Insurance might not be the first thing you think about when hiring a general contractor, but in New York City, it should be. With strict building regulations, complex job sites, and layered liability, a contractor’s insurance coverage can directly affect your project’s timeline, budget, and exposure to risk.
This guide explains what types of coverage to look for, how to read a Certificate of Insurance (COI), and what to ask before work begins—so you can move forward with clarity and confidence.

Why Insurance Should Be Top of Mind When Hiring a GC in NYC
Every construction project involves risk. In New York City, those risks are amplified by dense job sites, complex permitting, and strict oversight from the Department of Buildings.
Even a small issue with a contractor’s insurance can cause project delays, added costs, or legal exposure. Understanding the basics helps you avoid those surprises and keep your project moving forward.
NYC’s High Risk Construction Environment
Building in New York City comes with a unique set of challenges. Tight job sites, shared building infrastructure, and strict code enforcement all increase the chance that something unexpected could impact your project.
At the same time, city agencies closely monitor construction activity. Missing paperwork or incorrect insurance documentation can delay permits or trigger job site shutdowns. These risks make it especially important to work with a contractor who understands how to stay compliant at every stage.
Insurance Isn’t Just a Legal Requirement—It’s a Client Safeguard
Insurance is often treated as a box to check during pre-construction, but it plays a much bigger role. It’s there to protect everyone involved, including you as the client.
If something goes wrong on-site, whether it’s property damage, an injury, or a delivery accident, insurance coverage helps ensure the issue is handled without disrupting the entire project. It’s not just about legal compliance. It’s about keeping your timeline, budget, and team protected from avoidable setbacks.
This is why a detailed scope of work matters so much: it turns big ideas into clear tasks, realistic budgets, and fewer surprises during execution. A solid proposal should include a clear list of inclusions and a separate list of exclusions so there’s no confusion about responsibilities later. The more detail, the smoother your build.
What Is a Certificate of Insurance (COI)?
A Certificate of Insurance, or COI, is a document that shows proof of a contractor’s insurance coverage. It includes key details like the type of coverage, the policy limits, and when the coverage is active. While it isn’t the full policy, it gives you a clear summary of what’s in place before work begins.
What a COI Includes
A standard COI outlines the types of insurance a contractor carries, the amount of coverage, and the policy dates. It will also list the name of the insured party, the insurance provider, and any certificate holders.
Clients should pay close attention to the policy expiration date and make sure it covers the full duration of the project. It’s also important to confirm that the certificate includes your company or property as a listed holder, so you’re officially recognized in the coverage.
Why Clients Should Request and Review COIs Before Work Starts
Reviewing a contractor’s COI before any work begins helps protect your project from unnecessary risk. It confirms that the contractor’s coverage is active, appropriate for the scope of work, and in line with any building or lender requirements.
It also shows that the contractor is organized and operating professionally. A contractor who can provide a current COI quickly is more likely to handle the rest of the project with the same level of care.
Common Red Flags to Watch For
When reviewing a COI, a few details are worth a closer look. Expired policies, missing coverage types, or unusually low policy limits can all be signs of a potential issue. If the certificate holder section is blank or generic, that’s another reason to ask follow-up questions.
It’s also worth checking that the insurance provider is reputable and that the document appears complete. A professional contractor should have no problem providing a clear, current certificate that meets your project’s needs.
Key Insurance Policies Clients Should Understand
You don’t need to be an insurance expert to make informed decisions about who you hire. But having a basic understanding of common policies can help you ask the right questions and avoid potential gaps in coverage.
This section covers the types of insurance most often listed on a COI and why they matter in commercial construction projects across New York City.
General Liability Insurance
General liability insurance covers third-party claims for property damage or bodily injury that may occur during construction. It’s one of the most common types of coverage listed on a COI.
For commercial projects, this policy helps protect everyone involved if something on the job site causes damage to an adjacent business, common area, or shared system. It’s a baseline expectation for any contractor working in NYC.
Workers’ Compensation
Workers’ compensation insurance provides coverage for job-related injuries or illnesses experienced by a contractor’s employees. In New York State, it’s a legal requirement for most businesses, including general contractors.
