THE ROUGH-INS: WHY ARE THEY IMPORTANT

What Does Rough-In Mean?
Rough-in is a general term that can apply to any trade, but is usually associated with plumbing, electrical, and HVAC work. Rough-in is a construction stage that occurs after the basic framing is complete and begins when initial services, such as wiring or pipe, are installed; however, sinks, outlets, switches, and fixtures have not been installed. Generally, a rough-in follows the roofing, windows, and doors installation, so any plumbing, electrical, and HVAC installations are protected from exterior elements.

During the rough-in period, walls have not been closed with drywall. The lack of wall and floor coverings allow for the building inspector to easily view the electrical, plumbing, and HVAC work. At this point, if any of the work does not pass inspection, then the “trades” can easily modify their work. Inspectors examine plumbing and electrical work as well as HVAC ducting, but they can also perform water- and gas-line air pressure tests.
