If you want your LLC to be respected for liability purposes, it should have an operating agreement, bank account (so an EIN) (this will also require disclosures to the bank on your identity), and for you to full respect it as a separate entity from yourself. 

Some things that might be a concern:1) Obviously have to make sure things are all permitted first2) I don't want the room to "feel" like an addition, so flooring has to be same level/standardized with the rest of the house3) Unlike the rest of the house that has an identically-shaped 2200sqft basement underneath, this added space will not have a basement directly underneath it -- I'm not sure if this poses major cons for some reason that I'm not aware of4) Especially given the lack of basement underneath, I have to make sure that the HVAC can still somehow be piped into this room#2 and #3 are probably my biggest concerns (#1 and #4 I can find out relatively easily)Any tips/thoughts or other experience would be greatly appreciated.

For illustration purposes if a tenant or passerby trips and becomes  hurt because of a premises liability event, if you discriminate against a tenant or buyer, fail to pay your contractor for work that was performed or any of the many fact patterns that could lead to claim exposure presents itself do you really believe your identity is going to stop a plaintiffs attorney from filing a claim, lien etc?

I am filling out the landlord identity registration form required in NJ, and I am not living in the same county as the property.

Would it be possible to file a mechanic's lien on your own property and would this be a way to discourage potential title thieves?
