Seeking if a person lived at given address in 1912

Hi there, I am searching or better try to find out if the sponsor of  my relative really lived under the address given in the passenger list and went through Ellis Island or it was just a fake address. Where do I start or I could find out? We are talking about the year 1912 and do I have to look at the census? For appreciate any help or suggestions to find further information. Thank you.
