Working in New York City: contractor permits, licenses and city rules

New York City regulates service businesses through several separate agencies, and each one has its own application. Everything here comes from the city's own offices as of October 2026. Treat it as general information, not legal advice, since the agencies revise fees and forms often.

Which rules are the city's and which are New York State's

Keep the layers apart, because owners mix them up and pay twice or skip a step.

The state layer is covered on our New York page and in the New York contractor licenses guide. Everything below is the city layer.

The home improvement license covers a long list of residential work

The Department of Consumer and Worker Protection says anyone doing construction, repair, remodeling or other home improvement work on residential land or buildings in the city needs a Home Improvement Contractor license. DCWP's checklist names basements, driveways, fences, garages, landscaping, patios, porches, sidewalks, pools and terraces. If you build fences or lay patios for homeowners in Queens, you are inside the rule even if you never touch a building.

The application asks for more than a form:

• Fingerprints for sole proprietors, partners, officers, principals and members, taken through IdentoGO.
• A sales tax ID or application confirmation number, plus proof of your business address and each owner's home address.
• A workers' compensation certificate that names DCWP as certificate holder, or a Certificate of Attestation of Exemption from the state Workers' Compensation Board. DCWP says ACORD forms are not accepted.
• EPA lead certifications (Renovation, Repair and Painting plus Lead-Based Paint Activities) or a signed affirmation that they do not apply to your work.
• A passed Home Improvement Exam: 30 questions, 21 correct to pass. The fee includes two attempts, and a retake after two failures costs $50.

The fee depends on the month you apply

The license term is two years and runs to February 28 of an odd-numbered year. DCWP's fee schedule, as listed in October 2026, steps down as the cycle runs:

Card payments carry a 2% convenience fee. You must also pick one of two protections for homeowners: enroll in the Home Improvement Business Trust Fund for $200, or post a $20,000 surety bond that names DCWP. DCWP says participants who stay in the Fund do not pay again at renewal if the Fund exceeded $2 million as of the prior July. The bond route needs your business name, DBA and premises address to match across every document.

The Department of Buildings licenses the trades and registers general contractors

The Department of Buildings is a separate office from DCWP. It states that general contractors must register to pull permits and supervise construction or demolition, under Article 418 of the Administrative Code. The renewal cycle and fee are on DOB's registration renewal page, so check your registration card for your expiration date. DOB's own project pages add two display rules: a registrant needs a place of business in the city, and must put its license number and business information on trucks, business cards and advertisements.

For one-to-four-family homes, DOB says a Home Improvement Contractor license is required in addition to the general contractor registration. Two trades are tied to named individual licenses:

• Plumbing. Ordinary plumbing work that needs no permit is reported by a licensed master plumber on DOB's monthly OP128 report, so a handyman or crew lead cannot do plumbing under your own license. Confirm with DOB what counts as ordinary work.
• Electrical. A Master Electrician License is needed to request an electrical construction permit or do the work in the city. A Special Electrician License covers workers employed by a building owner. Electrical work needs its own permit before work begins.

A painter, power washer or landscaper rarely touches these, but the HIC license and its bond still apply. Our contractor license guide explains how the pieces fit across states.

Hauling commercial waste is licensed by the Business Integrity Commission

Junk removal and cleanout crews meet a rule that does not exist in most cities. The BIC says anyone who removes, collects or disposes of trade waste from businesses in the city needs a Trade Waste Removal License, and it counts construction and demolition debris as trade waste. The license lasts two years. The BIC's fee list, as shown on the city's business portal in October 2026:

The BIC's portal page does not list a separate construction debris registration. City law lets a business that hauls only construction and demolition debris apply to the commission for an exemption from the license and a registration instead, and the commission reviews the applicant's character and integrity, so approval is not automatic. Ask the BIC whether that route fits you. If your work is cleaning out apartments or storefronts, call the BIC Licensing Center at (212) 437-0555 before you buy a truck. Our junk removal start-up guide covers the national side.

Construction hours and noise plans

The Department of Environmental Protection says construction on your property is allowed from 7 a.m. to 6 p.m. on weekdays. Any other time, including all weekend hours, needs after-hours authorization through the Department of Buildings or the Department of Transportation. Every person or business doing construction must prepare a Construction Noise Mitigation Plan before starting, check the box saying so on the DOB permit application, and keep a copy on site for inspectors. Where a perimeter barrier is required, DEP specifies a Sound Transmission Class rating of 30 or higher and a height no greater than 15 feet. The DEP page lists no fine amounts, so ask your DOB permit contact what a violation costs.

Calling before you dig

New York 811 serves the five boroughs plus Nassau and Suffolk Counties. Its excavator page says to give notice at least two working days and no more than 10 days (excluding weekends and legal holidays) before you start, utilities then have two working days to mark, and demolition needs a pre-demolition conference request at least seven working days ahead. Mark-out requests go to 811 or (800) 272-4480. Rule 753 is state law enforced by the Public Service Commission. New York 811 tells contractors excavating on commercial or residential property to notify the one-call center, so plan on a ticket for a fence-post job in a Staten Island backyard and confirm with 811 if you are unsure.

The Unincorporated Business Tax

If you run as a sole proprietor, partnership or an LLC taxed as a partnership, the city's Department of Finance lists a 4 percent Unincorporated Business Tax on taxable income allocated to the city. Employees are exempt, and S corporations fall under a different city tax. The portal does not state a filing threshold, so ask Finance or your accountant whether your gross income triggers a return. Corporations and LLCs taxed as corporations use the business corporation tax instead.

Climate and the busy season

The National Centers for Environmental Information's 1991 to 2020 normals for Central Park show an annual average of 29.8 inches of snow and 49.52 inches of precipitation. January averages a high of 39.5 and a low of 27.9 degrees, with 8.8 inches of snow, and July averages a high of 84.9. February is the snowiest month at 10.1 inches. Exterior painting and washing cluster between May and October, and plowing contracts are a winter business even though the city is mostly paved. In New York State, snow removal is a taxable maintenance service, per the state data on our New York page.

What this means for your website and phones

Put your license numbers where customers look first. DOB requires registered general contractors to show their number on trucks, business cards and advertisements, and a website is an advertisement. A site that lists the boroughs you actually serve, your license and your bond or Trust Fund status answers the first questions a Brooklyn homeowner asks. See our website service for how we build that, and keep your own call recordings lawful: New York is a one-party state, covered in our recording guide.

Ask DCWP, DOB, the BIC and the Department of Finance to confirm any fee or form before you pay it.
