What New York law gives you against a problem contractor
New York's home-improvement statutes are more contractor-hostile than most states realize. The General Business Law sets a clear floor for what every contractor must do before touching your property, and when they fall short, the floor becomes the foundation of your claim.
N.Y. Gen. Bus. Law § 771 requires a written contract for any home-improvement project exceeding $500. That contract must include the contractor's name, address, and license number, a detailed scope of work, total price, payment schedule, and projected start and completion dates. The contractor must also hand you a Notice of Right to Cancel at signing, giving you three business days to walk away penalty-free. A contractor who skipped any of these requirements violated the statute before a single nail was driven.
N.Y. Gen. Bus. Law § 777 adds a licensing requirement with teeth. In New York City, contractors must be licensed by the Department of Consumer Affairs. Outside the five boroughs, local licensing authorities govern the same requirement. The consequence for skipping it is severe: an unlicensed contractor cannot enforce a contract for payment in New York courts. That means a contractor who took your deposit, started the work, then walked off has no legal claim to what you already paid, and you have a direct claim to recover it.
How long you have to act
The clock on a New York contractor dispute runs from the date of breach or the date the work was completed, whichever gives you the cleaner starting point.
For written contracts, CPLR § 213(2) gives you six years. Most home-improvement jobs that cost more than $500 should have a written contract under § 771, so six years applies in the majority of disputes. For oral agreements (jobs that were done on a handshake, or smaller jobs below the $500 threshold), CPLR § 213(4) allows four years from the breach.
Six years sounds like a long runway. It is not a reason to wait. Three things get harder with time: witnesses forget the sequence of events, text messages and emails get deleted, and the contractor may dissolve the business or become judgment-proof. The leverage in a demand letter is highest when the dispute is fresh. A letter sent two months after the contractor walked off carries far more urgency than one sent two years later.
If the contractor filed a mechanic's lien on your property under N.Y. Lien Law § 3, there is a separate urgency. Liens filed by contractors on residential property are valid for one year from filing unless foreclosed. Sending a demand letter and, if necessary, filing a counter-claim or a lien discharge action needs to happen well inside that window.
What you can actually recover
Your recoverable damages in a New York contractor dispute depend on what went wrong. Three main categories apply:
Actual damages. The difference between what you paid and what you received. If you paid $18,000 for a kitchen renovation and the contractor walked off after delivering $6,000 worth of completed work, your actual loss is $12,000. If the work was done badly enough that you had to pay a second contractor to rip it out and redo it, the cost of remediation is added to the actual damages.
Return of payments from an unlicensed contractor. Under N.Y. Gen. Bus. Law § 777, an unlicensed contractor has no right to retain any payment. You can demand back every dollar paid, not just the portion corresponding to unfinished work. This is the strongest recovery position in the statute and the argument most likely to produce quick payment once cited in a letter.
Treble damages and attorney's fees under § 349. If the contractor's conduct was deceptive, meaning they misrepresented their license status, inflated their credentials, promised a timeline they had no intention of meeting, or used substandard materials while charging for premium ones, § 349 makes them liable for three times your actual damages plus civil penalties and attorney's fees. You do not need to file a lawsuit to raise § 349 in a demand letter. Citing it with specifics about the deceptive conduct, and naming the treble-damages consequence, is often enough.
Evidence you'll need before you write the word one
A demand letter is only as strong as the facts behind it. Before you draft anything, pull together every document that speaks to what was promised and what was actually delivered.
The contract itself. If you have a signed written agreement, that is your primary evidence. Review it for the line items required under § 771: contractor name, address, license number, scope, price, timeline, and payment schedule. Every missing element is a violation. If you only had an oral agreement, document that fact, because it positions the contractor as having violated § 771 on a job over $500.
License verification. Search the NYC Department of Consumer Affairs database at nyc.gov/dca (for NYC jobs) or your local licensing authority (for upstate work). A printout showing no valid license is compelling evidence that § 777 applies. Do this before you write the letter.
Payment records. Bank statements, check copies, wire confirmations, Venmo or Zelle records, anything that shows how much you paid and when. Amounts and dates matter.
