I had the same issue with the managment here at the park where I'm settled in for a while. It sucked not being able to work on my SC.
So I asked if it would fly to have a large tent structure in my space. Sure no problem.
They just don't want to see cars being worked on or up on stands etc.
Once I got the tent up and the car inside, then zipped up the street facing end.
I was free to do whatever inside the tent.
This a temporary set up but may be an option for you till something better comes along
My nomad garage.
There is room inside this 10' x 20' tent for the car and the engine/ trans just behind the car.
This may not be allowed in your situation, just bringing up another option .
I just finished some engine out projects, the nomad garage worked out very well in getting the management off my back, yet being able to carry on with my car projects.
