The state of Iowa has taken a significant step toward enhancing privacy protections for agricultural operations by advancing a bill that broadens the scope of drone regulation. The legislation, Senate File 491, seeks to extend safeguards beyond just secured farmsteads to encompass larger farming properties measuring at least 40 contiguous acres. This initiative aims to provide legal recourse against unauthorized drone activity over these expanded areas. Current laws already impose penalties for piloting drones over restricted zones without permission, categorizing such actions as misdemeanors. The proposed changes redefine what constitutes protected farmland and specify the types of surveillance considered intrusive. Support for the bill is strong among agricultural groups, though some organizations remain undecided or opposed.

In recent years, the use of remote-controlled aircraft in agriculture-related activities has sparked debates about privacy versus public interest. As of 2024, Iowa had enacted legislation prohibiting drones from flying over certain agricultural facilities. However, this new proposal redefines "secured farmstead" to include broader categories of farmland under protection. Under the revised definition, any farm generating at least $15,000 annually in commodity sales would qualify for safeguarding. Senator Dan Zumbach emphasized the importance of preserving farmers' privacy during discussions on the Senate floor, arguing that livestock could be frightened by unmanned aerial vehicles, potentially causing harm to both animals and operations.

The updated bill also specifies the nature of prohibited surveillance more clearly than previous versions. Surveillance now includes capturing identifiable images or sounds that reveal details about farm animals, equipment, or structures. Such activities conducted within 400 feet of designated areas without owner consent would be subject to penalties. Penalties remain consistent with existing laws, but the language now reflects the broader application intended by the amendment. Notably, farms located within city limits are excluded from this protection framework.

While many agricultural advocacy groups support the measure, opposition exists. The Sierra Club's Iowa chapter stands as the sole registered opponent, raising concerns that limiting drone access might hinder efforts to document animal welfare issues at large-scale feeding operations. Meanwhile, several media and broadcasting associations have yet to declare their stance, possibly weighing implications for press freedom in investigative journalism involving agricultural practices.

Having passed through the Senate with overwhelming support—only three dissenting votes—the bill now moves forward to the Iowa House for further consideration. If enacted, it promises to reshape how agricultural privacy is balanced against technological advances in surveillance methods across the state. Advocates argue that these measures will ensure farmers can operate without undue interference, while critics worry about potential limitations on transparency regarding industry practices.
