Comprehensive guide to pursuing construction defect claims against contractors in New York. Covers New York Lien Law, NYC Department of Buildings requirements, Home Improvement Contractor licensing, N.Y. Gen. Bus. Law Section 349 consumer protection, and sample demand language.
New York Construction Defect Claims
Construction defects can range from cosmetic issues to serious structural failures that threaten the safety and value of your home. New York law provides multiple avenues for homeowners to recover damages from contractors who perform defective work, abandon projects, or fail to meet contract specifications.
New York Construction Law Framework
New York's construction defect framework involves several overlapping laws:
Contract law: Breach of contract claims based on failure to perform as agreed
Negligence: Failure to perform work with reasonable skill and care
New York Lien Law: Trust fund requirements, lien rights, and Article 3-A protections
N.Y. Gen. Bus. Law Section 349: Consumer protection against deceptive practices
NYC Admin Code: Home Improvement Contractor licensing (NYC only)
NYC Building Code: Permit requirements and code compliance
In New York City, contractors performing home improvement work valued over $200 must be licensed by the NYC Department of Consumer and Worker Protection (DCWP) under NYC Admin Code Section 20-386.
Contractors must have HIC license and display license number on contracts and advertisements
Working without license is a misdemeanor; contractor cannot sue for payment on unlicensed work
Verify license status at: nyc.gov/consumers or call 311
File complaints with DCWP for unlicensed work or contract violations
Statute of Limitations
Critical Deadlines
Breach of contract: 6 years from the breach under CPLR Section 213
Negligence: 3 years from when damage occurred under CPLR Section 214
GBL Section 349 claims: 3 years from the deceptive act
Statute of repose: CPLR Section 214-d limits claims to 10 years from substantial completion for construction projects
Discovery rule: For latent defects, the limitations period may run from discovery, but subject to the 10-year repose period
Do not delay. Evidence deteriorates, contractors go out of business, and deadlines pass.
Legal Theories for Construction Defect Claims
Construction defect claims in New York can proceed under multiple legal theories. Choosing the right theory affects your available damages, burden of proof, and strategic options.
1. Breach of Contract
The primary claim for construction defects is breach of contract. You must prove:
Valid contract: Written or oral agreement (written strongly preferred)
Performance by you: You paid or were ready to pay as agreed
Breach by contractor: Work failed to meet contract specifications, building codes, or industry standards
Damages: The defective work caused you financial harm
If the contract does not specify a standard, New York law implies a duty to perform work in a "workmanlike manner" consistent with industry standards.
2. Negligence
Contractors owe a duty of care to perform work with reasonable skill. Negligence claims may provide access to damages not available under contract:
Duty: Contractor owed duty to perform with skill and care
Breach: Work fell below professional standards
Causation: Negligent work caused the defect
Damages: You suffered harm as a result
3. N.Y. Gen. Bus. Law Section 349 (Consumer Protection)
Section 349 prohibits deceptive acts and practices in the conduct of any business. This powerful statute may apply if the contractor:
Made false representations about qualifications, licensing, or experience
Misrepresented the quality of materials to be used
Falsely claimed permits were obtained when they were not
Used bait-and-switch tactics on pricing or scope
Provided misleading estimates or concealed known defects
Advantages of Section 349: You can recover actual damages plus reasonable attorney fees. For willful violations, you may recover treble damages up to $1,000.
4. New York Lien Law: Trust Fund Provisions
Article 3-A of the New York Lien Law creates powerful protections for both homeowners and subcontractors:
Section 70: All payments to contractors are held in trust for subcontractors and suppliers
Section 71: Defines what constitutes trust assets and who are trust beneficiaries
Section 79-a: Diversion of trust funds is larceny (criminal offense)
If your contractor took your money but failed to pay subcontractors (leaving you with liens), this may constitute criminal diversion of trust funds.
NYC Building Code Violations
🏗
Permit Requirements
Most construction work in NYC requires permits from the Department of Buildings (DOB). Work without permits violates the Building Code.
📋
Licensed Professionals
Certain work requires a licensed architect or engineer to file plans. Electrical work requires licensed electricians. Plumbing requires licensed plumbers.
⚠
DOB Violations
Unpermitted work can result in violations, stop-work orders, and fines. The homeowner (not contractor) is often named on violations.
📝
Negligence Per Se
Violation of Building Code may establish negligence as a matter of law, eliminating the need to prove the contractor failed to meet the standard of care.
How to Search DOB Records
NYC Department of Buildings maintains public records of permits, violations, and complaints. Search at:
Buildings Information System (BIS): a836-acris.nyc.gov/bblsearch/
DOB NOW: nyc.gov/dobnow - For newer filings
Search by address to find all permits filed, open violations, complaints, and licensed professionals associated with the property
Evidence Gathering for Construction Defect Claims
Thorough documentation is essential for construction defect claims. Contractors will dispute the extent of defects, argue you approved the work, or blame other parties. Your evidence must clearly establish what was promised, what was delivered, and the cost to fix it.
Contract Documentation
📋
Written Contract
The original contract showing scope of work, specifications, timeline, and price. Include all pages and attachments.
📄
Change Orders
All written change orders modifying the original scope, price, or timeline. Note any verbal changes you discussed.
💰
Payment Records
Canceled checks, bank statements, credit card receipts, wire confirmations showing all payments made.
💬
Communications
All emails, texts, and letters with the contractor. Include communications where contractor acknowledged problems or promised repairs.
Defect Documentation
📷
Photographs and Video
Comprehensive documentation of all defects. Take photos from multiple angles, include context shots, and date/timestamp everything.
🔎
Expert Inspection Report
Hire a licensed engineer, architect, or home inspector to document defects and their causes. Expert reports carry significant weight.
💰
Repair Estimates
Get at least 2-3 written estimates from licensed contractors to repair the defective work. These establish your damages.
⚠
Code Violations
Search NYC DOB records for any violations, complaints, or stop-work orders at your property.

