There is a sizable community of Part 15 broadcasters, and some run Talking House transmitters, which pop up on eBay.

Part 15 for a campus can cover a much greater area (the entire campus) than can Part 15 for an individual or a non-campus organization.

That is generally not Part 15 - it is generally Travelers Information Service (TIS) which is a licensed service under Part 90, where they operate with a coverage radius limit of 3 km and a TPO limit of 10 watts. I have never been through a construction site operating Part 15, but have been through many operating Part 90, whose transportable transmitters are generally distinctive because of their antenna length, which can be up to 15 meters. I almost always dial in a Part 15 or Part 90 operation when I come across one.

Not necessarily strictly legally. Some of the early satellite-to-FM converters were cited by the Commission as violating Part 15.
