I am not sure what an HOA is, but if it is a home owner's association, I know that in my state (Washington) the home owner's association rules and laws are actually stronger than state law... isn't that a hoot? In one case, a home owner was charged for repainting her home PLUS home owner association lawyer fees (about $11,000) because she painted her home "eggplant" and the association called for "neutral" colors. Interesting, eh?
So, does the home owners association charge the residents for electricity? Is this for the clubhouse or recreation area or something? I am not quite understanding who is getting billed for the electricity, but I do agree, this sounds like something a lawyer would need to handle. And something that they might be able to handle on contingency.
Best of luck in this.
