So now I got a letter from an injury lawyer not in the LLC name  (the property owner by LLC ) but in the name of the HoA however the LLC address not the HoA address (the law firm seems confused it idk).

This is something I try to live by and teach my kids if I can - "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

Talk with these folks and have them address handling the above.  

I rarely see anyone address the underlying root cause of the issue.

Unfortunately, I’ve run into a major issue: I received a Stop Work Notice on my property in Covington, GA, because I didn’t have the proper permits for the renovations.I want to resolve this as quickly and smoothly as possible without jeopardizing the project.Can anyone offer advice or share their experience with:1.How to address the Stop Work Notice with the local authorities?

Consulting a tax professional now can help structure ownership and financing efficiently, ensuring you take full advantage of deductions, depreciation, and potential tax-saving strategies like 1031 exchanges in the future.This post does not create a CPA-Client relationship.

If we can't get an address to either party to mail a certified letter then a private investigator must be hired to locate them. 

It is located in some of the newest developments on the north side of Katy, TX 77493 (I am not sure if I can post a link to the Zillow page or provide the address because I don't own it yet).

I wonder what would have happened if you just used a friend/family members US mailing address.

FYI that the address listed as the mailing address for the city notices is still the property address.
