Union County, Iowa, has about 12,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Union County depends on where the incident happened: the Union 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 Iowa Open Records Law (Chapter 22) 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 Union 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 Union County that is the Union 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.
Reports from the Union County Sheriff's Office
The Union County Sheriff's Office is the county agency; it had 2 violent and 14 property crimes reported for 2025 and reported 55 arrests for 2025.
Its reports come from its records unit, reached through the office at (641) 782-7717. The office's page SearchSystems verified is its jail page, at unioncountyiowa.gov/departments/sheriffs-office/jail (page title: Union County Jail | Union County, Iowa), phone (641) 782-7717, 302 N. Pine St. Creston, IA 50801, which answered when SearchSystems opened it on October 4, 2026.
Reports from the City Agencies in Union County
The one city the FBI lists in Union County with a reporting agency of its own, with the police records page SearchSystems verified where the city has a guide:
- Creston: 33 violent and 63 property crimes reported for 2025; 282 arrests reported for 2025. The Creston police department's page is at crestoniowa.gov/2158/Police, phone 641-782-8402 (verified September 26, 2026).

What the Iowa Open Records Law (Chapter 22) Requires
Under the Iowa Open Records Law (Chapter 22) the agency must answer a request without delay; the law sets no fixed number of days, and a delay past 20 days must be justified, and it may charge the actual cost of copying and retrieval. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
A defendant who has been charged gets the report through the case: the County Attorney, (641) 782-1730, handles discovery for pending cases.
