A Florida Notice of Commencement is a legal document that is used to protect lien rights on a construction project. It notifies potential claimants of the beginning date of the project and the names of those involved in the project. This document is typically filed with the local county clerk's office and with the building department in the county or municipality where the project is located. The Notice of Commencement must be filed before any construction begins. There are two different types of Florida Notice of Commencement. The first type is a Preliminary Notice of Commencement, which is filed before construction begins and provides general information about the project. The second type is a Final Notice of Commencement, which is filed after construction is complete. This document identifies the contractor and any subcontractors, lists the materials used, includes the date construction began and ended, and provides a detailed description of the project. Both types of documents are important to provide legal protection for those involved in the project.
