What is the deadline to file a mechanics lien in New York?
Last reviewed July 5, 2026
In New York, a mechanics lien must be filed within 8 months after the last work was performed or materials were supplied. If the project is residential and the property owner files a notice of completion, the deadline shortens to 4 months.
Key points
- File within 8 months for general projects
- 4-month deadline for residential projects after notice of completion
- Lien claims must be filed in the county where the property is located
Make sure to track when the last work was done or materials were supplied to hit those deadlines. If you're on a residential job, keep an eye out for any notice of completion from the owner, as that will change your timeline. Always check the specific county requirements, as they can vary.
