Private projects

General contractors are not required to submit notice on private projects.

However, GCs are required to file a notice of intent 10 days before filing a lien.

Public projects

General contractors are not required to submit notice on public projects.

Since GCs will not make a claim against their own bond for non-payment, they do not have bond claim rights, and have no preliminary notice requirement.

Private projects

Subcontractors and suppliers are not required to send a preliminary notice on private projects.

However, a notice of intent to lien is required in order to retain your lien rights.

  • Must be sent within 10 days before filing a lien
  • Notice cannot be sent late
  • NOI is sent to the owner, the prime contractor, or their respective agents

Note that the notice of intent must include a copy of the lien that will be filed.
