A maintenance contractor responding to a plumbing emergency in a multifamily building turned off the wrong shutoff valve, causing water to flood three occupied units. Damage: $78,000. The contractor-a sole proprietor working under a handyman agreement-had no general liability insurance. The property owner's insurer covered the damage, non-renewed the policy, and the new carrier added a surcharge for water damage claims.
The property manager had worked with this contractor for two years. They had never asked for a certificate of insurance.
This is not an unusual story. Residential property management involves a constant stream of maintenance calls, turn work, and recurring service agreements-and most small residential operations have no formal vendor insurance compliance process at all.
Why Vendor Insurance Matters in Residential Properties
Tenants trust that the people working in and around their homes are qualified and insured. When a vendor's mistake injures a tenant, damages their property, or makes a unit uninhabitable, the tenant's first call is to the property manager-and the property manager's first exposure is determined by whether the vendor was insured.
Beyond tenant claims, consider:
- A landscaper's crew member injured on your property who lacks workers' comp coverage; in many states, the property owner becomes the employer of last resort
- An HVAC contractor who damages a refrigerant line and contaminates common spaces
- A painter who falls from a ladder, and their policy-if it exists-has a residential roofwork exclusion
Uninsured vendor incidents in residential properties routinely produce $50,000-$200,000 in direct losses. Legal fees, tenant relocation, property repair, and insurance consequences compound the exposure.
Vendor Insurance Requirements by Trade
Calibrate requirements to the nature of the work:
Routine Maintenance (Low Risk)
Landscaping, cleaning, painting, pest control, appliance repair:
| Coverage | Minimum |
|---|---|
| General Liability Per Occurrence | $500,000 |
| General Liability Aggregate | $1,000,000 |
| Workers' Compensation | Statutory (if employees) |
| Employers' Liability | $100,000 |
Skilled Trades (Moderate Risk)
Plumbing, electrical, HVAC, roofing, carpentry:
| Coverage | Minimum |
|---|---|
| General Liability Per Occurrence | $1,000,000 |
| General Liability Aggregate | $2,000,000 |
| Workers' Compensation | Statutory |
| Employers' Liability | $500,000 |
| Commercial Auto (if vehicles on-site) | $1,000,000 CSL |
Specialty Contractors (Higher Risk)
Structural repairs, asbestos/lead remediation, elevator service, fire suppression:
| Coverage | Minimum |
|---|---|
| General Liability Per Occurrence | $1,000,000 |
| General Liability Aggregate | $2,000,000 |
| Workers' Compensation | Statutory |
| Employers' Liability | $500,000 |
| Commercial Auto | $1,000,000 CSL |
| Umbrella | $2,000,000 |
| Pollution Liability (where applicable) | $1,000,000 |
For all tiers: require the property owner and management company to be named as additional insureds on the CGL policy, on a primary and non-contributory basis.
The Sole Proprietor Problem
A large percentage of residential maintenance vendors are sole proprietors or very small operators: the independent handyman, the one-person landscaping crew, the informal cleaning service. These vendors often:
- Carry no workers' compensation (may be exempt as sole proprietors in some states, but that exemption doesn't extend to helpers they bring on-site)
- Carry minimal or no general liability insurance
- Operate without formal business entities, making it difficult to enforce claims against them
What to do: Require proof of insurance from every vendor before first work-regardless of business size. A sole proprietor who can't provide a COI is a vendor you can't safely use. The risk transfer mechanism of insurance is not optional.
Many legitimate small vendors do carry proper coverage. Those who don't either need to get it (often inexpensive at their coverage level) or can't be used at your properties.
Building a Pre-Approved Vendor List
The most effective tool for residential property vendor compliance is a pre-approved vendor list:
- Screen vendors once. Require application, license verification, and a compliant COI as a condition of pre-approval.
- Assign work only from the approved list. Maintenance coordinators and on-site managers dispatch from the pre-approved list only.
- Monitor expirations proactively. When a pre-approved vendor's COI expires, they're automatically moved to inactive status until a renewal certificate is verified.
- Annual re-verification. All pre-approved vendors re-submit a current COI annually.
This system eliminates the per-job COI chase and creates a documented record of reasonable care in vendor selection.
Emergency Work Orders and Compliance
The hardest test of any vendor compliance program is the emergency call at 10 PM on a Saturday: a burst pipe, a non-functioning furnace in winter, a broken exterior door lock. Compliance processes routinely break down in these scenarios because the urgency overrides the procedure.
Solution: Emergency vendor pre-approval. Maintain a list of 3-5 pre-approved vendors in each critical trade category (plumbing, electrical, HVAC, locksmith) who are always compliant and available for emergency calls. When an emergency occurs, dispatch from this list only.
For a true exception where no pre-approved vendor is available, get verbal confirmation that the vendor has active coverage, dispatch them, and document the exception in writing with a 24-hour follow-up requirement for the COI.
Documentation Requirements for Every Vendor
For each vendor working at your residential properties, maintain:
- Signed vendor agreement with insurance requirements
- Current COI with all required coverage types and limits
- Additional insured endorsement confirmed
- Policy expiration date logged
- License and contractor registration (where applicable)
- Date of last compliance verification
- Work order history (which vendor worked where, and when)
This documentation is your defense in any insurance dispute or litigation following a vendor-related incident.
The Additional Insured Requirement for Residential Vendors
Just as with commercial properties, residential property owners and managers should be named as additional insureds on every vendor's CGL policy. The additional insured endorsement means that if a vendor's work causes injury or property damage, you have standing under their policy-rather than facing a scenario where their insurer argues the loss isn't covered under your coverage.
For residential properties, the additional insured requirement is often overlooked because many residential vendor agreements are informal. Formalizing vendor agreements-even a simple one-page document-creates the basis for enforcing insurance requirements and documenting additional insured status.
Frequently Asked Questions
Q: Do I need workers' comp coverage for residential vendors who are sole proprietors? A: This is state-specific and fact-specific. In many states, a sole proprietor with no employees is exempt from workers' comp requirements-but if they bring an uninsured helper on-site, that helper may be considered a statutory employee of the property owner. Consult local counsel and require vendors to certify that all workers on-site are covered under their policy.
Q: Can a vendor's homeowner's policy cover their liability while working at my property? A: No. Homeowner's policies specifically exclude business activities. A vendor performing work at your property must have commercial general liability coverage.
Q: How do I handle a vendor who provides a COI but the policy has been canceled since issuance? A: This is more common than people realize-COIs are issued at a moment in time and don't update if the policy lapses. For any new vendor or any vendor before a significant project, call the insurer or broker directly to confirm current active status.
Q: Should I get a separate certificate for each property, or is one portfolio-level certificate acceptable? A: For multi-property portfolios, a portfolio-level certificate may be acceptable if your vendor agreement covers all properties. For specific high-value projects, request a project-specific endorsement listing the individual property address.
