I’m working on purchasing a park that has smaller lots than current regulations allow but has grandfathered status. The way I understand it, I can maintain grandfather status if I move in replacement homes that are the same size or smaller than the existing homes on the lot. If I want to install larger homes, I will have to reconfigure lots to meet current regulations. However, many of the vacant lots in the park have been vacant a long time. So long that it is unknown how big the original trailers were. How do I maintain my grandfather status without knowing the size of the original homes? Does the grandfather status even apply to the empty lots? Does anyone have any experience with this situation?
