Crack houses started popping up in tight knit lack neighborhoods due to landlords renting out to single parents or those pretending to be single parents in ADC. The parent then move in the drug dealer who is either a boyfriend or grown son whatever. The house become a drug house then the woman move out and the landlord didn't come and check on his/hers property. The house get shot up or set on fire by rival drug gangs. Well established residents on the street are too afraid to call the police or the police raid the place but the drug dealer come back and set up shop again running the good residents away leaving no one on the street but careless renters. Within a few years the neighborhoods goes down such as had happened to Gratiot from Conner to McNichols and throughout Detroi5
