Good News for New York Contractors

New York does not require a pre-lien preliminary notice for most contractors. The Lien Law is procedurally complex — verify with an attorney. You still must file the lien within the deadline and in the correct recording office.

Commercial vs Residential

Does the Property Type Change Your Deadline?

Residential single-family dwellings have a shorter 4-month deadline. Commercial and multi-unit residential projects get 8 months. Verify the property type before relying on a deadline.

Common Mistakes

What Contractors Get Wrong in New York

1
Using the 8-month commercial deadline for single-family residential — those get only 4 months
2
Failing to serve the owner within 5 days of filing
3
Not enforcing the lien — New York requires enforcement within 1 year of filing (or filing an extension)
