How damages are usually measured

Just compensation is generally the fair market value of the property taken; in a partial taking it also covers the loss in value to the property that remains (severance damages), which some states offset by any benefit the project brings. Most cases come down to competing appraisals, and the gap between the condemning authority's offer and the owner's appraisal sets the range. Some states add interest, relocation costs or fee awards.

General background, not legal advice; the rules vary by state and by the documents in your deal.

What the calculator asks about

These are the facts it pulls from your description or documents for a commercial condemnation claim:

  • Condemning authority's initial offer
  • Does the dispute involve severance damages, access loss, or business value?
  • Is the owner challenging the taking itself?
  • Is this a pre-condemnation survey/access dispute?
  • Is a regulatory taking alleged?
  • Property's fair market value, if a regulatory taking is alleged
