At the edge of the City College of San Francisco main campus, there's a small, invisible neighborhood.
Its residents look out for each other, keep the sidewalks clean and sometimes throw quiet dinner parties. They share tools and recipes, help each other out with projects and give a friendly welcome to newcomers.
But of the 60,000-plus students who attend City College, it's likely that many walk through this neighborhood every day without knowing it's there. And that's exactly the point.
"It is a bit of a paradox," Kyle Murphy said. "Create community, keep below the radar."
Murphy is, according to his friends, the unofficial mayor of this small and flourishing neighborhood. Dotting the edge of campus along Frida Kahlo Way, somewhere around a dozen nondescript vans and work trucks are hiding the handcrafted tiny homes of City College students, attending school in the face of San Francisco's record-high rent.
