Renting storage units on a residential property

Hello, thanks for reading this post!

Id like to offer self storage units (pre-fabricated/standalone storage) to rent. I'd expect to have 5-20 units, would this be possible on a residential property?

Would I have to create a LLC or jump through some other legal/insurance hoops to be able to do this?

Does anyone have experience in renting out storage on their residential property? How do you do it? Was it worth it?

Again, thanks for taking the time to read this. All advice and suggestion are appreciated.
