction, enlargement, alteration, repair, moving, demolition, occupancy changes, and regulated electrical, gas, mechanical, or plumbing work. No broad cosmetic exemption list was published. Residential plan review is generally required for new single-family dwellings over 2,000 square feet of roofed area, while commercial projects require plan review; confirm any small accessory or maintenance project with the office.
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.
