RCMP officers wearing bulletproof vests and balaclavas entered the clubhouse shortly after three p.m. PT.
The area was cordoned off and heavily policed while gang members displaying Hells Angels patches watched from across the street.
When the search was over, officers loaded a number of black bags into a white SUV before leaving.
The search was conducted by the RCMP's southeast district drug section.
Mounties are expected to release more details on Monday.
