Has anyone else had LO expelled from assisted living after a week for not following rules?

Why is he sleeping at home? Taking him home does not help him acclimate.

What rules did they say they weren't following?

You say LO has Dementia. If so, an AL is not for him, he needs to be in MC. He also needs to have time to adjust. A week is nort enough. But with Dementia you cannot expect him to understand that he can't leave his room once he put down for the night. Thats why he needs MC.

Well, it sounds as if he is having quite a hard time adjusting to the situation. Read the contract that you signed before he was moved in. The contract has 2 parts - one for a place to live, and one for 'supportive services". The details here are important. Often a facility will insist that you hire 24 hour caregivers to ensure a resident is safe in the 30 days that it takes before you have to move out. The 30 days is the usual landlord's notice to a tenant that they need to vacate the unit - in AL facility or in an ordinary apartment building.

Years ago, my grandmother was thrown out of AL after an episode of urinary incontinence. She had wet onto the floor while sitting in her wheelchair. AL wanted her removed immediately and they repeatedly stated that AL does not provide that level of care and she could not stay. She had been there longer than one week, but really not ALL that long.... They said her care needs were not appropriate based on the wetting accident. AL wasn't messing around either - they expected my parents to immediately leave work, find a place for grandma, arrange transport, and get it done by end of business day. It was already approaching mid-afternoon when the wetting accident took place. It was very tense and a bit unprofessional.
