Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
Commercial plan review goal: within 20 working days after submittal; large commercial projects may take longer. No separate residential review timeline was published.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 270-769-5479 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
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
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.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
