HOA Vendor Insurance Requirements: Limits and Endorsements by Trade (2026)

HOA vendor insurance requirements should include three baseline coverages from every contractor who sets foot on the property: commercial general liability at $1 million per occurrence and $2 million aggregate, statutory workers compensation, and commercial auto at $1 million combined single limit. Most boards get those minimums right but never check the endorsement layer underneath, where coverage actually transfers to the association. This guide covers the specific limits each trade should carry, the four endorsements that matter, and how to verify that vendor certificates match what your HOA insurance program governing documents require.

What insurance should your HOA require from every vendor?

Every vendor working on HOA common areas needs three active policies before starting any job: commercial general liability (GL), workers compensation (WC), and commercial auto. GL covers property damage and bodily injury caused by the vendor's work on common areas. Workers comp is the one most small contractors try to skip, and it covers their own employees if someone gets hurt on association property. Commercial auto covers vehicles the vendor drives through the community.

Without workers comp, your association becomes the deep pocket. Most states hold the hiring entity liable for workplace injuries when the contractor lacks coverage, and that means the HOA pays medical bills and lost wages from operating funds or reserves.

The floor that works for most associations: $1M per occurrence and $2M aggregate on GL, statutory limits on workers comp (set by your state), and $1M combined single limit on commercial auto. Higher-risk trades need more, and the next section lays that out by trade. The certificate of insurance (COI) the vendor hands you confirms those limits exist, but it doesn't confirm the association has any rights under the policy.

How much coverage does each trade need?

How much GL coverage each vendor should carry depends on the risk their trade creates. A landscaper creates far less exposure than a roofer on a four-story building. (The roofer's carrier prices that gap into the premium, and your minimum requirements should reflect the same logic.) The table below sets minimum limits by trade based on standard industry practice and what we recommend for the HOA portfolios we handle.

What endorsements should you demand beyond the COI?

Four endorsements turn a vendor's policy into real protection for your association. Without them, the certificate of insurance only confirms the vendor bought a policy. It says nothing about whether your HOA can file a claim on it.

Additional insured (endorsement forms CG 20 10 for ongoing operations and CG 20 37 for completed operations) names the HOA on the vendor's GL policy. The association can file claims directly. CG 20 10 protects the association while the vendor is on-site. CG 20 37 protects it after the work is finished, when a defect surfaces months later.

Waiver of subrogation prevents the vendor's insurer from suing your HOA to recover money it paid on a claim. Without this endorsement, the vendor's carrier could pay an injured resident and then turn around and sue the association to recoup its costs. (Yes, the vendor's own insurer suing the HOA is a real thing.) Require waiver of subrogation on both GL and workers comp policies.

For any HOA vendor relationship, additional insured and waiver of subrogation are the two non-negotiable endorsements.

Primary and non-contributory wording means the vendor's policy pays first if a claim arises, before your HOA's insurance contributes anything. Without it, the association's carrier may have to split defense costs with the vendor's insurer.

Also require 30-day advance written notice of cancellation so the board knows immediately if a vendor's coverage lapses mid-contract.

Why does the COI checkbox not mean you are covered?

A certificate of insurance (the standard ACORD 25 form) is a snapshot of what coverage the vendor carried on the date it was issued. It isn't a contract. It doesn't grant the HOA any rights under the vendor's policy. The checkboxes on the ACORD 25 for "additional insured" and "waiver of subrogation" are informational only.

The only document that gives the HOA actual coverage is the endorsement attached to the vendor's policy. A vendor can hand you a certificate with every box checked. If the endorsement was never added to the underlying policy, the association has zero claim rights when something goes wrong.

There is also a difference between endorsement forms worth knowing. The blanket form CG 20 26 adds additional insured status only "as required by written contract." Your vendor insurance clause has to be airtight, or the carrier can argue the contract language didn't trigger coverage. Forms CG 20 10 and CG 20 37 are more specific and harder for a carrier to dispute at claim time.

What happens if your vendor has no insurance?

When an uninsured vendor causes property damage or injures a resident on common areas, the association's own GL policy becomes the first line of defense. That claim hits the HOA's loss history and drives up premiums at renewal. A single vendor-caused injury claim can increase the association's GL premium by 15% to 30% at the next renewal cycle.

If the claim exceeds the HOA's policy limits, the board may need to levy a special assessment against homeowners to cover the gap. In a 200-unit association, a $500,000 uncovered claim works out to $2,500 per unit, and that kind of bill gets board members voted out at the next annual meeting.

Board members also face personal exposure. If homeowners can show the board failed to enforce its own vendor insurance requirements, that failure can support a breach of fiduciary duty claim against individual directors. Vendor theft on association property is a separate risk covered under the HOA's crime and fidelity policy. A mishandled vendor contract is also one of the most common property manager E&O claim triggers.

How do you verify vendor coverage before work starts?

Verification takes more than a quick glance at the certificate. Before any vendor starts work, request the ACORD 25 certificate plus copies of the actual endorsement pages showing additional insured status, waiver of subrogation, and primary and non-contributory wording.

Match the limits on the certificate against your association's minimum requirements by trade using the table above. Confirm the HOA's full legal entity name is spelled correctly on the additional insured endorsement, because carriers reject claims when the named entity doesn't match character for character.

Track every vendor's policy expiration date and require updated certificates 30 days before each renewal. A vendor whose policy lapsed three months ago is effectively uninsured, and the original certificate gives you no indication of that.

For associations and management companies handling dozens of vendor relationships, Coverwatch manages COI collection, endorsement verification, and renewal tracking to keep HOA vendor insurance requirements current across the full vendor roster. Management companies running multiple communities can consolidate vendor compliance into a single review, which is one less item eating up the next board meeting.
