Significant Changes to California's Mechanic's Lien Law

Major changes have taken effect to California’s lien laws. Originally signed into law on September 30, 2010, Senate Bill 189 (“SB-189”) rephrases and reorganizes all California Civil Code provisions dealing with Mechanic’s Lien Law, from sections 8000 to 9566 and including the stop notice, payment bond, and prompt payment statutes on both private and public works.

Two changes took effect on January 1, 2011. First, Civil Code section 3084 requires that the lien claimant serve a Notice of Mechanic’s Lien on the owner of the property to be liened before recording the lien. The Notice of Mechanic’s Lien must also include a signed “proof of service affidavit” to be enforceable. Second, Civil Code section 3146 makes it mandatory to record a Notice of Pendency of Action within 20 days after filing a mechanic’s lien foreclosure lawsuit.

Beginning on July 1, 2012, the balance of SB 189 took effect, making many additional, significant changes to Mechanic’s Lien Law. Although not every change is identified, some of the most meaningful changes are detailed below.

With the exception of the thirty-six enumerated sections identified in SB 189, Section 107 states that the recodification “is intended to be nonsubstantive in effect.” Court decisions interpreting the former laws continue to apply, but the full effect on prior court decisions remains uncertain.
