    Key Fact: Hawaii

    Hawaii shares the same 45-day preliminary notice window as Florida, giving subcontractors and suppliers a reasonable window to protect their lien rights.

    Understanding Hawaii Requirements

    Hawaii requires contractors, subcontractors, and material suppliers to file a Preliminary Notice to preserve their mechanics lien rights. Under HRS § 507-43, claimants must send this notice within 45 days from first furnishing to remain eligible to file a lien if payment disputes arise.

    Failing to send a timely Preliminary Notice in Hawaii can result in the complete loss of your right to file a mechanics lien. This makes compliance with the 45 days from first furnishing deadline one of the most critical administrative tasks for any construction project in the state.
