Rough-In

The first phase of plumbing, electrical, or HVAC work before walls are closed.

Definition

Rough-in is the stage at which pipes, wires, or ducts are installed in framing but not yet connected to fixtures or finishes — completed before drywall.

In plain English

Must pass inspection before any walls are closed. Rough-in mistakes are expensive to fix after drywall is up.

Example

An electrician completes the rough-in by running all wiring to outlet boxes and the panel, then waits for inspection before the drywaller arrives.
