Contractor Insurance in New York

Grandbay Financial Services places contractor insurance for New York businesses from its New York office at 1140 Avenue of the Americas. This page covers New York's contractor licensing framework, NYC DOB permit insurance requirements, the Scaffold Law, the NYSDOL contractor registry, workers compensation obligations, and the county-level requirements that apply in New York City, Nassau, Suffolk, and Westchester.

What New York requires

New York has no statewide contractor license, per the New York Attorney General. Licensing requirements apply at the local level. Home improvement contractors must be licensed in New York City, Nassau, Suffolk, Westchester, Putnam, and Rockland counties, and the City of Buffalo.

In New York City, the NYC Department of Buildings requires general contractor registration for 1-, 2-, and 3-family new building permits, at a fee of $300 for a three-year term. Other work uses a Safety Registration Number or an Insurance Tracking Number. Under NYC DOB licensing and insurance guidelines, registered general contractors and Safety Registration applicants cannot submit an affidavit of exemption for workers compensation. Proof must be on Form C-105.2 or U-26.3, and disability proof on Form DB-120.1.

NYC also requires a Home Improvement Contractor license from the Department of Consumer and Worker Protection for home improvement work over $200 in any NYC residential building. That license requires a $20,000 surety bond or Trust Fund enrollment, a workers compensation certificate naming DCWP or a CE-200 exemption, and renewal every two years.

County requirements vary. Nassau requires general liability of $250,000/$500,000 bodily injury and $100,000 property damage with the county as certificate holder, a $650 fee for two years, and a fingerprint check. Suffolk may require general liability of $500,000 per occurrence combined single limit, and a riggers extension of $500,000 per occurrence with a $2,000,000 aggregate for house lifting; contracts by unlicensed contractors are unenforceable in Suffolk. Westchester requires liability insurance in an amount set by the Director, plus workers compensation and disability certificates, at a fee of $750 for two years as of January 1, 2026.

The NYS Department of Labor Contractor and Subcontractor Registry, effective December 30, 2024 under Labor Law 220-i, requires every contractor and subcontractor bidding or working on public work, or on private projects covered by Labor Law 224-a, to register at a fee of $200 for two years and show workers compensation coverage. Unregistered work carries a civil penalty of up to $1,000 and a stop work order.

Under Workers' Compensation Law Section 57, no state or municipal permit, license, or contract is issued without proof of workers compensation. ACORD forms are not acceptable proof; the required forms are C-105.2, U-26.3, SI-12, or CE-200.

Coverage a New York contractor program needs

A complete New York contractor insurance program typically includes the following lines. Coverage depends on the policy wording and endorsements, and the specific limits required by each permit, contract, or county must be confirmed with the relevant authority.

• Commercial general liability. NYC DOB requires general liability of at least one million dollars each occurrence for licensees and registrants. For permitted work, 1 RCNY 101-08 sets project-specific minimums of $5 million, $10 million, $15 million, or $25 million depending on permit type and adjacent building height, $80 million for tower crane permits, $1 million for sidewalk sheds and scaffolds, and $2 million for raising or moving a building. The City of New York must be named as additional insured on CG 20 12 or CG 20 26, and the policy may not contain a completed operations exclusion, an XCU exclusion, a third party action over exclusion, a residential construction exclusion on residential work, an EIFS exclusion, or a New York City work exclusion. Missing or non-compliant insurance can bring a stop work order.
• Workers compensation, disability benefits, and Paid Family Leave. Required of virtually all New York employers under Workers' Compensation Law Sections 2 and 3. The only exemptions are owner-only businesses with no employees. Operating without workers compensation with five or fewer employees is a misdemeanor with a fine of $1,000 to $5,000; with more than five employees it is a class E felony with a fine of $5,000 to $50,000, plus a civil penalty of up to $2,000 for each 10-day period and a stop work order.
• Umbrella or excess liability. Given the permit minimums under 1 RCNY 101-08 and the Scaffold Law exposure, umbrella limits are typically required on New York construction projects. The appropriate limit depends on the permit type, contract requirements, and the nature of the work.
• Builders risk. Covers the structure under construction against physical loss. Whether builders risk is required depends on the contract and the project owner's requirements. Coverage depends on the policy wording and endorsements.
• Surety bonds. The NYC DCWP Home Improvement Contractor license requires a $20,000 surety bond or Trust Fund enrollment. Public work may require payment bonds under State Finance Law Section 137, which may be waived for contracts under $100,000.

