COI Requirements for Property Managers and Vendors

By SubCover HQ · Updated Oct 27, 2026 · 4 min read

Property managers deal with a constant stream of outside vendors: landscapers, snow removal, cleaners, plumbers, HVAC techs, roofers, elevator contractors, pest control, movers, and one-off handymen. Every one of them is a potential claim against the owner and the management company if something goes wrong. A clear vendor COI program is one of the simplest ways to protect both.

Why vendor COIs matter more in property management

• Occupied buildings. Tenants, residents, and visitors are on site while vendors work, so third-party injury and property damage risk is higher.
• Two parties to protect. The ownership entity (often a single-asset LLC) and the management company both need protection, and management agreements often require it.
• Lots of small vendors. Many are small businesses that let policies lapse or carry minimal coverage.
• Recurring work. A landscaper you hired three years ago may have changed insurers twice since.

Build a vendor requirements standard

Work with your broker, and check what your management agreements and the owners' insurance require. A typical vendor standard covers:

• General liability with limits appropriate to the work. $1M per occurrence and $2M aggregate is common for routine vendors, with umbrella coverage for higher-risk work like roofing, tree removal, or elevator service. (See common limits.)
• Commercial auto for any vendor driving onto the property.
• Workers' compensation and employers' liability, or a documented exemption if the vendor legitimately has no employees and your policy allows it. An uninsured vendor's injured worker can become your problem.
• Additional insured status for both the ownership entity and the management company, using exact legal names.
• Waiver of subrogation and primary and noncontributory wording where required.
• Trade-specific coverage: pollution for pest control or environmental work, professional liability for engineers and consultants, garage keepers for parking operators, and so on.

Get the names right

The most common property management COI problem is the wrong names. Before you send requirements to any vendor, document for each property:

• The exact legal name of the ownership entity (for example, "123 Main Street Owner LLC," not "123 Main").
• The exact legal name of the management company.
• Any lender or association that must also be named.
• The certificate holder name and mailing address you want used.

Put this in a per-property requirements sheet so every vendor gets the same instructions. Our additional insured vs. certificate holder guide explains why both matter.

Make compliance a condition of work

• No vendor setup in your accounts payable system without an approved COI.
• No work orders issued to vendors with expired or deficient coverage.
• Building staff and site managers know how to check vendor status before letting anyone in.
• Your vendor agreements require the insurance, indemnity, and notice of cancellation where possible.

Track every vendor, every policy, every property

The hard part is keeping it current across a portfolio. A vendor that works at 12 properties may need a certificate that lists 12 ownership entities, or separate certificates per property. Track:

• Each policy's expiration date, separately.
• Which properties the vendor serves, and whether each property's entities are covered.
• Endorsements on file.
• The vendor's insurance agent contact, for fast renewals.

Chase renewals 30 days ahead, follow up at 14 and 7 days, and mark vendors inactive when coverage lapses. Our COI tracking guide lays out the full schedule.

Handling one-off and emergency vendors

Burst pipe at 2 a.m.? Have a short list of pre-approved emergency vendors with current COIs on file, so you're not choosing between compliance and a flooded unit. For true one-off jobs, require a COI before work and payment, even for small tickets.

What about tenants' contractors?

Tenants often hire their own contractors for buildouts or installs. Your lease likely gives you the right to require those contractors to carry insurance and name the landlord and manager as additional insureds. Apply the same standard and the same tracking.

A done-for-you option

SubCover HQ handles vendor COIs for property managers end to end: we request certificates from each vendor's agent with your per-property names, check them against your requirements, track every expiration, and chase renewals, so your team isn't spending its week on certificate emails.

Frequently asked questions

Should requirements differ by vendor type?

Yes. Most managers use tiers: lower requirements for low-risk services like window washing on the ground floor or office supply delivery, and higher ones for roofing, tree work, elevator service, and anything involving heights, heavy equipment, or hazardous materials.

Who should be the certificate holder?

Usually the management company, at the address where you process compliance documents, with the ownership entity and management company both named as additional insureds. Some owners prefer to be the certificate holder themselves. Follow your management agreement.

What if a vendor serves dozens of properties?

Ask the agent whether the vendor's policy has a blanket additional insured endorsement covering anyone required by written contract. If it does, one certificate referencing the blanket endorsement may be acceptable, combined with signed contracts for each property. If not, you may need certificates per ownership entity.

How do I handle vendors that push back?

Explain that the requirements are standard and apply to every vendor. Send the exact wording to their agent, who handles these requests every day. Most pushback ends when the vendor realizes the agent can turn a certificate around in a day.

Key takeaways

Name the right entities, set tiered requirements per property, make an approved COI a condition of any work order, and track each policy date. Consistency matters more than perfection: the same rules for every vendor, every time.
