These Landlords knew exactly what they were doing when they did not put the modifications out to bid. These are investors, know the rules. Ignorance does not give them a "get out of an illegal lease free card". They are the ones who should be being sued. 
Have these individuals purchased other properties, but put them out to bid legally?  
Everyone is downsizing. Being opulent is yesterday. These two investors thought no one would find out, or better yet, didn't even care. Who were the attorneys associated with this deal. Sketchy does not deserve a reward. I would like the state to print a list of all the fancy extras done to the building. I hear it has futuristic extras.Was this lease public information including the remodel cost before it was implemented? 
Then comes Wells Fargo. There are 60 of them, a $12,000,000.00 building. More than enough room, other state agencies will move in as well. 
Why would anyone draw up a contract knowing it was illegal. But they did, and we Thank Them
