What exactly is the law that states a business has to give you an application?

I hear from a lot of people that if you go to a business and ask for an application and they refuse that that’s against the law. By Law they have to give you an application whether they’re hiring or not and they have to keep it on file for 6 months. I’d like to see the exact law that states that. I tried looking on the California employment and regulations site, but it’s a real mess and hard to find anything in there. I’m hoping someone here can state the exact law.
