Do You Need a License to Be a General Contractor in New York?

Andrew Booth Andrew Booth

For most construction work, New York does not issue a statewide general contractor license. Licensing is handled by individual cities and counties. Whether you need one depends entirely on where you’re working and what kind of jobs you’re taking.

Key takeaways

  • New York has no statewide general contractor license for most work
  • NYC requires both a DOB registration and, for residential work, a separate Home Improvement Contractor license
  • Nassau, Suffolk, Westchester, Putnam, Rockland, and Buffalo all require their own licenses
  • No jurisdiction recognizes another’s license — each is a separate application
  • Public works contractors must register with the NY State Department of Labor regardless of county
  • License numbers must appear on contracts, invoices, and advertisements in most jurisdictions that require them

At the state level: almost nothing

New York State licenses two categories of contractors directly: asbestos handling contractors and crane operators, both through the New York State Department of Labor. Everyone else gets licensed (or doesn’t) at the city or county level.

New York City: two agencies, two requirements

NYC is the most layered. General contractors have to deal with two separate agencies depending on what they’re building.

DOB registration. Under NYC Administrative Code §28-418, all general contractors must register with the NYC Department of Buildings to pull permits and supervise construction or demolition work. You also need a physical place of business in New York City. Once registered, your license number and business information must appear on trucks, business cards, and advertisements.

Home Improvement Contractor license. If you’re working on a 1-, 2-, 3-, or 4-family home or an individual condo or co-op unit, DOB registration isn’t enough. You also need a Home Improvement Contractor (HIC) license from the NYC Department of Consumer and Worker Protection (DCWP). The threshold is residential home improvement work costing more than $200.

Two requirements. Two agencies. Both apply if you’re doing residential work in the city. Contractors who register with the DOB and skip the DCWP license are still unlicensed for residential work.

The jurisdictions that require a license

Nassau County

Nassau County requires a Home Improvement Contractor license administered by the Nassau County Department of Consumer Affairs. The license covers residential home improvement work. Electrical and plumbing contractors who hold a separate state or local “standard of competency” license are exempt from the general HIC requirement. electricians, for example, are licensed at the town level in Nassau but GCs are not.

Suffolk County

Suffolk County licenses home improvement contractors through the Department of Labor, Licensing and Consumer Affairs. A written exam is required. Application fee is $200; the annual license fee is $200. The license runs on a temporary basis initially, then converts to a regular license valid through the last day of the 24th month following issuance.

Required at application and renewal: certificates of public liability and property damage insurance, plus workers’ compensation coverage.

Advertising requirement: under Suffolk County Code §563, all advertising for home improvement contracting must include your license number. That includes estimates, invoices, and any promotional materials.

Escrow rule: any contract payments received before substantial completion must be deposited into a New York State bank trust account within five business days. The customer must be notified of the account location within ten business days.

Westchester County

Westchester County licenses home improvement contractors through the Westchester County Department of Consumer Protection. The license number must appear on all advertisements, contracts, invoices, proposals, and stationery.

Putnam and Rockland Counties

Both require their own home improvement contractor licenses. Contact each county’s consumer affairs office directly for current requirements.

City of Buffalo

Buffalo requires its own contractor license. Contact the City of Buffalo Permit and Inspection Services for current requirements.

Do jurisdictions recognize each other’s licenses?

No. Each runs its own licensing program independently. A Nassau County license doesn’t authorize work in Suffolk County, Westchester, or New York City. If you’re working across multiple jurisdictions, you need a separate license for each one that requires it. Same application process, same fees, no shortcuts.

The rest of New York State

Working in Rochester, Albany, Syracuse, Yonkers, or most other parts of New York State outside the jurisdictions listed above? Most jurisdictions outside those listed do not require a county-level home improvement contractor license, though local registration, permit, or municipal requirements may still apply. Before starting work in any municipality, check with the local building department to confirm what’s required in that specific location.

The statewide public works registry

This is a separate track entirely, and it applies regardless of county.

As of December 30, 2024, New York Labor Law Section 220-i requires all contractors and subcontractors to register with the New York State Department of Labor before bidding on or starting work on public work projects, or certain private projects covered under Article 8 of the Labor Law. Article 8 covers publicly subsidized projects, renewable energy, broadband, and certain roadway work.

Registration is $200 ($100 for state-certified MWBEs per the NYSDOL FAQ), produces a Certificate of Registration with a unique number valid for two years, and is done through the NYSDOL Contractor Registry portal. If you’re the GC, you’re responsible for confirming your subs are registered before they start.

Remodeling a kitchen for a homeowner in Westchester: this doesn’t apply. Renovating a school or a publicly subsidized building: it does.

License numbers on paperwork

If you’re licensed in a jurisdiction that requires one, the display rules matter.

NYC requires your registration number on trucks, business cards, and advertisements under Administrative Code §28-418. Westchester requires it on every invoice, proposal, contract, and ad. Suffolk requires it in all advertising. Other jurisdictions have their own versions of the same requirement.

If your job management software doesn’t carry that number through automatically to every estimate and invoice you send, you’re either manually adding it or risking documents going out without it. Cinderblock handles that automatically, so your license number shows up on every document without you thinking about it.

Frequently Asked Questions

No. New York State does not issue a statewide general contractor license for most construction work. Licensing is handled at the city or county level. The only contractors licensed at the state level are asbestos handling contractors and crane operators, both through the New York State Department of Labor.
Yes. General contractors in New York City must register with the NYC Department of Buildings under NYC Administrative Code §28-418. If the work involves a 1-, 2-, 3-, or 4-family home or individual condo or co-op unit, you also need a separate Home Improvement Contractor license from the NYC Department of Consumer and Worker Protection (DCWP). DOB registration alone is not sufficient for residential work.
Home improvement contractors must be licensed in New York City, Nassau County, Suffolk County, Westchester County, Putnam County, Rockland County, and the City of Buffalo. Outside these jurisdictions, most areas do not require a county-level home improvement license, though local permit and registration rules may still apply.
There is no single New York contractor license fee because licensing is handled locally. Suffolk County charges a $200 application fee plus $200 annually. NYC, Nassau, Westchester, Putnam, and Rockland each set their own fees — verify current amounts directly with each agency’s consumer affairs or licensing office before applying, as fees change.
It depends on the jurisdiction and trade. In NYC, subcontractors performing work that requires a permit generally need their own registration or license. In Nassau, Suffolk, and other jurisdictions with home improvement licensing, subcontractors who directly contract with homeowners typically need their own license. Subcontractors working under a licensed GC on public work projects must also register with the NY State Department of Labor under Labor Law Section 220-i. Check requirements with the relevant local authority for the specific trade and jurisdiction.
No. Each jurisdiction runs its own licensing program. A home improvement contractor license issued by Nassau County does not authorize work in Suffolk County, Westchester County, or New York City. If you work across multiple jurisdictions, you need a separate license for each one that requires it.
No. NYC DOB registration and DCWP Home Improvement Contractor licenses apply only within New York City. Other counties and municipalities have their own licensing and registration requirements. Working in Nassau, Suffolk, or Westchester requires a separate license from each jurisdiction.
