30 days to return the deposit; cap 1 month's rent.
The deposit, with interest if held over a year, and an itemized statement are due within 30 days of move-out. Deposits are capped at one month's rent or $100, whichever is greater.
What this means for you: Bad-faith retention can cost the landlord double the deposit.
Your next step: Provide a forwarding address; send a demand if 30 days pass.
