ELECTRICAL ROUGH-IN and FINAL
When a home is built, an addition added or a during a major remodel, there will be a rough in phase for the different trades. In the electrical trade the rough in occurs after the framing has been completed but before the drywall has gone up. This is during the “wet phase” of construction where natural elements are exposed to the build (meaing that rain and moisture will be exposed to the items in the build). It is the time when access to the space between the studs, floor joists, ceiling joists and every other nook and cranny is most easily accessed. Another major event of electrical construction is the Finish or Final Phase.  The Final Phase is when switches, outlets, fixtures, etc. are installed and is in the “Dry Phase” of construction. Common jargon used among electrical tradesmen is “Rough In” and “Final”.
Rough-in refers to the rough installation of the electrical wiring, boxes, fixture mounts, breaker panel, and sub panels. An inspection is generally required of the electrical work, prior to covering the work with drywall.
A building inspector will spot check, or possibly thoroughly inspect that all work meets electrical code requirements. If the work meets code requirements, the inspector will sign off and work can continue. Otherwise, corrections must be made and the work reinspected before other work can begin. Inspections are performed during both the Rough In and the Final.
