My question involves landlord-tenant law in the State of: Wisconsin
Here's an interesting landlord/tenant situation. I'm currently renting a lower unit in a house converted to 2 apartments. There is an upstairs tenant on a separate lease. I have no flippin idea what she does up there, but she is always tripping breakers. The breaker box is in the basement of the home, and it's accessible via stairs within my apartment. Me and the other tenant have a good relationship, and I will happily and go and deal with the breakers as needed.
However, there's some other factors at play. In the basement there is also a large open crawl space that has access to the exterior of the house. All winter I was live trapping rabbits that entered the basement and couldn't escape. I need to stress this crawlspace is huge, you could probably be on hands and knees in there. I notified the landlord and they indicated they planned on doing nothing about the issue. It's an inconvenience and furthermore a security risk. Yes, I know the obvious advice of "don't like it, move" is on the agenda, but in the short-term I have installed a lock to prevent entry from the basement to the interior of the house. This has the side-effect of preventing access to the basement (from the house) by anyone but me since there is a lock involved.
What ends up happening is I was on a vacation and the upstairs tenant blew the breaker connected to her fridge. Since I wasn't there to deal with it, she called the landlord as an emergency, who proceeded to enter my unit under their rights in an emergency, then flooded me with furious texts/calls when they found out they were prevented from accessing the basement. They said they could give me a 14 day "get the f*** out notice", and those were his words, but they are letting it go this time. At this point, I reminded them I gave them info about the crawlspace and the opportunity to remedy the situation, and technically I didn't prevent their access to the basement as if they really need to get to the furnace or breakers, there's that huge crawlspace they can use. I also offered a key, and they refused saying I can't install custom locks regardless. Nothing about locks, breakers or the basement is specifically mentioned in the lease, which appears to be a cookie-cutter lease with no atypical provisions.
Now for my questions:
1.) Is a tripped breaker a legitimate emergency in which the landlord can enter the unit without notice?
2.) Does their refusal to secure the premises against the crawlspace affect anything? And furthermore, does the fact they could go through the crawlspace negate the argument that they are "denied access"? They have access, it's just not ideal.
3.) Also, is their threatened action of a 14-day move out for breaking lease with no opportunity to cure a thing? If not, what could they actually do if I maintain my present setup? Could I use their refusal to secure the crawlspace as a reason to get out of the lease early if I try and move?
