Well, if one lives in Angel Grove, there's a whole district full of nothing but abandoned warehouses.
It might be cheep rent but its a high chance that a monster or a giant robot will destory them and their content and issuing complaints to the owners is impossible as the monsters owners tend to live on the moon, while the robot owners idenities are unknown to the public, so rent a warehouse if you dare, insurance companies likely have a clause saying damage caused by monsters or giant robots will result in non pay outs as they are classed as natural disasters and nobody can be held accountable!