Photographs and video. Document the current state of the work with dated photos. If the work was done poorly, photograph it against any written specification in the contract. If the contractor walked off mid-project, photograph what was left unfinished.
Communications. Every text, email, voicemail transcript, and written note matters. Specific promises about timelines or materials made in writing are the foundation of a § 349 deceptive practices argument. If the contractor told you via text that they were "fully licensed" and the DCA search shows otherwise, that text is your strongest single piece of evidence.
Estimates and invoices from a remediation contractor. If you needed a second contractor to complete or correct the work, get a written estimate that specifically identifies what was wrong and what it costs to fix. This establishes the actual damages figure precisely.
Writing a New York contractor dispute demand letter that gets paid
New York contractors respond to demand letters that cite specific statutes, name specific amounts, and set a firm deadline. Vague letters that say "you owe me money" do not move anyone. Here is the structure that works.
Opening paragraph: the facts, only the facts. Name the parties, the property address, the contract date (or the date work began if no written contract exists), the total amount paid, and the current state of the work. Keep this to three sentences. No adjectives.
Statutory violations, itemized. List each violation separately and cite the specific section. "The contract you provided does not include your license number, in violation of N.Y. Gen. Bus. Law § 771." "Your company does not appear in the NYC DCA licensed contractor database, in violation of N.Y. Gen. Bus. Law § 777, which voids your ability to enforce any claim for payment." "Your representation on [date] that the work would be completed by [date] was not honored, a misrepresentation under N.Y. Gen. Bus. Law § 349." Each violation gets its own line.
The demand. State the exact dollar amount you are demanding and the basis for it. "I demand the return of $14,500, representing the full amount paid to your company, on the grounds that you performed the work without the required license." Or, for completed but defective work: "I demand $9,200, representing the cost to remediate the deficient work as quoted by [second contractor] on [date]."
The deadline. Give 14 calendar days from receipt. Not "promptly" or "in a timely manner." A specific date.
The consequence. State plainly that failure to respond will result in a small claims or civil court action seeking actual damages plus treble damages under § 349, civil penalties up to $500 per violation, attorney's fees, and court costs. Name the small claims limit ($10,000 in NYC and City/District Courts) or note that claims above that threshold will be pursued in civil court. The concrete escalation path makes the deadline real.
Send it certified. The letter goes via USPS Certified Mail with tracking. Keep the tracking confirmation. An attorney-reviewed demand letter sent by certified mail is evidence, not just correspondence, and it changes how the other side responds.
If the contractor ignores the letter
Most contractors pay or negotiate once a properly cited demand letter arrives. Some do not. If your deadline passes with no response, file a New York small claims case against a contractor as the next step.
New York small claims courts (including NYC Small Claims Court, City Courts, and District Courts) handle cases up to $10,000. Town and Village Justice Courts outside NYC are limited to $3,000. If your actual damages plus the treble-damages multiplier under § 349 push your claim well above $10,000, a regular civil court filing is the appropriate venue, and the attorney's-fees provision in § 349 makes that economically viable even for smaller actual-damage amounts.
What happens after you send the letter
A demand letter sent by USPS Certified Mail typically delivers within two to five business days. The 14-day response window starts from receipt, which the tracking confirmation establishes. Here is the usual sequence:
Days one through seven after delivery: silence. This is normal. The contractor may be consulting whoever advises them, looking up the statutes you cited, or simply deciding whether to fight.
Days eight through twelve: most responses come in this window. Common outcomes include a settlement offer (almost always below your demand, almost always negotiable), a request to meet and discuss the scope, or a dispute about specific charges. Respond in writing and keep the deadline in your reply.
Days twelve through fourteen: if you've heard nothing, send a brief follow-up via email or text referencing the letter and confirming the deadline. This is not legally required, but it eliminates the "I never got it" defense and produces a second documented touchpoint.
After the deadline: if the contractor still has not responded, you have a complete paper trail, a certified mail confirmation, a demand citing specific New York statutes, a stated damages figure, and a specific deadline that was not met. That documentation is the foundation of your court filing. Most New York judges in small claims treat a well-documented demand letter as evidence that you tried to resolve the dispute before coming to court, which typically helps your case.
