Without using word sub lease

You want to circumvent the clause prohibiting sub letting.  What ever you do it can be a subletting, even if there is no clause the Rent Control Act prohibits subletting unless there is a positive concent from the building owner.  But you can circumvent the clause of subletting in the agreement or in the Act by entering into a contract of partnership or an agreement of agency, this is not fool proof, you have to be very careful while drafting.
