Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest and crime counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026. Every office link was opened and checked against the office's own site between September 23, 2026 and September 24, 2026.
Grant County, Washington, has about 105,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Grant County depends on where the incident happened: the Grant County Sheriff's Office 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 Public Records Act (RCW 42.56) 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 Grant County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Grant County that is the Grant County Sheriff's Office 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.

What the Public Records Act (RCW 42.56) Requires
Under the Public Records Act (RCW 42.56) the agency must answer a request within 5 business days, and it may charge for copies at 15 cents a page, and set fees for electronic records. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
Any other county record goes through the county records request page SearchSystems verified, at grantcountywa.gov/755/Administrative-Public-Records-Requests (page title: Administrative Public Records Requests | Grant County, WA).
A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 509-754-2017, handles discovery for pending cases.
