Home Improvement Contracts in New York: Legal Requirements

Why Written Contracts Matter

A written contract protects both the homeowner and the contractor by setting clear expectations and preventing disputes. It states what work will be done, what will not be done, the total cost, payment terms, timeline, and dispute resolution methods. When disputes arise (and they do), the written contract is the evidence of what was agreed to. Handshake deals and informal agreements lead to disputes because people remember differently.

Under New York law, home improvement contracts must be written. Oral agreements for home improvement work are not enforceable in certain circumstances, leaving the contractor unable to collect payment and the homeowner without clear remedies. A good written contract prevents costly litigation by addressing issues upfront. Contractors should insist on written contracts to protect their right to payment; homeowners should insist on written contracts to protect themselves from unexpected costs and unclear scope.

Required Contract Terms Under NY General Business Law

The contract must include: a description of the work to be performed (specific enough that both parties know what is included), the total contract price and how it will be paid, the payment schedule (when and how much is due at each stage), the contractor's name and license number, the contractor's address, phone, and email, the homeowner's name and address, the property address, the start and expected completion date, and what happens if the contractor abandons the work or fails to complete.

The contract must also include specific notices in at least 10-point type: the homeowner's right to cancel within three business days of signing (a mandatory cooling-off period), the contractor's license number and how to verify it with the county, the contractor's liability and workers' compensation insurance information, and a statement that the homeowner should not make checks payable to subcontractors only to the contractor. These notices protect homeowners by ensuring they understand their rights and the contractor's credentials.

Contractor Licensing in Suffolk County

Home improvement contractors working on residential property in Suffolk County must be licensed through the county's consumer affairs office. Licensing requires application, background check, proof of insurance, and bonding. An unlicensed contractor cannot sue for payment for residential work in Suffolk County and cannot file or enforce a mechanic's lien. This is a strict rule with no exceptions. If a contractor says they do not need a license or that licensing is optional, they are wrong and trying to work around the law.

Before hiring any contractor for residential work, verify their license status with the Suffolk County consumer affairs office. If they are not licensed, do not hire them. An unlicensed contractor performing substantial work has almost no remedy if not paid, while a homeowner who pays an unlicensed contractor has limited recourse if the work is defective. This requirement protects homeowners, but it also means homeowners must verify licensing before contracting.

Deposit and Payment Terms

New York law restricts how deposits can be handled. Generally, the contractor cannot require a deposit exceeding 10 percent of the contract price or $1,000, whichever is less. That deposit must be held in a separate trust account or covered by a surety bond, not commingled with the contractor's business funds. The deposit is held to secure the contractor's performance, not to be spent on other jobs or expenses. This protection ensures your deposit is safe until work begins.

Payment terms should be tied to completion of milestones: an initial deposit when the contract is signed, progress payments as work is completed and inspected, and a final payment after final inspection and walkthrough. Avoid paying in advance for work not yet done. Do not pay the full contract price until the work is complete, inspected, and you are satisfied. Retaining 10 percent until final completion gives you leverage to ensure the contractor finishes properly.

Change Orders and Scope Creep

The contract should clearly distinguish between the included scope of work and optional "extras" or "change orders." If the homeowner requests additional work beyond the original contract (more square footage, upgraded materials, additional rooms), that change must be documented in a written change order signed by both parties. The change order should state the additional work, the additional cost, and how it affects the timeline. This prevents disputes over whether extra work was included in the original price or is an add-on.

Contractors should never perform extra work without a written change order and agreement on the price. Homeowners should never agree to extra work without understanding the additional cost and timeline impact. Changes are normal in construction, but they must be documented in writing to avoid disputes later. A clear change order process prevents one party from claiming the other party owes money or performance for unexpected extras.
