Sts. & Hy. Code, § 3115

(a) This section applies only to assessment districts. The lien duration provisions of subdivision (c) apply to any assessments, regardless of when levied and which are being levied on the effective date of the act which amended this section during the 1986 Regular Session of the Legislature.

(b) From the date of the recording in the office of the county recorder pursuant to Section 3114, or if the assessment district is located in two or more counties then from the date of the recording in the office of the county recorder where a notice is last recorded, all persons are deemed to have notice of the contents of the assessment.

(c) Immediately effective on the date of the last of the recordings, pursuant to subdivision (b), each of the assessments is a lien upon the property against which it is made. Unless sooner discharged, the lien continues for the period of 10 years from the date of the recordation or, if bonds are issued to represent the assessment, until the expiration of four years after the due date of the last installment on the bonds or of the last principal coupon attached thereto, or until four years after the due date of the last installment on any refunding bonds or of the last principal coupon attached thereto, whichever is longer.
