Commercial Tenant Certificates of Insurance: What Landlords and Property Managers Should Require

By SubCover HQ · Updated Oct 29, 2026 · 3 min read

Vendors come and go, but a commercial tenant may be in your building for ten years. Most commercial leases require the tenant to carry insurance and name the landlord and manager as additional insureds. The trouble is keeping proof of that coverage current year after year. Here's what to require and how to keep it from slipping.

How tenant COIs differ from vendor COIs

What leases commonly require

Every lease is different, so treat this as a list of things to look for, not a standard:

The ACORD forms you'll see

Liability coverage usually comes on an ACORD 25. Property coverage and loss payee or mortgagee interests are typically shown on an ACORD 28 (evidence of commercial property insurance). See ACORD 25 vs. ACORD 28 for the difference.

Where tenant compliance breaks down

A simple tenant COI process

  1. Abstract each lease's insurance terms into a short requirement list per tenant.
  2. Request certificates from the tenant's agent, with the exact names for additional insureds and the certificate holder.
  3. Check each certificate against that tenant's list, not a generic standard.
  4. Track every policy's expiration separately and request renewals 30 days ahead.
  5. Re-send requirements after any ownership, lender, or management change.
  6. Require certificates from the tenant's contractors before any buildout or alteration starts.

Our free COI expiration tracker handles a few tenants, and the COI request letter generator drafts the request. For a full portfolio, SubCover HQ collects tenant and vendor certificates, checks them against each lease's terms, and chases renewals for you.
