Establishes a nuisance action for deteriorated property in certain counties and municipalities within those counties

HB 1258 creates two key mechanisms for addressing deteriorating properties in Missouri counties and municipalities with over one million residents. First, it allows local governments to impose a semiannual $200 registration fee on vacant residential or multi-unit commercial properties with housing code violations (after six months of vacancy), with owners able to appeal or fix issues to avoid the fee. Second, it establishes a "nuisance action" enabling neighbors within 1,200 feet or recognized neighborhood organizations to sue owners for property value damage caused by neglected properties, including court costs. Unpaid fees become liens after one year, triggering foreclosure-like procedures similar to unpaid property taxes. The bill directly affects property owners of deteriorating vacant buildings and neighbors impacted by blight.
