ELI5: Why do some areas allow you to use an Engine Break, while others do not?

Brake. My bad guys.

*brake*

Simply: because engine brakes are **LOUD**. 

People who own homes or businesses have a right, in common law jurisdictions, to the *quiet enjoyment of their property*. That means noise nuisances, such as loud stereos, bands playing, and trucks using engine brakes, are violating that right.
