BLS metro-level wage data places Stationary Engineers and Boiler Operators pay in Fresno, CA at a median of $87,140 per year ($41.89/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $78,620, Fresno pays +11% above, signaling either concentrated employer demand, a cost-of-living premium, or both. Approximately 120 stationary engineers and boiler operatorss are employed across the Fresno MSA in SOC 51-8021.

The Fresno pay distribution spans from $47,780 at the 10th percentile to $124,600 at the 90th — a 2.6× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro. The 25th percentile sits at $74,470 and the 75th at $103,690, so half of Fresno-based stationary engineers and boiler operatorss earn within that middle band.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Fresno, CA covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide CA data, and peer-metro comparisons — a median is a starting point, not a ceiling.
