In most States a preliminary notice (also known as a prelien, construction notice, or notice to owner) is a letter that is sent to all interested parties on the project. The notice typically contains information about the project, your role and what services or materials you’re providing to the project. The information, wording and sometimes the form of the document can be dictated by State Statute. Oftentimes these notices secure lien rights and give you leverage in the event of non-payment. Each State has differing time frames and procedures that need to be adhered to when sending a preliminary notice, construction notice or notice to owner.
