New York State, Landlord/tenant Law: Landlord Breaking Lease

Location: Suffolk County, New York State

My aunt rents a a basement apartment in Suffok County. On Long Island. (Note: NOT NY CITY. NYC has different/additional laws that NYS does not. )

She has a one-year lease that ends in June 2026.

Just like half of Long Island, she had a burst pipe in her apartment. My aunt is currently staying with my mother.

As the landlord is tending to the apartment i.e. replacing the rugs etc. she found that my aunt had bedbugs. I have not been there yet but it looks like they were confined to the couch. (Thank goodness- and yes this is possible because I've seen it happen before).

The landlord is having the place fumigated using Terminix. I explain to my aunt that it's partially her fault for not letting the landlord know ASAP. I told my aunt to offer at least half to haggle and if she didn't accept that, to work her way up to pay the full bill.

My aunt also isn't great at taking care of her apartment so at 82 she probably needs help now but she had a lot of empty boxes howevver the landlord also has almost unrealistic demands like not putting cardboard out on certain days and get this: my aunt can only use "scott" toilet paper... lmao. I told my aunt to tell her to stuff it but she wont'.(personally I would buy 2 rolls of scott, buy cheap and wrap the cheap in the scott packaging. So that's the kind of landlord she is.. ANYWAYYYYY.....

That said, the landlord keeps stating that my aunt is "violation of lease".

Now I know if anything is illegal in a lease, it is unenforceable. I haven't seen a copy of the lease yet. I'm pretty versed on landlord tenant law but this is throwing me for a loop. But my main question here isL

Can the landlord break the lease if everybody is an agreement on how to proceed?

I'm just trying to gather information before I call the landlord and talk to her. Her lease is up in 4 months and an eviction would take just as long.

Thank God my aunt is listening to me and is stopped freaking out thinking she's going to be homeless. I have reassured her that she has every legal right to go back to the apartment.

My aunt cannot stay with my mother longer than the end of the week since my mother lives with my sister who rents and honestly taking care of two 80+ year-old women is like having a daycare with 10 three-year-olds. Lol.

Thanks for any info!!
