2 deadlines NoticeGuard models for Idaho: 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 Every deadline in this app comes from a statute read on the date shown next to its citation - that snapshot can go out of date.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 2026-09-10 (each citation below carries its own date). Rule data from the NoticeGuard app, source commit 22f9300.
Filed with the county recorder, counted from this claimant's own completion of labor or services or furnishing of materials - not from completion of the job as a whole.
What it counts from. 90 days after last furnishing (last day on site).
Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service.
Idaho Code § 45-507 (2) Official source · statute text retrieved 2026-09-10
“The claim shall be filed within ninety (90) days after the completion of the labor or services, or furnishing of materials.”
If the date is missed (the statute's own terms). Stated as a mandatory filing period ("shall be filed within") rather than a separate consequence clause - § 45-507 does not itself spell out what happens if the claim is filed late. Unlike Utah's § 38-1a-501(1)(e) or Florida's § 713.06(2)(a), no "may not claim a lien" penalty language was found in the sections read.
Also stated next to this deadline.
Applies identically to every role, including preconstruction service providers: § 45-501 gives "every professional engineer or licensed surveyor under contract" the same lien right as laborers and materialmen, with no separate notice-and-deadline scheme the way Utah's §§ 38-1a-401/402 have one.
A true and correct copy of this claim must also be served on the owner within 5 business days of filing (§ 45-507(5)) - not modeled here; see limitations.
Action to enforce the lien
Counted from filing the claim of lien. If no enforcement action is commenced (or a payment/credit extension is endorsed on the lien record) within this period, the lien stops binding the property.
What it counts from. 180 days after notice of construction lien recorded.
Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service.
Idaho Code § 45-510 (1) Official source · statute text retrieved 2026-09-10
“No lien provided for in this chapter binds any building, mining claim, improvement or structure for a longer period than six (6) months after the claim has been filed, unless proceedings be commenced in a proper court within that time to enforce such lien; or unless a payment on account is made, or extension of credit given with expiration date thereof, and such payment or credit and expiration date, is endorsed on the record of the lien, then six (6) months after the date of such payment or expiration of extension.”
If the date is missed (the statute's own terms). The statute's own mechanism is that the lien simply stops binding the property after six months with no suit filed ("does not bind ... for a longer period than") - it does not use Utah's "automatically and immediately void" language or Florida's "extinguished automatically" language, so that stronger wording is not used here either.
Also stated next to this deadline.
Approximated as 180 calendar days (6 months × 30), the same approximation style used throughout this app. Six calendar months is 181 to 184 days, so this date always lands on or before the statutory one - never after it.
A payment-on-account or credit-extension endorsed on the lien record restarts this period from that payment/expiration date instead - a data-dependent extension this rule set does not track; treat the shown date as the default, not a guarantee it has not been extended.
Weekend and holiday rollover
NoticeGuard does not model a weekend or holiday extension for Idaho. 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
Day counts are raw calendar days from the anchor date. No weekend/holiday rollover is applied.
The 6-month enforcement period in § 45-510(1) is approximated as 180 calendar days, not a literal calendar-month count - the same kind of approximation Florida's 1-year enforcement deadline makes as 365 days. Depending on which months the count spans, a true 6-calendar-month date can differ from this by a day or two.
Not modeled: the § 45-507(5) requirement to serve a copy of the recorded claim of lien on the owner within 5 business days of filing. That period is defined in business days, not calendar days, and this engine only does calendar-day math - approximating it as "+5 calendar days" could show a deadline earlier than the true one whenever a weekend falls in between. Rather than compute a number that can be wrong in a predictable direction, this deadline is left unmodeled; check § 45-507(5) directly.
Only §§ 45-501, 45-507, and 45-510 have been read. The rest of Idaho Code Title 45, Chapter 5 has not been incorporated, including any residential, bonded, or public-works-specific provisions elsewhere in Title 45 or Title 54/67.
Idaho's claim-of-lien filing period (§ 45-507(2)) does not itself state what happens if it is missed - commonly treated as jurisdictional by Idaho courts, but that is not something read from the statute text itself, so it is not quoted as a consequence here (see the rule's own `consequence` field).
This app generates a document for the claim of lien only - not for the § 45-507(5) service copy (see above) or the action to enforce the lien, which is a civil complaint governed by court rules and local practice, not a form the statute itself prescribes.
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.
