In 2026, the maximum altitude for flying a drone in the United States without specific FAA authorization is 400 feet (122 meters) above ground level (AGL). This rule applies to both recreational and commercial (Part 107) pilots. If you are flying within a 400-foot radius of a structure, such as a skyscraper or a cell tower, you are permitted to fly up to 400 feet above that structure's uppermost limit. This is to ensure that drones stay well below the "floor" of manned aviation, which typically starts at 500 feet. Additionally, you must be in uncontrolled airspace (Class G). If you wish to fly in controlled airspace (Class B, C, D, or E) or higher than 400 feet elsewhere, you must obtain a waiver or use the LAANC (Low Altitude Authorization and Notification Capability) system to receive real-time approval through a mobile app.
