Barnstable County, Massachusetts, has about 233,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Barnstable County depends on where the incident happened: the Barnstable County Sheriff’s Office - MA POST Commission for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Massachusetts Public Records Law requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Barnstable County
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
In Barnstable County that is the Barnstable County Sheriff’s Office - MA POST Commission for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places the Barnstable County State Police in Barnstable County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries Cape Cod Community College (campus police), with a records office of its own.

The Massachusetts Public Records Law sets the rules: an answer within 10 business days, at a charge of staff time after the first four hours for towns and two for the state, plus copying, from the agency that holds the report.
A defendant who has been charged gets the report through the case: the District Attorney, (508) 362-8113, handles discovery for pending cases.
