Landlords must add interest to your rent deposit equal to the guideline for rent increases during a given year. For 2022, landlords may increase rent up to a maximum of 1.2%, and beginning January 1st, 2023, landlords may raise rent up to 2.5%. Your landlord can either add this amount to the deposit or opt to give it to you directly. This is done so that your deposit is still able to cover your last month's rent regardless of the increase.
