In New York holding onto a rent controlled apartment is a big deal. New York is one of the most expensive cities in the world to rent so when you got a rent controlled place you fight tooth and nail to hold onto it.
Masako Mogi has been living in New York since 1980 but her landlord was trying to prove that her apartment was not her primary residence. They tried to use the fact that her power bill was lower than average.
Thankfully victory prevailed and her lawyers explained that she used to eat out regularly and when at home she cooked sushi which uses very little power.
Sushi saves the day
P.S: The comments are worth checking out on the original Gothamist article just to see how much of a hot issue rent control still is in New York.
