Landlord in my Yard Every Day

This past week, he has been over, lurking around the yard, every day. There are several problems that need looking into, but he generally has other people do repairs, and he still hasn’t started to fix anything. The other day, he walked right in the house to replace a screen (or remove the old one — it still hasn’t been replaced). The next day, he came in my room while I was gone and broke my computer charger when he moved my desk to fix the radiator. He didn’t call or leave a note or anything. I called him and told him he really needed to give us notice when he comes over, and he got very defensive. I said I wanted a rent reduction to compensate for my charger, and he started accusing me of breaking the radiator (which was ancient) and of letting the next door neighbor (his other tenant) store his furniture in my side of the house over the summer while I was gone (he claimed this is not covered in the lease, even though I was still paying rent for the three months I was out of town). He told me I was being lippy and that he wasn’t comfortable renting to me. I had to de-escalate things, and ended the conversation without getting him to replace my charger or agree to give more specific notice when he comes over. 

I know he needs to give notice before entering the building, but can he be on the porch or in the yard whenever he wants?
