Kitchenette: To add a kitchenette, you will need to install plumbing lines to the location of the sink and any appliances you plan to include, such as a mini-fridge or microwave.

I could potentially finance this work however I financed all of the furnishing costs and I financed mini-split additions to both houses so I really want to get away from adding additional debt.

Mini splits are expensive.

I had given her notice of infractions and told her if it happens again she's outShe brought a mini fridge in that is packed full of food so it leaked and caused the ceiling to cave in the bedroom of the 2nd floor unit.

Mini splits most likely would do the job for a cabin that small.

I even called their phone number to speak to a live person to retrieve the mini sample for the webinar I had to sit through twice (1st one 3/4s of the way connection broke).I remained on hold too long.

Not unlike mini-storage.I did chat with a car wash owner a while back. 

Alternatively, a mini-split with both heat/cooling is also an option; I would reserve this only if it's a nicer (75% quality small apartment unit). 

New insulation added in the whole house and soon mini splits.

This is like mini-billboard advertising... and this is going to get you past all the code enforcement, and you can put a nicer sign out there.
