It's important to not forget that half of the land in Los Angeles is the Santa Monica Mountains (hollywood hills, ect), and the San Fernando Valley. Now, there are still neighborhoods in central areas that don't have much multifamily housing, but these are the areas that need to be targeted. Multifamily sprawl is just as bad if not worse than single family home sprawl, as it only feeds into traffic. The real problem in LA is a lack of proper transit oriented development, especially around employment. I should also add that LA is the densest metro area in the US, largely because even though LA has so many single family homes, subdivisions are far smaller than you see in NYC suburbs.
