No, but refusing to provide an SSN isn't a protected class, so you can be denied because of it. Ditto for taking a picture of your license.A social security number is not mandatory for a credit check. You can order a credit report with a name and address. Since the SSN is a required field, have them temporarily enter any 9-digit number so they can continue filling out their rental application and complete it. The good news is that you do not need an SSN on an apartment rental application to screen a prospective tenant. In California, you'll need to fill out a form that covers your rental and employment history, income details, and references. Doing a background check without a Social Security number from a rental can often be done. If the applicant does not have a social security number, you generally can't run a credit report or nationwide criminal check. Do not give out your Social Security Number.
