I lived in a town house for awhile, years ago (I was still a bachelor).
We had a home owners association.
Rudy, a retired elderly man, was the president.
I had an approximate 6 X 6 foot front lawn (as did everyone else) and was responsible for maintaining it.
It was a "homeowners rule" to keep the grass less than 4 inches tall.
The association fees took care of all the common areas.
I didn't own a lawn mower.
I used a weed waker but could have just used a pair of scissors (if I had the time).
At one of the homeowners meetings Rudy handed out photographs.
He had gone around to everyones front lawns (the 6 X 6 lawns), placed a ruler in the ground, and gotten down on the ground to take Polaroids to report (embarrass) on folks whose grass was taller than 4 inches.
I was guilty.
Mine checked in at 4 and 1/4 inches.
Thanks Rudy (part 1).
