During which part of the construction process does a rough-in inspection take place?

A rough-in inspection is a key stage in the construction process, taking place once all framing and plumbing are roughed in. This means the inspection occurs after the structural framework (like walls and ceilings) has been built and the plumbing piping and ductwork have been installed but before any fixtures, such as sinks, toilets, or bathtubs, are added.

This inspection is crucial as it ensures that the plumbing system is installed correctly and aligns with the relevant codes before the walls are closed up with drywall or other finishing materials. Inspectors look at the piping layout, verify that all venting is properly set up, and check for adherence to local codes and standards at this stage.

The other options do not align with the purpose and timing of a rough-in inspection. For instance, waiting until the entire system is installed or after final inspections would hinder the ability to make any necessary corrections once finishing materials are applied. Similarly, the inspection cannot happen as soon as fixtures are placed, since these fixtures are installed after the rough-in inspection has been completed.
