The owner of any property “owns” certain rights to use and enjoy the property. The owner may also give up some of those rights, either temporarily (e.g., if you rent out your house for a year, you give up the right to occupy and use it) or permanently (e.g., if you grant an easement to the electric company to run its lines through your land). Those rights don’t just disappear; they are transferred to someone else. In a CR, the landowner gives up specific development rights. Those rights must be held by someone — known as the “Grantee” or “holder.” Under Massachusetts law, grantees must be either a municipality or a qualified conservation organization.
