Summary

Aurora's Electrical Code requires the building official to inspect underground work before backfilling and rough-in wiring before walls or ceilings close it up.

106.1 General. The building official, upon notification, shall make the inspections set forth in this section. 106.2 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. 106.3 Rough-in. Rough-in inspection shall be made after the roof, framing, fireblocking and bracing are in place and all wiring and other components to be concealed are complete, and prior to the installation of wall or ceiling membranes.

Full Breakdown

Under the city's Electrical Code administrative provisions (Sec. 12-31), the building official must perform the inspections set out in Section 106 upon notification. Underground inspection happens after trenches are excavated, bedded, and wired but before backfill; rough-in inspection happens after framing and concealed wiring are complete but before wall or ceiling coverings go up: a two-stage checkpoint system that keeps concealed work verifiable before it's covered.

Violations & Fines

Covering underground or rough-in electrical work before the required inspection is completed is a code violation; the building official can require the work uncovered for inspection.

Frequently Asked Questions

No: rough-in inspection must happen after wiring is complete but before wall or ceiling membranes are installed, per § 106.3.
