1. Administrative Recovery: File a Complaint with the DCWP

If your property is located within New York City, your first step should be filing a complaint with the Department of Consumer and Worker Protection (DCWP). You can file directly online via the NYC DCWP Complaint Page. This costs you nothing.

• Licensed Contractors: Home improvement contractors operating in New York City are required to be licensed by the DCWP. If the original contractor held a valid license, the DCWP can investigate the dispute, facilitate mediation, and potentially help secure restitution or monetary recovery for the cost of necessary repairs.
• Unlicensed Contractors: If the contractor operated without a required home improvement license, DCWP enforcement can impose administrative fines or sanctions, or even refer the matter to a district attorney, but civil litigation will likely be required to recover your financial losses.

2. Court Remedies and the Unlicensed Contractor Bar

If the administrative avenue does not resolve the matter, you can pursue a lawsuit in Small Claims Court (for damages up to $10,000) or Civil Court (for damages up to $25,000). However, a contractor’s licensing status significantly impacts what monies can—and cannot—be claimed.

Under New York law, an unlicensed contractor is barred from suing to enforce a contract or collecting unpaid balances under contract or quantum meruit theories. Conversely, a homeowner who has already paid an unlicensed contractor cannot maintain a lawsuit simply to recover the contract price paid if they received the benefit of the work.

• No Restitution of the Original Contract Price: Under the long-standing doctrine that courts will leave the parties where they find them, you cannot sue an unlicensed contractor solely to force a refund of the original contract fee. In Segrete v. Zimmerman, 67 A.D.2d 999, 413 N.Y.S.2d 732 (2d Dept. 1979), the Appellate Division held that while an unlicensed contractor cannot recover for unpaid work, a homeowner who has had the benefit of the work is not entitled to recover payments already made.
• The Host v. Gauntlett Precedent: Similarly, in Host v. Gauntlett, 73 Misc. 2d 96, 341 N.Y.S.2d 201 (Civ. Ct. Queens Cty. 1973), the court held that an unlicensed home improvement contractor could not be compelled to return monies received merely because they were unlicensed. Rather, the homeowner’s proper remedy is to bring a claim for actual damages caused by defective or unworkmanlike performance.

3. Proving Negligence: Construction Standards and Your Exposure to Injury Lawsuits

If you find yourself in court trying to sue a contractor, you must prove that their work failed to satisfy reasonable construction standards.

A contractor holding themselves out as having special trade skills owes a duty to exercise the same degree of skill and care that other reasonable contractors in the community would exercise. Furthermore, evidence of general industry customs—such as using joist hangers rather than improper toe-nailing—serves as key proof of reasonable conduct. Under Trimarco v. Klein, 56 N.Y.2d 98 (1982), failure to abide by generally accepted industry safety practices constitutes evidence of negligence.

Your Exposure as a Homeowner if Someone Gets Hurt: Beyond property damage, bad craftsmanship creates severe legal exposure for you as a property owner. Under New York premises liability law, a landowner has a duty to keep their property in a reasonably safe condition. If a sinking deck board or missing joist support causes a structural collapse that injures a guest, neighbor, or delivery worker, you as the homeowner can be sued directly.

If you noticed sinking boards or dangerous defects and failed to repair or warn visitors, a court can find you had actual or constructive notice of the unsafe condition. Walsh v Super Value, Inc., 76 AD38d 371, 904 NYS2d 121 (2d Dept 2010). But even if you did not know specifically that joist hangers were missing, you still face liability for hiring an unqualified or unlicensed contractor. Did you check if the contractor was licensed before hiring them? Did you confirm whether Department of Buildings (DOB) permits were required and properly pulled? Homeowners may not know how to build a deck themselves, but they have a non-delegable obligation to maintain safe premises—and cutting corners on cheap, unpermitted labor can leave you personally responsible when structural failures cause life-altering injuries.

4. Measurable Damages: Costs to Repair and Permits

When bringing a defective construction claim for property damage, your measure of recovery is not what you paid the first contractor, but what it costs to make the project safe and complete.

• Cost to Repair: Your primary legal damages consist of the fair and reasonable cost paid to the second contractor to repair the defective framing, reinstall joist hangers, secure proper fasteners, and level the sinking deck.
• Building Permits & Unpermitted Work Costs: If the original contractor failed to obtain required building permits from the Department of Buildings (DOB), any additional fees, corrective architectural filings, or penalty permit fees required to bring the deck into full DOB compliance are recoverable items of damage.

5. Collection of Judgment

One of the most disappointing parts about civil cases is the collection of a judgment. If you truly find yourself in court suing a contractor, odds are the person was not licensed and probably not insured. Furthermore, there is a probability that the contractor you hired was not a person, but a corporation which may have no assets to attach. So if you had a contract with ABC Home Improvement and not John Doe, you have to try and collect a judgment against ABC Home Improvement. The chances of you collecting this judgment are slim.
