California Code, Health and Safety Code - HSC § 2866

The amount of the lien shall be collected at the same time and in the same manner as ordinary county taxes are collected, and shall be subject to the same penalties and the same procedure and sale in case of delinquency, as provided for ordinary county taxes. All laws applicable to the levy, collection, and enforcement of county taxes shall be applicable to the lien, except that if any real property to which the cost of abatement relates has been transferred or conveyed to a bona fide purchaser for value, or if a lien of a bona fide encumbrancer for value has been created and attaches thereon, prior to the date on which the first installment of taxes would become delinquent, then the cost of abatement shall not result in a lien against the real property, but instead shall be transferred to the unsecured roll for collection.
