Appraisal Standards: USPAP and the Yellow Book

Appraisal basics

The standards a condemnation appraisal is written to

Two standards matter. USPAP sets the professional obligations of every certified appraiser in the United States. The Yellow Book supplements them where federal money is involved, and its requirements are stricter.

The two standards

What each one governs

USPAP

The Uniform Standards of Professional Appraisal Practice, issued by the Appraisal Standards Board. It is enforced through state licensing, so a breach is a disciplinary matter, not merely a professional embarrassment. It governs competency, independence, scope of work, the content of reports and record keeping. Every certified appraisal in this field complies with it or should.

The Yellow Book

The Uniform Appraisal Standards for Federal Land Acquisitions, prepared by the Interagency Land Acquisition Conference. It applies to acquisitions by federal agencies and to federally assisted acquisitions where the funding agency requires it. It is more prescriptive than USPAP about the larger parcel, the project influence rule and what evidence may support highest and best use.

Why it matters to an owner

Standards are the ground for a challenge

An owner who disagrees with an appraisal has two kinds of argument available. The first is a difference of opinion: the appraiser chose these comparables, I would have chosen those. Differences of opinion are legitimate but weak, because the appraiser is entitled to a professional judgement.

The second is a standards argument: the appraisal did not do what the applicable standard requires. It failed to analyse the remainder separately. It used sales affected by the project. It stated a highest and best use without supporting evidence. These arguments are stronger because they do not ask anyone to prefer one opinion to another.

This is the practical value of knowing which standard applies. Ask early whether federal funds are involved in the project. If they are, the Yellow Book almost certainly governs, and its requirements give more to hold the report against.

Questions about standards

How do I find out whether the Yellow Book applies

Ask the agency whether the project receives federal funding and whether the acquisition is being conducted under the Uniform Relocation Act. Highway, transit, airport and many utility and flood control projects commonly are.

Is a USPAP breach useful in a compensation dispute

It can be. It goes to the weight a court or commission gives the report and, in clear cases, to whether the appraiser should be permitted to testify at all. It is raised through an appraisal review rather than asserted by the owner directly.

Does my own appraiser have to follow USPAP

Yes, if the appraiser is state certified. An appraisal prepared outside USPAP by someone not certified will carry very little weight and may be excluded.
