Do ADUs provide affordable housing?

i love this … i was walking in town again today, counting, like i usually do, all the empty buildings that HAVE to be repurposed… befor we add any new buildings..!! Yes, the zoning would have to acco-modate change…thats a new word. i just made .it up…Business buildings with customers at night and empty during the day; manufacturing buildings (on Morris).. still vacant; vacant schools; vacant churches…Who do we think we are??? I’m going to start making lists of dead or dying buildings … anyone want to join me???
