Property managers deal with more outside vendors than almost anyone else in commercial real estate — landscapers, HVAC techs, plumbers, electricians, roofers, pest control, snow removal, cleaning crews, sometimes a dozen more, often rotating between seasons. Every one of them is a potential liability exposure the moment they set foot on a property you manage. This guide covers what "COI compliant" actually means in practice, and how to keep it that way without it consuming your week.

Why this matters more for property managers than most industries

A general contractor deals with the same subs across the same jobs, over a defined project length. A property manager deals with a rotating cast of vendors across an entire portfolio, on an indefinite basis, some visiting weekly and some once a year. If a landscaper's mower throws a rock through a resident's window, or a maintenance vendor is injured on a ladder in a common area, the first question is the same one every time: was that vendor carrying their own insurance, and can you prove it?

If you can't produce a current certificate, the claim — and the cost — has a real chance of landing on your policy or the property owner's policy instead of the vendor's. Owners, boards, and your own carrier all expect you to have already confirmed vendor coverage before the vendor was ever let onto the property.

Which vendors actually need a COI on file

As a practical rule: any vendor who is not your own employee and who does physical work on or around the property should have a current certificate on file before they start. That includes:

  • Landscaping and grounds maintenance
  • HVAC, plumbing, and electrical contractors
  • Roofing, paving, and other exterior contractors
  • Cleaning and janitorial crews
  • Snow removal (seasonal, easy to let lapse in the off-season)
  • Pest control
  • Security services
  • Any specialty vendor brought in for a one-off repair or capital project

A vendor who only ever mails you an invoice and never sets foot on-site is a lower priority than one whose crew is regularly walking the property — but if there's any chance of them being on-site, default to requiring the certificate.

What to require on the certificate

A certificate that just says "insured" isn't enough. For most property management contracts, that means confirming:

Coverage limits

General liability limits of at least $1 million per occurrence / $2 million aggregate are typical for property-facing vendors; higher for anyone operating heavy equipment or working at height. Workers' comp should be present for any vendor bringing employees on-site — most states require it by law regardless of your contract.

Additional insured status

Where your management agreement or ownership structure calls for it, the property owner (and often the management company) should be named as an additional insured on the vendor's GL policy. This is usually the single most-missed item on vendor certificates — it has to be requested specifically, it doesn't happen automatically.

Waiver of subrogation

For higher-risk vendors (roofing, paving, anything involving heavy equipment), a waiver of subrogation prevents the vendor's insurer from turning around and suing the property owner to recover a payout. Not every contract needs this, but it's worth requiring for anything with real injury or property-damage risk.

Expiration date

The single most common compliance failure isn't a missing certificate — it's an expired one that was correct when it was collected and nobody noticed had lapsed eight months later.

Keeping it current across a whole portfolio

Collecting a certificate once, at onboarding, solves the problem for exactly as long as that policy stays in force — typically 6 to 12 months. After that, you're relying on someone remembering to re-check every vendor across every property on a rolling basis, which is where manual tracking breaks down. Across a portfolio of any real size, that's dozens of renewal dates spread across the calendar, each one requiring its own follow-up email to an agent who may or may not respond on the first try.

The practical fix is the same one used for tracking subcontractor certificates on the contracting side: a system that watches renewal dates automatically and emails the vendor's agent directly as each one approaches, instead of relying on a property manager to remember sixty separate dates. CertWatch was built for exactly this — add each vendor once with their agent's email and renewal date, and it handles the monitoring and follow-up from there, notifying you the moment a current certificate is back on file.

A simple compliance checklist

  • Every vendor who works on-site has a current certificate on file before their first visit.
  • Coverage limits meet your management agreement's minimums.
  • Additional insured status is confirmed where required, not assumed.
  • Renewal dates are tracked automatically, not on a manually-checked spreadsheet.
  • Follow-up on an approaching or passed renewal date happens without you having to remember to send it.
