Insurance Requirements for
Commercial Cleaning Vendors
Accepting a certificate of insurance is not the same as verifying coverage. Here is what facility managers need to require, how to verify it, and what happens when a cleaning vendor does not carry adequate insurance.
In most states, if a cleaning contractor does not carry workers compensation and a worker is injured at your facility, you may be liable as a statutory employer. A certificate on file does not protect you if the policy was canceled before the incident. (NCCI, state workers comp statutes)
The Short Answer
A commercial cleaning vendor should carry four types of coverage at minimum: general liability ($1M per occurrence, $2M aggregate), workers compensation at statutory limits, commercial auto if vehicles are used, and an umbrella policy of at least $5M for larger or higher-risk facilities. You should also require additional insured status on a standard endorsement form and verify coverage directly with the insurer, not just accept the certificate the vendor provides.
Risk Management
A slip-and-fall in a freshly mopped lobby sent a visitor to the hospital. The cleaning vendor carried $500K in general liability. The claim settled for $1.1M. The facility operator's policy covered the gap. The facility manager did not know the vendor's limits were below their own contract standard until the claim was filed.
Per occurrence and aggregate general liability minimums for commercial cleaning vendors. Umbrella of $5M or more for larger facilities. Verify directly, not from the certificate alone.

The Four Required Coverage Types
Every commercial cleaning vendor operating at your facility should carry these four types of insurance. Each one addresses a different category of exposure. Missing any one of them creates a gap that can land on your organization.
Covers third-party bodily injury and property damage arising from cleaning operations. This is the primary policy covering slip-and-fall claims, damage to client property, and incidents involving building occupants. For high-traffic facilities or environments with expensive equipment or finishes, require higher limits.
Covers cleaning workers injured while performing work at your facility. Janitorial workers fall under NCCI Class Code 9014, one of the higher-risk worker classifications, with rates averaging $2.43 per $100 of payroll. Without this coverage on the vendor's policy, your organization may carry statutory employer liability in most states.
Required when the vendor transports equipment, supplies, or personnel using company vehicles. Covers bodily injury and property damage from vehicle incidents while traveling to or from your site. Personal auto coverage does not extend to commercial use.
Provides coverage above primary policy limits for catastrophic claims. A $1M general liability limit can be exhausted quickly by a serious bodily injury claim. An umbrella policy of $5M to $10M provides the buffer needed for large facilities, healthcare environments, manufacturing plants, and high-footfall venues.
Additional Insured Status: Why It Matters
A cleaning vendor's general liability policy covers claims arising from their operations. But without an additional insured endorsement naming your organization, you have to rely on the vendor actively cooperating in your defense if a claim arises. An additional insured endorsement makes your organization a named party on the policy, giving you direct rights to coverage for claims arising from the vendor's work at your facility.
The endorsement should be on ISO form CG 20 10 (ongoing operations) or CG 20 37 (completed operations), or their equivalent. A generic "blanket additional insured" endorsement may be acceptable, but verify the form language covers your exposure scenario. Require the endorsement to be listed on the certificate of insurance, and verify directly with the agent that the endorsement is in place.
Any commercial cleaning vendor who objects to providing additional insured status is outside normal commercial standards. It is a routine requirement and a vendor who pushes back on it warrants scrutiny.
Workers Compensation: The Statutory Employer Risk
The statutory employer doctrine is the most underestimated insurance risk in commercial cleaning vendor relationships. Most facility managers assume that because the cleaning workers are not their employees, any injury claim is entirely the vendor's problem. In many states, that assumption is wrong.
States including Florida, South Carolina, Georgia, Tennessee, and others have statutory employer provisions that can hold the property owner or general contractor liable for workplace injuries when the direct employer does not carry workers compensation. The specific trigger conditions vary by state, but the pattern is consistent: if the cleaning vendor cannot pay, the property owner or occupant may be next in line.
The protection is straightforward: require workers compensation coverage in the contract, verify it is active before the first crew arrives, and re-verify at each contract renewal. Do not accept a certificate that is close to expiration without getting a current one.

