Home improvement licenses in Nassau County come from the county’s Department of Consumer Affairs in Mineola, which enforces Title D-1 of the Nassau County Administrative Code. The main requirements are a notarized application, five years of documented experience, liability insurance, workers’ compensation proof, business records and a fingerprint check, with $650 for a two-year license and a separate, one-time $50 restitution fund fee paid at filing.
Requirements, fees and forms checked against Nassau County and New York State sources, plus the Suffolk, New York City and Westchester agencies for the comparison table, as of October 2026. This is general information, not legal advice; confirm details with the county before applying.
Who issues the license, and under which law
The Nassau County Department of Consumer Affairs (DCA), which the code also calls the Office of Consumer Affairs, works from the third floor of 240 Old Country Road in Mineola, NY 11501. Questions go to (516) 571-2600 or consumeraffairs@nassaucountyny.gov; as of October 2026 front desk hours run 9:00 a.m. to 4:30 p.m., with sign-in closing at 4:15 p.m. The license rests on sections 21-11.0 through 21-11.16 of the Nassau County Administrative Code, first enacted as Local Law No. 6-1970, and on the Rules and Regulations Relating to the Home Improvement Business, last amended in October 2026.
Who needs a Nassau County home improvement license
Anyone in the business of repairing, remodeling or adding to homes for up to three families needs one, including yard and outbuilding work. The code’s examples run from painting and chimney sweeping to pools, paving, demolition and mold cleanup, and landscapers are covered once they haul their own equipment in their own vehicle. The Who Must Be Licensed page adds general contractors, roofers, masons and solar installers. Title D-1 sets no minimum job price.
Salespeople who visit Nassau homes or sign contracts for a licensed firm register on the Salesperson Registration Application, and every owner, officer, director, member, stockholder and manager, plus any employee or salesperson with power to estimate or negotiate a contract, files a notarized disclosure form.
Who does not need one
- Firms that take only commercial jobs.
- Workers on a licensed contractor’s payroll.
- Architects, engineers, plumbers and electricians working inside their own credential; in Nassau, plumbing and electrical credentials come from the towns, cities and villages, not the county.
- New home construction.
- Material sales with no installation.
- Decorating unrelated to an improvement job.
- Homes owned by the state or a municipality.
- Fire and burglar alarm systems.
Handyman work
Nassau has no handyman license as such; the job list decides. Carpentry, painting, drywall, tile and windows are home improvement work, and the county’s Rule 18 lists “handyman” among home improvement trades. Lighter chores such as odd repairs, gutter cleaning, screen mending, smoke detector installs and junk hauling belong to a separate home services license (code section 21-25), and the Fees page has no separate line for a new home services license; its catch-all for other new business licenses is $650, so confirm the figure with DCA.
County license versus town and village permits
Cities, towns and villages still control building permits, plan approval and inspections. The county FAQ makes the contractor responsible for confirming that permits exist before work starts, whoever files them.
What the county requires
- Age and premises. Applicants must be at least 18 and run the business from a genuine New York State address. Answering services and mail drops such as P.O. boxes do not count.
- Experience. Someone at the top of the firm proves five recent years in the field with W-2 or 1099 tax forms or a license from another municipality.
- Clean record. DCA searches the firm and its people for debts. Judgments tied to the trade, tax liens and warrants, and unpaid child support all count. Each must be paid, vacated, under appeal or a motion to vacate, or on a payment plan with up-to-date payments. Each disclosure form also asks about criminal convictions, pending charges and lawsuits, bankruptcies and money owed to the county. Unpaid DCA fines must be paid off, and open complaints resolved.
- Tax ID and bank. A federal EIN and a business bank account are both mandatory.
- Liability insurance. At least $250,000 per person and $500,000 per occurrence for injuries, and $100,000 for property damage, with DCA named as certificate holder. Vague trade labels such as “General Contracting” are rejected, and farmed-out trades follow the words “subcontracting of.” Kitchen and bathroom remodeling, dormers and extensions, fire sprinklers, house lifting and solar are trades the commissioner says require subcontracting, so those certificates must list it, and deductibles are not accepted.
- Workers’ compensation. Employers file Form C-105.2 from a private carrier or Form U-26.3 from the State Insurance Fund. Firms with no employees, day laborers, volunteers (family included) or subcontractors file the CE-200 exemption, requested through New York Business Express from the Workers’ Compensation Board’s CE-200 page, except in trades the county treats as two-person work, such as roofing, kitchens and bathrooms.
