In my experience a home inspector is demonstrating negligence to say "it's OK" on an inspection. 

But, if you aren't being a negligent slumlord, you should be okay. 

More then one person can call CPS because they may not respond to just one call for negligence. 

It's poorly managed and I fear an assessment is imminent because of negligence.

Any repairs that were caused by tenant's actions or negligence are paid by the tenant entirely.

If your negligence is great enough, and the plaintiff has a good enough attorney, they will likely be able to "pierce" that veil and come after the owner personally, which would ultimately put any other assets (the other LLC's) on the table.

While working out arrangements with the tenant for repairs, they have become very unwilling to work with us and is trying to put as much of the cost on us even though the fire was caused by gross negligence on the tenants part.

You will also likely need street/sidewalk closure permits at different points in the jobUtility Taps- Water, Sprinkler, Sewer, Power, Gas, Cable (this is likely negligible as the cable company should do it for you)Excavation/Foundation- Are there buildings on either side?

Was it negligence (foreign objects put down the drain) or just buildup over time.  

Either way, you were not negligent and it is not your personal property so you are not responsible.
