Taken from the SLP website, "Frequent loud barking, howling or yelping is prohibited"...
I'm awoken just about every morning by just this - frequent loud barking - and it lasts for up to an hour or more. It would be wonderful if pet owners in the neighborhood were respecful of their neighbors and didn't leave their dogs outside to bark in the early morning hours. I don't mow my lawn first thing in the morning when I wake up or play loud music. Please return the kindness and let your dog bark all he wants after the rest of the neighborhood has had their coffee.
Thanks.
