Funny thing about HOA's are that they are home owners in the same subdivision. I am the president of another HOA located close to Sundance. The problem with the HOA is twofold; first, the HOA board is not the heavy here, the property management company the HOA employs is the enforcement. The HOA board then decides how "over the top" the management company should be on enforcement. In many cases, the HOA board is so out of touch with their community that they allow the management company to completely control the property. When I was elected to the HOA in my subdivision, the property management company was aggressive, rude and used intimidation to "shakedown" the owners. I am happy to say the two years later, we have cleaned house on the HOA board, and flipped the paradigm on the property management company. The management company is paid by the HOA, so they are supposed to take direction from the HOA board, which is elected by the community. The owners are ultimately in charge of their own property, and can dismiss the current HOA board with 2/3 majority vote from the owners. If the management company challenges the decisions of the HOA board they can be fired, and their contract voided due to their own breech.
My suggestion is to gather your community together and regain control over your HOA. Go to the meetings and demand answers from the board. If they cannot provide the answers and change needed, then the board needs to be removed and/or replaced by competent owners that will force the change. Many of the HOA's were hurt financially during the lapse in the economy and use this as an excuse to extract more monies from their residents under the guise of fines or penalties. However, they must prove that the violation is legitimate and provide proof in the form of pictures and documentation. If they cannot, the fine is void. Secondly, there is procedure that must be followed to add a lien to your home, and many courts are not supporting these liens from HOA's.
Sundance is a huge community and encompasses quite a bit more than just the local neighborhoods, so the processes may vary a little, however, they cannot fine a person for a car parked in front of your home that is not yours. The community does not own the streets, the city does. You should be able to take those fines to the justice court and have them all dismissed. Secondly, if the car is continually in front the home, the owner of the home can call the city and have it removed at the car owners expense. Unless there is a regulation that Sundance negotiated with the city on overnight street parking, the HOA or management company has no control over public roads.
Buckeye is a great place to live, do not let the HOA's scare you away, just do your due diligence and investigate your community before you move in. Check with residents that live there, and don't limit yourself to one subdivision. Buckeye is a big place and there are plenty of options out there.
