A bill for an act relating to nuisance actions against racing facilities and racetracks. (Formerly HF 230.) Effective date: 07/01/2025.

House File 645 (HF645) is an Iowa law that protects racing facilities and racetracks from nuisance lawsuits filed by property owners who move into the area after the facility is established. If a racing facility was already in operation before a property owner purchased or developed their property nearby, the owner cannot sue the facility for nuisance, taking, or similar claims. This law applies to racing facilities and racetracks in Iowa that were operating before the property owner acquired or improved their property. A "racing facility" or "racetrack" is defined as a designated area or facility where competitive vehicle and motorsport races are conducted, including the track, spectator areas, garages, and any associated grounds or buildings used to operate the races.

The passage of HF645 has been welcomed by the racing industry and local communities that host racing events. Supporters argue that the law provides necessary legal protection for established racing facilities, allowing them to operate without the constant threat of nuisance lawsuits from new residents who were aware of the facility's existence before moving in. This legal certainty is expected to encourage investment and growth in the racing sector, benefiting local economies and preserving the cultural significance of racing events in Iowa.

Critics of HF645 express concern that the law may undermine property rights and the ability of residents to seek redress for legitimate grievances. They argue that while the law protects racing facilities, it may leave property owners who experience genuine disturbances without recourse. Some also worry that the law could lead to increased noise and other disruptions in residential areas, negatively impacting the quality of life for nearby residents.