For clients, this coverage matters because it helps ensure that injury claims are handled properly through the contractor’s policy—not through unexpected legal action involving the property owner or developer.
Auto and Equipment Coverage
If a contractor uses company vehicles to transport materials, tools, or equipment to the job site, commercial auto insurance may appear on the COI. This policy covers damage or accidents involving those vehicles while in use for work purposes.
Some projects may also require equipment coverage, especially when large or rented machinery is involved. While not needed for every build, these policies are important to check for when vehicle use or heavy equipment is part of the scope.
Excess Liability Coverage
Excess liability coverage provides additional protection beyond the limits of a contractor’s primary policies. It’s often used to meet higher insurance requirements on larger or more complex projects.
This type of coverage helps ensure that adequate funds are available if a major claim arises. While not always required, it’s something clients may see listed on a COI for projects with elevated risk or stricter building requirements.
Subcontractor Insurance: What to Ask and Why It Matters
Even if your general contractor is properly insured, gaps in subcontractor coverage can still create risk. Most commercial projects involve multiple trades, and each one brings its own set of exposures.
Asking how subcontractor insurance is handled can help you avoid liability issues later. It also gives you insight into how organized and compliance-focused your contractor really is.
Why Subcontractor Coverage Affects the Whole Project
Subcontractors often perform high-risk work, from electrical and plumbing to demolition and structural framing. If one of them isn’t properly insured and something goes wrong, the liability doesn’t disappear—it may shift to the general contractor or even the client.
That’s why it’s important to confirm that insurance requirements extend beyond the main GC. Everyone on site should be covered for the specific work they’re doing.
How to Ask About Subcontractor Oversight
You don’t need to review every subcontractor’s policy yourself, but it’s fair to ask how your general contractor manages this part of the process. A professional contractor should be able to explain their approach to verifying coverage and keeping documentation up to date.
Simple questions like “Do you require COIs from all subcontractors?” or “How do you confirm their coverage is current?” can go a long way in understanding how seriously a team takes compliance.
Documentation You Can Request or Review
As the client, you can ask to see a sample COI or request that your business be listed as a certificate holder. This ensures you’ll receive notice if a policy is canceled or updated during the course of the project.
You can also ask for confirmation that subcontractor COIs are collected and reviewed before work begins. While you don’t need to manage these documents yourself, asking for transparency helps protect your interests.
Questions to Ask When Vetting a General Contractor
Understanding insurance coverage is part of choosing the right contractor. Asking clear, focused questions during the hiring process can help you spot potential issues before they become problems.
The goal isn’t to challenge the contractor, but to confirm that they’re operating with the right protections in place—for their team and for your project.
Can You Provide a Current COI with My Company Listed?
This is a common and reasonable request. Asking to be listed as a certificate holder on the contractor’s COI ensures you’ll receive updates if the policy changes or expires during the project.
It also gives you a simple way to verify that coverage is in place and aligns with any building or lender requirements tied to the job.
What Types of Coverage Do You Typically Carry for This Project Type?
This question helps you understand whether the contractor’s insurance is appropriate for your specific scope of work. Coverage needs can vary between a basic interior fit-out and a full commercial build.
You don’t need detailed policy information—just a general sense that the contractor is familiar with the coverage required for your type of project.
How Do You Handle Subcontractor Documentation?
A contractor’s process for collecting and reviewing subcontractor COIs says a lot about how they manage risk. It also shows whether they’re paying attention to compliance details that could affect your project.
Look for an answer that reflects structure—such as requiring COIs before subs begin work and keeping records updated throughout the job.
What Happens If a Vendor’s Coverage Lapses Mid-Project?
Insurance policies can change during a project, especially on longer timelines. It’s worth asking how your contractor monitors coverage and what steps they take if a vendor’s policy expires or is canceled.
A thoughtful response will show that they have a plan in place to catch and address issues early—before they put the schedule or budget at risk.
Clear Coverage Means a Smoother Project
Contractor insurance may not be the most visible part of a project, but it plays an important role in keeping things on track and reducing risk. When clients understand the basics and ask the right questions, they’re more likely to avoid delays, missing documentation, or unexpected liability.
You don’t need to review every policy in detail. You just need a contractor who treats insurance and compliance with the same level of care they bring to the rest of the build.
