Seattle plumbing PMs are earning $138K–$172K base in 2026, with healthcare and high-rise specialists pushing $195K total. Here's what separates the top 20% of the market.
Mid-career (8–14 years) commercial plumbing project managers in the Seattle metro (King, Snohomish, Pierce counties) are landing $138,000–$172,000 base in 2026, with 10–17% bonus and a truck or vehicle allowance of $700–$950/month. Total cash comp: $158,000–$202,000.
Senior plumbing PMs (15+ years, $30M+ project value) push to $180,000–$218,000 base with 15–22% bonus. Top of the market — biotech interior fit-outs, hospital new-builds, and Class A high-rise — lands $225,000–$248,000 total.
APM and PM I roles (2–5 years) in Seattle: $88,000–$112,000 base with 5–8% bonus. Seattle's plumbing labor market is tight enough that early-career PMs with strong Revit/BIM chops close 6–10% above metro median.
Seattle plumbing PM base sits 6–10% above Portland and 8–14% below San Francisco at equivalent experience. The gap to SF is closing because Seattle's biotech capex cycle is pulling plumbing PM demand and per-project premiums.
Large regional mechanical contractors with dedicated plumbing divisions and specialty biotech/healthcare plumbing contractors pay the top of the Seattle range. Mid-size firms ($40M–$100M) pay 5–9% below the top but often carry richer 401(k) match and PTO structures. Live Seattle plumbing PM jobs are with clients hiring at or above metro median.
Yes. Seattle's healthcare capex cycle plus continued Class A high-rise activity is running ahead of the plumbing PM talent pool. Roles at $150K+ base sit open 60–100 days on average.
