Are house sitters background checked?

Rover does have a general background check done on all sitters and walkers. But you should familiarize yourself with Rover's position relative to your home and pet:

If you have further questions, I suggest you call Rover's Customer Support at [Edit: Rover’s contact options have changed. Visit the Rover Help Center at https://support.rover.com/ to find the phone number, help articles, or chat with the team] and ask to speak to their Trust & Safety Department.

All sitters are backgrounded checked before the profile is approved. Another good check is reviews - lots of positive reviews is a good sign! Always schedule a meet and greet before booking anything!
