How do I cause a power outage in the  city before entering the house? I tried to turn off the electricity in the Shepherd Household and Sunflower City Streets, but I still haven't found anything. Plz let me know if I got you wrong or is there anything else I suppose to do. 

You`re not just turning it off, but do it special way. In Sunflower city there`s a sing that hints how to do it
