Hamilton County, Iowa, has about 15,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Hamilton County depends on where the incident happened: the Hamilton 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 Hamilton 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 Hamilton County that is the Hamilton 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 Hamilton County Sheriff's Office
The Hamilton County Sheriff's Office is the county agency; it had 6 violent and 20 property crimes reported for 2025 and reported 122 arrests for 2025.
Its reports come from its records unit. The office's page SearchSystems verified is its custody page, at hcso.org/justice-center-services/inmate-search (page title: Hamilton County Justice Center | Inmate Search | Hamilton County Sheriff's Office), which answered when SearchSystems opened it on September 24, 2026.
Reports from the City Agencies in Hamilton County

What the Iowa Open Records Law (Chapter 22) Requires
The Iowa Open Records Law (Chapter 22) sets the rules: an answer without delay; the law sets no fixed number of days, and a delay past 20 days must be justified, at a charge of the actual cost of copying and retrieval, from the agency that holds the report.
