How much am I actually obligated to clean? [MN]

TLDR; sewage pipe bust in our rental a month before our lease was up. We were told not to use water or the septic system. We are moving out but have been told we are still expected to ‘reasonably’ clean the home. What can they actually expect us to have cleaned?

I have been renting this house for a few years now and we are officially out on the 15th (tomorrow). The landlord is Tricon, aka Pathlight/HPA, big corpo with no individual owner/landlord.

The issue: about a month ago, the sewage in the basement of the house burst and flooded one of the rooms. We reported a different drain in the basement backing up with grey water 3/4ish months ago and Tricon sent multiple people out to check but after being told it was a problem with the pipe in our front yard being collapsed they didn’t do anything to remedy the problem.

Anyways, the pipe burst Aug 12th and after a few more visits crime plumbers, we were told we couldn’t use the sewage or the water in the home. Tricon offered us $150 a night at a hotel until it was fixed or our lease was up. We were lucky enough to have just bought a house so we didn’t need to do that.

Now it’s about a month later and we are moving out. They sent us a move out checklist of things they want us to clean and when I pushed back on it being unreasonable, we were told:

“Please be advised that you will not be held responsible for any areas of the property that are directly impacted by the active maintenance work order or the ongoing plumbing/sewage concerns. Given that the plumbing issue is currently affecting the entire home, we have taken this into consideration as it relates to the move-out expectations.

We do ask that you complete any reasonable cleaning that can be performed without the use of running water or the plumbing system. This may include removing personal belongings, trash, debris, and completing general dry cleaning of accessible areas where possible.

Any areas that cannot reasonably be cleaned due to the plumbing restrictions will be taken into consideration during the move-out review.”

I really don’t like not having a defined list of what to clean and this vague ‘take into consideration’ but they won’t clarify it more than this.

We haven’t been able to use the house since August 12th and the sewage is still rotting in the basement.

Part of the things ruined by the sewage was furniture/large objects we cannot take with us— and I’m sure as hell not paying a fee to dump what was perfectly good furniture that I would’ve brought with me to my new house. I also, frankly, don’t want to touch it. So they’re still in the basement.

I also had a cleaner scheduled to come clean the house prior to move out, but this was arranged before the sewage burst. This cleaner was no longer willing to clean a house without running water or functioning sewage. Reasonable. But this was the plan because I’m disabled and cleaning a house myself isn’t going to be fun.

I don’t want to pay extra money to hire someone to clean a home with a biohazardous basement and no plumbing. So I’ll be cleaning it myself but I really dont want to do more than what is reasonable in my situation.

I already don’t plan to hire a profession carpet cleaning company to do the house because from what I understand, that’s not legally required of us in Minnesota.

Any help or insight is greatly appreciated!!
