FAR 91.119 [1] Proscribes what you describe. Flight below 1000' from the highest obstacle within 2000' horizontal is disallowed in congested areas (cities, towns, etc), and disallowed below 500' AGL in other than congested areas. Clearly small UASs are going to be exempt from those parts akin to the exemption for helicopters in subsection d. But there is no exemption for any aircraft from subsection a, so I'm curious how commercial or hobbyists comply with that.
