Kansas City Region
Harrisonville is the county seat
Harrisonville is the county seat of Cass County. That means it is the home of the courthouse and the main county offices. These offices include the assessor, the collector, and the recorder of deeds. The assessor figures out what your property is worth. The collector handles your tax bills. The recorder of deeds keeps land and property records. So if you need property records, tax bills, deeds, or most other in-person county business, you will likely go to Harrisonville. That is true even if you live in Belton, Raymore, or Pleasant Hill. The town grew up around a courthouse square, which is common for Missouri county seats. One thing can be confusing: the county also covers some separate cities and a small slice of Kansas City. It helps to keep the layers straight. Your city hall handles city matters. The county offices in Harrisonville handle assessment, collection, and recording. Before you make a trip, check current office locations, hours, and online services on the county’s official website.
