TL;DR: New York Labor Law Section 240 (the Scaffold Law) imposes absolute liability on GCs for gravity-related injuries, even when the worker was at fault, making robust subcontractor insurance the only thing standing between the GC and seven-figure judgments. Require $1M/$2M GL minimum (often $2M/$5M for elevated work), CG 20 10 + CG 20 37 endorsements, and a current NY workers' comp certificate from every sub.

If you're a general contractor working in New York, you already know the state plays by its own rules. Between New York's infamous Scaffold Law, some of the strictest workers' compensation enforcement in the country, and a patchwork of local licensing requirements, compliance here demands more attention than almost anywhere else in the US.

This guide breaks down exactly what you need from your subcontractors before they set foot on a New York jobsite, and what happens if you skip any of it.

Why New York Is Different (The Scaffold Law Warning)

Before anything else, you need to understand Labor Law § 240, commonly called the "Scaffold Law." It's been on the books since 1885 and it imposes absolute liability on property owners and general contractors for gravity-related injuries. Falls, falling objects, scaffolding collapses. Regardless of how the accident happened or whether the injured worker was at fault.

That means if a subcontractor's employee falls from a ladder on your jobsite because they ignored safety instructions, you can still be held 100% liable. New York is the only state in the US that still has this absolute liability standard. Every other state either repealed similar laws or modified them to allow comparative fault.

The practical impact: your subcontractors' insurance coverage directly protects you. Thin coverage, expired certificates, or missing endorsements can leave you personally exposed to seven-figure judgments. This is not a paperwork formality in New York. It's serious financial risk management.

New York Contractor Licensing

New York does not have a single statewide general contractor license. Instead, licensing is handled at the local level, and requirements vary dramatically depending on where you work.

New York City

NYC has the most complex licensing system in the state. The Department of Buildings (DOB) administers several license types:

General Contractor Registration: required to file construction permits in NYC
Home Improvement Contractor (HIC) License: required for residential work in the five boroughs (issued by the NYC Department of Consumer and Worker Protection)
Specialty licenses: electricians, plumbers, and other trades have separate DOB licenses

For NYC subcontractors, always verify their registrations at nyc.gov/buildings before they start work.

Other Jurisdictions

Westchester, Nassau, Suffolk Counties all have their own contractor licensing systems
City of Buffalo, Rochester, Yonkers require local registrations
Most towns and villages require building permits tied to licensed contractors

Bottom line: Before hiring any sub for a New York project, confirm what the local licensing requirements are for that specific jurisdiction. Don't assume a license from one county or city is valid in another.

General Liability Insurance Requirements

Most New York public and private projects require subcontractors to carry general liability insurance with these minimum limits:

Coverage	Typical Minimum
Per Occurrence	$1,000,000
General Aggregate	$2,000,000
Products/Completed Operations	$2,000,000
Personal & Advertising Injury	$1,000,000

Higher limits are common. Many NYC commercial projects, public projects, and large private owners require $2M/$4M or even $5M/$5M. Always check your prime contract. Those limits flow down to your subs.

The Additional Insured Endorsement Is Non-Negotiable

Because of the Scaffold Law, getting named as an additional insured on your subcontractor's GL policy isn't just good practice. It is required. You need:

Additional Insured Endorsement (CG 20 10 and CG 20 37): both the ongoing operations and completed operations versions
Primary and Non-Contributory language: so the sub's policy pays first before your policy is touched
Waiver of Subrogation: prevents the sub's insurer from suing you after paying a claim

Get the actual endorsement pages, not just a certificate that says these exist. Certificates are summaries. They're not legally binding proof of coverage terms.

Workers' Compensation Requirements

New York has mandatory WC coverage for virtually every employer. The rules are strict, enforcement is active, and the penalties for non-compliance are severe.

Who Must Be Covered

Under New York Workers' Compensation Law, every employer with one or more employees must carry workers' compensation insurance, including day laborers, casual workers, and part-time workers. There is no minimum hours threshold or payroll minimum like some states.

This applies to:

All subcontractors you hire
Any sub-subcontractors they use
Workers classified as "independent contractors" (more on this below)

The Misclassification Problem

New York aggressively pursues worker misclassification. The Workers' Compensation Board and the Department of Labor both investigate whether someone labeled an "independent contractor" should legally be an employee. If a sub's workers get reclassified, the sub may be found to have had uninsured employees, and you as the GC can face liability for their injuries.

Protect yourself: Require every subcontractor to provide a valid WC certificate. Don't accept anyone working as a "sole proprietor 1099" without verifying their exempt status.

Workers' Comp Exemptions in New York

New York allows very limited WC exemptions:

Sole proprietors: can exempt themselves from their own WC policy (but are not automatically exempt; they must specifically exclude themselves)
Partners in a partnership: can exclude themselves
Corporate officers: can file Form C-105.32 to elect not to be covered, but only if they own at least 10% of the company's stock: this is the most commonly used exemption for small subcontracting businesses.

Important: Even if a corporate officer is WC-exempt, that exemption only covers that individual. If they have any other employees, full WC coverage is still required.

To verify a WC exemption, request the WC-Exempt Certificate and cross-check it against the New York Workers' Compensation Board's online system at wclawboard.ny.gov.

Coverage Sources

New York subcontractors can obtain WC coverage through:

Private carriers
The New York State Insurance Fund (NYSIF): a state-run insurer that is the largest WC carrier in New York; many smaller subs use NYSIF

When you verify a COI, make sure the policy number on it is active. The NYSIF has a verification portal you can use to confirm current policy status.

