The FAA standard for the county airport I’m at is no structures 250 ft from the runway centerline, after 250 ft you can have a 1 ft rise in building height for every 10 ft set further back from the centerline. So you need to be 350 ft away from the centerline to have a 10 ft tall building......
Those obstruction regs are for FAA funded airports and focus on protecting instrument approaches.I THINK this gives most of the information you are looking for. https://www.ecfr.gov/cgi-bin/text-i...=text&node=14:2.0.1.2.9&idno=14#se14.2.77_117
It is CFR 14 ... PART 77—SAFE, EFFICIENT USE, AND PRESERVATION OF THE NAVIGABLE AIRSPACE
One of the most interesting airspace cases I know of involves Boston Logan. The bay to the south is frequently occupied by ocean going ships. The tower is (was ... maybe still is ... it was a long time ago) equipped with a camera on a tower that could be used to gauge if the ship going past penetrated the airspace, thus affecting approaches to the airport.

As far back as possible, leaving enough room on the back side of the buildings for comfortable access. Most of your visitors will have airplanes, they will need a safe place to park. Also buildings do create turbulence when there is a cross wind. For that reason alone, they should be as far back as possible.Hypothetical situation. 2400 ft grass runway in an airpark. Said airpark has about 19 1.3 acre lots lining the runway on both sides. The lot sizes are 300 deep by 200 wide. What do you think is a safe setback from the runway for buildings.
