If the project is valued over $2,000, the informational notice must be sent at the time of the contract's execution. If it starts under $2,000 but rises over $2,000 after the contract starts, the notice must be sent within 5 days after finding out about the increased contract value.

Public projects

GCs aren't required to send 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 required to send a n notice of right to lien on private projects.

  • Notice must be sent within 8 days
  • Notice CAN be sent late
  • Notice is sent to owner, mortgagee, or other interested party

While only some material suppliers are required to send notice on commercial projects, it is best practice for all suppliers to send the preliminary notice of right to lien on all commercial projects, as well.

Send a Notice

Public projects

Subs and suppliers do not need to send a preliminary notice on public projects.

However, sending preliminary notice even when not required is generally beneficial to promote visibility, open channels for communication, and streamline payment.
