New York lien deadlines for contractors
Updated · Checked against primary sources
The short answer
In New York, file a notice of lien with the county clerk within 8 months after completing the contract or your final work or materials, or 4 months for a single family dwelling. Serve the owner within 30 days after filing and file proof of service within 35 days. The lien lasts one year unless you foreclose or extend it.
The deadlines
| Step | Rule |
|---|---|
| Preliminary notice: who | None. New York does not require a preliminary notice on private improvements. |
| Preliminary notice: when | Not applicable. |
| File or register the lien | File the notice of lien in the county clerk's office any time during the work or within 8 months after completion of the contract, the final performance of work or the final furnishing of materials; within 4 months for real property improved or to be improved with a single family dwelling; and within 90 days after retainage was due for a retainage lien (N.Y. Lien Law 10). Serve a copy on the owner within 5 days before or 30 days after filing, and file proof of service with the county clerk within 35 days after filing or the lien terminates (Lien Law 11). |
| Enforce or perfect it | The lien expires one year after filing unless, within that year, a foreclosure action is commenced and a notice of pendency is filed, or (except for single family dwellings) a one-year extension is filed with the county clerk. Further continuance requires a court order (Lien Law 17). |
| Residential jobs | Single family dwelling: 4-month filing window instead of 8 months, and the lien can be extended only by court order, not by filing an extension (Lien Law 10, 17). Dwellings in a developer's filed subdivision are not treated as single family dwellings for the filing period. |
Other notices and rules
- Until the notice is served, an owner without knowledge of the lien is protected in good faith payments to the contractor (Lien Law 11).

Where Pavado comes in
How Pavado builds a CRM around your jobs
Lien rights are usually lost to a calendar, not a court. We build CRMs that start each job's notice and lien clocks from its real start and completion dates and remind you before every deadline, so the rights you earned by doing the work are still there when a customer stops paying.
Instead of bending your shop around someone else's software, we build the system around how your jobs actually move, and connect it to what you already use.
- Your pipeline, your stages. From first call to paid invoice, set up the way your team already works.
- Automations for the busywork. Follow-ups, reminders and handoffs that happen without anyone remembering.
- One record per customer. Calls, quotes, jobs, photos and invoices in one place instead of five apps.
- Connected to your stack. QuickBooks or Xero, Gmail or Outlook, payments and e-sign, plus thousands more through Zapier and an API.
