For many Californians, mobile home parks are one of the last real affordable paths to homeownership. Residents typically own their homes, but rent the land beneath them.

Many of its residents say they’ve been dealing with unfair rent increases and fear eviction. These tensions are unfolding in a quiet mobile home park in the Bay Area city of San Pablo.
