A certificate of insurance is the first document most property managers ask a vendor for, and the one most often misunderstood.
A drawer full of certificates of insurance looks like compliance. It isn’t, unless someone has actually verified what’s on each one. Here’s what a COI proves, what it doesn’t, and what to check before approving any vendor.
What a certificate of insurance actually is
A COI is a summary document, issued by an insurer or their representative, confirming that a policy existed as of the date it was issued. It’s a snapshot, not a guarantee — it doesn’t create coverage on its own, and it can be technically accurate while still leaving you exposed if the underlying policy doesn’t match what you actually need.
What to check on every certificate
Coverage types should match the work being performed. A painting contractor needs general liability; a contractor operating vehicles on your property should also carry commercial auto; anyone with employees should carry workers’ compensation. A certificate showing only general liability when the scope calls for more is incomplete, not just imperfect.
Coverage limits should meet or exceed your property’s requirements — often $1–2 million per occurrence is standard for general contracting work, though your specific requirements may differ by property or ownership group.
Additional insured status matters more than most property managers realize. Unless your management company or ownership entity is specifically named as an additional insured on the vendor’s policy, you may not actually be covered if a claim arises from their work on your property — even if their certificate looks complete.
Effective dates need to be current and shouldn’t lapse mid-project. A certificate that’s valid today but expires before a multi-week project wraps up is a gap waiting to happen.
Get certificates directly from the insurance agent
Ask vendors to have their insurance agent send the COI directly to you rather than forwarding a copy themselves. This isn’t about distrust — it just removes any possibility of an altered or outdated document making it into your files.
Common certificate of insurance mistakes
- Accepting a COI for the wrong entity. The name on the certificate should match the business actually doing the work.
- Ignoring expiration dates. A policy that lapses mid-project leaves you exposed.
- Skipping additional insured status. Without it, you may not be covered for claims arising from the vendor’s work.
- Treating the certificate as coverage. It is a summary, so confirm details with the agent when the stakes are high.
Where to get help
Insurance language can be confusing. The California Department of Insurance publishes consumer resources at insurance.ca.gov, and your own broker can tell you which limits and endorsements your properties should require. When you hire contractors, you can also confirm their license on the CSLB website. See our guide to hiring a licensed general contractor for a full checklist to go with every certificate of insurance.
The bottom line
A certificate of insurance is a starting point, not a finish line. Match coverage types to the work, confirm limits and additional insured status, watch the dates, and get the document from the agent. Build those steps into vendor onboarding and every certificate of insurance in your files will actually mean something.
Build it into onboarding, not just verification
The most effective approach is requiring a compliant COI as a condition of approval before a vendor is added to your approved list — not verifying it after work has already started. Screen once, verify thoroughly, and track renewal dates going forward.
Total Renovation provides current certificates of insurance on request, before any work begins — exactly the kind of documentation your management company or ownership group already expects from any vendor on your properties.
