you aren't entitled to legal notice, the other tenant may be if state law requires it. typically, landlord would give a cure or quit notice ordering the tenant to clean up.
it looks like state law is 'reasonable notice' to enter.
if its that bad, you need to call the city and adult protective services. the city might be able to get in sooner.
the person could be a mentally ill hoarder...or could have a physical disability that makes them unable to clean adequately. I look fine when you seem me, although you might see my legs give out a little if you watch.....it physically takes me a month to do what a typical person can do in a day. the state provided a paid aide once per week, he failed to show up half the time, napped when he did, and then whined he couldn't follow the care plan when I bribed him candy to stay awake.
i tried getting help from another program, i told them I wanted to hire on my own so I can throw them out if they refuse to do the work they are being paid for......that programed determined that meant i wouldn't let anyone in.
i've had friends I've done a lot for....they don't have 15 minutes to help me....1 has since been arrested for stalking me after I ended the friendship because she was abusive.
I begged churches, synagogues, and mosques for help.....a christian church had been robbed and went on TV insisting they would help anyone who asked....they wouldn't help me...not with money to pay help or just an hour volunteer time.....the mosque that had a letter inviting anyone to ask for help never responded.
yesterday my big accomplishment was typing up the newspapers and cardboard. today I hope to bring them out to the recycling bin.
i can't keep my home up to most people's standards...they would be quick to complain if they saw it...at they same time, they won't even give me 15 minutes of time to help with things I can't do for myself.
I don't let smelly garbage sit around for long though.
i know of at least 3 people who could not keep their homes clean. 1 was a woman that just died at 70. I know she had money to pay for help, but when she died, they said it was a hoarding situation. She had a 1 bedroom condo and they filled a large dumpster. She walked without a cane/walker, but had difficulty. I used to see her carry a 20 pound box of litter without much of a problem though...steps may have been an issue.
the one that moved had a developmental disability and no supports to teach her to do housework.
the 3rd still lives here, someone offered to help him declutter, he declined...he walks with a walker, i don't know if he could afford to pay anyone. he is in his 70s.
forgot about the 4th....my former friend...she is severely mentally ill and has been bad for about 4 years...hospitalized about 6x/year for up to 3 months at a time. she's had mouse drippings in her drawers and cabinets, the sink always is piled with dirty dishes, garbage strewn on the floor...her friends clean it when she is locked up, but it never stays that way....she refuses to use the dishwasher and insists in wastes water when the fact is, dishwashers often conserve water nowadays...certainly does for me since I am slow at washing dishes....she thinks putting things in landfills hurts the environment, so she created her own personal landfill inside.
thumbs are from people who whine about others but don't try to help
