Municipal permitting reference

How building permits work in Knoxville

Knoxville building permits are issued by the Department of Community Development's Building Codes Enforcement Division under the Tennessee Building Code (2018 IBC/IRC as adopted by the state). Knox County handles unincorporated areas under a separate system. The Knoxville Metropolitan Planning Commission (MPC) reviews rezonings and subdivisions. Downtown Design Districts (D-1 through D-4) and the South Waterfront development area have design guidelines. Trade permits (electrical, plumbing, HVAC) are issued separately through state-licensed inspectors. Applications are submitted via the KnoxPlanit online portal.

Typical permitting sequence

  1. 1

    Verify zoning under the Knoxville Zoning Ordinance

    Confirm the parcel's zoning district and check whether it falls within a Downtown Design District (D-1 through D-4), the South Waterfront development area, or the Urban Wilderness adjacent areas, each of which has design guidelines that affect exterior appearance. If the proposed use is not permitted by-right, a rezoning petition to the MPC is required.

  2. 2

    MPC staff review for rezonings and subdivisions

    If the project requires a rezoning, special use permit, or subdivision plat, file with the Knoxville Metropolitan Planning Commission (MPC). MPC staff reviews the application, issues a recommendation, and schedules a public hearing before the MPC Board. The full rezoning cycle typically takes 60–90 days. The MPC also reviews Downtown Design District projects for design guideline compliance.

  3. 3

    Submit building permit via KnoxPlanit portal

    Apply through the KnoxPlanit online portal with Tennessee-stamped (PE or architect) drawings, energy compliance documentation, contractor license information (Tennessee requires state-licensed contractors), and any MPC approvals. For projects in Downtown Design Districts, include design guideline compliance materials.

  4. 4

    Plans review by Building Codes Enforcement

    City reviewers check plans for Tennessee Building Code compliance (structural, fire protection, accessibility), zoning ordinance compliance, and energy code. Downtown Design District projects receive concurrent design review. Correction letters are issued through KnoxPlanit.

  5. 5

    Permit issuance

    Once all reviewers approve the plans, pay permit fees (based on project valuation). Post the building permit card visibly on the job site. A complete set of approved plans must remain on site throughout construction.

  6. 6

    Staged inspections — city and state-licensed trade inspectors

    Structural inspections (foundation, framing, insulation, final) are performed by City of Knoxville Building Codes inspectors — scheduled through KnoxPlanit. Trade inspections (electrical, plumbing, HVAC/mechanical) are performed separately by state-licensed inspectors under the Tennessee Contractor Licensing Board programs. Coordinate both tracks to avoid delays.

  7. 7

    Certificate of Occupancy or Certificate of Completion

    After all city structural inspections and state trade inspections are complete, the Building Codes Enforcement Division issues a Certificate of Occupancy (new buildings / change of occupancy) or Certificate of Completion (alterations). Both the city and trade inspection sign-offs must be on file before the CO is issued.

  • • HVAC/Mechanical (Trade)
  • • Demolition
  • • Sign

Local considerations

  • • Knox County handles permits for unincorporated areas — confirm which jurisdiction applies before submitting; the city/county boundary is not always intuitive.
  • • Tennessee's state-licensed inspector system for electrical, plumbing, and HVAC means trade permits follow a parallel track — start both tracks simultaneously to avoid sequential delays.
  • • The Downtown Design Districts (D-1 through D-4) have detailed design guidelines for building facades, streetscapes, and signage — review guidelines with MPC staff before schematic design.
  • • The South Waterfront and Knoxville Urban Wilderness areas are active development corridors with ongoing planning overlays — check with MPC for current guidelines.
