Visit Is Preliminary Notice Required In My State? for an updated answer to this question.

Short Answer: Whether you must send a preliminary notice will depend on (1) your role in the construction project; and (2) where you are performing work.  Typically, those who do not contract with the property owner are the class of party who must send a preliminary notice. But it is only required if you are doing work in a “notice” state.  Below is a map of which states require preliminary notices and which do not.

Long Answer: Those in the construction or construction law business refer to states as either “notice states” or “non-notice states.” This label designates a state as either requiring subcontractors and suppliers to send preliminary notices, or not requiring any such notices. If you are required to file a notice, and do not, you may completely forfeit your lien rights.  Yikes!

Remember:  All Notices Are Not Created Equal: Prelim Notice v Notice of Intent to Lien.  Typically, notices can be divided into two categories: Preliminary Notices and Notices of Intent to Lien.  It’s important to recognize the differences between each and understand which notice your state requires.
