Vendor Insurance Requirements Every Property Manager Should Enforce

Every vendor who sets foot on a property you manage—the landscaper, the roofer, the elevator tech, the guy pressure-washing the parking garage—is a potential source of liability. When someone gets hurt or something gets damaged, the injured party and their attorney look for every available pocket. If your vendor isn't properly insured, that search often ends at the property owner and the management company.

Enforcing consistent insurance requirements is one of the highest-leverage risk controls a property manager has, and it costs nothing but discipline. This article walks through the core coverages you should require from every vendor before they start work, sensible ways to think about limits, and a verification process that actually holds up.

This is general information, not legal or insurance advice. Your specific requirements should be set with your broker, your attorney, and the terms of your management agreement and owner's policies in mind.

Why Vendor Insurance Is a Property Manager's Problem

A property manager sits in the middle. You don't own the building, but you direct the work. You don't employ the vendors, but you hire them. That middle position is exactly where liability likes to land.

When a vendor causes injury or damage, three things determine whether the loss stays with the vendor or flows back to you and the owner:

• Whether the vendor carried the right coverage at the time of the incident
• Whether that coverage names the owner and manager as additional insureds
• Whether you can prove both of the above with documentation

Miss any one of those and you may be absorbing a claim that was never yours to begin with. The certificate of insurance (COI) is the artifact that ties it all together—but a COI is only as good as the coverage behind it and the diligence you apply to collecting and tracking it.

The Core Coverages to Require

Not every vendor needs identical coverage, but these categories cover the vast majority of situations a property manager encounters.

Commercial General Liability (CGL)

This is the foundation. General liability responds to third-party bodily injury and property damage—a visitor who trips over a contractor's equipment, water damage from a botched plumbing repair, a tenant's belongings ruined during a renovation. Require it from essentially every vendor, no exceptions.

Look for occurrence-based coverage rather than claims-made where possible, and pay attention to whether the policy includes products-completed operations, which responds to damage that shows up after the work is finished.

Workers' Compensation

If a vendor's employee is injured on your property and the vendor has no workers' comp, that injured worker may look to the property owner as a responsible party. Workers' comp is mandatory for employers in most states, but enforcement is on you. Require it from any vendor who brings employees onto the property.

Sole proprietors with no employees are a common gray area. Some can legitimately exclude themselves; that's a conversation to have deliberately, in writing, and ideally with your broker's input—not something to wave through.

Commercial Auto Liability

Any vendor driving to, from, or around your property—which is nearly all of them—should carry commercial auto liability. This matters most for vendors operating vehicles on the premises: think snow plows, delivery trucks, or a landscaping crew hauling a trailer through a residential community. "Any auto" or a combination of owned, hired, and non-owned auto coverage is what you're looking for.

Umbrella / Excess Liability

For higher-risk work—roofing, structural work, anything at height, anything involving heavy equipment—an umbrella policy sits on top of the underlying GL and auto limits and extends them. Requiring umbrella coverage scaled to the risk of the job is a reasonable way to make sure a serious claim doesn't blow through a vendor's primary limits and land on the owner.

Professional Liability, When It Applies

Vendors who provide advice or design—architects, engineers, certain consultants—should carry professional liability (errors and omissions). General liability won't respond to a design mistake; E&O will.

Additional Insured and Other Policy Endorsements

Requiring coverage is only half the job. You also need the vendor's policy to actually protect the owner and the management company. That happens through endorsements.

• Additional insured status. The owner and the management company should be named as additional insureds on the vendor's GL (and often auto) policy. This is what lets you tender a claim to the vendor's insurer instead of your own. A certificate that merely lists you in the description box is not the same as a policy endorsement that grants the status—ask for the endorsement form.
• Primary and non-contributory. This language means the vendor's policy pays first and doesn't ask your policy to chip in.
• Waiver of subrogation. This prevents the vendor's insurer from turning around and coming after you to recover what it paid.
• Notice of cancellation. You want to know if a vendor's coverage lapses before their certificate's expiration date.

Your management agreement and the owner's requirements should drive exactly which of these you demand. The point is that "they have insurance" is not the standard—"they have the right insurance, endorsed correctly, in our favor" is.

Setting Sensible Limits

Avoid the temptation to set one blanket limit for everyone. A window-washing service on a high-rise carries a very different risk profile than a vendor restocking vending machines. Instead, tier your requirements:

• Low-risk vendors (interior cleaning, light maintenance, landscaping without heavy equipment): standard general liability limits appropriate to your market.
• Moderate-risk vendors (HVAC, plumbing, electrical, pest control): higher GL limits, confirmed auto coverage, and workers' comp.
• High-risk vendors (roofing, demolition, work at height, crane or heavy-equipment operation): elevated limits plus umbrella coverage.

Set these tiers once, in writing, with your broker's guidance, and apply them consistently. Consistency is what protects you when a claim comes in and someone asks why one vendor was held to a lower standard than another.

A Vendor Insurance Verification Checklist

Requirements only work if you enforce them the same way every time. Use a repeatable process:

1. Set requirements before hiring. Put your coverage types, limits, and endorsement requirements in the vendor contract or work order—not after the crew shows up.
2. Collect the COI before work begins. No certificate, no access. Make this non-negotiable.
3. Verify the coverage matches your requirements. Check that coverage types, limits, and effective dates line up with what you asked for.
4. Confirm additional insured status with the actual endorsement. Don't accept the certificate's description box as proof; request the endorsement form.
5. Check that the certificate is current and the policy is active. A certificate issued eight months ago tells you little about coverage today.
6. Record expiration dates and set renewal reminders. Coverage lapses silently. You need a system that flags a certificate before it expires, not after.
7. Re-collect at every renewal. A vendor who was compliant last year may have dropped coverage or reduced limits.
8. Keep the documentation. If a claim ever arrives, the certificate and endorsements you collected are your evidence that you did your job.

The failure point for most property management operations isn't step one—it's steps six and seven. Certificates pile up in email and file folders, expiration dates slip by unnoticed, and a lapse only surfaces after an incident. Tracking this manually across dozens of vendors and hundreds of certificates is where things break down. A purpose-built system for COI tracking for property managers automates the expiration monitoring and renewal chasing so a lapse gets caught before a vendor ever steps back on site.

The Bottom Line

Vendor insurance enforcement isn't about paperwork for its own sake—it's about making sure that when something goes wrong on a property you manage, the loss lands where it belongs: on the party that caused it, and on their insurer. Require the right coverages, insist on proper additional insured endorsements, tier your limits to the actual risk, and verify everything before work begins. Then keep verifying at every renewal.
