The two goals erased a 1-0 D.C. lead provided by Jaime Moreno, who notched his eighth goal of the season.
The result left the Earthquakes with a record of 6-12-7 and D.C. at 8-7-12. Both teams are still in contention for playoff berths.
In their next games San Jose plays New York and D.C. takes on Chivas USA, both on Saturday.
