Building Permits in Knoxville

The City of Knoxville Development Services permit system handles city construction permits and publishes the construction codes currently in effect. Projects outside Knoxville city limits may fall under a different authority, including Knox County, so confirm jurisdiction first.

Current Construction Codes

Knoxville's official Construction Codes page lists the 2024 International Building Code among the city's current codes. It also lists the 2023 electrical code (NFPA 70) and the 2018 Energy Conservation Code, along with other adopted construction and fire codes. Use the city's current code page and adopting ordinances because different code families may have different edition years.

Permit Process

  1. Confirm the project is within Knoxville city limits and check zoning requirements.
  2. Identify the correct building and trade permits.
  3. Make sure the permit holder has the license or city registration required for that permit type.
  4. Submit the application and required plans through the city's permit system.
  5. Complete plan review and respond to corrections.
  6. Pay applicable fees and obtain the permit.
  7. Request required inspections as work progresses.
  8. Complete final approval and any occupancy documentation applicable to the project.

Licensing and Registration

Knoxville's permit system requires an appropriate licensed or registered individual to be associated with permits. The city expressly notes that this does not mean every permit requires a State of Tennessee licensed contractor. Different permit-holder license and registration types have different requirements, so verify the category for the work.

Fees and Review Time

Fees depend on permit type and scope. Use the city's current fee information for the application. No unsupported general review-time range is stated here.

Inspections

Required inspections depend on the permit and approved work. Use the city's project-specific inspection instructions and do not assume the same sequence applies to every permit.

Architects and Engineers

Tennessee law and project scope determine when professional design and sealed documents are required. Confirm the rule for the specific project rather than applying a universal seal requirement.
