3 deadlines NoticeGuard models for New York: what each one counts from, the statute it was read from, and the statute text.
Information, not legal advice. This app reports what the statute says and cites the section it read. It is not legal advice, it does not file anything for you, and it does not tell you what to do.
Verify with the statute or an attorney. Statutes change, and courts reinterpret them. Every deadline in this app comes from a statute read on the date shown next to its citation - that snapshot can go out of date. Missing a mechanics lien deadline can extinguish your claim permanently, so confirm any deadline you are relying on with an attorney licensed in that state before you act on it.
Data verified: statute text retrieved 2026-09-21 (each citation below carries its own date). Rule data from the NoticeGuard app, source commit 22f9300.
Filed with the county clerk where the property is located, counted from the last item of work performed or materials furnished. Applies unless the property is a single-family dwelling (see the shorter sibling rule).
What it counts from. 240 days after last furnishing (last day on site).
Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service (when you do not tick "This property is a single-family dwelling").
New York Lien Law § 10 (1) Official source · statute text retrieved 2026-09-21
“Notice of lien may be filed at any time during the progress of the work and the furnishing of the materials, or, within eight months after the completion of the contract, or the final performance of the work, or the final furnishing of the materials, dating from the last item of work performed or materials furnished; provided, however, that where the improvement is related to real property improved or to be improved with a single family dwelling, the notice of lien may be filed at any time during the progress of the work and the furnishing of the materials, or, within four months after the completion of the contract, or the final performance of the work, or the final furnishing of the materials, dating from the last item of work performed or materials furnished...”
If the date is missed (the statute's own terms). The statute states the notice of lien "may be filed... within eight months" of this anchor - a lien not filed within this period is not filed in time to be valid.
Also stated next to this deadline.
Approximated as 240 calendar days (8 months × 30), not a literal calendar-month count - the same kind of approximation Florida's "1 year" (365 days) and Idaho's/Arizona's "6 months" (180 days) already make elsewhere in this app.
No role-based exemption: § 3 gives identical lien rights to a contractor, subcontractor, laborer, or materialman, and § 10 runs the same clock for all of them - unlike Florida's privity exemption for an original contractor.
A lien may also be filed earlier, at any time during the progress of the work - this rule shows only the outer deadline, not the earliest a lien could be filed.
File notice of lien (single-family dwelling)
Filed with the county clerk where the property is located, counted from the last item of work performed or materials furnished - the shorter period that applies specifically to a single-family dwelling.
What it counts from. 120 days after last furnishing (last day on site).
Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service (when you tick "This property is a single-family dwelling").
New York Lien Law § 10 (1) Official source · statute text retrieved 2026-09-21
“...provided, however, that where the improvement is related to real property improved or to be improved with a single family dwelling, the notice of lien may be filed at any time during the progress of the work and the furnishing of the materials, or, within four months after the completion of the contract, or the final performance of the work, or the final furnishing of the materials, dating from the last item of work performed or materials furnished...”
If the date is missed (the statute's own terms). The statute states the notice of lien "may be filed... within four months" of this anchor for a single-family dwelling - a lien not filed within this shorter period is not filed in time to be valid.
Also stated next to this deadline.
Approximated as 120 calendar days (4 months × 30), the same approximation style used throughout this app.
§ 10 itself carves back OUT of this shorter period: a single-family dwelling that is part of a subdivision owned by a "developer" (as § 10 defines that term) for purposes other than a personal residence does not qualify - the ordinary 8-month rule applies instead. This app does not detect that case; see this state's `limitations`.
§ 10's own text says "single family dwelling," not "one- or two-family" - this app does not extend the shorter period to a two-family property without a confirmed statutory or case-law basis. See `limitations`.
Commence foreclosure, file an extension, or obtain a court order to keep the lien alive
Counted from the date the notice of lien was filed. Before this date, the lienor must either commence a foreclosure action and file a notice of pendency, file a self-executing extension with the county clerk (not available for a single-family dwelling), or - for a single-family dwelling - obtain a court order continuing the lien.
What it counts from. 365 days after notice of construction lien recorded.
Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service.
