Unless you own the building, you are not obligated to take care of this, the landlord is.
If they aren’t doing that, report them to the city.
Good looking out for your neighbors, but don’t let your landlord neglect shit.
Edit:
In the United States, the Americans with Disabilities act requires landlords to provide their tenants with a habitable place to live (because that’s what they’re paying for).
Additionally, if anyone slips and falls on a property, the owner is legally liable. Those are facts: It doesn’t matter how you feel about them, they are what they are.
Downvoting the person informing you won’t change anything.
Downvote away if it makes you feel better, but if you’re a landlord, maintain your fucking property and take care of your people! Don’t be a piece of shit slum lord.