- Disability and Paid Family Leave. The packet lists only workers’ compensation forms, but the state Workers’ Compensation Board says Workers’ Compensation Law section 220(8) makes counties confirm it too; employers with a disability and Paid Family Leave policy should be ready to show Form DB-120.1.
- Trade certificates. Trades on the Rule 18 list, which includes carpentry, painting, roofing, siding, windows, doors, kitchens, baths and handyman work, need at least one owner or principal holding a current lead-safe renovator (RRP) certificate from an EPA-accredited trainer, with that person’s photo on it. Irrigation, pool, solar and mold remediation firms need extra credentials, and house lifting firms need $1 million per occurrence and $2 million aggregate liability plus riggers coverage.
- Fingerprints. New applicants have been fingerprinted since July 1, 2024. It covers sole owners, partners, corporate officers, directors, stockholders holding more than 5%, LLC members and an out-of-state firm’s New York contact person. IdentoGO takes the prints after DCA’s final review, for about $90, paid once.
How to apply, step by step
- Collect business filings. A corporation or LLC proves it exists with its Department of State filing receipt. Sole owners and partnerships need a certified County Clerk certificate. A corporation or LLC using a DBA also needs its state Assumed Name Certificate. Out-of-state firms add a Certificate of Authority, a New York address and an in-state contact person.
- Pick the trades and insure them. Mark every trade on the Home Improvement Work (Circle) Sheet. The broker’s certificate must mirror those trades.
- Fill in the forms. Download the Home Improvement License Application and the Disclosure Form for Home Improvement from the Licensing / Registrations page. Each disclosure needs two 2×2 passport photos and a New York driver license or non-driver ID. Add proof of home address. Notarize both forms.
- Cut two payments. One for $650 and one for $50, never combined, each a money order, certified check or official bank check made out to “The County of Nassau.”
- Confirm how to file. The packet does not say how to deliver a first application. DCA’s Welcome page says its front desk staff help contractors submit license applications, and renewals go by mail or through the county’s online portal, so confirm the route with the licensing desk first.
- Get fingerprinted once DCA sends instructions.
- Wait for the license. Filing allows nothing: no jobs, ads or sales calls until the mailed license arrives. It then hangs at each business site, with copies riding in every work truck.
How long it takes. No typical turnaround is published, but section 21-11.12 gives the commissioner 90 days after a complete filing to decide, with written reasons for any refusal. Under section 21-11.6, a denied applicant is due back half the fee paid once the commissioner approves the refund and the Comptroller audits it, and Rule 29 charges $250 when the commissioner reverses a denial.

Renewing a license
A license lapses at the end of the 24th month after issue, and renewal costs $650 for two more years. The Renewal Instructions allow two routes. The Licensing / Registrations page posts these instructions but no blank renewal form, so a contractor without one can renew through the online portal or email consumeraffairs@nassaucountyny.gov. Paper renewals need a check or money order. The online portal takes credit cards and scanned documents.
- Late renewals run on a clock: more than 15 days after expiration adds the $110 late fee; after three months, renewal needs the commissioner’s permission, sought at an appointment; after one year, the license cannot be renewed. An allowed late renewal keeps the original expiration date.
- Bring fresh insurance matching the licensed trades, workers’ compensation proof, bank details and, for Rule 18 trades, a current RRP certificate; one with fewer than 30 days left before it expires is refused.
- Since 2025, renewing holders not yet printed must be fingerprinted too.
- A pending fund claim freezes renewal. So does any fund payout left unpaid.
Report changes to DCA in writing right away; the code says immediately, and the application forms set a ten-day limit. Owners, officers, address and scope all count, and instructions, plus the additional location and upgrade request forms, are on the Making Changes to a Current License page, while the address change and name change forms are listed on the Licensing / Registrations page.
How homeowners can check a license
DCA’s Search Businesses With Valid Licenses tool takes a license number, company name, street address or insurance coverage. Results give status, trades and insurance flags, for example “Not Insured for Kitchens & Bathrooms.” DCA says a contractor absent from the list holds no current license. Plumbers and electricians are not in it; ask the local building department. Complaint history is available by phone at (516) 571-2600.
