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
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.
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 502-574-3321 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
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.

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.
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.
