This is a big dilema,because any damages done to your basement will be your own costs,and there is no way for courts to intercede on your behalf,I would start with the norm of giving notices,then I would go online to find Landlord rights/ Landlord tenant rights,there is a booklet online,and you an use this to your advantage,and find a proper way to evict your problem and do it legally.Some of the reasons given can be of good use to you,I really hope this helps you out good luck.
I Rent An Illegal Basement To Someone And Now Having Trouble Trying To Get Him Out. I Live In Nyc, What Is The Consequences Of Renting Out An Illegal Basement? What Are The Steps After I Report Myself So I Can Have My Tenant Removed?
One question, Did you put an add saying you had a rental property? Or did you oblige someone's request to offer a place to reside while he found someother place. Was he paying you as a gesture of greatfulness and now he is no longer welcome? There is nothing legal about this so you can't apply any legal eviction notices other than report him to authorities as an unwelcome guest in your property and you don't feel safe anylonger and wish him to be leave your property because he is not welcomed. Be willing to press charges should he not comply.
Turn the property over to the renter and get out of town...
All of you are proposing illegal eviction. You have to take the renter to court.
