Who the deadlines apply to
Vermont's mechanics lien timetable is in 9 V.S.A. ch. 51, subch. 1, and every rule on this page is written for any project type.
Section 1921 grants the lien in two parts. Subsection (a) covers the person proceeding under a contract or agreement, written or not, for erecting, repairing, moving or altering improvements to real property, or for furnishing labor or material for them. The table lists that person as the direct contractor, and the preliminary notice row for the direct contractor reads None required [1].
Subsection (b) covers a person who contracts with an agent, contractor or subcontractor of the owner and performs labor or furnishes materials. Its notice rule is listed for subcontractors, sub-subcontractors, suppliers and laborers [1].
From the lien filing stage on, each rule names all five roles: direct contractors, subcontractors, sub-subcontractors, suppliers and laborers [1] [3].
How the periods run
The notice to the owner. The subsection (b) lien arises by giving written notice to the owner, or to the owner's agent having charge of the property, that the person claims a lien for labor or material. The rule reads Written notice to the owner or the owner's agent having charge of the property, with no period stated [1], so the calculator gives it no date. Section 1921(b) ties the reach of the lien to the notice: it extends to the portions of the contract price still unpaid when the notice is received [1].
The notice of lien. Section 1921(c) limits how long a lien lasts without a filing. The period is Within 180 days from the time when payment became due for the last of such labor performed or materials furnished [1]. The lien does not continue in force for more than that time unless a notice of the lien is filed in the office of the town clerk [1]. Section 1923 describes the filing as a "written memorandum", signed by the claimant and filed for record in the clerk's office of the town where the real estate is situated [2]. The day payment became due is not one of the dates the calculator takes, so this row has no counted date.
The suit. Section 1924 sets two suit periods, and neither is a default. Each one turns on whether payment is due when the memorandum is filed.
If payment is due at the time the memorandum is filed, the period is 180 days after the memorandum is filed [3]. The calculator counts this one from the filing date entered.
If payment is not due at the time the memorandum is filed, the period is Within 180 days from the time such payment becomes due [3]. That date is not a calculator input, so the row shows no counted date.
In both cases the statute speaks of commencing an action for the payment and causing the real estate or other property to be attached [3].
Counting the days
1 V.S.A. § 138 is Vermont's general counting rule: the day, date or act a period is reckoned from is not counted, unless otherwise provided [4]. The calculator leaves out that first day.
