Thank you for contacting the Cherokee Co. UGA Extension Office and Master Gardeners concerning the ID of a bug in your neighbor's landscape.  This appears to be a wheel bug in one of it's nymph stages.  They can sometimes be confused with leaffooted bugs.  The wheel bug is common in our area and is one of our good predatory bugs.  It feeds on many of our pest insects that damage our plants.  Do not kill them if possible.  Please contact us if you have additional questions.
Mark Dady, UGA Master Gardener
