What share of plumbing rough inspections pass first time in Wake County?

75% pass on the first visit. Across 60,588 plumbing rough inspections between 1996 and 2026, 25.4% failed or required a re-inspection.

Does the pass rate depend on which inspector attends?

It varies considerably. Across the 49 inspectors with at least 200 plumbing rough inspections on record, first-time failure ranges from 12.3% to 50.7%, with a median of 25.7%. Some of that reflects which areas and which builders an inspector covers rather than how they inspect.

Where does this data come from?

Public inspection records from Wake County. Only the first inspection of each permit and type is counted, so a job that fails and later passes counts once as a first-time failure. Cancelled and rescheduled visits are excluded because they are not outcomes.

What is being counted. Only the first inspection of each permit and type. A job that fails, gets corrected and then passes counts once, as a first-time failure. Cancelled and rescheduled visits are left out because they are not outcomes.

Why inspectors are not named here. Inspection records are public, but this page is about the work, not about individuals. Inspectors are not assigned at random: they cover areas, and areas differ in what gets built and by whom. A share of the spread above is that, not how anyone inspects.

For contractors
