Cal. Sts. & High. Code § 8689

Within the Bass Lake Improvement District in Madera County, a person who has an interest in any land in the improvement district less than a fee interest, such as a leaseholder or subleaseholder, may pay, and the tax collector may accept payment for the entire assessment or any installment thereon, including the assessment on the fee interest. When the tax collector accepts such payment on a portion or part of a parcel, the tax collector shall record such information as required to identify such payment, and the tax collector may add to such assessment a fee as required to pay any additional costs incurred for accepting such payment on a portion of the parcel assessed. The tax collector shall deposit all such fees in the general fund of the treasury.
