I'm working on a major project for and estate taxation purposes. The estate has all sorts of oddball properties. One parcel is odd shaped, the majority of which is environmentally sensitive. A portion, however, is cleared, level, has a lawn, and is outside of the environmentally sensitive areas. The setback areas overlap, which means it isn't buildable without having relief granted from the Zoning Board of Appeals (ZBA). I was told that the property wasn't buildable. So, as part of my normal course of business, I research the documents for the property. Lo and behold, a variance has been granted by the ZBA, allowing setback relief and allowing a home and in-ground pool (common amenity) to be constructed on the property. A follow-up call to someone in the know at the ZBA confirms that the variance runs with the land. Had I not been the permit police, my value conclusion would have been 25% or less of the actual fair market value.
