NSO Bell Building, Detroit, Mich.

The 1929 Michigan Yellow Pages Building, with its iconic Yellow Pages sign (that changed colors with the weather forecast), had been vacant for 20 years and was deteriorating along with its Detroit neighborhood.

Following a $51 million rehabilitation, the NSO Bell Building is now comfortable, low-income housing for the homeless and offices for 200 employees of a social service organization that can help residents get back on their feet. The project never would have gotten off the ground without the historic tax credit. Today, the building is leading the neighborhood’s revitalization and is a beacon of hope for the city’s homeless population.
