Hawaii Notice Requirements

Private Works — No Preliminary Notice Required (H.R.S. §507-41 et seq.)

Hawaii is one of the few states that does not require any preliminary notice as a condition precedent to filing a mechanic lien on private construction projects. Under H.R.S. §507-41 et seq., contractors, subcontractors, materialmen, and laborers may file a mechanic lien application without first serving a Notice to Owner or any other preliminary document.

This means that all tiers of claimants — from prime contractors down to laborers — have equal access to mechanic lien rights from the first day of furnishing labor or materials, without any advance notice obligation. However, claimants should still maintain thorough records of all work performed and materials supplied to support any future mechanic lien claim.

Private Works — No Other Notices Required

In addition to the absence of a preliminary notice requirement, Hawaii law does not mandate any other intermediate notices on private projects. There is no statutory requirement for a Notice of Nonpayment, Notice of Intent to Mechanic Lien, or similar demand notice before filing a mechanic lien application with the Circuit Court.

While no notices are legally required, best practice dictates that claimants send written demands for payment to the property owner and contracting party before pursuing formal mechanic lien remedies. Such demands can facilitate resolution and demonstrate good faith in any subsequent legal proceedings.

Public Works — Notice to Contractor and Surety (H.R.S. §103D-324)

On public works projects in Hawaii, payment bond claims are governed by H.R.S. §103D-324, which requires a minimum 100% payment bond. Subcontractors, materialmen, and laborers who are not in direct privity with the prime contractor must serve a written notice on both the contractor and the surety within 90 days of the claimant's last furnishing of labor or materials.

This notice is a critical prerequisite to pursuing a payment bond claim. Failure to provide timely notice within the 90-day window can result in the complete loss of bond claim rights. The notice should clearly identify the claimant, the project, the amount claimed, and the dates of furnishing.

Public Works — Who Must Serve Notice

The following parties must serve notice on the contractor and surety to preserve their payment bond claim rights on public projects:

• Subcontractors not in direct privity with the prime contractor
• Materialmen and material suppliers furnishing to subcontractors
• Laborers who provided work on the project but are not employed directly by the prime contractor

Service Methods and Best Practices

While H.R.S. §103D-324 does not prescribe a specific method of service for the 90-day notice, claimants should use methods that create a clear record of delivery. Certified mail with return receipt requested is strongly recommended, as it provides proof of both mailing and receipt.

Claimants should retain copies of all notices sent, along with proof of delivery, in their project files. This documentation will be essential if the claim proceeds to litigation. Hand delivery with a signed acknowledgment of receipt is also an effective method of service.

Consequences of Failing to Serve Notice

On private works, the absence of a notice requirement means that claimants will not lose mechanic lien rights for failure to serve any preliminary notice. However, claimants must still comply with all mechanic lien filing deadlines under H.R.S. §507-42 through §507-43.

On public works, failure to serve notice on the contractor and surety within 90 days of last furnishing under H.R.S. §103D-324 is fatal to the bond claim. The claimant will be barred from recovering under the payment bond, leaving only potential breach of contract remedies, which may be significantly more difficult to pursue.
