New York Plumber License Insurance and Bond Requirements

No Insurance, No Permits

Every New York municipality that licenses plumbers requires proof of insurance before issuing building permits or activating a master plumber license. This isn't optional or negotiable — your license is effectively dormant without current certificates on file. And unlike some states where you submit proof once and forget about it, New York boards typically require updated certificates at every renewal.

The specific coverage requirements vary by jurisdiction, but three categories are universal across the state: general liability, workers' compensation, and disability benefits.

General Liability Insurance

General liability covers third-party property damage and bodily injury claims arising from your plumbing work. The minimum coverage varies by jurisdiction:

• New York City: $1,000,000 per occurrence. This is the standard across all five boroughs and is verified during the master plumber application and at each triennial renewal.
• Suffolk County: $500,000 per occurrence minimum for the county-level master plumber license.
• Nassau County towns: Varies by town — typically $500,000 to $1,000,000 per occurrence depending on the specific town or village.
• Buffalo and Rochester: City-specific liability minimums, generally in the $1,000,000 range.

Each insurance certificate must name the specific licensing authority as the certificate holder. A policy listing "NYC Department of Buildings" won't satisfy Suffolk County's requirements. If you hold licenses in multiple jurisdictions, you'll need separate certificates — or a single policy with multiple certificate holders listed — for each one.

Workers' Compensation Insurance

New York State law requires workers' compensation coverage for all employees. This applies to every plumbing business with W-2 employees, regardless of which municipality issued the license.

Acceptable proof must be provided on specific state forms:

• Form C-105.2 for coverage from private insurance carriers
• Form U-26.3 for coverage from the New York State Insurance Fund (NYSIF)

These are the only formats accepted by municipal building departments. A generic ACORD certificate won't satisfy the requirement for workers' comp verification — the board needs to see the state-specific form.

Disability Benefits Law (DBL) Insurance

New York also mandates disability benefits coverage for employees, verified on Form DB-120.1. This provides short-term disability payments to employees who become unable to work due to off-the-job injury or illness. Like workers' comp, it's a state requirement enforced at the municipal licensing level.

The CE-200 Exemption for Sole Proprietors

If you're a sole proprietor or single-member LLC with zero W-2 employees, you don't need workers' compensation or disability insurance. Instead, you file a CE-200 certificate of exemption with the New York State Workers' Compensation Board.

The CE-200 is free to obtain through the Workers' Compensation Board's online portal. It serves as proof that you're exempt from the coverage requirement because you have no employees. Most municipal licensing boards accept the CE-200 in place of workers' comp and disability certificates.

One important caveat: the moment you hire your first employee — even a part-time helper — the CE-200 exemption is invalidated. You must immediately obtain workers' comp and DBL coverage, and update your certificates with every licensing board you're registered with.

NYC DOT Plumber Surety Bond

This is a requirement unique to New York City. To obtain street-opening and utility permits from the NYC Department of Transportation, master plumbers must secure a dedicated $3,000 Plumber Surety Bond. This bond guarantees that you'll restore any public roadway or sidewalk you excavate to its original condition.

The bond is separate from your general liability insurance and must be filed with the DOT directly. It's required only for work that involves opening a public street or connecting to a municipal utility — typical residential interior plumbing jobs don't trigger it. But if your business does any sewer line connections, water main tie-ins, or gas service installations that involve breaking pavement, you'll need this bond on file.

Surety bond premiums vary with your credit and business history. Ask a surety provider for the current premium for a $3,000 bond.

Structuring Your Insurance for Multiple Jurisdictions

If you work across multiple New York jurisdictions — a common scenario for Long Island plumbers covering both Nassau and Suffolk, or Westchester plumbers who also work in NYC — your insurance logistics multiply quickly.

Each jurisdiction requires its own certificate holder designation. Many plumbers work with an insurance broker who specializes in construction trades to manage this. The broker can issue multiple certificates from the same underlying policy, each naming a different municipality as the certificate holder.

The New York Plumber License Guide includes an insurance and bond workbook that maps every major jurisdiction's coverage minimums, certificate holder requirements, and the specific state forms you'll need — so you can set up your policies correctly before you start the licensing application process.
