Thank you for contacting the Property Maintenance Code Enforcement Division for the City of Richmond. Based on the information you provided we have determined that this is a neighbor to neighbor issue and it must be resolved as a civil matter. There is no code which relates to the height/overgrowth of bushes and or shrubs extending onto neighboring properties that do not block access to the public right of way.
