There are dozens of governmental entities with the authority to regulate how residents of the Los Angeles metro area can use their land: what owners can build, what they can't build, parking minimums, property setbacks, and other regulations that often apply to new housing.
This jigsaw puzzle of local governments within a single metropolitan area can cause confusion for residents. "Housing and labor markets work at a metropolitan level," says M. Nolan Gray, research director for California YIMBY and author of Arbitrary Lines, a book about how zoning codes harm American cities. "When you're deciding where to live or work, you don't stop your search at municipal boundaries—you look around within an hour or so commute."
