How would you "change" it? It's just not dense enough to support enough grocery stores/restaurants that everyone could walk everywhere.
Given the absurd cost of housing in the bay area (http://www.slate.com/blogs/moneybox/2013/04/11/san_francisco...), you'd generally just reduce or eliminate height restrictions, minimum building setbacks, and parking requirements. At that point developers will build structures that increase density and support grocery stores / restaurants.
