Rough-in

Definition and meaning of Rough-in in real estate.

A rough-in is the stage of construction where plumbing, electrical, and mechanical systems are installed within the wall and floor framing before the drywall or plaster is applied.

In more detail

During this phase, pipes, wiring, ductwork, and electrical boxes are run through studs and joists, but fixtures like sinks, outlets, and light switches are not yet connected. This stage is crucial because it allows local building inspectors to examine the work and verify code compliance while the walls are still open.

Once the rough-in passes inspection, the builder can install insulation and hang drywall. Changing these systems after the drywall is up is significantly more expensive and labor-intensive.
