Establishes the "Preserving Freedom from Unwarranted Surveillance Act" and modifies provisions relating to the use of unmanned aircraft

HB 209, titled the "Preserving Freedom from Unwarranted Surveillance Act," requires state law enforcement agencies to obtain a warrant before using drones to gather evidence about criminal activity, except during emergencies like fires, hostage situations, or search and rescue. It prohibits drones from surveilling private property, farms, or agricultural facilities without the owner's consent or a warrant, and makes illegally collected drone evidence inadmissible in court. The law allows exceptions for emergency response, utility inspections, educational research, and certain activities like fire department operations or real estate marketing. It also restricts drone use near large open-air venues (e.g., stadiums) and waives state immunity for civil lawsuits over violations.
