How to Check a Contractor's License in New York

New York does not have a statewide general contractor license. If you're coming from a state like California or Florida where there's a single database to search, New York will feel disorganized. That's because it is. Licensing is handled at the city and county level, and the rules change depending on where you live and what kind of work you need done.

This guide walks you through how to verify a contractor in New York, covering NYC, the surrounding counties, and specialty trades. It's more complicated than other states, but knowing where to look makes all the difference.

Why doesn't New York have a statewide contractor license?

New York chose to delegate contractor licensing to cities and counties rather than the state, which means there is no central database and no single agency in charge. This is unusual compared to most states. The first thing you need to determine is where the work is being done, because that tells you which local agency to check with.

Most states have a centralized licensing board that handles all contractor licenses. New York does not. There is no state-level general contractor license, no statewide database, and no single agency in charge.

Instead, licensing requirements are set by individual cities and counties. New York City has the most comprehensive system, but Westchester, Nassau, Suffolk, and other counties each have their own rules. Some smaller municipalities have no licensing requirements at all for general contractors.

This means the first thing you need to figure out is where the work is being done, because that determines which agency you need to check with.

What license does a contractor need to work in New York City?

In New York City, any contractor doing residential home improvement work must hold a Home Improvement Contractor (HIC) license from the NYC Department of Consumer and Worker Protection (DCWP). This is a hard legal requirement — working without one is illegal. The license covers most residential renovation work across all five boroughs.

In NYC, any contractor performing home improvement work must hold a Home Improvement Contractor (HIC) license issued by the NYC Department of Consumer and Worker Protection (DCWP), formerly known as the Department of Consumer Affairs (DCA). This applies to general contractors, remodelers, renovators, handymen charging over a certain threshold, and most other residential contractors.

The HIC license requirement covers a wide range of work:

• Kitchen and bathroom renovations
• Roofing, siding, and window installation
• Painting and flooring
• General remodeling and additions
• Basement finishing
• Fencing, decking, and exterior work

If someone is doing residential work in any of the five boroughs and they don't have an HIC license, they are operating illegally.

How do you look up an NYC contractor license online?

Go to the NYC DCWP License Verification page, select "Home Improvement Contractor" from the Industry dropdown, and search by business name or license number. The results show license status, expiration date, and business address. If the contractor doesn't appear, ask them directly for their HIC number.

The DCWP maintains an online license verification tool. Here's how to use it:

1. Go to the NYC DCWP License Verification page.
2. Under "Industry," select "Home Improvement Contractor" from the dropdown.
3. Enter the contractor's business name or license number. If you have the license number, use that. It's faster and more reliable.
4. Click "Search."

The results will show:

• Business name - the name registered with the city
• License number - their unique HIC number
• License status - active, expired, or inactive
• Expiration date- make sure it hasn't lapsed
• Business address- where they're registered

A few tips for searching: try the business name with and without "LLC" or "Inc." If the contractor does business under a different name than the legal entity, you might need to try both the DBA name and the legal name. If the search returns nothing, ask the contractor for their HIC license number directly.

How do you check if an NYC contractor has complaints against them?

After confirming a valid license, check the DCWP's complaint history through the same verification tool or by calling 311. The NYC Department of Buildings also tracks violations and stop-work orders from past projects, which can reveal patterns of substandard work that a clean license record alone won't show.

Finding a valid license is step one. Step two is checking whether anyone has filed complaints against the contractor. The DCWP tracks consumer complaints, and you can check this through the same verification tool or by calling 311 (NYC's information line).

You can also check the Better Business Bureau and the NYC Department of Buildings (DOB) for any violations or stop-work orders associated with the contractor's past projects.

How do you verify an electrician or plumber's license in NYC?

Electricians and plumbers in New York City are licensed through the NYC Department of Buildings (DOB), not the DCWP. Search the DOB's Building Information System by name or license number to confirm the license type and status. A general contractor's HIC license does not cover electrical or plumbing work — those require separate DOB credentials.

General contractors need an HIC license from DCWP, but specialty trade workers are licensed through a different agency entirely. In New York City, electricians and plumbers are licensed by the NYC Department of Buildings (DOB).

To verify an electrician or plumber's license:

1. Go to the NYC DOB Building Information Search (BIS).
2. Use the "Licensed Professional" search to look up the individual by name or license number.
3. Verify that the license is current and matches the type of work you need. There are different license categories for master plumber, licensed master electrician, special electrician, and others.

This is important: a general contractor with an HIC license cannotdo electrical or plumbing work themselves unless they also hold the appropriate DOB license. They should be subcontracting that work to a licensed specialist. If your contractor says they'll handle the plumbing or electrical work personally, ask for that specific license.

How do you check a contractor's license outside New York City?

In the New York suburbs and upstate cities, licensing varies by county. Westchester, Nassau, and Suffolk counties each have their own home improvement contractor registries through their consumer protection offices. Many rural areas and smaller municipalities have no general contractor licensing requirement at all, though building permits are still required for most work.

