I'm telling you, my God, why can't ppl understand that. My neighbors speak all damn day, blinds opened and raised. Then when I pull up here they come out the house watching your every move. It's so damn annoying.
As long as you can get seay with it. Each jurisdiction has rules about how high you can have a fence/hedge without a permit. Usually, it's 6' in the back yard.
Wish I had a front yard but unfortunately my house is stuck to the sidewalk. I have to worry about trucks parking on the sidewalk where police could be involved or shady crackheads littering.
