I lived at this house for a little more than 1 year. The house was tight, and the landlord stored a lot of stuff. The landlord was very unlawful and unreasonable in terms of handling the security deposit. After I moved out, not only did the landlord fail to return my deposit or any itemization within the 21 days deadline, she was very rude about it. This woman made up falsifying claims over text messages in order to justify her keeping all the money. I tried to reason with her and showed evidence to challenge her claims but she unreasonably disregarded them.
I recommend protecting yourselves by understanding the CA landlord-renter laws if you plan to or are currently renting. Small claim court is also one way to resolve civil disputes.
