You scope a large commercial loss, you write it accurately, and the settlement comes back well short of the work the building actually needs. The owner is frustrated, the project stalls, and the easy move is to walk away from a job that no longer pencils. Many shops do exactly that, and a lot of fair, real reconstruction work dies in that stalemate.

There may be a mechanism in the owner's commercial property policy that exists for precisely this situation, and plenty of contractors have never heard of it. Appraisal is a built-in dispute-resolution process that resolves disagreements over the amount of a loss without a lawsuit and without abandoning the project. You, the contractor, cannot invoke it. But understanding how it works lets you help a stuck owner see a path forward instead of writing off the job.

What the appraisal clause is, and what it is not

Whether the owner's policy has an appraisal clause is set by that policy, so read it, and whether either side can reject an appraisal demand depends on the state, as the International Risk Management Institute (IRMI) definition notes, so look up yours. It is a standard provision designed to resolve one specific kind of disagreement: a dispute over the amount of the loss.

Keep the two apart: appraisal settles how much the loss is worth. It does not settle whether the loss is covered.

• Amount disputes (covered by appraisal): the policyholder and the carrier agree the loss is covered, but disagree on the dollar value. The carrier says the roof and two floors total $180,000; the policyholder's documentation says $260,000.
• Coverage disputes (not covered by appraisal): the disagreement is about whether the policy covers the cause of loss at all. That is a coverage question, and whether appraisal can reach it is set by the policy wording and your state's case law.

So appraisal is the right tool when everyone agrees there is a covered loss but they are far apart on its value. That is a very common situation on large, complex commercial scopes, where the difference between two good-faith estimates can be six figures.

How the appraisal process works

The mechanics are spelled out in the policy, and they are more orderly than plenty of owners expect:

• Each side names an appraiser. The policyholder selects one competent and impartial appraiser (some policies and state standard forms say "disinterested"); the carrier selects one. "Impartial" or "disinterested" is the load-bearing legal term: the appraiser must know how to value the loss and must have no financial stake in the outcome. An appraiser is not supposed to be an advocate, though each side naturally names someone who understands their position.
• The two appraisers try to agree. They review the loss and attempt to settle on the amount between themselves. If they agree, that agreed amount becomes the award and the process is over.
• A neutral umpire settles what they cannot. Under the standard Insurance Services Office (ISO) commercial property wording, the two appraisers choose a third party, the umpire, at the start; some policies wait until the appraisers deadlock. Either way, the appraisers submit their differences to the umpire. If they cannot agree on an umpire, the policy wording sets what happens next, such as asking a court to appoint one, so read it.
• Any two of the three agree, and it is binding. The award is set when any two of the three (two appraisers, or one appraiser plus the umpire) agree on the amount. Under the standard wording, that agreement is binding on both the policyholder and the carrier.
