A property management company hired a new landscaping contractor for their portfolio of six apartment communities. The contractor signed a service agreement that specified commercial general liability coverage of $1 million per occurrence and named the property owner as additional insured. The contractor submitted a COI. The property manager filed it. Two months later, a landscaping crew member fell off a mower on a hillside at one of the properties, sustaining a serious injury. The contractor's workers' compensation coverage was current. But when the incident report was reviewed, the claim adjuster noticed that the contractor's CGL policy had a residential landscaping exclusion that the property manager had not caught - because no one had verified the submitted COI against the service agreement provisions or reviewed the underlying policy for exclusions that would affect coverage.
The gap cost the property owner $78,000 in direct costs and a lengthy subrogation dispute with the contractor's insurer. All of it was preventable with a more thorough initial verification.
All Vendors Serving Residential Properties
The vendor landscape for a residential property - even a single property - is typically broader than operators initially recognize. A realistic vendor list for a 100-unit apartment community includes:
| Vendor Category | Risk Profile | Work Frequency |
|---|---|---|
| General contractor/renovation | High - structural, bodily injury, property damage | Project-based |
| HVAC contractor | High - hazardous equipment, fire risk | Monthly/as needed |
| Plumbing contractor | Medium-High - water damage risk | As needed |
| Electrical contractor | High - fire and electrocution risk | As needed |
| Landscaping/grounds | Medium - slip/trip, equipment injury | Weekly |
| Pest control | Medium - chemical exposure, liability | Monthly/quarterly |
| Cleaning services | Medium - slip/fall, property damage | Weekly or daily |
| Security/access control | Medium - liability for incidents | Monitoring + periodic service |
| Elevator maintenance | High - bodily injury from mechanical failure | Monthly |
| Pool/spa service | High - drowning, chemical, slip risk | Weekly |
| Snow removal | High - slip/fall risk, property damage | Seasonal |
| Waste/recycling service | Low-Medium - standard injury risk | Weekly |
| Telecom/cable installation | Medium - property damage, bodily injury | As needed |
For each of these vendor categories, the property manager has two obligations: establishing the right insurance requirements in the service agreement, and verifying that submitted COIs actually meet those requirements.
Insurance Requirements by Vendor Type
The appropriate insurance requirements for vendors differ by the nature of the work, the frequency of on-site presence, and the scale of potential incidents. A cleaning service working in common areas needs different coverage than a general contractor undertaking a $400,000 renovation project.
High-risk vendors (contractors, HVAC, electrical, structural):
| Coverage Type | Minimum Requirement |
|---|---|
| Commercial general liability | $2 million per occurrence / $4 million aggregate |
| Workers' compensation | Statutory limits (mandatory for any vendor with employees) |
| Automobile liability | $1 million combined single limit |
| Umbrella/excess | $5 million following form |
| Additional insured | Property owner and management company |
| Waiver of subrogation | Required in favor of property owner |
| Primary and non-contributory | Required in COI and endorsement |
Medium-risk vendors (landscaping, cleaning, pest control, pool service):
| Coverage Type | Minimum Requirement |
|---|---|
| Commercial general liability | $1 million per occurrence / $2 million aggregate |
| Workers' compensation | Statutory limits |
| Automobile liability | $1 million (if vehicles used) |
| Additional insured | Property owner and management company |
| Waiver of subrogation | Recommended |
Lower-risk service vendors (waste, telecom, monitoring):
| Coverage Type | Minimum Requirement |
|---|---|
| Commercial general liability | $500,000-$1 million per occurrence |
| Workers' compensation | Statutory limits |
| Additional insured | Property owner and management company |
These are baseline frameworks. Service agreements should specify requirements appropriate to the actual scope of work, and requirements should be reviewed when the scope changes materially (e.g., a cleaning vendor taking on additional services, a landscaping vendor adding hardscape installation).
The Additional Insured Requirement in Vendor Agreements
The additional insured requirement is present in most residential property vendor agreements, but its practical effect depends entirely on whether it is properly implemented in the vendor's actual policy - not just checked on the COI form.
The most common additional insured failure in vendor COIs for residential properties is the distinction between:
A COI notation. The vendor's agent checks the additional insured box on the ACORD 25 form and types the property owner's name. This creates a representation that AI status exists but does not create the endorsement. If no AI endorsement is on the underlying policy, the property owner has no direct rights under the vendor's coverage.
An actual endorsement. The vendor's policy has a blanket additional insured endorsement (such as ISO CG 20 37) or a specifically scheduled endorsement naming the property owner. This creates actual AI status with coverage rights.
The verification of additional insured status requires more than reading the ACORD form. For vendors performing ongoing work at the property, the verification should confirm that an AI endorsement is actually on the underlying policy. This typically requires either the endorsement itself as supplemental documentation or a carrier confirmation.
For high-risk vendors - contractors, HVAC, electrical - this additional step is worth requiring. For lower-risk recurring service vendors, a blanket AI endorsement confirmation in the service agreement and an ACORD notation is often a practical middle ground.
How to Verify Compliance Before Allowing Work
The verification sequence for residential vendor COIs should be integrated into the vendor onboarding workflow so that work authorization does not happen until compliance is confirmed:
Step 1: Request COI at contract execution. Do not wait until the vendor shows up to begin work. The COI request should be part of the contract execution workflow, with a clear communication that work cannot begin until a compliant COI is on file.
Step 2: Compare against contract requirements. When the COI is received, compare it against the insurance requirements in the service agreement. Check coverage types, limits, policy period, additional insured designations, and waiver of subrogation provisions.
Step 3: Flag any deficiencies. If the submitted COI does not meet requirements, generate a deficiency notice that identifies the specific gaps (not just "your COI is insufficient" but "your CGL per-occurrence limit is $500K; the contract requires $1M").
Step 4: Request corrected COI. Send the deficiency notice to the vendor and request a corrected COI addressing the specific gaps. If the vendor cannot meet the requirements, this is the point to determine whether the requirement can be adjusted or whether a different vendor is needed.
Step 5: Confirm compliance and authorize work. When a corrected, compliant COI is received, log the confirmation and issue work authorization. The authorization should be conditional on the COI remaining current - if the policy expires during the work engagement, the vendor must submit a renewal COI before work continues.
Non-Compliance Response
When a vendor fails to provide a compliant COI, the response options depend on the urgency of the work and the nature of the gap.
For non-urgent work: suspend work authorization pending receipt of a compliant COI. Most vendors who operate professionally will resolve COI deficiencies quickly when they understand that the deficiency is blocking a paid engagement.
For urgent work (emergency repairs, time-sensitive projects): a conditional work authorization with a short window (24-72 hours) to provide a compliant COI is sometimes appropriate. Document the authorization, the specific gap, and the timeline for resolution. Do not allow the conditional period to extend indefinitely.
For vendors who consistently fail to maintain adequate coverage: this is a qualification issue. A vendor who cannot maintain the required insurance is not an appropriate vendor for the property program, regardless of price or convenience.
Bramble's vendor COI compliance platform enables residential property managers to run automated contract-to-COI comparison for every vendor submission - catching deficiencies before work begins rather than after an incident.
