The Scooby-Doo Detective Agency clubhouse was a treehouse located in Shaggy Rogers's backyard (next to Scooby-Doo's doghouse). The preadolescent gang frequented there to hang out and solve crimes.
A Pup Named Scooby-Doo
Shaggy told the gang about his stolen bike in the clubhouse.
The gang ran there to hide from a real (but nice) ghost.
The gang met there to discuss things after Velma Dinkley was accused of stealing possessions from Coolsville Junior High School.
Freddie Jones was making wanted posters for Red Herring there when his friends asked him to stop accusing the bully for 24 hours.
Velma demonstrated her teleporter there and then transported them all to New York City.
