Cal. SHC § 8650

(a) Except as provided otherwise by the legislative body pursuant to Section 8650.1, the bonds shall be issued in series and an even annual proportion of the aggregate principal sum thereof shall be payable on the second day of September every year succeeding the first 12 months after their date, until the whole is paid. The bonds shall bear interest at a rate not in excess of the maximum rate permitted by law from the 31st day after recording the assessment if the assessment was levied under the Improvement Act of 1911, or from their date if the assessment was levied under the Municipal Improvement Act of 1913 or other law, on all sums unpaid, until the whole of the principal sum and interest are paid.

(b) Interest shall be payable semiannually on the second day of March and September, respectively, of each year. The first payment of interest shall become due on the interest payment date which is six months before the maturity of the first series of bonds, but, if any portion of the interest is funded, the legislative body may specify that the first payment of interest shall become due on any earlier interest payment date following the date of the bonds. Interest shall be payable to the registered holders of the bonds as their names and addresses appeared on the records of the issuing agency or its registration agent on the 15th day of the calendar month preceding the interest payment date.
