Labor market

Seattle sets the highest big-city minimum wage in the United States at $21.30/hr for 2026 (well above Washington’s $17.13/hr state floor), and BLS reports a local median janitor wage around $22.35/hr — making Seattle one of the most expensive U.S. metros for janitorial labor.

Cost drivers

Highest big-city minimum wage in the U.S. ($21.30/hr, 2026), Wet-season entryway and floor-care frequency, Specialized tech-campus, aerospace, and lab protocols, Facility size and 24/7 operating schedules

• Large tech-campus office footprints
• Aerospace and advanced-manufacturing facilities
• Wet-climate floor care and moisture management
• Healthcare and life-sciences expansion

Seattle pairs one of the densest concentrations of large tech and aerospace employers in the country with a long, wet marine climate — so demand is anchored by big corporate-campus janitorial programs and amplified by year-round rain that keeps entryway, slip-safety, and moisture-control cleaning in near-constant demand.

Cool marine west-coast climate: mild temperatures with a long, wet season from October through May that delivers frequent rain and persistent damp conditions rather than heavy snow.

• Persistent rain & entryway moisture — Months of frequent rain track water and grit through entrances, requiring heavy matting, wet-floor slip-safety protocols, and frequent day-porter attention across the long wet season.
• Mold & mildew from damp conditions — Sustained humidity and damp promote mold and mildew in restrooms, carpets, and low-airflow areas, raising demand for moisture management and specialized remediation-adjacent cleaning.
• Tracked-in mud & organic debris — Rain plus abundant tree cover pulls in mud, leaves, and organic matter, driving carpet care and hard-floor cleaning frequency.
