Which NYC Metro Contractor License Do You Actually Need

New York has no statewide contractor license, so "am I licensed for this job" is really a jurisdiction question. The five boroughs run on DCWP and DOB. Nassau, Suffolk, Westchester, and Yonkers each run their own county or city license. New Jersey runs a separate state registration. None of them cover each other's territory.

If your business only ever works inside one of these lines, one license covers you. The costly mistake is assuming a license from one jurisdiction travels with you into the next one — it doesn't, and the sections below cover what each place actually checks before you can legally pull a permit or sign a contract there.

NYC splits contractor licensing between two agencies, and mixing them up is the single most common way a five-borough contractor ends up unlicensed for a job they thought they were covered for. The Department of Consumer and Worker Protection (DCWP) licenses general home improvement work — remodeling, renovation, repair, and structural alteration of residential buildings. The Department of Buildings (DOB) licenses specific trades: plumbing and electrical, plus the general contractor registration required to pull New Building permits for one- to three-family homes.

A DCWP Home Improvement Contractor license costs $200 for a full two-year term, though DCWP prorates the fee down to as little as $50 depending on where you fall in the licensing cycle. That fee covers up to two exam attempts (30 questions, 21 correct to pass); after two failures, $50 buys two more attempts. You also need either a $20,000 surety bond or a $200 DCWP Trust Fund enrollment. Every HIC license expires on February 28 of odd-numbered years regardless of when you applied — DCWP does not stagger expiration dates by application date, only the fee.

Red flag: a contractor quoting a home improvement job who can't produce a DCWP license number is operating illegally, full stop — unlicensed home improvement work is a misdemeanor carrying up to six months in jail, a $1,000 fine, or both for each violation, plus a civil penalty of up to $1,000 per violation, and DCWP can seize vehicles used in the work. Action: before signing, verify the license number against DCWP's public lookup rather than taking a business card at face value.

Plumbing runs on a different track entirely. A Master Plumber license from DOB requires 7 of the last 10 years working under a Licensed Master Plumber, including at least 2 years as a registered journeyman plumber, before you can sit for the exam, plus a physical exam (LIC62 form) completed within 90 days before you submit the background application. The license runs three years at $200 to apply and $225 to renew ($150 license renewal plus $75 seal renewal), with 7 hours of continuing education required each cycle. Miss the renewal window and the late fee is $50 for the first 30 days, then $100 up to one year late.

NYC has no standalone roofing license. DOB's general contractor registration — $300 to apply and $240 to renew every three years, with a $50 late-renewal fee — applies to contractors pulling New Building permits for one- to three-family homes. Residential repair and re-roofing is typically home improvement work, which points to the DCWP HIC license instead. Red flag: a roofer who says "roofing doesn't need a license in New York" is dodging the question — no state roofing credential exists, but residential roofing work needs the DCWP HIC license, and new one- to three-family construction needs DOB registration. Action: confirm with DOB and DCWP which credential your roofing job needs, and ask the contractor for that license or registration number before work starts.

Nassau County's Consumer Affairs office issues a two-year home improvement license for a $650 application fee, plus a one-time $50 restitution-fund contribution due only when you first apply — renewal is the flat $650 with no separate fee published. There's no written exam. What trips contractors up is the late-renewal math: renew more than 15 days late and Nassau adds a $110 late fee; more than 90 days late, you need an appointment with the Commissioner to ask permission to renew; and past a full year, Nassau won't renew at all — you have to reapply as a brand-new applicant. Red flag: a Nassau contractor whose license shows a lapse of more than a year is not just late, they're currently unlicensed and mid-reapplication. Action: check the issue date against the license number, not just whether a number exists.

Suffolk County is the one jurisdiction in this group that requires a written exam, run through the Department of Labor, Licensing and Consumer Affairs (DLLCA). Suffolk charges a $200 application fee plus $200 per year of license term (County Code §563-19), so a new two-year license costs about $600 up front and each renewal costs $400. Bond or liability insurance is required at the Director's discretion rather than a fixed statewide minimum, and Suffolk doesn't publish a specific late-renewal fee — it states only that an expired license becomes void. Red flag: a Suffolk contractor who can't explain what insurance they're carrying is a bigger problem here than elsewhere, since there's no floor number to check them against. Action: ask what the Director's office actually required for their file, in writing.

Westchester County's Department of Consumer Protection raised its home improvement license fee to $750 effective January 1, 2026, covering a two-year term — the same $750 applies to renewal. File the renewal more than 15 days before expiration to avoid the $50 penalty; Westchester refuses renewals filed more than 60 days after expiration, and you must then file a new application. No exam is required. Liability insurance is mandatory, in an amount the Director sets, and a bond of up to $50,000 may be required. Operating without a license is a Class A misdemeanor, though Westchester's code doesn't publish a specific fine amount for the offense. Red flag: a Westchester quote that still cites a pre-2026 fee is a sign the contractor hasn't renewed under the current schedule. Action: confirm the license was issued or renewed at the $750 rate, not an older number.