New York Lien Law § 17 (first paragraph, "Duration of lien") Official source · statute text retrieved 2026-09-21
“No lien specified in this article shall be a lien for a longer period than one year after the notice of lien has been filed, unless within that time an action is commenced to foreclose the lien, and a notice of the pendency of such action... is filed with the county clerk of the county in which the notice of lien is filed... or unless an extension to such lien, except for a lien on real property improved or to be improved with a single family dwelling, is filed with the county clerk of the county in which the notice of lien is filed within one year from the filing of the original notice of lien, continuing such lien and such lien shall be redocketed as of the date of filing such extension.”
If the date is missed (the statute's own terms). The statute states the lien "shall not be a lien for a longer period than one year" from filing unless one of the listed actions happens within that year - after it, and with none of those actions taken, the lien is no longer a lien on the property.
Also stated next to this deadline.
Approximated as 365 calendar days (1 year × 365), the same approximation style used throughout this app. A calendar year is 365 or 366 days, so this date always lands on or before the statutory one - never after it.
A single-family dwelling lien cannot use the self-filed clerk extension at all - its only path past the one-year date is a court order, and the statute caps that route at "two successive years" of renewal. This app does not model the renewal path itself, only the first one-year deadline - see `limitations`.
A clerk-filed extension (for a non-single-family property) appears repeatable each year, since each extension "redockets" the lien as of its own filing date - again, this app shows only the first deadline, not how many further renewals remain.
Weekend and holiday rollover
NoticeGuard does not model a weekend or holiday extension for New York. The dates above are the plain count from the date you enter. Check whether a Saturday, Sunday or holiday changes your date.
What this rule set does not cover
The retainage-only lien (§ 10: "within ninety days after the date the retainage was due to be released") and the real estate broker commission lien (a different anchor - lease execution by both parties - and a different role this app does not model) are both real, separate branches of § 10 that are NOT modeled here. Only the ordinary "last item of work or materials" anchor is used.
§ 10's shorter deadline is modeled for "single family dwelling," exactly the statute's own words. New York practice commonly extends the same shorter treatment to two-family owner-occupied dwellings, but § 10's own text says "single family dwelling" only - this app does not encode a "two-family" branch without a confirmed primary-source or case-law basis for it, and the toggle should not be assumed to cover a two-family property.
§ 10's single-family carve-out has its own carve-back: a "single family dwelling" that is part of a subdivision owned by a "developer" (as defined in § 10) for purposes other than a personal residence is NOT treated as a single-family dwelling for this section, meaning the ordinary 8-month period applies instead. This app does not detect that case automatically - a user building spec homes under a common plan should not assume the 4-month toggle applies to them just because the structure is a single-family house; read § 10 itself.
§ 17's "keep the lien alive" deadline is modeled only as the base one-year-from-filing date. What actually happens at that date is a choice (commence foreclosure + file a notice of pendency; file a clerk extension, unavailable for single-family dwellings; or, for a single-family dwelling, obtain a court order, capped at two successive one-year renewals) - this app shows only the date by which one of those must happen, not which option is available to which property type or how many further renewals remain. Read § 17 itself for the mechanics beyond the first deadline.
Weekend/holiday rollover is NOT modeled - deliberately, not by oversight. General Construction Law § 25-a is a general "any period of time... required to be done" rollover, and its Reviser's note treats it as broadly applicable, but no Lien Law-specific citation confirming its application to a § 10 or § 17 deadline was found. Rather than assume a general statute of construction reaches this specific chapter the way Utah's URCP 6 and Florida's § 713.011 explicitly say they do for their own chapters, New York dates are shown raw and un-extended - the same honest gap as Idaho's and Arizona's missing rollover.
Only §§ 2, 3, 9, 10, 17, 21, and 73 have been read (spot-checking § 21 and § 73 only to confirm they are out of scope - public improvements and lender trust-fund notices, respectively). The rest of the Lien Law, including Article 3-A's trust-fund diversion provisions generally and any residential-specific home-improvement-contract requirements under General Business Law, is not incorporated.
This app generates a document for the notice of lien itself (§ 9's required-content list) - not for the notice of pendency, a clerk-filed extension, or a foreclosure action, none of which is a statutory form; those are court filings governed by the CPLR and local practice.
NoticeGuard is an app that turns a job's dates into a countdown for each statutory step, shows the statute text each date was read from, exports a calendar file (.ics) and sends reminders 14, 7 and 1 day before each deadline. It tracks and reminds; it does not file anything for you.
