Subcontractor Insurance Requirements: What General Contractors Should Track

General contractors may need to keep track of required coverage types, policy limits, effective and expiration dates, additional insured requirements, waivers of subrogation, endorsements, and other project-specific requirements.

The exact insurance requirements can vary by contract, project, company, jurisdiction, and the work being performed. But once those requirements have been established, construction teams need a reliable way to document them and keep the supporting insurance information current.

What Are Subcontractor Insurance Requirements?

Subcontractor insurance requirements define the insurance coverage and related documentation a subcontractor is expected to maintain for a project or business relationship.

These requirements may be established in a subcontract, master service agreement, company insurance standard, owner requirement, or other project documentation.

A requirement may specify more than simply whether a subcontractor carries a particular type of insurance. It can also address coverage limits, policy dates, endorsements, additional insured status, waiver of subrogation, and other conditions.

That is why collecting a COI is only one part of the process.

Who Determines the Insurance Requirements for a Subcontractor?

There is no single set of insurance requirements that applies to every subcontractor or every construction project.

Requirements may be influenced by the contract, project owner, general contractor, insurance or risk advisors, jurisdiction, scope of work, and other project-specific considerations.

Construction teams should rely on the requirements established for their own projects rather than treating a generic checklist or another company's requirements as a substitute for appropriate insurance guidance.

Once those requirements are established, however, they need to be communicated, documented, reviewed, and monitored consistently.

Common Types of Subcontractor Insurance Requirements

The specific coverage required varies, but construction teams commonly encounter several types of insurance when managing subcontractor records.

General Liability

Commercial general liability coverage is commonly included in subcontractor insurance requirements.

A requirement may identify applicable limits and may also include conditions involving additional insured status, endorsements, or other contractual provisions.

Auto Liability

Auto liability requirements may apply when subcontractors use vehicles in connection with their work.

The appropriate requirements depend on the contract and the nature of the work being performed.

Workers' Compensation

Workers' compensation documentation may be part of a subcontractor's insurance requirements.

Requirements and applicable rules can vary by jurisdiction and circumstances, making it important for construction teams to follow the standards established for the particular project and subcontractor.

Umbrella or Excess Liability

Some contracts or projects may require umbrella or excess liability coverage in addition to underlying policies.

When this coverage is required, teams may need to track the policy information, limits, and dates along with the subcontractor's other insurance records.

Employers' Liability

Employers' liability may also appear within a project's insurance requirements and should be tracked according to the requirements established for that subcontractor.

Coverage Limits Are Only Part of the Requirement

One common mistake is focusing exclusively on policy limits.

Limits matter, but they may represent only one part of the insurance requirement.

Depending on the contract or project, construction teams may also need to track:

• Coverage type
• Policy number
• Effective date
• Expiration date
• Insurer information
• Required limits
• Additional insured requirements
• Waiver of subrogation requirements
• Required endorsements
• Certificate holder information
• Project-specific requirements
• Supporting documents
• Notes or exceptions

A subcontractor can therefore have a COI on file without the documentation necessarily demonstrating that every project requirement has been addressed.

A COI on file is not automatically the same thing as compliance with the project's insurance requirements.

Additional Insured and Waiver of Subrogation Requirements

Additional insured and waiver of subrogation requirements frequently create confusion because they cannot always be evaluated simply by seeing a name or checkbox on a certificate.

Being listed as the certificate holder, for example, does not by itself make that party an additional insured.

Additional insured status generally depends on the underlying policy and applicable endorsement rather than the certificate itself.

Similarly, if a waiver of subrogation is required, construction teams may need supporting documentation appropriate to that requirement.

For a deeper explanation of one of these distinctions, see Additional Insured vs. Certificate Holder: What's the Difference?

What a Certificate of Insurance Can—and Cannot—Confirm

A certificate of insurance provides useful information about insurance policies in effect when the certificate is issued.

It can help construction teams identify information such as:

• Named insured
• Insurance carrier
• Policy number
• Coverage type
• Policy effective and expiration dates
• Policy limits
• Certificate holder
• Certain descriptions or remarks

But the certificate itself does not replace the underlying policy or endorsements, and it does not create coverage.

That distinction matters when a contract requires documentation or policy provisions that cannot be established by the COI alone.

The goal should not simply be “Do we have a certificate?”

The better question is:

“Do we have the information and documentation required for this subcontractor and this project?”

