I am wanting to start a petition in Montana to make it illegal to charge First,Last and Deposit on rental properties. It is illegal in other states. I believe that you should only be able to charge first and last or first and deposit just like the California law... would you sign the petition???? California law puts a limit on the deposits that the owner can ask for, no matter what they are called. All of them cannot add up to more than the cost of two months rent for an unfurnished apartment or three months rent for a furnished place
