NYC construction insurance guide: required coverages for contractors and developers, builder's risk, wrap-up insurance, additional insured requirements, and a COI checklist for NYC projects.
Construction Insurance Requirements
What insurance coverages are required for construction in NYC?
NYC construction projects typically require: (1) Commercial General Liability (CGL) — bodily injury and property damage coverage; minimum $1M per occurrence, $2M aggregate for most projects; (2) Workers' Compensation — mandatory for all employees; (3) Employer's Liability — $1M per occurrence; (4) Commercial Auto — for any vehicles used at the jobsite; (5) Umbrella/Excess Liability — $5M-$25M depending on project size; (6) Builder's Risk — for the structure under construction. DOB and most property owners require proof of all these before work begins.
What is Builder's Risk insurance and who buys it?
Builder's Risk (also called Course of Construction) insurance covers the structure being built or renovated against loss from fire, wind, theft, vandalism, and other perils during the construction period. It is typically purchased by the property owner (or developer) and covers the full replacement value of the completed project at the end. Subcontractors and their equipment are typically not covered under the owner's builder's risk — they need their own installation floater or inland marine coverage.
What minimum CGL limits should NYC contractors carry?
Minimum limits vary by project type and contract requirements: (1) Small residential projects (under $500K): $1M/$2M minimum; (2) Mid-size commercial or residential ($500K-$5M): $2M/$4M, plus $5M umbrella; (3) Large projects (over $5M): $5M/$10M minimum plus $10-25M umbrella. DOB project requirements and private owner contracts often specify minimum limits. Never carry less than contract-required limits — you risk both contract breach and being unprotected in a serious loss.
What is an Additional Insured endorsement and when is it required?
Additional insured endorsements extend coverage under a contractor's policy to a third party (typically the property owner, general contractor, or lender). The additional insured is protected for claims arising from the named insured's operations. NYC construction contracts almost universally require contractors to name the property owner and general contractor as additional insureds. The endorsement should be "blanket additional insured" and cover ongoing operations and completed operations.
What is "completed operations" coverage?
Completed operations coverage extends GL insurance to cover claims that arise after the work is completed and the job is done — for example, if a building collapses six months after construction or a water leak is discovered after the plumber left. Many standard CGL policies cover completed operations only for a limited period. NYC contracts often require completed operations coverage to remain in place for 5-10 years after completion. Confirm completed operations is included and for how long.
What is an Installation Floater and do contractors need it?
An Installation Floater (or Contractor's Equipment floater) covers equipment, tools, and materials the contractor brings to the jobsite — until they are permanently installed. Once materials are installed and become part of the building, they may fall under the builder's risk policy. Contractors who bring significant equipment or materials to sites should carry this coverage. Without it, stolen tools or damaged materials that aren't yet installed may not be covered.
What is professional liability (E&O) insurance and do NYC contractors need it?
Professional Liability (also called Errors and Omissions or E&O) covers claims arising from design errors, faulty plans, incorrect specifications, or negligent professional services. Design-build contractors, contractors who provide design advice or stamp plans, and specialty contractors (structural engineers, MEP engineers) should carry professional liability. General contractors who don't provide design services typically don't need it, but it's increasingly required on sophisticated projects.
What is a COI and what should I check before accepting one from a subcontractor?
A Certificate of Insurance (COI) is a summary document from the insurer. Before accepting: (1) Check coverage types match your requirements; (2) Verify limits are sufficient; (3) Confirm effective and expiration dates — COIs with coverage dates in the past are worthless; (4) Ensure your entity is named as additional insured, not just listed on the certificate; (5) Verify the insurer is admitted in New York and A-rated; (6) Check that WC is listed — absent WC means the sub's workers may be uninsured; (7) Request the actual endorsement confirming additional insured status for important coverages.
What is Pollution Liability and when is it required for NYC construction?
Pollution Liability covers bodily injury and property damage arising from pollution conditions — including asbestos, lead paint, mold, fuel oil spills, and other environmental contaminants. For NYC construction work involving demolition, renovations in older buildings, or excavation near contaminated sites, pollution liability is frequently required. Standard CGL policies typically exclude pollution claims. Environmental contractors (asbestos abatement, lead paint removal, soil remediation) must carry specialized pollution policies.
