No, a preliminary lien notice is not the same as a mechanics lien. While both are related to the construction industry and can lead to the filing of a mechanics lien, they serve different purposes and have distinct timelines and requirements. The preliminary lien notice is a proactive notice sent by subcontractors, suppliers, or other potential lien claimants to inform property owners and general contractors of their involvement in the project and their intention to claim a mechanics lien if payment issues arise. It serves as a preliminary warning before any formal action is taken.
