I have a rental property and I believe the HOA is overstepping it's boundaries with my tenants. I received a letter stating that there car smells(exhaust) and is too loud. They listed some sections and parts that they were violating. I've talked with the tenants and the car is an '87 Mustang with passes emissions, and has stock mufflers. We all know that V8 mustangs are loud anyways. The letter states that if they don't fix the problem that they will have to pay $25 per day until they do. How do they fix the problem and does the HOA have the right to inforce this?
