Following Eisenberg Village, etc. v. Suffolk Construction Co., Inc. (2020) 53 Cal.App.5th 1201, this decision holds that an owner’s suit seeking disgorgement of compensation paid an unlicensed contractor is a suit for a statutory penalty governed by CCP 340(a)’s one-year statute of limitations.  The discovery rule and other equitable doctrines do not operate to extend that one year limitations period.
