On the TV show "Monk", what police department does Adrian Monk work for?

On the TV show "Monk," Adrian Monk works as a consultant for the San Francisco Police Department.

Monk is introduced as a brilliant former homicide investigator who left active police work after the death of his wife, Trudy. The trauma intensified his obsessive-compulsive disorder and made returning to regular police duties difficult. Despite no longer serving as a conventional detective, he continues helping the department solve unusually difficult cases.

His official role is often described as a private consultant to the SFPD. Captain Leland Stottlemeyer, Monk’s former colleague, regularly brings him into investigations, while Lieutenant Randy Disher assists with the department’s cases. Monk’s extraordinary observational ability allows him to notice tiny inconsistencies that other investigators overlook.

The show is set primarily in San Francisco, and the city functions almost like another character, with recognizable streets, landmarks, and police investigations shaping the series. The key distinction is that Monk works with the department as a consultant, rather than serving as a full-time active officer.
