Do not call him. When you end up in court you can show the judge the letter with the certified mail return receipt.
I promise you the landlord will forget about your phone call by next week.
It can be a friendly letter, just advising him that you saw him at your property and that you never received notice that he was coming over. Make it clear and to the point.
My old douchebag landlord used to come over twice a week and pretend that he was watering the plants. But, really he was just checking on the place, which I understand why, since it was in Mission Beach and there were plenty of dirtbags around. However, it was really annoying.
Anyway, I sued him in small claims after he withheld our security deposit for no apparent reason. WE WON!!!! Our whole security deposit back, plus two months worth of rent.
Trust me. Judges have no sympathy for dirtbag landlords, and Judges love documents, they don’t love it when you say I called him immediately after the incident and asked what he was doing there. Landlord replies, “He never called me”
WRITE a friggin letter to the dirtbag. Tell him that you will call the cops next time he is there if he doesn’t give you 24 hour notice.
