How do you start a commercial office cleaning business in 2027?
Honest 5/10 take.
Startup costs: $3k-$15k. Vacuums (commercial backpack $400-$800), buffer/burnisher $1k-$3k optional, microfiber, mop systems, EPA-registered disinfectant, caddy. Branded shirts, magnetic truck signs $200-$500. LLC + general liability ($800-$1.5k/yr) + janitorial bond ($100-$300/yr). Most jobs are nightly so a used cargo van $8k-$20k helps but you can start in a sedan.
Permits: Business license, EIN, sales tax permit if your state taxes janitorial (some do). Bond is what property managers actually ask for.
Acquisition: Cold-walk strip malls and medical/dental offices at 4-6pm � decision-maker is usually onsite. Property managers control 10-50 buildings each, find them on LoopNet/CoStar lookups. Thumbtack and Angi are weak for B2B janitorial. Nextdoor is residential. Better: BNI groups, commercial real estate brokers, LinkedIn outreach to office managers.
Revenue model: $0.08-$0.15/sqft for nightly, monthly contracts. 5k sqft office = $400-$750/mo, 3-5x/wk. Net margin 20-35% solo, 10-20% with subs.
Year-1: $40k-$90k revenue solo, 8-15 accounts. Slow ramp � sales cycle is 30-90 days because contracts are annual. Churn comes from price-shopping property managers.
