San Antonio’s public housing authority, Opportunity Home, is offering relocation assistance to tenants at the Soap Factory Apartments. The Soap Factory, which offers rare affordable housing units downtown, became a political flashpoint after local real-estate developer Weston Urban unveiled plans to demolish the complex to make room for the San Antonio Missions’ proposed $160 million baseball stadium. Opportunity Home is prepared to offer units at its nonprofit mixed-income Beacon Communities to those displaced by the plans.
