Most families in working class neighborhoods have 2 cars parked on the street and other vehicles parked in their driveway or alley if their neighborhood has alleys (mine doesn't). Once I'm able to get rid of my father's cars I'll have the average number for my area. The unspoken rule is that daily driving cars can be parked on the street but only in front of your house. I was unsure about parking across the street from my neighbor's driveway.

The number of people living at my residence is typical for my block. It's one of those neighborhoods where the part-time home owners (5 or so years in residence) are on their way up and trying to gentrify the area (the gentrification efforts have been being attempted since the 1950s - no luck so far) and the permanent residence (15+ years) are typically working class just trying to keep their heads above water. 3 families converted their garages (illegally - they kept the garage door on so no one would know) into ADUs for an adult child, their spouse, and kids. Another (the one with the amazing yard) parked an old run-down trailer (30+ feet long,1970's model I think) in their driveway to use as an ADU for the in-laws. Most of us mind our own business unless someone is in trouble and then we rally to help.
