Ideas for 1,000 sq ft shop in a residential area.

[Jordan Filbrun]

I bought a duplex in a city and it has a 1,000 sq ft metal shop on one side. It's insulated, concrete floor, full bathroom, garage door, utility sink, heater. It's in a great location for our city but its basically in my tenants backyard. I do need to be thoughtful about who I place there and the hours they keep. Not to mention the city has requirements for how many walk up customers throughout the day etc. I was thinking it would be perfect for a painter, plumber, electrician, landscaper, etc. They work 7-6 roughly and would mainly use the place for storage and parking and office space. I have had some bites but so far no one is a great fit. I have posted it for storage space too. I also thought it could be made into a 1 or 2 bedroom as well but that would require about $20,000 worth of work and I absolutely do not have the cash for that at this point. Are there any outside the box ideas?
