Building an ADU in L.A.- Part II (excerpt)

Between 2003-2016, an average of one hundred permitted ADUs had been developed each year in L.A.. While 100 ADUs a year is something, it’s certainly not a lot of housing for a city with a population of nearly four million people, and 1.4 million housing units. But, 2017 has entirely changed the landscape for ADUs in California at large. And, L.A. has done something that no one expected.
