Nearly every state (and many cities and towns) have statutes dealing with how landlords must approach security deposits. It's not uncommon for states to regulate how much landlords can collect, how they must hold it, and when it must be returned. We've provided detailed information about security deposit laws in certain states, linked below. If your state isn't linked here, don't worry—we also have 50-state-specific charts listing deadlines for returning security deposits, security deposit limits, and the statutes governing security deposits.
