Legal Question in Business Law in California

Re: exclusivity laws

What does your lease say? That would probably be the only place for a restriction.

Re: exclusivity laws

"Legal"? Unless it is under the same landlord, and there is a lease provision protecting you from competition in the complex, all he is doing is pursuing the American dream, just like you. If your lease protects you, then deal with the landlord with your claim of breach of lease. Even if the lease doesn't specifically protect you, you have an argument that the landlord is allowing damage to your business. If either of those is the case, and you need legal help, feel free to contact me, if this is in SoCal.

Re: exclusivity laws

It is legal in the sense that it is not barred by any law. It might be a breach of your private contract with your landlord.