Before signing, ask the contractor for:
- the Nassau license number, which must appear on contracts and ads;
- an insurance certificate in the homeowner’s name, due at signing;
- subcontractor names and license numbers;
- who is pulling the permits;
- a staged payment plan; the county’s consumer checklist calls a deposit under 15% fair.
Penalties for working without a license
Operating unlicensed, or carrying on after a suspension or revocation, is a class A misdemeanor under code section 21-11.15, and each violation is charged on its own. State Penal Law section 70.15 caps jail for that class at 364 days, while the county FAQ still says one year. Civil penalties of up to $5,000 per violation can be stacked on top.
Officers may impound vehicles, tools and equipment tied to unlicensed jobs, and a hearing follows within five business days. The person cited cannot get them back without first applying for a license, though a vehicle owner who was not the violator can win release by paying the fines and costs and signing a sworn statement. Repeat findings within five years can end in forfeiture. For willful or dangerous violations, the commissioner can award the owner up to triple damages. Licensed firms using unlicensed subcontractors face a $1,500 fine.
Contract rules that protect Nassau homeowners
Every Nassau home improvement deal, change orders included, must be on paper and signed by both sides. County rules expect the firm’s contact details and license number, the salesperson’s name, the scope, materials by brand or model, the final price and a finish date, and the code allows at most 30 days’ grace beyond it.
County rules require a three-day cancellation notice in contracts signed away from the contractor’s place of business, printed in bold type of at least 10 points, with the contract written in the language mainly used in the sales pitch. State law, covered below, requires the notice in contracts over $500 regardless of where they are signed. The homeowner may back out by mail, text or email through the third business day, the firm must refund within 10 business days, and work may not start in that window unless the owner signs a dated emergency waiver.
State law adds a floor for jobs priced above $500, the threshold in General Business Law section 770, once a contractor’s home improvement contracts top $1,500 in any 12 months. Section 771 requires a signed, plain-English contract with:
- estimated start and substantial completion dates;
- the work, materials by make or model, and the price;
- a bold mechanic’s lien warning;
- notice that payments received before completion go into a Lien Law trust account unless the contractor posts a bond, contract of indemnity or irrevocable letter of credit;
- any progress payment schedule;
- the three-day cancellation notice;
- the insurer covering the work, with its phone number and address.
The owner gets a signed copy before work starts.
The county’s restitution fund helps homeowners who win but cannot collect. The cap is $10,000, and it applies only to judgments or arbitration awards against licensed firms. The homeowner must have complained to DCA first and must claim within two years after the judgment is filed with the County Clerk. Complaints go on the Consumer Complaint Form, by mail or in person.
How Nassau compares with Suffolk, NYC and Westchester
Each jurisdiction licenses work inside its own borders, so a Nassau license stops at the county line. Figures are from agency pages read in October 2026.

|---|---|---|---|
| Nassau (DCA) | $650 plus $50 restitution fee | Two years | None in the packet |
| Suffolk | $200 application fee, $200 per license year (county code section 563-19) and a one-time $100 restitution fund fee (section 517-2) | Two years | Written test |
| New York City (DCWP) | $200 for a full cycle, prorated by filing date, plus $200 Trust Fund or a $20,000 bond | Ends February 28 of odd years | 30 questions, 21 to pass |
| Westchester | $750 application fee since January 1, 2026; $100 expedited processing | Two years | Not stated in the 2026 application |
Frequently asked questions
Do you need a license to be a handyman in Nassau County?
Usually yes, though nothing is called a handyman license. Paid carpentry, painting, drywall or tile work on a home needs the home improvement license; lighter chores like gutter cleaning need the home services license.
How do you look up a contractor’s license in Nassau County?
Use the Search Businesses With Valid Licenses tool run by the Nassau County Department of Consumer Affairs (DCA). DCA treats a contractor missing from it as not currently licensed, though the search page asks users to call if a listing seems missing. DCA at (516) 571-2600 can confirm a listing and share complaint history.
How much is a home improvement license in Nassau County?
As of October 2026, a new two-year license costs $650. A separate $50 payment goes to the restitution fund, and fingerprints run about $90. Renewal is $650 every two years, plus $110 if filed more than 15 days late.
How long does it take to get a Nassau County home improvement license?
No typical processing time is posted. The code requires a decision within 90 days of a complete application, and fingerprinting follows DCA’s review, so apply early.
Is there a general contractor license in Nassau County?
Not a separate one. A general contractor working on Nassau homes needs the home improvement license, while purely commercial builders need no county license.
