Summary

Knoxville requires electrical work to pass staged inspections -- underground, rough-in, and final -- before any wiring can be covered, concealed, or connected to permanent power.

10.34.1 Inspection requests. It shall be the duty of the holder of the electrical permit or their duly authorized agent to notify the building official when work is ready for inspection. ... 10.34.3 Underground. Underground inspection shall be made after trenches or ditches are excavated and bedded, piping and conductors installed, and before backfill is put in place. ... 10.34.5 Final. Final inspection to be made after the building is complete, all electrical fixtures are in place and properly connected and the structure is ready for occupancy.

Full Breakdown

Permit holders must notify the building official when work is ready and provide access for each required inspection. Underground work is inspected after trenches are dug and conductors laid but before backfill. Rough-in inspection happens once framing, fireblocking, and wiring are complete but before insulation goes in -- all connections must be visible with junction box covers off. Final inspection comes once the building is finished, fixtures are connected, and the structure is ready for occupancy; on remodels, unused wiring and unsafe equipment must be disconnected first. No work can proceed past an inspection point until the building official signs off.

Violations & Fines

Covering or concealing wiring before the required inspection is approved is a code violation; the building official can order corrections and work must not proceed past that stage until authorized.

Frequently Asked Questions

What electrical inspections does Knoxville require?
Three staged inspections: underground (before backfill), rough-in (before insulation, with connections visible), and final (before occupancy, with fixtures connected and unused wiring removed).
Can I cover wiring before an inspector approves it?
No. Work found noncompliant must be corrected, and no portion can be covered or concealed until the building official authorizes it.
