New York Contractor License: Requirements, Cost and Exams

The qualifier rule

Qualifying individual model

New York does not license companies through a qualifying individual at the state level, because there is no state license. Inside New York City, the DOB General Contractor Registration is held by an individual. Whether, or how many, companies one registered individual may be tied to is not stated in the board materials reviewed for this page; confirm this directly with DOB rather than assuming a limit. The same caution applies to replacement rules and deadlines if a registered individual leaves a company. A deadline or grace period for replacing that individual is not stated in the board materials reviewed for this page.

Exams

NASCLA

New York is not listed among the jurisdictions accepting the NASCLA Accredited Commercial Building Contractor exam (NASCLA). This fits a consistent pattern: NASCLA acceptance is granted by a state contractor licensing board, and New York has no state contractor licensing board to grant it. Passing the NASCLA exam does not provide any licensing benefit in New York.

Fees and timeline

Application timelines

NYC DOB states that an approved General Contractor Registration applicant has one year from the date of approval to pick up the registration (City of New York website). A typical processing time for the registration itself, or for the Nassau, Suffolk, or Westchester licenses, is not stated in the board materials reviewed for this page.

Reciprocity

Reciprocity and exam waivers

No reciprocity or exam waiver agreements between New York and other states for general contracting are stated in the board materials reviewed for this page. This follows from New York having no state general contractor exam for another state to waive into, and no New York exam to waive elsewhere. Reciprocity into or out of New York should not be promised for general contracting. Trade reciprocity would need to be checked city by city and county by county; none is confirmed in the board materials reviewed for this page.

What changed

What changed

The most significant change is statewide rather than local. Effective December 30, 2024, the New York State Department of Labor (NYSDOL) requires contractors and subcontractors who bid on or perform public work projects, and certain private projects covered by Article 8 of the New York Labor Law, to register with NYSDOL through its Contractor Registry portal before submitting a bid or starting new work (dol.ny.gov). This is a registration, not a license, and it applies on top of the local licensing described below, not in place of it. The registration fee is $200, discounted to $100 for certified minority or women owned businesses, and a certificate of registration is valid for two years (dol.ny.gov). Civil penalties for bidding or working without this registration can run up to $1,000 per project (dol.ny.gov). Starting December 31, 2025, covered contractors must also submit certified payroll records through the same NYSDOL portal (dol.ny.gov). The local nature of general contractor licensing in New York described below has not changed.

The board

Who licenses general contractors

General contractor licensing and home improvement contractor licensing in New York are handled city by city and county by county, not by a single state board. New York City runs its own program through the Department of Buildings, commonly called DOB (City of New York website). Nassau County, Suffolk County, and Westchester County each run their own separate home improvement licensing through their own consumer affairs or consumer protection departments (Nassau County New York government, suffolkcountyny.gov, westchestergov.com). A license or registration in one of these jurisdictions does not transfer to another. A contractor working across New York City, Nassau, Suffolk, and Westchester needs four separate credentials.

New York City Department of Buildings General Contractor Registration

This registration is required for contractors who build one, two, and three family homes and need a DOB new building permit (City of New York website). The registration is held by an individual applicant who must be at least eighteen years old, able to read and write English, and of good moral character, and the registration process includes a background investigation (City of New York website). There is no written exam for this registration. The process is a notarized application (forms LIC6 plus LIC50 or LIC51) and a background check, not a test (City of New York website). The financial requirement is proof of a bank balance of at least $25,000 held for the three months before application, shown through consecutive bank statements or a notarized bank letter (City of New York website). The insurance requirement tied to this registration is a general liability policy with a minimum of $1 million, plus workers compensation and disability insurance (City of New York website). The registration fee is $300, the renewal fee is $240, there is also a background investigation fee of $330, and the registration term is three years (City of New York website). Corporations must also submit a Certificate of Incorporation from the New York State Department of State and a Certificate of Good Standing (City of New York website). Whether one individual can hold this registration while tied to more than one company is not stated in the board materials reviewed for this page; confirm this directly with DOB. This registration is specific to one, two, and three family residential new building work. DOB's own page on this registration does not extend it to commercial general contracting, and a broader DOB license for commercial general contractors is not stated in the board materials reviewed for this page. Commercial general contractor work in New York City should be treated as governed by contract and insurance terms, plus whatever DOB licensed trade or safety role applies to the specific scope.

NYC trade licensing

Inside New York City, DOB issues its own Master Plumber license, which requires passing both a written and a practical examination, plus documented experience of at least seven years within the prior ten years under the supervision of a licensed Master Plumber, with at least two of those years as a DOB registered Journeyman Plumber (City of New York website). HVAC work on residential property is folded into the local Home Improvement Contractor license rather than a separate HVAC license in most of these jurisdictions (budgetheating.com).

Nassau, Suffolk, and Westchester home improvement licensing

Suffolk County requires a Home Improvement license through its Department of Consumer Affairs, which includes a multiple choice written exam, proof of liability insurance of at least $500,000 combined bodily injury and property damage, proof of workers compensation coverage or an exemption, and a $200 application fee (suffolkcountyny.gov, getjobber.com). Operating without a Suffolk County home improvement license carries a fine of up to $750 for a first violation and up to $1,500 for each later violation (suffolkcountyny.gov). Nassau County licenses home improvement contractors through its Department of Consumer Affairs. The application must be notarized, and the county requires corporate filing documents from the New York Department of State plus proof of workers compensation coverage (Nassau County New York government). Westchester County requires registration under its county law governing home improvement businesses, run through its Department of Consumer Protection, with a background check on every license holder. Penalties for operating without a license start at $1,000 for a first offense and rise to $5,000 and then $10,000 for repeat offenses within ten years, plus possible Class A misdemeanor charges (westchestergov.com). Whether any of these three counties accept NASCLA or offer an exam waiver tied to another state's exam is not stated in the board materials reviewed for this page; confirm directly with the specific county office before assuming either applies.
