Since the California Mechanic's Lien Law was established more than 100 years ago, it has been black-letter law that a contractor or materials supplier has no right to assert a mechanic's lien against public property. Thus, contractors and material suppliers (and even legal practitioners) have resigned themselves to the notion that the only available remedies on "public projects" are claims against payment bonds and the enforcement of stop notices. Within the last few years, however, the inflexible rule that "you cannot lien public property" has begun to change.
