Should Santa Barbara cap granny flats?

The lack of affordable housing is one of the biggest issues facing Santa Barbara and the rest of the state. It’s such a problem that in 2016, California passed a law requiring cities to allow granny flats - basically small units on single family properties - without environmental review. The hope is that these small homes will add to the housing supply and bring rents down. But could too many Accessory Dwelling Units (ADUs) flood neighborhoods with too many people and ruin their charm?
