San Jose officials have committed a significant public subsidy for the Gateway Tower project, a step that will help the first high-rise workforce housing complex downtown begin construction early next year and add hundreds of much-needed units to the city's housing stock. The City Council approved more than $38 million in loans for Core Cos.' 15-story, 220-unit project at 470 S. Market St. that will ultimately cost more than $197 million to build.
