I guess you missed the reading and comprehension part in your vast edumacation.
1. Never a complaint from either tenants or management. Especially since we train 1/2 that park.
2. No one there after 6pm or weekends.
To the general public, we're talking non-training fatties, they probably see you as steroid-head brutes making all sorts of racket driving their business away and dinging their cars. not that you do either - but that's how fat haters perceive it, and probably report it to the building manager.
The manager doesn't want a 'he said, she said' and would probably rather keep those 3-4 fat idiots happy than deal with a gym. So they're pushing you out. That'd be my gut feeling. It sure ain't right, but it's the weight carried (no pun intended) by those that work hard, train hard, and outshine the fat schleps of this world.
They probably whined about it. The manager just said "wait out the lease" and that's the end of it. I'd send a nice offer of $1.25 or $1.50 and if they decline that, they'll say no to everything - put your 100% into setting up a new place asap in that case. I've rented storage units for years due to numerous bands/studios... they let some wild shit go on, but clamp down on other things completely unfairly.
