Put in a Californian's name and this website might tell you where they sleep
ucpi.sco.ca.gov
ucpi.sco.ca.gov
There used to be a thing called the phone book that would tell you where people sleep as well.
I would (naively) assume that if the government is confident that your address is correct and up to date, they would inform you of said property à la USPS instead of posting it online for all to see.
(Also, address is not a good way to identify most millenials, who move every 1-2 years. E-mail is a much, much more stable identifier than a sleeping location.)
