What is the salary and career path for a plumbing inspector?
BLS does not publish a separate wage for plumbing inspectors; they sit inside the broader code Construction and Building Inspectors, SOC 47-4011, which also covers building, electrical, mechanical and public-works inspectors, so the figure is approximate for the plumbing speciality alone. That code shows an OEWS May 2025 median of $74,690 a year ($35.91 an hour), from $47,140 at the 10th percentile to $114,200 at the 90th. The usual entry route is a journeyman or master plumber's licence plus several years in the trade, followed by ICC certification — commonly the P1 Residential Plumbing Inspector or P2 Commercial Plumbing Inspector exam — and appointment by a city, county or third-party agency. Employment in this code is projected to shrink 0.8% over 2024–2034, an outright decline, though roughly 14,800 openings a year still arise as an older inspector workforce retires.
- Plumbing Inspectors earn a national median $74,690/yr ($35.91/hr) (BLS OEWS May 2025, SOC 47-4011); the top 10% clear $114,200.
- The route runs through the trade: a journeyman or master plumber licence plus ICC P1/P2 certification, not a degree.
- BLS projects a 0.8% decline for construction and building inspectors 2024–34, with about 14,800 openings a year coming almost entirely from retirements.
- The ladder runs journeyman plumber to plumbing inspector to combination inspector to plans examiner or chief building official.
