How to find a cheap, short-term space for a project?
Occasionally I need a few hundred square feet for couple week-long sculpture projects. These projects don't make a big mess or anything like that, and all I need is lighting and ideally a few electrical sockets. Even a parking garage or decaying mall space would work in months where the weather is mild.
  
Does anyone have tips for how to find a place like this on the cheap?   

 * Self-storage lockers don't let you use them as work spaces, and workshops/ garages go for $600/mo minimum in my area 
 * A school or university during the summer would work great, but I assume I'd need to be friends with someone there to get access
 * There are also chronically empty commercial spaces near my home, but I doubt owners would be interested in such a small-fry arrangement  
 * There's a local makerspace but they have a policy of no project storage


Are there opportunities for this type of thing out there? If so, how do I find them?
