SODO is a neighborhood in Seattle, Washington, that makes up part of the city's Industrial District. It is bounded on the north by South King Street, beyond which is Pioneer Square; on the south by South Spokane Street, beyond which is more of the Industrial District; on the west by the Duwamish Waterway, across which is West Seattle; and on the east by Metro Transit's Downtown Seattle Transit Tunnel and SoDo Busway, beyond which is the International District and the rest of the Industrial District.
SODO was originally named for being located south of the (King)dome, but since the stadium's demolition in 2000, the name has been taken to mean south of downtown. It includes Seattle's downtown stadium district of Safeco Field (where Major League Baseball's Seattle Mariners play their home baseball games) and CenturyLink Field (built on the former Kingdome site; where the NFL's Seattle Seahawks play their home football games and Major League Soccer's Seattle Sounders FC play their home soccer matches). The Mariners' popular marketing campaign in the early 2000s used the SODO moniker in the catchphrase "SoDo Mojo."
SODO deliberately echoes SoHo in New York City, where, during the 1970s, cheap spaces vacated by departing factories were converted by artists into lofts and studios. SODO has undergone a similar process but has not experienced much of the gentrification experienced by its putative model. Some of SODO's warehouse buildings remain in their original use; others have been carved up for artists' lofts, art galleries, and an assortment of other businesses. One building directly across from Safeco Field houses Pyramid Breweries, Inc. downstairs and a variety of small offices upstairs. As one travels further south along First Avenue S., these conversions peter out, and light manufacturing, warehouses, and warehouse-style retail stores predominate. Starbucks world headquarters is housed in a converted Sears building at First Avenue S. and S. Lander Street.
SODO main thoroughfares are First and Fourth Avenues S. and Alaskan Way S. (north- and south-bound) and S. Lander and Holgate Streets, Edgar Martínez Drive S., and S. Royal Brougham Way (east- and west-bound). The western terminus of Interstate 90 is in SODO, which begins 3,101 miles to the east in Boston, Massachusetts.
According to the 2000 U.S. Census, SODO has a population of 2,602, with a median age of 41.2; 458 residences are owner-occupied and 536 are rented. (This probably slightly understates the population, because there are a certain number of artists living illegally in studio spaces that are not zoned residential, plus a resident homeless population.) The average annual household income is given as $42,208; the racial breakdown is 41% White, 28% Asian, 14% Black, 9% Hispanic/Latino, 3% American Indian/Alaska Native, and 5% other.