If you're outside the five boroughs, the licensing landscape gets patchier. Here are the major counties with their own requirements:

• Westchester County - requires home improvement contractor registration through the Westchester County Department of Consumer Protection. You can verify a contractor on the Westchester County Consumer Protection website. Contractors must carry insurance and a surety bond.
• Nassau County - requires home improvement contractor licensing through the Nassau County Office of Consumer Affairs. You can call their office or check online for license verification. Contractors must also carry general liability insurance.
• Suffolk County - requires home improvement contractor licensing through the Suffolk County Department of Consumer Affairs. They maintain a searchable database of licensed contractors. Suffolk County also requires contractors to carry a surety bond.
• Rockland County- has its own home improvement licensing requirements through the county's consumer protection office.

For upstate New York and other areas, requirements vary widely. Some cities like Buffalo, Rochester, and Syracuse have their own licensing requirements, often handled through the city clerk or local building department. Many rural areas and smaller towns have no general contractor licensing requirement at all, though building permits are still required for most significant work.

What else should you verify beyond the contractor's license?

A valid license is necessary but not sufficient. You should also confirm general liability insurance (at least $1 million for significant projects), workers' compensation coverage through the NY Workers' Compensation Board, surety bond status, and active business registration with the New York Department of State. Skipping any of these checks leaves you exposed.

• General liability insurance.Ask for a certificate of insurance (COI) and call the insurance company to confirm it's current. In NYC, HIC-licensed contractors are required to carry at least $100,000 in liability insurance, but you should look for contractors carrying $1 million or more for significant projects.
• Workers' compensation insurance.If the contractor has any employees (and most do), they must carry workers' comp in New York State. Without it, you as the homeowner could be liable for injuries that happen on your property. You can verify workers' comp coverage through the New York Workers' Compensation Board.
• Surety bond. NYC HIC-licensed contractors must carry a surety bond. This provides a small layer of financial protection if the contractor fails to complete the work or violates the contract terms.
• Business registration. Check that the contractor is registered as a legitimate business with the New York Department of State. You can search the NY Department of State Corporation and Business Entity Database to verify their business is in good standing.

What should you do if you can't find a contractor in any New York database?

Ask the contractor for their license number directly — a legitimate contractor provides it without hesitation. If they still don't appear after searching by name and number, verify whether licensing is even required in your specific location. In New York City, an unlicensed contractor is a dealbreaker: it is illegal to do home improvement work in the five boroughs without a current HIC license.

1. Ask for the license number directly. A legitimate contractor should be able to provide this immediately. Hesitation or excuses are a red flag.
2. Try alternate names. They might be registered under a legal business name that differs from their trade name. Ask for the exact legal name on their license.
3. Check if licensing is even required.If you're in a part of New York with no local licensing requirement, the contractor may legitimately not have a license. In that case, focus even more heavily on insurance verification, references, and contract terms.
4. Verify they're not just "in the process." Some contractors claim they're "waiting on their license" or "in the renewal process." In NYC, it is illegal to perform home improvement work without a current, active HIC license. Period.
5. Consider it a dealbreaker in NYC.If you're in the five boroughs and the contractor has no HIC license, walk away. There is no gray area here. The law is clear, and the risk to you is real.

What does New York's Home Improvement Contractor Act require?

New York State's Home Improvement Contractor Act sets minimum contract standards for residential work statewide, even though it does not create a state license. Any home improvement contract over $500 must be in writing and include the contractor's contact information, a detailed scope of work, total price, payment schedule, start and completion dates, and a three-day cancellation notice.

New York State does have a law called the Home Improvement Contractor Act, but it does not create a state license. What it does is set minimum standards for home improvement contracts statewide. Under this law, any home improvement contract must:

• Be in writing if the total cost exceeds $500
• Include the contractor's name, address, and phone number
• Describe the work to be performed in detail
• State the total price and payment schedule
• Include start and estimated completion dates
• Include a notice of the homeowner's right to cancel within three business days

This law applies everywhere in New York State, regardless of whether your locality requires a license. If a contractor refuses to put the agreement in writing or won't include these details, that's a problem regardless of their licensing status.

Quick-reference: where to verify New York contractor licenses by location and trade

Use this checklist to find the right database for your situation. The correct agency depends on where the project is located and what type of work is being performed.

• NYC general contractor / remodeler: NYC DCWP - Home Improvement Contractor license
• NYC electrician: NYC DOB - Licensed Master Electrician or Special Electrician
• NYC plumber: NYC DOB - Licensed Master Plumber
• Westchester County: Westchester Dept. of Consumer Protection
• Nassau County: Nassau Office of Consumer Affairs
• Suffolk County: Suffolk Dept. of Consumer Affairs
• Other areas: Check your local city clerk or building department for requirements
• All locations:Verify insurance and workers' comp through the NY Workers' Compensation Board

The bottom line

Checking a contractor's license in New York is harder than it should be. There's no single website to visit, no statewide database to search. You have to know which agency handles licensing in your specific area and then navigate their individual verification systems.

But the effort is worth it. In NYC alone, the DCWP regularly takes action against unlicensed home improvement contractors, and homeowners who hire them have almost no recourse when things go wrong. No license means no bond, no regulatory oversight, and no easy path to resolution if the work is substandard or abandoned.

Take 15 minutes to verify before you sign anything. Know which database applies to your location, confirm the license is active, check for complaints, and verify insurance. It's the most important due diligence you can do before letting someone start tearing apart your home.
