I've not got an HOA to deal with per-say... Just have the By-Law enforcement officer. She was nice about it and likely better looking than the HOA officers. I felt concerns about what was visible from the street were fair enough (we were mid renos)... what pissed me off was that they even complained about a small pile of grass clippings that were under a bush beside the 6' high fence in the BACK YARD. If the neighbor keeps it up, I'm going to require him to tear down that fence he went and built on my property, and build it on his own... it's likely less than a foot, but he's a prize and I just want to be able to enjoy my backyard without looking over my shoulder.
It's a shame I've started collecting old Bush-cutters, Weed-eaters, and Leaf blowers to maintain my yard to his 1/2" long lawn standards... something very appealing about an 8" carbide blade, spun by a solid shaft, at very high RPM, by a 1.8 hp, two stroke engine on the end of a 6.5' long pole.
This sounds like my father-in-law's house. It BACKS to a neighborhood, but the whole reason he built his house where he did was because it DOESN'T fall inside the neighborhood's jurisdiction and thus their HOA does not apply. This is an important consideration when you have 7 classic cars in various states of decay sitting in your driveway. A few years ago a neighbor decided to sell their house. They cut down a bunch of pine trees that had previously blocked their view of my father-in-law's house - decided that the cars (that were now visible to them for the first time in a decade) would detract from their home's value, so they called the county. The county told my father he had 2 weeks to get all of the cars registered and inspected in the state of Delware, otherwise they were derelict and he'd be fined $50 per car, per week, until they were gone. Over the next two weeks we got a 1951 Mercury V8 Flathead, a 66 6cyl Chevy Bel Air, a 1994 Ford Rollback, a 1967 Chevy Van, a 1965 Ford Van, and a 1973 Plymouth Roadrunner running, through inspection, tagged in the state of Delaware, and parked right back where they had been before the complaint was filed. The only one we didn't finished with the 1931 Ford AA Dump truck which he dropped at a buddy's place for re-wiring. The county inspector returned and couldn't believe his eyes - the inspector had really hated making the call and had a really good laugh about it.
Every time my father in law saw the realtor at the neighbors' house giving a tour, he'd fire up one of his louder cars (70 Coronet R/T, 36 Dodge Pickup Rat Rod, 71 Mustang) and do a nice long burnout down the driveway after revving them repeatedly to "warm them up."
One last gripe on HOA's then we can return to our regularly scheduled programming. My parents' neighborhood has one and the neighbors there are the worse. A neighbor had their driveway repaved, and, when finished, the fresh pavement had been compacted to extend/overlap 1" into the road. Someone called the HOA and complained. The HOA called the county. When the county came to check out the "Egregious driveway" they saw the pile of sticks my mom (avid gardener) had left in the side yard, and fined my parents for "yard litter."
