According to Bard College (who is keeping a running total of local drone laws) there are now over 130 local laws in place for drones across the nation. Almost every week there is a new law being proposed or a new law being enacted.
The most recent major drone regulation to go into effect is in San Diego. Due to its natural beauty, beaches and other tourist attractions San Diego has been a hot spot for drone activity and local authorities thought it was best to regulate drones use for safety issues. San Diego took a common sense approach and basically took existing FAA regulations on drones and made them part municipal code so police can fully enforce them.
This is in contrast to cities like Orlando, Florida that are adding extra lawyers of control to existing FAA regulations. For instance, even though the FAA has an official drone registry, the city of Orlando requires those who want to operate inside of its city limits to pay a fee and register with the city.
Then there is a proposed law from Toms River, New Jersey which would effectively ban drone flight below 400 feet. The city says it is doing this to limit aggressive real estate agents who have been using drone video to show off properties. The city also says it would still allow drone flight, but there needs to be consent from the owners of the property that is flown over. The real questions here is does Toms River even have the authority to ban flight below 400 feet?
