But what is their reasoning for this?

In some areas, tall grass becomes a habitat for snakes, which can be problematic for children.

For most areas, it's aesthetic.

Here in the south-east, a short lawn will have no mosquitoes but a grassy area will have plenty (as in you'll get 20-30 bites in one evening outdoors), so that's a strong motivation.

On the other hand, snakes eating all the rats would be good for children. Rats are reservoirs for many human diseases, but the think on the snakes!! is a common alibi for forcing your neighborg not to having shrubs, roses, grass, climbers, rocks, ponds and everything that would make your own garden look duller by comparison.

I think it's about the looks. Everything needs to be tidy and clean.

What if someone wants tidy, clean and paved, or tidy, clean with lots of interesting shrubs and trees?

Simply a case of no, a lawn it must be?

HOA's and HOA bylaws are normally mandated and created by the bank doing the construction loan. They do this to protect the value of the property while they hold interest in the remaining lots. The mortgage industry also loves this since in the end they may be stuck with a property if there is a default.

Drop in property value comes to mind if there's an adjacent stretch of untamed wild.
