Interest accrues annually
Regardless of the deposit amount, landlords must follow the correct procedures for holding, itemizing, and returning the deposit. Failure to follow these procedures can result in the landlord forfeiting the right to make deductions and owing penalties to the tenant.
After a tenant moves out, Connecticut landlords have 30 days to either return the full security deposit or provide an itemized list of deductions along with any remaining balance. The clock typically starts on the date of move-out or the date the tenant provides a forwarding address, whichever is later.
If the landlord misses this deadline, the consequences can be severe: 2x deposit for bad-faith failure to return. Tenants should document their move-out with photos, return keys promptly, and provide a written forwarding address to establish the start of the deadline clearly.
