From the FAA site directly:
WHO MUST FILE?
§ 77.13 - Any person/organization who intends to sponsor any of the
following construction or alterations must notify the Administrator of
the FAA
Any construction or alteration exceeding 200 ft above ground level
Any construction or alteration
within 20,000 ft of a public use or military airport which exceeds a
100:1 surface from any point on the runway
within 10,000 ft of a public use or military airport which exceeds a
50:1 surface from any point on the runway
within 5,000 ft of a public use heliport which exceeds a 25:1 surface
Any highway, railroad or other traverse way whose prescribed adjusted
height would exceed that above noted standards
When requested by the FAA
Any construction or alteration located on a public use airport or
heliport regardless of height or location
Persons failing to comply with the provisions of FAR Part 77 are subject
to Civil Penalty under Section 902 of the Federal Aviation Act of 1958,
as amended and pursuant to 49 U.S.C. Section 46301(a).
Note the slopes and distances of the second criteria above. This means
lighting is required on obstructions (towers) that are below 200 ft if
you are within a distance that gives you the slope stated. It can't hurt
to check. If a plane hits your tower and you were required to light it,
not only will you be sued beyond belief, but you will go to jail. Is it
worth it?
