The only thing we can guess is that they may have mistakenly thought that it needed a closet to comply as a bedroom.

I would tell them it is what it is and they are welcome to supplement the air conditioner with portable A/C or window units.

Unless the building consists of 8 hardly-inhabitable, closet-like studios; there should definitely be some upside in rent for you day one.Feel free to reach out if you'd like any assistance running the numbers for the property.

I once sold a house years ago that had equity in it to an investor.The seller was in financial hard times.The house was paid off but then used a loan from a predatory lender who was now trying to foreclose.So I listed for them with plenty of equity left.The seller ended up selling and still getting 15,000 from the sale.The lady had a few cats and then took in strays.The cats started breeding and then more cats showed up under the crawl space where the vent cover was broken and they would go in and out.There was at one point before I listed it 55 cats in there.Animal control came out and got 48 cats out,3 were dead,and 4 were too wild and ran out of the house.She kept most of them in one room and a few in the living room.I tried to help her by cleaning the room and used every cleaner imaginable.I don't care what people say about cleaners they don't work.The only time is if it's just a few place and the carpet pad and subfloor isn't soaked or they sprayed on the wall but not in the corner.If the urine gets under the baseboard or in the corner forget it.You will have to tear out the sheetrock in that area and clean behind it.For subfloor depending on how deep it has penetrated the wood you can sand the top surface off to get rid of the smell.If it's deep you have to rip the subfloor up and replace.What you need to do is take a portable black light and walk around every area inside of the house and outside to see where the marking has occurred.It it's simply the walls and not the floor or corner you can clean easily.You will know by the black light how extensive it is.

He is refusing to pay for portable AC units or put them up in a hotel...meanwhile the house is incredibly hot.

We repurposed the storage tank (it was very well insulated) as storage for a solar-thermal array and put in-line water heaters in each unit to give the solar heated water a boost when needed,The solution was a little pricy going in, but pay-back was forecasted as 4-years.Is there a storage closet in each unit which could serve as home for a dedicated water heater (inline or storage) for the unit?  

I have an owner's closet with a keypad, and the housekeeper restocks from there.  

Another more efficient option would be a ductless or portable heat pump but they are a little more expensive.  

Has anyone used the portable self storage units rather than building a building on a cement pad.