Why Insurance Requirements May Differ by Project

A subcontractor that works on several projects may not necessarily have identical insurance requirements for every project.

Different owners, contracts, scopes of work, or project conditions can result in different requirements.

That creates an important tracking challenge.

If a company only stores one COI under the subcontractor's name, employees may have difficulty determining which documentation applies to which project and whether project-specific requirements have been addressed.

Project-level organization helps preserve the relationship between the subcontractor, its insurance documentation, and the requirements associated with the work.

What General Contractors Should Track for Each Subcontractor

Once insurance requirements have been established, the general contractor needs a consistent way to track both the requirements and the supporting documentation.

At a minimum, the process may need to capture:

• Subcontractor name and contact information
• Project or subcontract
• Required insurance coverage
• Required limits
• Policy information
• Effective and expiration dates
• Additional insured requirements
• Waiver of subrogation requirements
• Endorsements or supporting documentation
• Missing information
• Follow-up activity
• Current status
• Notes or exceptions

The exact fields will depend on the company's process, but consistency is important.

If one employee tracks expiration dates in a spreadsheet, another stores endorsements in email, and a third keeps project requirements in a separate folder, it becomes difficult to see the complete record.

What Happens When Documentation Is Missing or Out of Date?

Missing documentation does not always mean the same thing.

A COI may be missing entirely. A policy may have expired. A renewed certificate may not yet have been received. An endorsement may still be outstanding. Information on the certificate may not match the requirements being tracked.

Those situations should not automatically be treated as identical.

A useful process identifies what is missing or needs attention so the appropriate person can follow up according to the company's procedures and contractual requirements.

When a policy or COI expires during active work, the response may depend on the contract, project requirements, company procedures, and the subcontractor's current coverage.

For more on that situation, see What Happens When a Subcontractor's COI Expires During a Project?

Why Spreadsheets Make Subcontractor Requirements Harder to Manage

Spreadsheets can be useful when a company has a small number of subcontractors and relatively simple tracking needs.

The difficulty increases as the number of projects, subcontractors, policies, documents, and renewal dates grows.

A spreadsheet may tell an employee that a policy expires on a particular date, but the surrounding process often still depends on people remembering to:

• Check upcoming expirations
• Request renewed certificates
• Save updated documents
• Update spreadsheet fields
• Locate endorsements
• Review project-specific requirements
• Record follow-up activity
• Tell other team members what changed

The problem is not necessarily the spreadsheet itself. It is the amount of manual coordination required around it.

A Practical Subcontractor Insurance Review Process

A consistent review process can make subcontractor insurance requirements easier to manage.

Step 1: Define the Requirements

Document the insurance requirements that apply to the subcontractor and project before evaluating the insurance records.

Step 2: Collect the Documentation

Gather the COI and any supporting documentation required by the contract or company process.

Step 3: Review the Information

Compare the information provided with the requirements that have been established for the subcontractor and project.

Step 4: Identify Missing or Unresolved Items

Record anything that requires additional documentation, clarification, or follow-up.

Step 5: Maintain the Record

Keep the relevant documentation, requirement information, notes, and history organized in a location accessible to the appropriate team members.

Step 6: Monitor Expiration Dates

Track policy expiration dates and begin renewal follow-up before current documentation becomes outdated.

Step 7: Review Changes

If the project, contract, scope of work, or insurance requirements change, update the record rather than assuming the original requirements still apply.

The goal is a repeatable process—not a one-time certificate collection exercise.

Where My Smart COI Tracker Fits

My Smart COI Tracker is designed for construction teams that need a simpler way to organize and monitor certificates of insurance.

Teams can keep subcontractor and project records organized, store COI documents, track policy expiration dates, use automated reminders, and maintain visibility into records that need attention.

AI-assisted document scanning can also reduce some of the manual data entry involved in recording COI information.

The goal is to give construction teams a more organized system for managing COI information without adding unnecessary enterprise complexity.

As with any tracking tool, the company remains responsible for establishing its insurance requirements and determining whether the documentation provided satisfies those requirements.

Frequently Asked Questions

Final Thoughts

Subcontractor insurance management is not simply a matter of collecting a COI and checking a box.

Construction teams may need to understand what insurance requirements apply, collect the appropriate documentation, review the information provided, identify unresolved items, and continue monitoring policy dates throughout the relationship.

A consistent process makes that work easier to manage and gives teams better visibility into what is current, what is missing, and what needs attention.

The certificate is evidence. The requirement is the standard it needs to be evaluated against.
