A few things to take into consideration when inspecting with a drone, does the client have pets and will the pet be upset or possibly destroy your drone.
The safest option is to have the client bring the pet inside since most animals have not seen a drone before and the reaction to it could be bad.
For example, a few years ago when I got one of my drones I was testing it in my back yard. My wife let the dog out while I was flying the drone and it led to one pissed off French Bulldog!
One last thing to mention if you are a drone owner. Territorial birds can and will quickly destroy your drone. If you see a swarm of birds chasing your drone or a larger bird of prey getting close to your drone, bring it down quickly!
