As far as this case is concerned, I believe no one is trying to tell the OP what to do because that is his call 100%.Posters are giving him some time tested things to do to try and alleviate the situation before he jumps off the deep end and goes straight for the eviction. 

Before you do anything, check with the local zoning department to make sure you can legally do this.So easy to convert...I converted a garage into a 1 bedroom unit with a laundry room with coin-op laundry attached for other tenants. 

Heating the units and providing hot water is a significant cost (pro forma around 5k annually, but I'm thinking closer to 6k or 7k).This building does have coin op laundry and claims 1k annual from that on pro forma...

I bought a ton of coin-op dryers for a song for my multi-family properties and thought about opening a small laundromat. 

You mentioned "your business" in your excavator example (addressing OP). 

I very much agree with the opinion of the OP and my posts history shows this but here are some realities of my market. 

I’m not seeing any upcoming installments of the Dave Meyer multi family webinars right now but you can catch a replay on the podcast show 694: https://www.biggerpockets.com/...I am glad you were able to point the OP in a direction to find those webinars.

Your idea for basement laundry sounds good, or just increase the rent and provide the washer/dryer included with the rent instead of coin op.

This is not always true, although more likely in this situation due to the service call results.I would have been inclined to give the tenants the benefit of the doubt if the OP had not stated that he had recently been living in and and renovating that apartment and presumably using the oven. 

OP, definitely talk to a lawyer about this issue if you want to pursue it further.
