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

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.
The jurisdictions that require a license
Outside New York City, several local jurisdictions require home improvement contractor licensing: Nassau County, Suffolk County, Westchester County, Putnam County, Rockland County, and the City of Buffalo. Each runs its own program through its local consumer affairs or consumer protection office — Nassau, Suffolk, and Westchester all have separate exams, fees, and insurance minimums.
On documents: Westchester County requires licensed home improvement contractors to include their license number on all advertisements, contracts, invoices, proposals, and stationery. Suffolk County has similar contract display requirements. The specifics differ by jurisdiction — verify the rules for wherever you’re working.
One rule applies statewide regardless of license requirements: under New York General Business Law Article 36-A, any home improvement contract over $500 must be in writing and signed by all parties.
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, or most other parts of New York State outside the jurisdictions listed above? No local home improvement contractor license is required for private residential work. Local towns and villages may have their own permit or registration requirements — check with the building department in the specific municipality before you start.
The new 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. 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 manually tracking 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.
