Class A Office Cleaning Prices in Seattle (2025)

Seattle Prices Highest in This Guide, and the Trophy-vs-Everything Gap Is Extreme

Class A office cleaning in Seattle runs $0.22 to $0.38 per square foot per month, the highest band of any metro in this batch, set by the highest metro janitor wage measured here. But the office market underneath that number is unusually split: downtown Seattle CBD vacancy hit a record 34.7% by the fourth quarter of 2025, and Class A vacancy sat near 32.2% in early 2025, yet trophy-class towers in the same submarket reported vacancy of just 10.2%. A contractor pricing "Seattle Class A" as one number is missing a double-digit swing in what any two buildings can actually afford.

Washington's Wage Floor Is the Highest in This Batch

BLS OEWS May 2025 reports the Seattle-Tacoma-Bellevue metro median janitor wage at $22.35/hr (SOC 37-2011), the highest figure across every city in this guide, ahead of even New York's OEWS median. Washington's state minimum wage sits at $17.28/hr, itself among the highest state floors nationally, and Seattle's own city minimum wage ordinance runs higher still for large employers. The Seattle Secure Scheduling Ordinance, effective since July 2017, layers an additional compliance requirement on large retail and food-service employers, 14-day advance schedule posting, predictability pay for last-minute changes, and a right to decline unscheduled hours, though its scope is retail and food service, not janitorial contractors directly. Commercial cleaning bids should treat it as market context rather than a direct legal requirement: it signals the kind of scheduling-fairness standard Seattle landlords increasingly expect from any vendor managing hourly staff, union or not.

Worked Bid: 65,000 Sq Ft Denny Triangle Building, Trophy-Adjacent

A 65,000 sq ft floor plate needs about 18.6 crew-hours nightly at 3,500 sq ft/hr. At the metro OEWS median of $22.35/hr, raw nightly wage runs roughly $416. Washington's burden stack is heavy: paid sick leave (mandatory statewide since 2018), paid family and medical leave payroll contributions, workers' comp rates set by the state fund rather than private carriers, and Seattle-specific payroll expense considerations for larger employers. Loaded cost typically runs 38-44% above base wage, all-in near $30.85-32.20/hr, among the highest all-in labor figures in this guide, and well above every Sunbelt metro covered.

The vacancy split matters directly to this bid: if the Denny Triangle building in question is a genuine trophy asset, it sits closer to the 10.2% vacancy pocket and the owner has budget to maintain full service; if it is an older Class A tower in the broader 32%+ vacancy pool, expect the RFP to push hard on frequency reductions before it pushes on rate.

The Four Service Bands

• Nightly only, 5 nights/week: $0.16–$0.23/sq ft/month
• Nightly + day porter: $0.22–$0.29/sq ft/month
• Nightly + day porter + quarterly floor care: $0.27–$0.34/sq ft/month
• Full-service, trophy tier with window rotation: $0.32–$0.42/sq ft/month

Compliance Beyond Secure Scheduling

Washington's statewide paid sick leave law, in effect since 2018, requires accrual of at least one hour per 40 hours worked for every employee, a floor that applies regardless of building class or union status. Combined with the state's paid family and medical leave payroll tax and workers' comp structure, Seattle contractors carry one of the densest compliance stacks in this guide even without a dominant union presence comparable to Chicago or New York. Contractors setting up in Seattle should check the cleaning business license requirements page; for Washington sales tax treatment of janitorial services, see the WA sales tax guide.

One practical wrinkle for multi-year Seattle contracts: Washington's minimum wage adjusts every January under a CPI-indexed formula, and the state's paid family and medical leave premium rate is reset annually by the Employment Security Department. A three-year Class A cleaning contract signed in 2025 without an automatic wage-escalation clause will likely be underpriced by year three, since both the wage floor and the payroll tax base move independently of anything the landlord or contractor negotiate directly.

This market pairs the highest wage floor in the country with one of the softest office markets. CBRE's Puget Sound Office Figures for Q2 2026 show total vacancy at 28.2 percent with average direct asking rents of $46.78 per sq ft full-service gross. Against that, the city's Minimum Wage Ordinance set the rate at $21.30 per hour effective January 1, 2026, up from $20.76. Class A owners cannot discount their way out of a mandated labor cost, which is why per-foot cleaning rates here hold while rents do not.
