My first property and I have a headache already 😫

I purchased a triplex about a month ago and I live in the first and inherited tenant on 2 and 3

The lease specificity says one off street car per floor.

I am the first to take blame here when tenant 3 complained about her back and her mom being old it’s a rental and they will get rid of it Thursday

Today is Thursday I call her about it and she basically said she gonna keep parking two cars in the back and for me to do what I gotta do

How should I handle this situation thanks

O and covid 19 does make the situation worse because of the eviction moratorium