The City of Yonkers requires its own license on top of — not instead of — any Westchester County registration; Westchester's own materials flag this explicitly for contractors taking jobs in Yonkers. The application fee is $400, non-refundable, for a two-year term. Yonkers bills two separate add-on fees that are easy to mix up: a $25 supplementary license fee per additional business location, and $10 per additional vehicle beyond the first three (which come with bumper stickers included). General liability insurance ($500,000 minimum) and workers' compensation are both required; Yonkers publishes no exam requirement, no bond requirement, and unlike the other three jurisdictions, no separate published renewal fee or late-renewal penalty. Red flag: a Yonkers-based contractor citing only a Westchester County license as their credential for city work is missing a second, mandatory registration. Action: confirm the Yonkers Office of Licensing has an active file for the business, separate from the county license — and don't assume a published renewal figure exists where Yonkers hasn't posted one.

New Jersey handles this completely differently from New York's patchwork of county and city licenses — it's one state-level registration that covers the whole state, run by the Division of Consumer Affairs under the Home Improvement and Home Elevation Contractor Licensing Act (P.L. 2023, c.237). A Home Improvement Contractor Registration costs $110 to register initially and $90 to renew annually — a shorter, cheaper cycle than any of the NYC-area counties, but it renews every single year instead of every two or three.

The bond requirement is where New Jersey differs most from its neighbors: instead of one flat bond amount, the compliance bond is tiered by how much work you actually do. A single contract under $10,000 (or trailing 12-month volume under $150,000) needs a $10,000 bond; a contract between $10,000 and $120,000 (or volume between $150,000 and $750,000) needs $25,000; anything larger needs $50,000. General liability insurance ($500,000 minimum per occurrence) and workers' compensation are both required unless you're a sole proprietor with no employees.

Registrations run April 1 through March 31. A renewal that reaches the Division after the due date printed on the form adds a $25 late fee, and reinstating a registration the Division has suspended carries a $50 fee (N.J.A.C. 13:45A-17.10, 17.14). Red flag: a contractor who knowingly operates on a lapsed registration commits a fourth-degree crime under N.J.S.A. 56:8-146, on top of Consumer Fraud Act civil penalties. Action: check the registration's expiration date directly, since a lapsed registration is a criminal exposure issue for the contractor, not just a paperwork gap.

Most licensing gaps in this metro area happen at the boundary lines, not inside a single jurisdiction. Three scenarios cover the majority of the cases that come up:

1. A Queens-based remodeler books a Nassau job. Their DCWP HIC license covers Queens. It does not cover Nassau. They need Nassau's separate $650 home improvement license before they can legally sign that contract, and Nassau treats an unlicensed business the same as a local one that never registered — unlicensed operation is a Class A misdemeanor, and the County may also impose a civil penalty of up to $5,000 per violation.
2. A Westchester-licensed contractor picks up work in Yonkers. Westchester's license does not extend into Yonkers even though Yonkers sits inside Westchester County. Yonkers requires its own $400 license on top of the county one — this is the single most-missed license in the entire metro area because it looks redundant on paper and isn't.
3. A New Jersey contractor takes a job on Staten Island. NJ's Division of Consumer Affairs registration has no jurisdiction in New York City. Staten Island is one of the five boroughs, so this contractor needs a DCWP HIC license — a different agency, different fee structure, different renewal cycle — before they can start.

The pattern across all three: proximity doesn't create coverage. A license is valid only in the specific jurisdiction that issued it, and the NYC metro area packs seven separate licensing authorities into commuting distance of each other.

1. Confirm the job site's jurisdiction first, not last. Five boroughs, Nassau, Suffolk, Westchester, Yonkers, and New Jersey each require a separate license — check before you quote, not after you're on site.
2. Match the license to the trade, not just the location. Inside NYC, general remodeling needs a DCWP HIC license; plumbing and New Building permits for one- to three-family homes route through DOB instead.
3. Track renewal dates by jurisdiction, not by memory. DCWP expires every two years on a fixed February 28 date regardless of application date; DOB plumbing runs three years; New Jersey renews annually. Every jurisdiction in this guide runs its own clock — track them separately, not against one renewal date.
4. Verify Yonkers' renewal fee directly before budgeting — Yonkers hasn't published a separate renewal fee at all.
5. Don't assume a subcontractor's license travels with them. A sub licensed in Nassau working your Suffolk job needs their own Suffolk license — check it the same way you'd check your own.
