Janitorial Wages in Washington (2026)

Washington State's commercial janitors earn the highest statewide median in this batch at $21.02/hr (BLS OEWS May 2024, SOC 37-2011 — O*NET LocalWages WA), driven by the state's robust CPI-indexed minimum wage, Seattle's $21.30/hr city floor, and SEIU 6's master agreement covering thousands of commercial cleaners in King County. The statewide minimum wage rose to $17.13/hr on January 1, 2026 under RCW 49.46.020, while Seattle's local ordinance — applicable to all employers regardless of size — reaches $21.30/hr for 2026. Washington employs approximately 65,000–75,000 janitors, with roughly 60% in the Seattle–Tacoma–Bellevue metro region.

Statewide Wage Overview (BLS OEWS May 2024, SOC 37-2011)

The statewide mean equals the median at $21.02/hr, reflecting a broad labor market uniformly elevated by the state's strong minimum wage infrastructure and Seattle's tight labor market. Annual mean wage is approximately $43,720. Washington's statewide janitorial median of $21.02/hr exceeds the national median by $3.75/hr — the largest premium of any state in this batch. This reflects both the high minimum wage floors and the SEIU 6 union presence in the dominant Seattle metro market.

Wage Percentile Distribution (BLS OEWS May 2024)

The 10th percentile at $17.11/hr is effectively the statewide minimum wage floor — essentially every Washington cleaning worker earns at least $17/hr regardless of geography. The $3.11/hr jump from 10th to the state minimum ($17.13/hr) reflects the CPI indexing tightening the lower distribution. The extraordinary $11.89/hr spread from 10th to 90th is the widest in this batch, reflecting the premium for SEIU 6 union members in Seattle Class A office towers ($26–$30+/hr) versus eastern Washington non-union workers near the state minimum.

Submarket Variation: High and Low Metro Areas

Seattle–Tacoma–Bellevue MSA leads at a median $21.55/hr (10th: $17.55, 25th: $18.38, 75th: $25.04, 90th: $29.92) — reflecting Seattle's $21.30/hr city minimum wage, the SEIU 6 union premium in Class A buildings, and the tech-sector wage competition from Amazon, Microsoft, Boeing, and other major Seattle employers. Bremerton–Silverdale–Port Orchard (Kitsap County/Puget Sound) follows closely at $21.52/hr median, reflecting the naval base complex and Puget Sound proximity. Mount Vernon–Anacortes shows $21.17/hr median. At the lower end, the Lewiston ID-WA MSA (Idaho border) drops to $17.41/hr — effectively at the state minimum floor — and Spokane–Spokane Valley posts $18.11/hr, significantly below the western Washington metro cluster but still $0.98/hr above the statewide floor. Eastern Washington non-metro areas run $20.27/hr median — higher than expected, reflecting the tight regional labor markets in agricultural-processing hubs.

State Minimum Wage 2026 and Scheduled Increases

• Statewide rate: $17.13/hr effective January 1, 2026 (RCW 49.46.020; Miller Nash LLP 2026 update). The 2026 rate increased from $16.66/hr (2025) — a 2.8% CPI-driven increase.
• CPI indexing: Washington's minimum wage adjusts each January 1 based on the prior year's CPI-W for the Seattle-Tacoma-Bellevue area. No legislative action required for annual increases.
• Tipped employees: Washington does not permit a tip credit — all workers must receive the full minimum wage of $17.13/hr, regardless of tips received.
• No scheduled step changes: Washington's rate adjusts purely by CPI, with no legislated jumps or phase-in schedules. Budget 2–4% annual increases for multi-year contracts.

Workers' Compensation — Washington L&I (State Fund)

Washington is a monopolistic state fund jurisdiction — all workers' compensation insurance must be purchased through the Washington State Department of Labor & Industries (L&I). Private WC carriers are not permitted in Washington. Rates are set by L&I and vary by risk classification (Washington uses its own classification system, not NCCI codes). The equivalent commercial janitorial rate (Washington risk class for building cleaning) runs approximately $1.80–$2.50/$100 payroll based on L&I 2024 rate schedules — the state fund's rates are competitive due to favorable claims experience in the commercial cleaning sector. The rate includes both employer and employee portions combined. Loaded labor cost at $21.02/hr base: add FICA/FUTA $1.68, WC (L&I) ~$0.40–$0.53/hr, general liability, benefits, and overhead — total loaded approximately $33–$40/hr for non-union accounts. SEIU 6-covered Seattle union accounts run $38–$50/hr total loaded with full health and welfare contributions.

Union Presence — SEIU 6 Property Services NW

SEIU 6 (Property Services Northwest) represents commercial janitors, security officers, airport workers, and other property services workers in Washington and Oregon. The 2024–2028 Janitorial CBA (ratified in 2024) covers an estimated 6,000–8,000 commercial janitors in the greater Seattle metropolitan area, including King, Pierce, and Snohomish Counties. SEIU 6's geographic jurisdiction covers the Puget Sound region; the Oregon portion of its operations focuses on Portland. The 2024–2028 contract covers Class A office buildings, tech corporate campuses, and healthcare facilities in the Seattle metro. Members contact the union at 206-448-7348 for contract questions. Union density in Seattle downtown Class A office cleaning is estimated at 50–70%. Eastside markets (Bellevue, Redmond, Kirkland) are a mix of union and non-union, with major tech campus accounts often organized.

Local Minimum Wage Premiums

• Seattle: $21.30/hr effective January 1, 2026 — applies to ALL employers regardless of size (Seattle unified all employers in 2025; Seattle Office of Labor Standards)
• Tukwila: $21.65/hr for employers with 15+ employees (highest rate in Washington state — Miller Nash)
• Renton (500+ employees): $21.57/hr effective January 1, 2026; smaller employers: $20.57/hr (Jan–June 2026), $21.57/hr (July–December 2026)
• Unincorporated King County: $20.82/hr (500+ employees); $19.82/hr (15–500 employees); $18.32/hr (15 or fewer employees with under $2M gross revenue)
• SeaTac: $20.74/hr for hospitality and transportation industry employees (applies to Sea-Tac Airport contract cleaning)
• Bellingham: Has a local minimum wage ordinance — verify current rate for accounts in Whatcom County

What Contractors Should Bid Against

Loaded labor range: Eastern Washington non-union accounts (Spokane, Yakima, Tri-Cities) price at $28–$34/hr total loaded. Seattle non-union accounts in non-union buildings run $33–$40/hr. SEIU 6-covered Seattle Class A office accounts require budgeting $38–$50/hr total loaded — the highest in this batch alongside New York.

Key bid pitfalls:

• Multiple local floors in King County: A Seattle account requires $21.30/hr; a Tukwila account requires $21.65/hr; a Renton account requires $21.57/hr (large employer) or tiered rates. The differences between these floors for a multi-site King County contract can add meaningful labor cost if any sites are misclassified.
• No tip credit: Washington prohibits tip credits. All workers, including those at restaurant-adjacent or hospitality-adjacent cleaning accounts, must receive the full applicable minimum wage.
• L&I state fund requirement: Unlike most states, Washington requires all WC insurance be purchased from L&I. Out-of-state contractors entering the Washington market must register with L&I and open a state fund account — there is no option to use a private carrier.
• January vs. July increases: Seattle and other city floors typically adjust January 1; Washington state minimum adjusts January 1; but some local jurisdictions (Renton) have mid-year adjustments. Track all applicable floors' effective dates for multi-site contracts.
