Unknown. Since Parkgate, Burnell, Duvall, and Jennings are all public streets and owned by the Town of Leesburg, they have very few parking restrictions. As long as a vehicle has an up-to-date inspection and registration, it can be legally parked on any public street. As to the WHY, one could speculate a number of things: 1 – a residence may have 4-5 related adults who physically work outside the home, 2 – a resident likes to have lots of cars, 3 – it is more convenient than other parking alternatives, or 4 – commercial vehicles are not to be stored on common HOA property or permitted to be parked on a private lot/driveway. The list could go on.
