Hooper,
I think you need to be at least 75 feet AGL and preferably transitting, not hovering. Anything less is likely to create issues and mostly frowned upon.
The most I would say in this situation is, "ma'am, I am a commercially licensed pilot doing a job for a paying customer, I have no desire to invade your space or disturb you any more than is absolutely necessary. I assure you, I will leave just as soon as I have completed the job, and I apologize for any inconvenience to you.
And you ARE a commercially licensed pilot I hope.
I hear about people complaining about noise, etc. What's the difference between a pilot spending 30 minutes getting pics of some property with a drone that makes a bit of noise versus a lawncare company that shows up at 7:30 in the morning and runs a mower, and a line trimmer and leaf blower for an hour?
So that's my take on it. I'm new to drones, but have 35 years in customer service and sales. For what that's worth to you.
We ALL, as the front line of integration between the public and this incredible new technology, have a responsibility to represent ourselves and the industry in a positive manner. Please keep this in mind when faced with a challenging situation.
Good luck out there.
