On the other hand, we’ve had neighbors in detached homes with barking dogs and screaming children, and it makes DW unreasonably angry when people park their cars blocking the walk to our street. I’m usually oblivious and at peace with all of this annoyance until she comments on it.
Our townhouse is way quieter than my parents single family detached home. One of their neighbors lets his huge dog outside all day in the yard and is constantly barking. The windows on the side of their house let in a ton of noise. Their neighbors on the other side have 3 kids ages 5-9 who run around screaming from dawn till dusk all summer. A few doors down a guy has a Harley which you can hear for blocks. None of this is against city rules and there's no HOA so they just deal with it.
Our party walls are thick double stud walls with 4 layers of drywall that let in no sound from our neighbors. The kids all go play in the park a block away. There's nowhere to let your dog roam around unleashed and hence most people don't have dogs, or if they do, the dogs are smaller. Any obnoxious noises like revving a Harley would be immediately addresses by the HOA.
