I am not a attorney I am group home staff who has now worked with 99 different clients in i think 18 group homes during my tenure with the company ) To start with since he is not in a group home or court ordered into programs for DD people you should make sure to follow your states laws to evict tenants whose time is up. Keep your written notice to him short and in plain language so it meets your states laws , it could be as short as date, tenant name and address , this is your notice to move out of X (address ) by date , signed , and date written, when sending it send it multiple ways first off send once copy via confirmed mail delivery and then another copy perhaps the same exact way ( Unless your states laws require something else or consider hiring your county sheriffs department to serve it , you want two different notices because if he tries to tell a judge he didnt get a notice you can offer a second way of showing one was sent and he will have to convince the judge the post office is lying) ( if they will then give them his picture to make it easier. A court is not likely to refuse to accept that kind of service. BAD behaviour well this tenant might think he could get away with destroying the rental unit or other physical aggression directed at the landlord / filer so be prepared the make sure there are consequences such as if he is physically aggressive to people as in assaulting them call police and insist on charges being filed, if he commits property damage call the police and report and i have the courts order restitution, since he has a job it is a income that can be gone after. (unlike the clients in the homes I work in ) BTW if he acts bad a court could indeed require him to live in a facility to be monitored like a group home and or eventually take away his self gaurdianship) any way best wishes to you , I have to get to bed so i can be back to work by 3p ( do not allow him to use a claim of disability in court as a reason to delay a eviction if he wont go after proper notice is sent and if you were able to county that claim then make sure the court understands that he is high enough function that he has a federal job and should not be able to delay a eviction.
