What is the process when private real estate is needed for public projects? ‘Eminent domain’ is the label frequently used to describe that process, and its basis lies in the U.S. Constitution. All U.S. states, including Massachusetts, have their respective statutes regarding the state taking private real property. Although eminent domain’s application has expanded in recent decades, it is now a contentious issue in many regions. This latest controversy means appraisers currently have a critical role in the eminent domain field, working for private property owners and public entities. When eminent domain plays a part in an appraisal assignment, both the appraiser and client need to be aware of the unique requirements of this kind of practice.
