Certificates of Insurance for Cleaning Vendors: What NYC Building Managers Ask For
What a certificate of insurance is, what NYC building managers commonly ask cleaning vendors for, and how additional insured status, workers' compensation, liability and bonding fit together. Educational only, not legal advice.
Quick answer
What insurance documents do NYC buildings usually ask cleaning vendors for?
NYC building and property managers commonly ask a cleaning vendor for a certificate of insurance (COI) showing general liability coverage and workers’ compensation, often with the building owner and management company named as additional insureds. Some also ask about umbrella coverage or bonding. Requirements differ by building, so tenants should get the exact list from building management before hiring a cleaning vendor. This guide is general information, not legal or insurance advice.
What a certificate of insurance is
A certificate of insurance, usually called a COI, is a one- or two-page summary issued by a vendor’s insurance broker or carrier. It lists the policies the vendor holds, the insurers, the policy numbers, the coverage limits and the policy dates. Many certificates are issued on a standard industry form, which makes them easier for building staff to review.
A COI is evidence that coverage existed when it was issued. It does not by itself change the policy or create coverage. That is why building managers often ask for a fresh certificate for each vendor and each project, and why they check that the policy dates cover the period when the work will happen.
For a cleaning vendor, the COI is usually one of the last items standing between a signed agreement and the first night of work. Building staff often will not issue access cards, add crew names to the security list or release a freight elevator slot until the certificate has been reviewed and approved. Treating it as a planning item, rather than paperwork to sort out later, keeps the start date on track.
The coverage most buildings look for
Each building sets its own vendor requirements. These are the items that come up most often in Manhattan:
General liability
Covers claims for property damage or injury to third parties arising from the vendor’s work. Buildings usually set a minimum limit per occurrence and in aggregate.
Workers' compensation
Covers the vendor’s own employees if they are injured on the job. Buildings typically want proof the vendor carries it for its workforce.
Additional insured status
Extends the vendor’s liability coverage to named parties, often the building owner and managing agent, for claims arising from the vendor’s work.
Umbrella or excess liability
Adds limits above the primary liability policy. Some buildings ask for it, particularly for larger projects or higher-risk work.
Commercial auto
Relevant when vendor vehicles are used for the work, for example to haul equipment or materials to a loading dock.
Additional insureds and certificate holders
Two terms on a COI cause the most back-and-forth. The certificate holder is the party the certificate is issued to, usually the building or management company. Being the certificate holder simply means you received a copy. Additional insured status is different: it is added to the policy itself, typically by endorsement, and gives the named parties a defined level of protection under the vendor’s coverage.
Building managers usually provide exact wording: the legal names of the owner entity, the managing agent and sometimes the tenant, written precisely as they want them to appear. Small differences in an entity name can lead to a certificate being rejected, so pass the wording to the vendor exactly as you received it.
Some buildings also ask for specific endorsements to be attached, such as wording that the vendor’s coverage applies before the building’s own, or a waiver of subrogation. These are policy terms rather than items on the certificate itself, and their meaning can vary. If you are unsure what a requested endorsement does, ask the building’s management company or your own insurance advisor to explain it.
Bonding is not the same as insurance
Bonding and insurance are often mentioned together, but they do different jobs. Liability insurance responds to accidental damage or injury connected to the vendor’s work. A bond is a separate arrangement, and the type matters: some bonds are aimed at guaranteeing performance of a contract, while others, often called janitorial or business service bonds, are aimed at protecting clients against theft by the vendor’s employees.
Because cleaning crews often work after hours with keys, access cards and alarm codes, some tenants ask whether a vendor is bonded in addition to insured. If a bond is part of your requirements, ask what type it is and what it covers. Your own insurance broker or legal advisor can tell you whether it fits your risk.
Requirements vary by building and by project
There is no single citywide checklist for vendor insurance in commercial buildings. A Class A office tower, a retail property and a smaller loft building may each ask for different limits, different additional insureds and different supporting documents. Requirements for a one-time post-construction clean can also differ from those for an ongoing nightly cleaning contract in the same building.
Regulations and industry practice change too, and some requirements come from the lease rather than the building’s vendor policy. Treat any general description, including this one, as background. Confirm the exact requirements with your building or management company, and involve your own broker or legal advisor if a term affects your company’s risk.
How to collect a COI without delaying the start date
- Get the building's requirements in writing. Ask building management for its vendor insurance requirements, minimum limits and exact additional insured wording before you request proposals.
- Share them with every bidder. Include the requirements in your scope so each vendor confirms it can meet them and prices accordingly.
- Request the certificate early. Ask the selected vendor’s broker to issue the COI as soon as the contract is signed. Building review can take time.
- Check dates, limits and names. Confirm the policy dates cover the work, limits meet the minimums and names match the requested wording.
- Track renewals. Diary policy expiration dates and request an updated certificate before coverage renews, so access is not interrupted.
Citywide's insurance and documentation
Citywide Maintenance Services is bonded and carries full liability and workers’ compensation insurance. Every Citywide cleaner is a Citywide employee. We do not subcontract any of our work, we run background checks on every employee we hire, and our staff are trained in company procedures and arrive in uniform.
If your building or management company has specific COI requirements, share them during the proposal stage and Citywide can discuss the documentation needed before the first visit. For the broader picture of what to agree in writing, see our scope of work checklist.
- Bonded
- Liability and workers’ compensation insurance
- Employees, not subcontractors
- Background-checked staff
Frequently asked questions
Is a certificate of insurance the same as an insurance policy?
No. A COI summarizes coverage at the time it was issued; the policy itself sets the actual terms. If you need to know exactly how coverage applies, ask for the relevant endorsements or consult your own broker.
Who decides what limits and additional insureds are required?
Usually the building owner or managing agent, sometimes through the lease. Requirements vary from building to building, so confirm the current list with your building or management company rather than relying on a general rule.
Does a tenant need to be named on the cleaning vendor's COI?
It depends on the lease and the building’s requirements. Many tenants ask to be named alongside the owner and managing agent. Check with your building and, if needed, your own insurance advisor.
Why would a building reject a certificate?
Common reasons include expired or soon-to-expire policy dates, limits below the building’s minimums, missing additional insured wording, or entity names that do not match exactly. Sending the building’s written requirements to the vendor up front avoids most of these.
Can Citywide provide insurance documentation for my building?
Yes. Citywide is bonded and carries liability and workers’ compensation insurance. Share your building’s COI requirements during the proposal stage and Citywide can discuss the documentation needed before work begins.
