Average Janitorial Business Insurance Cost (2026 Report)

Note: These are modeled monthly averages for a small janitorial operation with one to four employees at standard policy limits, calculated across all 50 states and Washington, D.C., before any discounts, and they are estimates rather than quotes. Workers' comp is priced per employee, and commercial auto reflects minimum coverage for a work vehicle. The business owner's policy figure is derived from general liability and commercial property pricing, and the janitorial bond, hired and non-owned auto and commercial umbrella rates come from external research rather than the MoneyGeek dataset.

A business owner's policy is the base most janitorial operations build on, bundling general liability and commercial property into one policy that covers third-party claims and your own equipment. It averages $133 per month, or $1,596 per year, which typically costs less than buying the two coverages separately.

• What it covers: third-party bodily injury, damage to a client's property, your own equipment and supplies, lost income after a covered loss
• Common covered risks: a client slips on a floor your crew just mopped, a cleaner knocks a monitor off a desk, a fire at your storage unit destroys buffers and chemical stock
• Requirement considerations: often the base coverage a commercial lease or client contract names, usually written at $1 million per occurrence and $2 million aggregate on the liability side
• Who needs it: nearly every janitorial operation with equipment or a fixed location

Because a BOP is built from general liability and commercial property, its cost tracks the same state gaps those two coverages do. A California operation pays around $212 per month while one in West Virginia runs about $93, a spread of roughly 2.3 times that comes almost entirely from the general liability side, since commercial property barely moves. Litigation frequency and claim severity in your state set the number.

General liability is the coverage commercial clients most often require before your crew sets foot on their property, paying for third-party injuries and damage your work causes. It averages $118 per month, or $1,419 per year, at standard $1 million per-occurrence and $2 million aggregate limits.

• What it covers: third-party bodily injury, third-party property damage, legal defense costs, advertising injury
• Common covered risks: a guest trips over a wet-floor sign, a cleaner scratches a client's hardwood, a mop bucket topples onto office electronics
• Requirement considerations: the coverage commercial property managers name in contracts, usually $1 million per occurrence and $2 million aggregate
• Who needs it: every janitorial business that sets foot on a client's property

West Virginia averages around $76 per month while California runs about $200, a gap driven by claim severity and litigation frequency rather than the work itself. If your crews clean in a high-density metro, your rate will likely sit above your state's average, not at it.

Commercial property covers the equipment, machinery and chemical supplies your operation owns, wherever you store them. It averages $30 per month, or $366 per year, and scales with the replacement value of what you keep on hand rather than your location.

• What it covers: cleaning equipment, powered machinery, chemical inventory, contents at a fixed location
• Common covered risks: a fire in your storage unit, a burst pipe ruins stored supplies, buffers and extractors stolen from your office
• Requirement considerations: limits set to the replacement value of what you own, higher if you store high-value machinery centrally
• Who needs it: operators who own equipment or keep supplies at a storage unit, office or warehouse

North Dakota averages around $27 per month and New York about $37, a $10 gap. What moves your commercial property premium is what you own and where you store it, not your state, so a van loaded with extractors and chemical inventory at a central facility costs more than a solo operator's single vacuum.

Workers' comp pays medical bills and lost wages when a cleaner is hurt on the job, and janitorial work generates those claims at a higher rate than most service trades. It averages $101 per employee per month, or $1,210 per employee per year, and most states require it once you have employees.

• What it covers: employee medical bills, lost wages, disability benefits, employer's liability
• Common covered risks: a cleaner strains a back lifting equipment, a chemical burn from a mishandled solvent, a slip on a wet floor mid-shift
• Requirement considerations: mandated by state law once you have employees, class code driven by the cleaning work performed
• Who needs it: any janitorial business with employees, required in most states

New York averages around $244 per employee per month while Indiana runs about $56, roughly 4.4 times less. The gap reflects state benefit structures and claim cost rules, not how your crews work, so the same job priced in two states can land far apart. North Dakota, Ohio, Washington and Wyoming run workers' comp through a state fund, so there's no private-market rate to quote; add your state-fund rate instead.

Commercial auto covers your company vans and the crews who drive them to every job, from accident liability to damage to the vehicle itself. It averages $185 per month, or $2,220 per year, which makes it the most expensive single coverage for operations that run their own vehicles.

• What it covers: accident liability in company vehicles, physical damage to your vans, medical payments, equipment in transit within policy terms
• Common covered risks: a crew van rear-ends a car on the way to a job, a company truck is broken into at a site, a driver clips a client's gate
• Requirement considerations: required in every state for company-owned vehicles, minimum limits vary by state
• Who needs it: operations that own vans or trucks for reaching client sites

Michigan sits at around $353 per month while Pennsylvania averages about $92. Michigan's no-fault system historically required unusually high personal injury protection benefits, which pushes commercial auto well above what most states see, so in no-fault or high-litigation states this tends to be your most expensive single coverage.

Cyber insurance matters once your operation holds client building-access codes, security credentials or payroll data, covering breach response and the liability that follows. It averages $82 per month, or $985 per year, and scales with how much sensitive access data you manage.

• What it covers: breach notification costs, data recovery, liability for exposed client data, covered regulatory fines
• Common covered risks: client building-access codes leak in a breach, payroll data is stolen, ransomware locks your scheduling system
• Requirement considerations: driven by the volume and sensitivity of client access data you hold, some commercial accounts require it
• Who needs it: operations that store building-access credentials or manage digital access for commercial accounts

Washington, D.C. averages around $101 per month while Montana, Wyoming and Alaska each run about $70, a 44% difference tied to how aggressively each state enforces data breach notification rules. If you store client access codes or payroll data, a breach in a high-regulation state triggers broader notification duties and higher litigation exposure.

Professional liability covers claims that your cleaning service fell short of a contracted standard, a narrow exposure for janitorial work since most claims trace to physical incidents instead. It averages $13 per month, or $161 per year, so if a commercial contract requires it, adding it won't move your budget.

• What it covers: claims of negligence in a professional service, failure to meet a contracted standard, related legal defense
• Common covered risks: a client says your cleaning missed a contracted specification, a service failure they claim caused them a loss
• Requirement considerations: written to $1 million per claim and $1 million aggregate, sometimes named in commercial cleaning contracts
• Who needs it: operators whose contracts specify it, otherwise a minor exposure for janitorial work

Professional liability barely moves across states. Maine, North Carolina and North Dakota average around $12 per month while Washington, D.C. reaches about $16, so wherever you operate, this stays a small line for janitorial work.

These specialty coverages sit beyond the standard mix. Most janitorial operations add them only when a contract or their staffing calls for it.