How Compliance Platforms Handle Insurance Verification
Facilities enrolled on Avetta or ISNetworld have a structural advantage in insurance verification. Both platforms require enrolled contractors to submit current certificates, verify coverage against facility-operator-defined minimums, and alert both parties when policies approach expiration. A contractor whose coverage lapses can be automatically suspended from the platform, blocking access to enrolled facilities.
For facilities not enrolled on a compliance platform, the verification burden sits entirely with the facility manager. Build a calendar reminder at 60 days before each annual certificate expiration and require the vendor to provide an updated certificate proactively, not reactively.

Frequently Asked Questions
The industry baseline is $1 million per occurrence and $2 million aggregate. For facilities over 100,000 square feet or those with significant foot traffic, slip-and-fall exposure, or specialty environments like healthcare, $2 million per occurrence and $4 million aggregate is more appropriate. For large corporate campuses or high-value properties, require an umbrella policy of at least $5 million. These minimums should be written into the contract, not just verified once at signing.
Do not rely solely on the certificate of insurance the vendor provides. Certificates can be produced with incorrect dates or for policies that have since lapsed. Contact the issuing agency directly, using the contact information from the certificate, and request verbal or written confirmation that the policy is active and in good standing. Ask specifically about any past cancellations or lapses in the prior 24 months. For high-value facilities, an annual verification review at contract renewal is a reasonable standard practice.
An additional insured endorsement adds your organization to the cleaning vendor's liability policy so that claims arising from their work at your facility are covered under their policy rather than yours. This is standard practice in commercial facility services and you should require it in the contract language. The endorsement should be on a standard form (ISO CG 20 10 or equivalent) and should be listed on the certificate of insurance. A vendor who resists providing additional insured status is a significant red flag.
Most states have statutory employer laws that can hold the property owner or occupant liable for workplace injuries when the direct employer (the cleaning contractor) does not carry workers compensation. The specific statutes vary by state, but the risk is real and documented. Even in states with narrower statutory employer provisions, you may face general liability claims from injured workers. Requiring workers compensation coverage in the contract, and verifying it annually, is the only structural protection.
Yes, if the vendor transports equipment, supplies, or personnel to your facility using company vehicles. Commercial auto coverage at minimum limits of $1 million combined single limit covers bodily injury and property damage arising from vehicle use. If a vendor's vehicle is involved in an accident while traveling to or from your site, and they carry only personal auto coverage (or none), liability exposure can flow back to your organization depending on the circumstances. Commercial auto is a standard requirement for any vendor operating on your premises regularly.
An umbrella policy provides coverage above the limits of the underlying policies (general liability, commercial auto, employers liability). For standard commercial cleaning accounts under 50,000 square feet with low-risk environments, the primary policy limits may be adequate. For facilities over 100,000 square feet, healthcare environments, manufacturing plants, entertainment venues, or any facility with high foot traffic, require a minimum $5 million umbrella. Some large corporate accounts and property managers require $10 million umbrella as a condition of vendor approval.
Professional liability (E&O) is less commonly required for janitorial services than for professional services firms, but it becomes relevant in specific scenarios. If the vendor provides cleaning program consulting, manages a facility's entire janitorial supply procurement, or provides quality inspection services as a standalone offering, E&O coverage of $1 million is a reasonable addition. For standard cleaning service agreements, general liability and workers compensation are the primary requirements.
Avetta and ISNetworld both include insurance certificate collection and verification as part of their contractor management platforms. Vendors enrolled on these platforms must upload current certificates, which are reviewed against the facility operator's minimum requirements. When a policy approaches expiration, the platform generates alerts and can suspend the contractor's status if the certificate is not renewed. For facilities enrolled on these platforms, the insurance verification burden shifts substantially to the platform, but you should still confirm the minimum requirements loaded into the platform match your actual exposure.
