It's normal practice for landlords here to do inspections.
The only thing I'd do differently is ask them to come when you are not working. That is a violation of the DCK's privacy but I doubt you can do anything about it as the landlord has a right to inspect their property as long as they do so according to your state's laws.
Totally understand that it feels intrusive but it's their right and something you must abide by as a tenant.
I'm sorry that it was such an unpleasant experience this time though. Hopefully its not because they (landlord) want to sell.... that would mean another move and that would be awful.
