Keep Security Deposit for Unpaid Rent in California?

[DJ Wilson]

I have a house rental in California.  The tenants have been great, but the lease ended on 12/31/24.  They stated they physically moved out, but still had belongings in the property.  They accessed the property until they finished moving everything out on January 8th.  My question is, can I prorate their rent for the 8 days of January and deduct it from their security deposit? There are no other deductions that are needed from the deposit.  Thank you for any help or information!
