MO HB3177

Racing facilities with proper permits and vested development rights are immune from public or private nuisance lawsuits, inverse condemnation claims, or similar civil actions by surrounding property owners who purchased property or built after the facility was established

"Typical racing activities" including engine noise, public address systems, track lighting, dust, race-day traffic, and event scheduling cannot constitute a nuisance when conducted in substantial compliance with applicable laws

Protection applies within a three-mile radius of the racing facility's perimeter and covers racetracks, spectator areas, pits, garages, staging areas, parking, and administrative buildings

Immunity does not apply to material violations of environmental, safety, building, zoning, or noise laws, nor to willful or reckless misconduct or substantial changes in use beyond existing permits

State agencies, counties, and municipalities are prohibited from bringing nuisance actions against racing facilities for typical racing activities conducted in substantial compliance with applicable laws
