Ala. Code § 11-53B-7
The municipality, in ordering any repair or demolition the cost of which or any part thereof is to be assessed against any property in accordance with this chapter, may provide that the same shall be paid in cash within 30 days after the final assessment; provided, however, that if the assessed amount is greater than ten thousand dollars ($10,000), the property owner may, at his or her election, to be expressed by notifying the municipal official charged with the duty of collecting the assessments in writing within 30 days after the final assessment is determined, pay the final assessment in 10 equal annual installments, which shall bear interest at a rate not exceeding 12 percent per annum. Interest shall begin to accrue upon the expiration of 30 days from the date on which the final assessment is set by the governing body and the interest shall be due and payable at the time and place the assessment is due and payable.
Any person who elects to make installment payments may pay the outstanding balance of the final assessment together with all accrued interest thereon at any time during the installment payment schedule. The first installment shall be payable within 30 days after the final assessment is determined, and all installments thereof shall be payable at the office of the clerk, finance office, or treasurer of the city or town as may be prescribed. Upon full payment of the final assessments and accrued interest thereon, the municipality shall record a satisfaction of the lien in the office of the judge of probate of the county in which the municipality is located.
