1. What New York Requires in a Home Improvement Contract
New York regulates residential home improvement more tightly than an ordinary business contract. General Business Law Article 36-A sets the required terms for a residential home improvement contract, while commercial buildouts fall outside it and run on common law and the Lien Law.
Required Terms and the License Rule
Section 771 calls for a written, signed contract describing the work, materials, approximate dates, total price, and a progress-payment schedule. In New York City, a residential home improvement contractor also needs a DCWP license, and an unlicensed one generally cannot recover payment at all. Confirm the license before work begins, not after a dispute.
Deposits and Escrow Protection
Under Section 771-a, money a homeowner pays before the work is substantially complete generally must sit in escrow, unless the contractor is bonded or the contract meets specific conditions. This keeps a deposit from vanishing if the job stalls. The construction contract should say how and where funds are held.
2. Lien Rights: Your Leverage and Your Risk
The Lien Law gives a remodeling deal its real leverage. It protects unpaid contractors and, when ignored, exposes owners to paying twice.
| Party | Main protection | How to secure it |
|---|---|---|
| Contractor | Mechanic's lien for unpaid work | File the notice of lien on time and keep records |
| Owner | Avoiding double payment | Collect lien waivers and a sworn subcontractor list before final pay |
| Owner (tenant's work) | Keeping a tenant's project off your title | Address consent and lien risk in the lease |

The Contractor'S Mechanic'S Lien
An unpaid contractor or subcontractor can file a mechanic's lien against the improved property under the Lien Law. The lien must be filed on time and served on the owner to stay valid. A valid lien can force payment or lead to foreclosure on the property.
How Owners Protect Themselves
Before releasing final payment, an owner should collect lien waivers and a sworn statement listing every subcontractor and supplier. Funds received for the project are trust assets under Lien Law Article 3-A, so diverting them can be a crime. When work is done for a tenant, whether a lien can reach the owner's interest turns on the owner's consent under the Lien Law and the surrounding facts, so the lease should address it.
3. Payment, Retainage, and Substantial Completion
Payment terms decide who has the upper hand while the work finishes. New York also limits how much an owner can hold back on covered projects.
Progress Payments and the Retainage Cap
Most contracts tie progress payments to completed milestones, with a portion held back as retainage. Where New York's Prompt Payment Act applies to a private construction contract, retainage is capped at 5 percent, though small one- and two-family jobs can fall outside the Act. State when each payment is due and what triggers release.
Substantial Completion and the Punch List
Fights often turn on whether the work is substantially complete or merely cosmetically unfinished. Define substantial completion, the punch-list process, and the deadline for final payment once it is reached. Clear language here usually decides the retainage dispute.
4. Change Orders and Unforeseen Conditions
Change orders cause more remodeling disputes than any other term, especially when hidden damage or code issues surface mid-project. The contract should require any change to scope, price, or schedule in writing, and a no-oral-modification clause helps that hold up under New York law.
- The work being added or removed, and why.
- The change in price and how it is calculated.
- The effect on the schedule and completion date.
5. Frequently Asked Questions
Can an unlicensed contractor sue for payment in New York City?
For residential home improvement work, generally no. New York City bars an unlicensed contractor from recovering payment, and courts often deny recovery even for work already finished. The lack of a required license can also affect the contractor's ability to enforce a mechanic's lien or other payment remedies.
How long do I have to file a mechanic's lien in New York?
For a single-family dwelling, you generally must file within four months after the work is finished. For other property, the window is usually eight months. Missing the deadline typically forfeits the lien, even when the debt is real.
Can I withhold final payment if the remodeling work is defective?
Whether you may withhold part or all of the balance depends on the contract, the nature of the defects, and whether the job is substantially complete. As a rule, holding back an amount tied to incomplete or defective items and the retainage is safer than withholding everything. The contract's definition of substantial completion and its punch-list terms guide how much you can keep.
