The YIMBY  (Yes-In-My-Backyard) movement is fairly new.
In the United States, early leaders of the YIMBY movement include Sonja Trauss in San Francisco and Nikolai Fedak in New York. The first ever Yes In My Backyard conference was held in Boulder, Colorado, in June 2016.
Nikolai has done an amazing job at chronicling the explosion of new development in NYC over the past several years with his must read web site New York YIMBY .
One of the misconceptions with the NIMBY  movement which is largely the opposite of YIMBY is the idea/rule of thumb that low-income housing always drags down property values of nearby properties. In an era challenged by the lack of any type of affordable housing, this makes a bad situation worse.
According to this recent research by Trulia (FYI – I was part of their industry advisory board from 2006-2014), and notably in aggregate form, the impact seems to be non-existent in the majority of the markets covered. One can’t conclude there is no impact as a general rule but it does show that should not be the default assumption.
The above infographic is from this Weekend’s New York Times’ real estate section column called ‘Calculator’ – Low-Income Housing: Why Not in My Neighborhood? . The methodology used in the Trulia research was the following:
To measure this, Trulia compared the median price per square foot of nearby homes (within 2,000 feet of low-income housing) with that of homes farther away (2,001 to 4,000 feet) over 20 years, starting 10 years before the low-income housing was built and ending 10 years after.
