If I remember the rules correctly you are allowed to fly over private property as long as it isn’t fenced off. You cannot overfly buildings without permission. You can take pictures of private property without permission as long as they don’t contain anything personally identifiable (ie. don’t take pictures of people, but no people is fine).
You don’t need to actually write it, just raise your hand and we have registered your vote, either via your computer’s camera, Google Nest, Google Assistant or inferred it by analysing the WiFi data returned by your Google Mesh network.