All communications with you and subcontractors
Invoices from material suppliers
Subcontractor agreements
Permits and inspection records
Photos taken during construction
Time records and project logs
Destruction of evidence after receiving this demand may result in spoliation sanctions.
Damages in New York Construction Defect Cases
New York allows recovery of multiple categories of damages for construction defects. The measure of damages depends on whether the defect is repairable and the nature of your claim.
Cost of Repair
The primary measure of damages is the reasonable cost to repair the defective work to the standard specified in the contract or required by code. This includes:
Labor costs for remedial work
Materials for repairs
Demolition of defective work
Permits and inspections
Professional fees (engineering, architecture)
Diminution in Value
If repair is impossible or economically impractical, you may recover the reduction in your property's fair market value caused by the defects. This requires appraisal evidence comparing:
Value if work had been done properly
Actual value with defective work
Consequential Damages
Temporary housing: If defects make home uninhabitable during repairs
Storage costs: Moving and storing belongings during repairs
Damaged property: Personal belongings damaged by defects (e.g., water damage to furniture)
Lost rental income: If you planned to rent the property
Additional utility costs: From inefficient HVAC or insulation failures
Special Damages Under GBL Section 349
Consumer Protection Recovery
If you establish a claim under General Business Law Section 349:
Actual damages: All out-of-pocket losses
Reasonable attorney fees: Recoverable even if you win a modest amount
Treble damages: Up to three times actual damages, capped at $1,000, if the violation was willful or knowing
The attorney fee provision makes Section 349 claims viable even for smaller defect cases.

Not allowing defects to worsen when you could prevent it
Getting competitive estimates rather than paying unreasonable repair prices
Document all mitigation efforts. You can recover reasonable mitigation costs as part of your damages.

