For the US, there's no such thing as private property rights to airspace, and all the laws controlling airspace are exclusively federal. There can be temporary and permanent flight restrictions for events or protected areas, and there are restrictions about flying too close to buildings when operating manned aircraft that don't apply to drones (the opposite, in fact, you can fly at higher altitudes if you are close to a building). Now you can get busted for flying in an unsafe manner, harassment, or any number of privacy violations, but not trespassing. To make matters confusing, there are "air rights," but those have to do with zoning and how tall a building can be made. Nothing to do with flying.
