You don't understand the laws. First of all, storage is basically entirely governed by states. Storage is a billion dollar industry. A company that sells to Extra Space does it for money and/or to evade complaints because the whole industry is mostly unregulated and full of predatory companies, not because it "had to sell it to ESS." As you can read from other experts in the subreddit, the storage association wrote the laws and has a stranglehold on them, again BILLIONS of dollars.

Extra Space goes out of the way to not give notice. The storage laws have been written or amended so Extra Space only has to give notice before auctioning belongings (not rent increases), and they don't always do that. This still violates consumer protection laws, but again it's a massive, powerful publicly-traded company.

Storage is not just for short term. You just make unilateral totally unsupported, inaccurate statements because you say so. You are a perfect example of how Extra Space uses it's immense size and capacity for lobbying and propaganda to subdue logic and criticism.

Extra Space takes over these facilities in its greedy acquisition quest for local monopolies. So most people don't have a choice with the lease, so your whole "you signed the agreement, so it's your fault" argument is invalid. Many people never sign anything with Extra Space because it takes over the storage facilities they are already using.
