I stumbled upon the Aircraft and Airports section of the Dallas City Codes
and found a whole new layer of regulations I never knew about.

Here's a good one. As a student, I guess I need to call my instructor
every time I need to start the engine:

SEC. 5-24. ONLY PILOT OR COMPETENT MECHANIC TO RUN ENGINE.
No person shall start or run aircraft engine other than a licensed pilot or
a competent mechanic in the cockpit attending the controls. (Ord. Nos.
8213; 14384)

You have a student pilot certificate, don't you? There's no such thing
as a "licensed pilot," but a solo student pilot is properly
certificated to fly an airplane.

SEC. 5-36. FLYING AT LOW ALTITUDE; PERMITS FOR LANDING PLACES.
No person shall fly any aircraft over the city at a lower altitude than
2500 feet from the surface of the earth

Unenforcible. Only the FAA has authority over aircraft in flight.