RE: DEMAND FOR REPAIR OF CONSTRUCTION DEFECTS
Property: [Your Address]
Contract Date: [Date]
[NYC HIC License #: [Number] - if applicable]
Dear [Contractor Name]:
I write regarding the seriously defective construction work you performed at my property located at [Address], New York pursuant to our contract dated [Date]. This letter constitutes formal notice of defects and demand for cure.
CONTRACT AND PERFORMANCE
On [Date], we entered into a written contract for [describe scope - e.g., "renovation of the master bathroom, including new tile, fixtures, plumbing, and waterproofing"]. The contract price was $[Amount], of which I have paid $[Amount paid].
The work was represented as completed on [Date]. However, I have discovered numerous serious defects in the work that violate our contract specifications, applicable building codes, and industry standards for workmanlike performance.
SPECIFIC DEFECTS
The following defects have been identified:
1. [Describe defect #1 in detail - e.g., "Water intrusion through the shower surround. Within two weeks of completion, water began leaking through the ceiling of the room below the bathroom. Investigation revealed improper waterproofing membrane installation and failure to properly seal tile joints."]
2. [Describe defect #2 - e.g., "Uneven tile installation. Floor tiles are visibly uneven with lippage exceeding industry standards (ANSI A108.02), creating a tripping hazard and aesthetic defect."]
3. [Describe defect #3 - e.g., "Plumbing code violations. The drain trap is improperly configured, creating potential for sewer gas entry. This violates NYC Plumbing Code Section [X]."]
[Continue for all defects]
These defects have been documented by [describe documentation - licensed engineer, home inspector, etc.] in a report dated [Date], a copy of which is enclosed.
[If unpermitted work]: Furthermore, this work was performed without required NYC Department of Buildings permits in violation of the NYC Building Code. No permit was filed for [describe work requiring permit]. This unpermitted work exposes me to DOB violations and fines, and must be properly permitted as part of any repair.
[If unlicensed - NYC only]: Additionally, my records indicate you [performed this work without a valid NYC Home Improvement Contractor license / your HIC license was suspended at the time of the work] in violation of NYC Admin Code Section 20-386. Under New York law, you cannot enforce a contract for unlicensed home improvement work, and you are liable for all damages I have suffered.
LIABILITY UNDER NEW YORK LAW
Your work breaches our contract and constitutes negligence under New York law. You had a duty to perform this work in a workmanlike manner consistent with the contract specifications, applicable building codes, and industry standards. You breached that duty.
[If GBL 349 applies]: Additionally, your [describe deceptive conduct - e.g., "representation that you held all required licenses and would obtain necessary permits, when in fact you did not"] constitutes a deceptive business practice in violation of New York General Business Law Section 349.
DAMAGES
I have incurred the following damages:
- Cost to repair defects (per estimates): $[Amount]
- Damage to property from leaks: $[Amount]
- Engineering/inspection costs: $[Amount]
- [Other consequential damages]: $[Amount]
TOTAL DAMAGES: $[Amount]
DEMAND
Pursuant to our contract and New York law, I demand that you:
OPTION 1 - REPAIR: Complete all necessary repairs within 30 days using licensed subcontractors, at your expense, with all work subject to my inspection and approval, and obtain all required permits; OR
OPTION 2 - PAYMENT: Pay the total damages of $[Amount] within 15 days so I may hire a competent contractor to properly complete the work.
If I do not receive a satisfactory response by [Date - 15 days], I will:
- File a complaint with NYC Department of Consumer and Worker Protection
- Report unpermitted work to NYC Department of Buildings
- Initiate legal action in [Supreme Court / Small Claims Court] seeking all damages plus attorney fees under GBL Section 349
- Report potential Lien Law violations to appropriate authorities
The 6-year statute of limitations for contract claims (CPLR 213) and 3-year limitation for negligence claims (CPLR 214) preserve my right to bring legal action.
This letter is written without prejudice to any additional claims or remedies I may have.
Sincerely,
[Your Signature]

Project: [Address]
Dear [Contractor]:
I write to demand compensation for your deceptive business practices in connection with the construction work at my property.
DECEPTIVE CONDUCT
Prior to signing our contract, you represented that:

These representations were false. In fact:

- [Describe truth]
I relied on these representations in deciding to hire you and in paying the contract price of $[Amount].
GBL SECTION 349 CLAIM
Your conduct constitutes deceptive acts and practices in violation of New York General Business Law Section 349. Under this statute, I am entitled to recover:
1. Actual damages caused by your deceptive practices
2. Reasonable attorney fees
3. Treble damages up to $1,000 if your conduct was willful
DEMAND
I demand payment of $[Amount] representing:
