AZ - Itemized security deposit deduction

[Arov Smith]

Our last tenant moved out of the house on Dec 15, 2022. As per AZ law we have to send out itemized deduction letter within fourteen days, excluding Saturdays, Sundays or other legal holidays. We were out of city for few days and getting the estimates for paint job (for patches/damages due to unapproved decoration) from the different contractors took time. We mailed the letter on 13th business day and it reached tenant's location on 15th business day. Tenant is saying we were late and required to pay additional amount for refund ?
