Do you need to file FAA Form 7460-1? Check your exact spot — free.

Cranes, buildings, towers, signs and solar arrays near airports must be reported to the FAA at least 45 days before construction when they exceed 14 CFR Part 77 notice criteria. Enter the address and height to see whether notice is required and the tallest structure you could build there without filing.

FAA Part 77 notice — the short version

When is Form 7460-1 required?

Under 14 CFR 77.9 you must notify the FAA if your structure would be more than 200 ft above ground, or if it would penetrate an imaginary surface rising from nearby public-use or military airports: 100:1 out to 20,000 ft from airports with a runway longer than 3,200 ft, 50:1 out to 10,000 ft from smaller airports, and 25:1 out to 5,000 ft from public-use heliports. Construction on airport property always requires notice.

Does this include cranes?

Yes. Temporary construction equipment such as cranes counts at its maximum operating height. File at least 45 days before the crane goes up.

How is this check calculated?

We measure the horizontal distance from your structure to the nearest point of the nearest runway using FAA runway data (updated every 28 days), take that point's elevation from surveyed runway-end elevations, and compare the surface height with your structure's top (ground elevation from USGS 3DEP lidar plus your height).

What does the packet include?

A documented Part 77 analysis with map, and every value you need to enter in the FAA's OE/AAA system — coordinates in NAD83, site elevation, structure height above ground and above sea level, nearest airport. If notice isn't required, the analysis documents why (useful for permits, insurers and lenders).

Is this an FAA determination?

No. Only the FAA issues determinations. This is a screening and filing-preparation service; confirm with the FAA's free Notice Criteria Tool and file through OE/AAA yourself.
