Commerical Property being encroached upon by residential property

My family, E, owns a small piece of commerical property that is being impacted on one side by a residence built several years ago. A person who was looking to rent E's property and make some renovations, checked with zoning officials and was told that the residence had made E's lot a zero lot line property.

Have E's rights been violated by this residence? What would be the recourse in this situation?

Any comments would be appreciated.

zero lot line usually means

that you can build to the property boundries i.e. no setback
