Construction & Process

Rough-In

Also known as: Rough-In Stage, Rough Plumbing/Electrical

Definition

The construction phase where the basic framework of plumbing, electrical, and HVAC systems is installed inside the walls before drywall goes up. This is when the pre-drywall inspection should happen.

Detailed Explanation

Rough-in refers to the installation of mechanical systems (plumbing pipes, electrical wiring, HVAC ductwork) before the walls are closed up with drywall. The systems are not yet functional — faucets, outlets, and vents are not yet installed — but the infrastructure is in place.

Each system has its own rough-in inspection by the local building department: rough plumbing, rough electrical, and rough HVAC. These inspections must pass before the builder can proceed to drywall.

The rough-in stage is the ideal time for a pre-drywall inspection because all the home's hidden systems are still visible and accessible.

In Your Contract
