Hawaii Mechanics Lien Law: Deadlines, Notices & Filing Guide
Hawaii mechanics lien rights arise under H.R.S. § 507-43 for private work and § 103D-324 for public projects. Because deadlines key off a recorded Notice of Completion or a court-determined Lien Attachment date, claimants should confirm the actual filing or hearing dates as soon as they are available.
Hawaii mechanics lien deadlines at a glance
Hawaii does not require a statutory preliminary notice on private projects, so lien rights are not conditioned on any early notice step.
A Hawaii mechanics lien application generally must be filed within 45 days of a recorded Notice of Completion under H.R.S. § 507-43. When no Notice of Completion has been filed, the deadline is instead tracked at roughly one year and 45 days from substantial completion, though this is treated as an estimate rather than a fixed statutory date, and claimants should update it once an actual Notice of Completion appears.
A foreclosure lawsuit must be filed within three months of what the statute calls Lien Attachment, a probable-cause date that the court itself determines at a hearing rather than one the claimant can calculate independently.
On Hawaii public projects, a bond claim notice is required within 90 days of last furnishing for sub-tier claimants who are not in privity with the prime contractor.

Who can file a mechanics lien in Hawaii?
Hawaii lien rights extend to general contractors, subcontractors, sub-subcontractors, material suppliers, and design professionals where the statute reaches them, provided they furnished labor, materials, or services to the improvement.
Overview of Hawaii lien practice
Hawaii's lien process stands apart because two of its most important dates are not simply calculated from the claimant's own last day on the job. The 45-day filing deadline runs from a recorded Notice of Completion, and until that notice appears, claimants must rely on an estimated one-year-and-45-day tracking period from substantial completion rather than a hard statutory cutoff. Likewise, the foreclosure deadline is measured from Lien Attachment, a probable-cause date the court itself sets at a hearing, meaning claimants cannot calculate it in advance and must monitor the court docket closely. There is no statutory preliminary notice requirement for private work in Hawaii, which removes one layer of complexity but places more weight on catching the Notice of Completion and the court's Lien Attachment ruling promptly. Public project bond claims follow a more conventional 90-day notice period for sub-tier claimants. As in every state, confirming the correct county for recording, the accurate owner of record, and the unavailability of a lien remedy against federal property remain fundamental to sound Hawaii lien practice.
Common pitfalls on Hawaii projects
No Notice of Completion is only an estimate
Without a recorded Notice of Completion, the 45-day deadline is tracked using an estimated date rather than a fixed statutory trigger, so the actual NOC date should be confirmed as soon as it is filed.
Lien Attachment date comes from the court
The three-month suit deadline runs from Lien Attachment, which is set by the court at a probable-cause hearing rather than calculated by the claimant.
No preliminary notice cushion
Hawaii's lack of a preliminary notice requirement means there is no earlier warning step before the recording deadline arrives.
