No standalone drone ordinance was located in the Rialto Municipal Code (Municode publisher, Titles 1-18). Recreational drone flight in Rialto is governed by FAA Exception for Limited Recreational Operations (49 U.S.C. §44809), Part 107 for any non-recreational use, and California's privacy and emergency-response statutes — Penal Code §402b (interference with first responders), Penal Code §11414 (harassing a child with intent), and Civil Code §1708.8 (aerial constructive invasion of privacy). Rialto sits beneath the San Bernardino International Airport (KSBD) Class D shelf and adjacent Ontario International (KONT) Class C; LAANC authorization through B4UFLY is generally required across most of the city.
A search of the Municode-published Rialto Code of Ordinances surfaced no chapter regulating unmanned aircraft systems (UAS), drones, or model aircraft. Recreational flyers must follow the FAA Exception (49 U.S.C. §44809): pass The Recreational UAS Safety Test (TRUST) and carry proof; register any aircraft 0.55 lb (250 g) or more with the FAA and display the registration number; fly under 400 ft AGL in Class G; remain within visual line of sight; yield to manned aircraft; and never interfere with emergency response. Rialto lies under the San Bernardino International Airport (SBD) Class D airspace shelf with Ontario International (ONT) Class C just to the southwest — controlled airspace authorization (LAANC) is required for nearly all flights inside city limits. Cal. Penal Code §402b makes it a misdemeanor to operate a drone that interferes with the activities of emergency-responder aircraft. Cal. Civil Code §1708.8 imposes civil liability — including treble damages and disgorgement of profits — for using an aircraft (including UAS) to capture images of a person engaged in a personal or familial activity in a manner offensive to a reasonable person. The (now-closed) Rialto Municipal Airport (L67) was decommissioned in 2014, but its former approach corridor still warrants situational awareness around the Renaissance Marketplace redevelopment site.
FAA civil penalties for unregistered or out-of-rule flight can reach $27,500+ per violation, plus criminal penalties up to $250,000 and three years in prison for the most serious interference offenses. Cal. Penal Code §402b interference with first responders is a misdemeanor up to one year in county jail. Civil Code §1708.8 privacy claims allow general, special, and treble damages plus disgorgement of any profit from the captured image.
