The Los Angeles Times reports the measure permits parking and sleeping in certain industrial or commercial districts. The ordinance cites unsanitary conditions, noise and crime as reasons for the ban in other parts of the city.
The nighttime vehicle living ban would replace a 1983 law that outlawed vehicle dwelling citywide. That provision was struck down by a federal appeals court.
L.A. Mayor Eric Garcetti hasn't said whether he'll sign the new ban into law.
Its approval Wednesday came a day after voters approved a $1.2 billion initiative to build supportive housing.
