“The new law, which takes effect Jan. 1, also prohibits landlords from collecting that information independently.”
Clearly stated above.
I doubt that would hold up in a court of law. As long as the questions are not based on religion or race there is nothing even this law that can prohibit you from asking what you want. A good example is they cannot prohibit you from doing a credit check. Any smart owner could use that alone to disqualify a potential tenant. No rental history with references equals no rental for you bozo.
