A recent report said that a family needs about $200,000 a year to live comfortably in San Francisco, so long as their children go to public school.
And in June the median home price hit $1 million.
Wenxin Zhang understands this better than most.
The Chinese-born, California-based photographer moved to the city in 2011 and started reaching out on internet forums to meet new people.
What she found was a community whose members had been displaced by a city hit with skyrocketing prices following the tech boom and the expansion of nearby Silicon Valley.
Zhang decided to start documenting these people and the alternative means of accommodation they had come to call home.

Zhang called the project Goodnight Stories.
'At first glance, Goodnight Stories seems sweet and romantic, but in reality, people who have alternative living situations can have very bitter lives as well,' she told Feature Shoot.
'Some of them suffer from bankruptcy, poverty, health problems or depression.
'Sometimes being different from the majority can be very hard.'
An index on Zhang's website describes the project.
'Goodnight Stories is a narrative photo project taken when I was a new comer in San Francisco in 2012,' it said.
'I found strangers who have alternative housing conditions through Craigslist and visited them alone with mutual trust.
'Embedded with the photographer’s insecurity towards adult world, I has created a bittersweet fairy tale that explores the diversity of habitat choices, and the boundary between reality and fantasy.'
