I contacted code enforcement many times it only provides a tempoary solution.

Not all violations are dead serious, advertising to make loans by an unregistered lender is a violation, but that is enforced on a random basis, find someone to make an example of pretty much. 

I'm new to the whole real estate game and have no ideas as to where I start.

A game room?

I am no expert and have only been in the game a little while, but here's how I find mine. 

Everything under one LLC is fair game for creditors of that LLC.  

Point is, not everyone needs an entity to start out with, at some point, like in Rod's case, having assets and equity can make you a target and forming an entity will be prudent later on for those who stay in the game and succeed.

People looking for deals.Also, usually the code enforcement folks will call.

However, I believe it is always a good idea to include anything and everything in the lease - so long as it is enforceable and protects your interests.

Running a business is a whole other ball game.
