1. Which Construction Claims Require an Owner-Side Review?
Owners may have claims involving unauthorized charges, unfinished work, defects, or delays. The legal issue is what the contractor promised, whether those obligations were breached, and what loss resulted.
Disputed Changes and Project Delays
An invoice does not prove the owner authorized extra work. Compare the original scope, change orders, emails, and payment records. A missing signature may support a defense, but the parties' conduct can also matter. For delays, review schedules and site records to identify responsibility. Contractual notice requirements and damage limitations may affect recovery.
Defective Work and Incomplete Construction
Owners may recover repair costs or other proven losses when work breaches contractual requirements. Photos, inspections, and replacement estimates help establish the problem and its cost. Different records answer different questions.
| Dispute | Key Evidence | Legal Question |
|---|---|---|
| Extra charges | Change orders, invoices | Was the work authorized? |
| Delay | Schedules, site logs | Who caused the delay? |
| Defects | Photos, inspections | What breached the contract? |
| Unfinished work | Reports, estimates | What remains incomplete? |

2. When Do Contract and Licensing Rules Affect Payment?
Residential and commercial projects face different requirements. Project classification and contractor licensing may affect whether payment claims are enforceable.
Home-Improvement Contracts and Licensing Defenses
New York General Business Law §§770–771 require covered home-improvement contracts exceeding $500 to be written and signed, with specified terms and notices. The rules cover certain custom homes but generally exclude ordinary new-home construction. Nassau County Administrative Code §21-11.2 requires licenses for covered home-improvement businesses. In Nationwide HVAC Supply Corp. V. Mosby (2025), the Appellate Division rejected an unlicensed contractor's contract and lien foreclosure claims. A licensed subcontractor did not cure the defect. Owners should verify licensing during the work. The Nassau County Department of Consumer Affairs handles complaints, but its process does not replace a damages lawsuit.
Permits, Inspections, and Local Requirements
The responsible town, city, or village generally issues building permits. Owners should check approved plans, inspection findings, and stop-work notices. A contractor's license does not establish permit compliance. If an inspection fails, the contract may determine who pays for corrections. The California construction attorney guide addresses disputes governed by different state rules.
3. How Can Owners Challenge a Mechanic's Lien?
A lien can delay a sale or refinancing without proving the debt. Filing records, unpaid balances, and contractor relationships help determine its enforceability.
Verify Filing and Service Requirements
Under New York Lien Law §10, private-project liens generally may be filed during construction or within eight months after qualifying work or materials were last furnished. The usual period for single-family dwelling improvements is four months, subject to exceptions. Retainage claims have a separate 90-day provision after retainage becomes due for release. Lien Law §11 generally requires owner service within five days before or 30 days after filing. Proof of service must be filed within 35 days after filing, or the notice terminates as a lien. Owners can check these records with the Nassau County Clerk.
Examine the Amount and Discharge Options
Under Lien Law §4, subcontractor and supplier liens generally depend on earned, unpaid contract funds, subject to exceptions. Section 38 allows owners to demand a verified breakdown. An inadequate response after five days may support a court petition, not automatic cancellation. Section 17 generally limits a lien's initial duration to one year unless preserved or extended. Extending a single-family dwelling lien requires a court order. Section 19 permits discharge through specified methods, including a qualifying undertaking generally equal to 110% of the lien amount. Discharge does not settle the debt. A mechanic's lien review may be needed before closing.
4. What Should Owners Do before Settlement or Litigation?
Withholding payment or terminating a contract without following required notices may expose an owner to a counterclaim. Review available remedies and costs before acting.
Avoid Notice and Evidence Mistakes
Several mistakes can weaken a claim:
- Withholding payment without checking notice and cure terms.
- Repairing defects before documenting them, unless safety requires immediate action.
- Signing a final release without reviewing subcontractor claims.
- Terminating work without preserving communications and completion records.
If insurance may apply, check coverage and reporting requirements. Defective workmanship alone does not automatically establish coverage.
Select the Appropriate Dispute Procedure
Settlement may address unpaid amounts, repairs, and lien releases together. Some contracts require mediation or arbitration before litigation. Other disputes may proceed in Nassau County Supreme Court. Its Commercial Division generally requires a qualifying claim meeting the $200,000 threshold, subject to exceptions. A construction litigation assessment can compare potential recovery with expert expenses, legal costs, and settlement options.
5. Frequently Asked Questions
How Much Does a Construction Attorney Cost in Nassau County?
Fees depend on the services and engagement agreement. Attorneys may charge hourly rates, fixed fees, or retainers. Litigation can add filing, deposition, and expert expenses. Request written terms explaining the scope, billing method, and additional costs.
Can I Sue a Construction Company for Excessive Noise?
Possibly. A private nuisance claim may arise when noise substantially and unreasonably interferes with property use. Ordinary inconvenience is insufficient. Record its frequency, duration, and impact, and check local noise restrictions. Nuisance claims are distinct from construction contract disputes.
6. Request a Construction Dispute Case Review
Our firm's attorneys can examine contracts, payments, licensing, inspections, and lien filings to identify possible claims, defenses, deadlines, and resolution options.
