The weather is a factor. It doesn't rain much in large parts of Cali. In those same areas, you are generally at low risk of freezing to death and in SF and a few other areas you also won'tbe dealing with excess heat. SF in particular has very homeless friendly policies. I took a class at SFSU years ago on Homelessness and Public Policy. That detail was highlighted during the class.