Penalties for Non-Compliance

Operating without WC in New York is a misdemeanor. Civil penalties can reach $2,000 per 10-day period of non-compliance. Criminal penalties include fines up to $50,000 and potential jail time for officers of corporations. The Workers' Compensation Board has the authority to issue stop-work orders and can assess penalties against GCs who knowingly use uninsured subs.

Disability Benefits Insurance

New York is one of only a handful of states that also requires employers to carry statutory disability benefits insurance (covering off-the-job injuries and illnesses). This is separate from workers' comp. All employers with one or more employees must provide DB coverage.

Subcontractors should have a separate DB certificate or show that their WC carrier also provides DB coverage. This often gets overlooked. Don't let it fall through the cracks.

W-9 and 1099 Requirements

W-9 and 1099 requirements in New York follow federal IRS rules, with no additional state-specific forms required.

The basics:

Collect a completed W-9 from every subcontractor before making any payments
Issue a 1099-NEC by January 31st for any sub paid $600 or more during the calendar year (if they're not a corporation)
Also file with the IRS by January 31st

The penalty: The IRS can assess $310 per missing or incorrect 1099 (for 2026), with higher penalties for intentional disregard. If you're paying dozens of subs, missing forms add up quickly.

New York also has state income tax withholding rules. If a subcontractor is a non-resident performing services in New York, there may be state-level withholding requirements. Particularly relevant for subs who live in New Jersey or Connecticut and work on New York projects. Consult your accountant if this applies.

Practical step: Make it a policy that no first check gets cut until the signed W-9 is in hand. If you use PaperBoss, you can automate this. Subs get a reminder and you don't have to chase anyone manually.

Lien Waiver Requirements in New York

New York's mechanics lien law is governed by Article 2 of the New York Lien Law, and it has some notable quirks compared to other states.

No Mandated Lien Waiver Forms

Unlike many states, New York does not have mandatory statutory lien waiver forms. You can use your own forms, but there are important rules to follow:

Lien waivers are not valid consideration if signed before payment is actually received. A lien waiver signed with a draw request but before the check clears has questionable enforceability
Lien waivers must be specific enough to identify what work/invoices are being waived
Partial (conditional) waivers are common and legally effective

The Notice Requirement

New York requires that certain contractors file a Notice of Lien within:

4 months from the last date work was performed or materials were provided (for private projects)
1 year for public improvement projects

A sub who hasn't been paid can file a lien against your project. Collecting lien waivers as you pay your subs is the way you document that they've been paid and have no lien rights remaining for that period of work.

Trust Fund Provisions

This is unique to New York: Under Article 3-A of the Lien Law, construction payments are held in trust for the benefit of the people who performed the work and provided materials. Misappropriating trust funds. Using a draw payment for something other than paying subs and suppliers. Is a crime in New York. Keep project funds separate and pay subs from project funds promptly.

New York-Specific Compliance Checklist

Before allowing any subcontractor to mobilize on a New York project, confirm you have:

Licensing

Valid local contractor license or registration for the specific jurisdiction
Any required trade licenses (electrician, plumber, etc.)

Insurance

Current Certificate of Insurance (COI) showing GL, WC, and DB coverage
GL limits meet or exceed contract requirements
You are named as Additional Insured (ongoing + completed operations)
Primary and Non-Contributory language confirmed
Waiver of Subrogation confirmed
Actual endorsement pages obtained (not just the certificate)
WC policy confirmed active (especially for NYSIF policies)

Exemptions

If claiming WC exemption: valid Form C-105.32 on file, verified with WCB
Disability Benefits exemption verified if applicable

Tax Documents

Signed W-9 on file before first payment
1099-NEC tracking set up for end-of-year

Lien Management

Lien waiver collected with each payment
Conditional waivers used when paying by check (before check clears)
Unconditional waivers collected after payment confirms

Ongoing

COI expiration tracked. Alert set for 30 days before expiration
Sub-subcontractor COIs obtained (your subs' subs also need to be covered)

The Biggest Mistakes New York GCs Make

1. Accepting a COI without checking endorsements. The certificate is a summary document only. It doesn't prove that the additional insured endorsement actually names you. Get the endorsement pages.

2. Not tracking sub-subcontractors. Your subcontractor hires someone below them. That person gets hurt. The Scaffold Law still exposes you. Your sub contract should require subs to flow your insurance requirements down to anyone they hire.

3. Letting COIs expire mid-project. A two-week gap in coverage during a six-month project is enough to leave you exposed. Track expiration dates proactively, not reactively.

4. Missing the disability benefits requirement. Many GCs focus on GL and WC and forget that New York requires DB coverage. It's a separate requirement and a separate certificate.

5. Using vague lien waivers. A lien waiver that says "waives all claims" without specifying the project, the amount, or the invoice period can be challenged. Use specific, project-dated language.

Managing Compliance at Scale

If you're managing five or fewer subs on a single project, a spreadsheet might work. Once you're running multiple projects with 10, 20, or 30 subcontractors. Each with different insurance renewal dates, exemption certificates, W-9s, and lien waivers. Manual tracking becomes a liability itself.

PaperBoss was built specifically for this. It tracks COI expiration dates for every sub, sends automatic reminders when documents are coming due, and stores everything in one place so you're not hunting through email when a WC auditor calls. The free trial takes about 10 minutes to set up.

Bottom Line

New York's Scaffold Law makes subcontractor insurance compliance more important here than almost anywhere else in the country. One uninsured sub, one missing endorsement, one expired certificate. Any of these can turn a routine jobsite accident into a lawsuit that puts your business at risk.

The paperwork is tedious. The requirements are layered, but every document you collect is a layer of protection between you and an absolute liability claim.

Get your systems in order before you need them.
