Not even close. If you fly over anybody's property other than your own without permission, you are trespassing. You also have to worry about zoning laws, rules (common law, not written down anywhere, typically) against "nuisances" (basically, any activity that might annoy someone), and noise ordinances. Furthermore, there is no way to "ask a city" anything. They aren't going to do legal research for you. The opinion of some clerk in a city office is worthless.

Find a club that has a flying field.
