In some cases, home owners may need to seek approval from local officials before making significant changes to their properties. In a May 5, 2017 opinion, the Massachusetts Land Court reviewed a zoning board decision rejecting a building permit application filed by the plaintiff. The key question for the court was whether a vacant, dimensionally non-conforming parcel of land merged for zoning purposes with an adjacent property, therefore rendering the vacant parcel separately unbuildable.
The vacant parcel at issue was held in trust, with the plaintiff and her mother as trustees. The plaintiff also owned, in her individual name, an adjacent property with an existing house. The plaintiff filed a building permit application to construct a single-family home on the vacant parcel, which was denied on the ground that it was under common control with the adjacent parcel.
In Massachusetts, the doctrine of merger provides that adjacent lots in common ownership will normally be treated as a single lot for zoning purposes in order to minimize non-conformities. Once merger occurs, it cannot be undone. In other words, a person owning adjoining lots may not artificially divide them in order to restore old record boundaries and obtain a grandfather non-conforming exemption. Instead, to preserve the grandfather non-conforming exemption, the lots must retain their separate identity.
