Avoid Five Figure Audit: Contractor Insurance Checklist for Landlords
Every contractor and vendor working on your rental should carry general liability, workers’ compensation, and commercial auto coverage, with umbrella liability layered on for higher-risk jobs and professional liability required for design or engineering work. A common baseline is $1 million per occurrence and $2 million aggregate, scaled up for roofing, structural, or large renovation projects. Before anyone picks up a tool, collect an ACORD 25 certificate of insurance and confirm the additional insured endorsement actually exists on the underlying policy. That single step is what separates landlords who sail through an audit from those who get hit with a surprise bill.
TL;DR:
Contractors should carry at least $1 million per occurrence and $2 million in total coverage, with higher limits for large or structural projects.
Verifying both the certificate of insurance and the actual endorsement is essential, requiring direct calls to the insurer for confirmation.
Insurance clauses, including minimum coverage, additional insured status, and waiver of subrogation, must be built into vendor contracts before work begins.
Relying solely on a certificate without verifying endorsements or requiring proof before starting work exposes landlords to audit risks and uncovered liabilities.
Using property management services or automated tools can streamline vendor insurance verification and help prevent costly audit surprises.

What Insurance Coverage Should You Require From Contractors?
Contractor insurance requirements start with commercial general liability, or CGL. This policy covers bodily injury and property damage a contractor’s work causes on your property, whether that’s a plumber flooding a unit or a painter cracking a window. A baseline of $1 million per occurrence and $2 million aggregate is standard for most residential maintenance and repair work, and it’s the figure most vendors already carry.
Workers’ compensation matters just as much, even for one-person operations. Requiring it protects you from being treated as the employer of record if a worker gets hurt on your property, and it shields you from audit exposure tied to misclassified subcontractors. Skip this check and you’re gambling with your own payroll records.
A few other coverages round out a solid contractor insurance policy:
Commercial auto: required whenever a vendor drives a company vehicle to your property, hauls materials, or transports equipment between job sites.
Professional liability: necessary for architects, engineers, or anyone providing design work, since CGL doesn’t cover errors in professional judgment.
Umbrella or excess liability: worth requiring for roofing crews, structural contractors, or large-scale renovation projects where a single claim could blow through a standard CGL limit.
Maintaining appropriate liability limits and layering umbrella coverage on higher-risk jobs is standard advice among property managers, and it costs you nothing since the contractor carries the policy. Match the coverage to the job. A handyman replacing a faucet doesn’t need the same limits as a crew reframing a roof.
How Do You Read and Verify a Certificate of Insurance?
A certificate of insurance is a snapshot, not a contract. The ACORD 25 form is informational only, meaning it tells you what a contractor’s insurance agent claims is in force, not what rights you actually hold. That distinction trips up more landlords than any other part of the process.
Here’s how to actually verify one:
Check the insured name against the contractor’s legal business entity, not a DBA or a name that doesn’t match your contract.
Confirm the certificate holder line lists you or your property management entity, not a different company.
Review each policy row for type (CGL, workers’ comp, auto), limits, and both the effective and expiration dates.
Look for endorsement language in the description box, specifically additional insured status and waiver of subrogation.
Call the issuing agent directly using the contact information on the certificate, and ask for a copy of the actual endorsement, not just a verbal confirmation.
Endorsements matter because they’re what physically alters the underlying policy. An additional insured endorsement extends coverage to you as a named party. A waiver of subrogation stops the contractor’s insurer from coming after you after paying a claim. Without those endorsements attached, a COI is little more than a promise with no legal teeth.
Watch for red flags: expired dates, a certificate-only policy with no endorsement backing it, a mismatched legal entity, or an agent who won’t provide documentation beyond the certificate itself.
Pro Tip: Ask for the endorsement by form number, like CG 20 10 for additional insured on a commercial general liability policy. Agents recognize the request instantly, and vague requests get vague answers.
What Contract Language Locks In Insurance Compliance?
Verification only works if your vendor agreement requires it. Build these clauses into every contractor and vendor contract before work begins:
Minimum coverage and limits clause, spelling out exactly which policies and dollar amounts you require.
Additional insured clause, naming you or your property management entity on the contractor’s CGL policy.
