Home-Improvement Contracts Belong in Writing

A written contract, payment schedule, and permit check can prevent many home-improvement disputes.

Published June 23, 2026 · Last verified June 23, 2026

A home-improvement job should not rest on a handshake and a vague invoice. State law requires a contractor to provide a written contract for home-improvement work. The contract should include a timeline, payment schedule, and specific project details, including materials where that matters. Verbal changes should be added to the written contract, because the contractor is bound by what is in the contract.

Before work starts, check permits with the local building department and check licensing where local law requires it. The Attorney General identifies New York City, Suffolk, Nassau, Westchester, Putnam, and Rockland as places where home-improvement contractors must be licensed. Separate what this record proves from the next permit, tax, title, inspection, or court question.

The clean move in New York is to turn the question into one named record. From New York State Attorney General: Hiring a Home-Improvement Contractor, save the exact home improvement or contracts, the date, and the number or address that would let an office find the same thing again. Write New York State Attorney General beside the note, especially when a later question turns on money, title, access, a permit, a license, or a deadline. New York home improvement or contracts follow-up goes better when the next call starts with the exact words from the form or notice.
