The following excerpt is from People v. Brown, C078699 (Cal. App. 2017):
We note at the outset that these initial questions posed at the front door of the residence did not amount to a detention under the Fourth Amendment. Officers may approach individuals in a public place and ask questions without implicating the Fourth Amendment. (People v. Rivera (2007) 41 Cal.4th 304, 309.) This includes questions posed "at the doorway of a home." (Ibid.)
