Generally, a building or obstruction would have to be more than 200 feet tall before we required a light. But this varies based on the location of the building or pole in relation to an airport or flight path.
If the building or light pole is on an airport, please contact the nearest FAA Airports Regional Office.
If the building or obstruction is not on an airport, please contact your local FAA Air Traffic Office.
The regulation covering obstruction lighting is Title 14, CFR Part 77, Objects Affecting Navigable Airspace.
