The raid at 6:30 a.m. along 48th Drive NE was the result of a lengthy, large-scale investigation, Marysville police Cmdr. Robb Lamoureux said.
Officers were serving a search warrant targeting drug use and sales, he said.
Nineteen people were in the house at the time.
Those persons had a total of 146 prior criminal convictions, he said.
Eleven were arrested Thursday for investigation of drug-related crimes and for previous warrants.
The raid involved a SWAT team, a police helicopter, flash-bang canisters and a remote-controlled robot.
The officers seized a small amount of drugs, some paraphernalia and two vehicles. Police did not report what kind of drugs were involved, and did not respond to questions by deadline.
When police were carting off the suspects, neighbors came outside and clapped and gave officers thumbs up, Lameroux said.
The investigation and planning were considerable, and the end result is a big positive for this neighborhood, he said.
