I lived in a trailer park once. It was the nicest most expensive “mobile home community” in the county and that was like an HOA on steroids.
They charged $20 extra per month if I had a cat (even if it never left the house) $35 for a dog. They gave me a hassle about rotating my tires in the driveway once. Went ballistic about the kids writing on the sidewalk with chalk that washed of with the next rain or a hose if I got sick of it. We couldn’t mow grass on a weekend but they would mow it for us during the week for $20 and then we had to contract with them to do it every week whether it needed it or not.
That was 15 years ago and I hate to think how bad they are now.
We had a lovely home in a park for 6 years. The owners would give permission for something and 2 months later change their minds. When the residents tried to form an association (to fight the owners monthly whims), the owners threatened to raise the rent from $250 a month to $700 a month if they continued. In my state, they could legally do it. We moved.