Waiver of subrogation clause, blocking the contractor’s insurer from pursuing you after a claim payout.
Hold harmless or indemnity provision, shifting liability for the contractor’s own negligence back to them.
Flow-down requirement, forcing a general contractor to pass these same standards to every subcontractor on the job.
On the administrative side, require the COI before the contractor sets foot on the property, not after. Designate one person, whether that’s you or your property manager, to collect and file certificates centrally. Set a recurring reminder to re-verify coverage before each policy’s expiration date. Make insurance compliance a condition of final payment, not an afterthought you chase down later. If you’re hiring a general contractor who brings in subs, hold the GC contractually responsible for verifying every sub’s coverage, not just their own.
What Happens When You Skip Verification?
The most expensive mistake landlords make is assuming a handshake or a verbal “yeah, I’m insured” is good enough. It isn’t, and the bill for that assumption usually arrives during a workers’ compensation audit, not while the work is happening.
Here’s the mechanism: if you can’t produce a COI at your annual workers’ comp premium audit, the auditor treats payments to that uninsured contractor as payroll and charges you premium on it retroactively. A landlord who paid a handyman $15,000 over a year for repairs could see that entire amount reclassified as wages, with premium calculated as if that person were a direct employee.
Beyond the audit risk, you’re exposed to uncovered medical costs if that worker gets hurt with no workers’ comp backing them, and you could face denial of coverage under your own landlord policy if a claim traces back to an uninsured vendor.
Quick mitigations that actually work:
Never let work start without a current COI on file.
Verify the endorsement, not just the certificate.
Require general contractors to flow insurance requirements down to every sub, in writing.
A documented collect-and-verify process before work starts remains the cheapest defense against a five-figure surprise audit bill.
A Ready-to-Use Contractor Insurance Checklist
Run through this sequence before any vendor starts work on your property:
Signed vendor contract with insurance clauses, indemnity language, and flow-down requirements in place.
Current COI (ACORD 25) naming your entity as certificate holder.
Endorsement copy confirming additional insured and waiver of subrogation.
Agent contact verification, confirming the certificate came from a real, licensed source.
Effective date check, confirming coverage is active through the projected job completion date.
Filed and logged, with a renewal reminder set before expiration.
If any item is missing, contact the contractor’s insurance agent directly, not the contractor. Pause the job until you have documentation in hand. This checklist matters most for planned renovations and recurring vendors. A small emergency repair, like a burst pipe at midnight, doesn’t always allow time for full verification before the work starts, but you should still collect the COI within a day or two and treat that vendor’s future jobs as contingent on it.
Pro Tip: Keep a simple spreadsheet with contractor name, policy expiration dates, and endorsement status. A five-minute monthly scan catches lapses before they become audit problems.
A Property Manager’s Take on Contractor Insurance
Handling contractor certificates day to day teaches you fast that the paperwork isn’t busywork. Verifying COIs and endorsements before a vendor sets foot on a property is a standing recommendation for onboarding every contractor, and it can help clients avoid audit surprises like those described above.
The habit that pays off most is separating certificate collection from endorsement verification. A lot of landlords stop at the COI and assume the job is done. It isn’t. Call the agent, ask for the endorsement, and file it before the first invoice gets paid.

FAQ
What is the minimum general liability limit to require from contractors?
A common baseline is $1 million per occurrence and $2 million aggregate, though you should require higher limits or umbrella coverage for roofing, structural, or large renovation jobs.
Why does a COI alone not protect you as a landlord?
A certificate of insurance is informational only. The additional insured endorsement on the underlying policy is what actually extends coverage rights to you.
Should you require workers’ compensation from a one-person contracting business?
Yes. Sole proprietors are often exempt from carrying it by law, but skipping the requirement leaves you exposed to misclassification and audit risk if that worker gets hurt on your property.
What happens if a contractor’s COI expires mid-project?
Work should pause until an updated certificate and endorsement are on file, since coverage gaps during active work leave you liable for any incident that occurs while the policy is lapsed.
Can a property manager handle contractor insurance verification for you?
Yes. Property managers like 2nd Street Property Management routinely build COI collection, endorsement verification, and renewal tracking into standard vendor onboarding for landlords who don’t want to manage it themselves.
