How much do mechanical inspectors make in 2026?
Mechanical inspectors are counted in the BLS construction and building inspectors series: OEWS May 2025 puts the SOC 47-4011 national median at $74,690 a year ($35.91 an hour), with the bottom 10% near $47,140 and the top 10% at $114,200. Mechanical inspection sits around and above that pooled median depending on scope. The residential end is heating and cooling equipment, duct systems, combustion air and venting, and gas piping in dwellings. The commercial end is substantially harder: air handling and ventilation systems designed to code airflow requirements, smoke control and fire damper installations, refrigeration machinery rooms, hydronic and steam systems, and fuel gas piping at commercial pressures. Beyond the mechanical code sit two adjacent scopes that pay well where a jurisdiction assigns them: boiler and pressure vessel inspection, which is often a separate state function with its own commissioning, and refrigeration plant inspection. Most mechanical inspectors arrive from HVAC or pipefitting backgrounds, and combination certification with plumbing is common because the two disciplines overlap in the field. Employment is projected to change by -0.8% through 2034 with roughly 14,800 openings a year. → Full mechanical inspector career guide, career path, credentials & placement →
Note: $74,690 blends every experience level and every setting in this occupation. For pay by level alone, see Pay by Level below.
- Mechanical Inspectors earn a national median $74,690/yr ($35.91/hr) (BLS OEWS May 2025, SOC 47-4011); the P10 to P90 range is $47,140 to $114,200.
- Mechanical inspection draws on the pooled building inspectors series — a $74,690 median inside a $47,140 to $114,200 band — and sits around or above that median depending on certified scope.
- Commercial mechanical scope is where the pay is: code airflow and ventilation, smoke control and fire dampers, refrigeration machinery rooms and commercial fuel gas piping.
- Boiler and pressure vessel inspection is frequently a separate state function with its own commission, and holding it alongside mechanical certification widens both scope and pay.

How much do mechanical inspectors earn at each level?
BLS OEWS publishes one blended wage for the whole occupation and does not break pay out by credential or practice level. The levels below distribute the published percentile range across the credential tiers this role actually hires at.
Level medians are aligned to the BLS OEWS May 2025 percentile distribution for SOC 47-4011; GlobalCybers does not yet publish a verified placement sample for this role, so no verified median is shown.
Methodology & Sources
How the numbers on this page are built
Published (BLS): BLS OEWS May 2025, SOC 47-4011, United States national estimate. Public, methodologically rigorous, but sampled on a rolling 3-year basis and published ~10 months after collection — so it reflects wages that are already 1–2 years old by the time you read them.
Level and certification medians: distributed across the published BLS percentile range for this SOC code (P10 through P90) according to the credential tiers this occupation actually hires at. They are modeled reference points, not separately surveyed wages.
State and metro figures: modeled — the BLS national median multiplied by the GlobalCybers state wage index, and for metros by the published metro index for that state. They are estimates of local pay, not BLS state or metropolitan-area observations, and are labelled as modeled in the tables below.

Pay by Career Level
How much does a mechanical inspector earn at each career stage?
Mechanical inspection pay follows certified scope: residential, then commercial, then plan review or boiler commission. Each median is anchored to the BLS OEWS distribution for SOC 47-4011.
By State
Which states pay mechanical inspectors the most in 2026?
The state figures below are modeled estimates — the BLS national median multiplied by the GlobalCybers salary-calculator state wage index — not BLS state observations. Mechanical inspection scope varies by state in ways the model cannot capture: some states run boiler and pressure vessel inspection as a separate commissioned function, some fold fuel gas into plumbing, and adopted code editions differ, all of which changes what a mechanical inspector is paid to cover.

By Metro
Which cities pay mechanical inspectors the most?
Metro figures are modeled — national median times state wage index times published metro index — not BLS MSA observations. Metro authorities with high-rise and institutional construction pay best, because that work brings smoke control, refrigeration machinery rooms and complex ventilation systems that a suburban permit stream never produces.

Certification Impact
Which certifications raise a mechanical inspector’s pay the most?
Median annual pay before and after each credential, based on GlobalCybers placement data cross-referenced with BLS. License upgrades move the needle most; stackable certs add on top.

Trade Comparison
How does mechanical inspector pay compare to related roles?
BLS OEWS national median across the closest trades. Mechanical Inspectors sit mid-pack on median but carry one of the widest P10–P90 spreads, licensing and specialization drive the upside.

The medians above are gross base wage.
Estimates use 2026 federal brackets, standard deduction, and 7.65% FICA. Actual take-home varies with filing status, deductions, and local tax.