What underwriters ask New York contractor operators

• NYSDOL registry status. Under Labor Law 220-i, effective December 30, 2024, every contractor and subcontractor on public work or covered private projects must be registered. Underwriters ask whether the contractor and its subcontractors are registered and whether workers compensation certificates are current.
• Workers compensation compliance. Under Workers' Compensation Law Section 57, no permit, license, or contract is issued without proof of workers compensation on the required forms. Underwriters ask for current C-105.2 or U-26.3 certificates and review loss runs for frequency and severity of workers compensation claims.
• Subcontractor certificate collection. Under 1 RCNY 101-08, a permit policy may not contain a third party action over exclusion, which is aimed at claims arising from a subcontractor's injured worker; whether a given claim is covered depends on the policy wording and endorsements. Underwriters ask whether the contractor collects certificates of insurance and additional insured endorsements from all subcontractors before work begins.
• Type of work and project mix. Underwriters distinguish between residential and commercial work, new construction and renovation, and the trades involved. The Scaffold Law applies to all construction, excavation, and demolition work, but the frequency and severity of claims varies by trade and project type.
• Loss history. Given the claim frequency described in the Chubb and Aon paper using 2011 to 2019 data, underwriters scrutinize loss runs carefully for New York construction risks. A clean loss history and documented safety program are material underwriting factors.
• Contract review. Under General Obligations Law 5-322.1, a construction contract clause indemnifying a party for its own negligence is void and unenforceable. Underwriters ask whether the contractor's standard subcontract language complies with this rule and whether additional insured endorsements are project-specific or blanket.

New York laws that shape claims and costs

Labor Law 240(1) and 241(6) (the Scaffold Law). Under Labor Law 240(1), all contractors and owners, except owners of one- and two-family dwellings who contract for but do not direct or control the work, must furnish scaffolding, hoists, ladders, and other devices so constructed, placed, and operated as to give proper protection to workers. Labor Law 241(6) requires reasonable and adequate protection in all construction, excavation, and demolition areas. These statutes impose absolute liability on contractors and owners for gravity-related injuries. According to a Chubb and Aon paper using 2011 to 2019 data, bodily injury general liability claims in New York occur at a rate far higher than in other states, and claims over $250,000 are far more frequent, which is reflected directly in New York construction insurance premiums.

Workers' Compensation Law Section 11 (third party action over). Under Workers' Compensation Law Section 11, an owner or general contractor can seek contribution or indemnity from the injured worker's employer only if the worker suffered a grave injury as defined in the statute, or if the employer agreed to indemnify in a written contract entered into prior to the accident. This rule shapes how additional insured and indemnification clauses are drafted in New York construction contracts, and it is the exposure that the 1 RCNY 101-08 prohibition on action over exclusions addresses.

General Obligations Law 5-322.1. A construction contract clause indemnifying a party for its own negligence, whether in whole or in part, is against public policy and is void and unenforceable under General Obligations Law 5-322.1. Insurance contracts are not affected. This rule limits the extent to which a general contractor can shift its own Scaffold Law exposure to a subcontractor through contract language alone.

Labor Law 224-a (prevailing wage on private projects). Under Labor Law 224-a, prevailing wage requirements extend to private projects over $5 million with at least 30 percent public funding. The NYSDOL contractor registry requirement under Labor Law 220-i applies to these projects as well.

What changed in 2024 to 2026

• NYSDOL Contractor and Subcontractor Registry (December 30, 2024). Under Labor Law 220-i, every contractor and subcontractor bidding or working on public work, or on private projects covered by Labor Law 224-a, must register with the NYSDOL at a fee of $200 for two years and show workers compensation coverage. Unregistered work carries a civil penalty of up to $1,000 and a stop work order. This requirement took effect December 30, 2024 and applies to new bids and contracts from that date.
• Westchester fee increase (January 1, 2026). The Westchester County home improvement contractor license fee increased to $750 for two years, effective January 1, 2026, per the February 2026 application form.
• Labor Law liberal construction bill (June 2026). A bill directing courts to construe the Labor Law liberally passed both houses in June 2026. Its signature status is not confirmed. If enacted, it would affect how courts interpret Labor Law 240 and 241 claims.
