Work requiring a rough-in inspection would include all except____.

• A. registers and grilles
• B. ducts above a drop in ceiling
• C. gas piping within a wall
• D. duct work within a wall

Answer: (A)

Rough-in inspections cover work that happens behind walls or above ceilings before finishing surfaces are put in place. This stage checks that duct runs, gas piping, and other mechanical lines are properly located, sized, supported, and free from leaks so everything can be closed up safely. Ducts inside walls and ducts laid out above a drop ceiling, as well as gas piping within walls, are installed and inspected at this stage because they are concealed and must meet code before finishing work proceeds. Registers and grilles, on the other hand, are finish components installed after rough-in, once walls and ceilings are complete. They don’t get checked during the rough-in because they’re not part of the concealed installation that the rough-in inspection verifies.
