So, you’re allowed to fly higher than 400 ft AGL if you inspect a structure and remain within 400 ft radius of the structure. You’re even allowed to fly 400 ft above the top of the structure (maintaining 400 ft radius) and if the altitude is going to cause you to enter controlled airspace you’ll need an airspace authorization.
a dashed magenta outline indicates class E airspace at the surface. Shaded magenta outline identifies Class e airspace at starts at 700ft
