Well done to all the emergency service personnel involved!
I wonder if a stateside Dwellar would answer a question, please?
As I understand it, HOA stands for Home Owners Association.
The only context in which I have seen reference to an HOA is in an apartment block where it manages and maintains the common parts of the building and grounds.
As far as I can make out from the article, the house mentioned is a private self-contained dwelling.
In this context, where does the HOA come into it?
Ta!
