Single-family homes cover almost half of Los Angeles
&gt;As Morrow points out, Los Angeles was zoned to hold up to 10 million residents in 1960. By 1990, the city had capacity for just 3.9 million residents.<p>That single line sums up a huge source of problems in Los Angeles from high rents to homelessness to traffic to lack of public transit.  People want to move to, live in, and work in the city, but its zoning laws have unnaturally restricted growth for decades.
