In the Field · Part 4
Template: the pre-inspection checklist by stage. Underground, rough, water heater final, gas, and trim
Lesson 24 of 27~6 minFree previewCurrent as of September 2026
The inspector's checklist, run by you the day before, with the section next to each line. Five blocks: underground before backfill, rough before the walls close, the water heater final, the gas test, and trim. Fifteen minutes with this sheet is the difference between the case in lesson 4.20 and a first-time pass.
What the full lesson covers
- Run the block for the stage the day before the call, with a tape, a level, a gauge, and the phone camera.
- Photograph every test gauge with the time at start and end; photograph the straps, the T&P termination, the sediment trap, the bond clamp.
- Corrections from the last inspection: read the notice, look up each section cited, fix every rule in the section, then call.
- Add the city's local amendments to the blank lines; they are the items the state checklist does not have.
