Report
Doing construction in a plot across the street from where I live and often park in front of my house. Not an issue. I totally get it. Until I came home from doing some errands and their truck was parked in my driveway in front of my garage so I couldnt pull into my driveway to get in. Seems unprofessional to park in a random persons driveway when youre not performing services for them. Wouldve liked to park in my garage and not down the street.
