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
At least two days for plan review; the county says some plans may require additional time.
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 865-397-0640 (Building Department); 865-397-4414 (Zoning Department); 865-397-2155 (Highway Department driveway permit) 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
Jefferson County Building Department 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 865-397-0640 (Building Department); 865-397-4414 (Zoning Department); 865-397-2155 (Highway Department driveway permit).
At least two days for plan review; the county says some plans may require additional time.
Submit two copies of plans, blueprints, or drawings to the Building Department; plan review has a required two-day waiting period, although complex plans may take longer. The county procedure also requires the deed, plat/survey, septic approval, and a driveway permit from the Highway Department. The Building Department handles review and inspection questions at 865-397-0640.
Jefferson County states that it has adopted the 2018 International Residential Code. The county Building Department reviews residential plans for compliance with adopted construction codes, zoning regulations, and safety standards; a separate current commercial-code edition was not identified in the county’s published materials. A permit is required for garages, new buildings, and additions, including any new nonportable structure or addition to an existing structure. Structures used strictly for agricultural purposes and portable structures are excluded from that stated requirement. Ordinary maintenance or repair and agricultural buildings are also described as exempt in the county zoning resolution; confirm borderline projects with Building or Zoning.
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.
