The first sentence instructs readers that requirements for appraisals for Federal and federally-assisted programs or projects are located in 49 CFR part 24. These are the basic appraisal requirements for Federal and federally-assisted programs or projects. However, Agencies may enhance and expand on them, and there may be specific project or program legislation that references other appraisal requirements.

These appraisal requirements are necessarily designed to comply with the Uniform Act and other Federal eminent domain based appraisal requirements. They are also considered to be consistent with Standards Rules 1, 2, and 3 of the 2004 edition of the USPAP. Consistency with USPAP has been a feature of these appraisal requirements since the beginning of USPAP. This “consistent” relationship was more formally recognized in OMB Bulletin 92-06. While these requirements are considered consistent with USPAP, neither can supplant the other; their provisions are neither identical, nor interchangeable. Appraisals performed for Federal and federally-assisted real property acquisition must follow the requirements in this regulation. Compliance with any other appraisal requirements is not the purview of this regulation. An appraiser who is committed to working within the bounds of USPAP should recognize that compliance with both USPAP and these requirements may be achieved by using the Supplemental Standards Rule and the Jurisdictional Exception Rule of USPAP, where applicable.

The term “scope of work” defines the general parameters of the appraisal. It reflects the needs of the Agency and the requirements of Federal and federally-assisted program appraisal practice. It should be developed cooperatively by the assigned appraiser and an Agency official who is competent to both represent the Agency's needs and respect valid appraisal practice. The scope of work statement should include the purpose and/or function of the appraisal, a definition of the estate being appraised, and if it is fair market value, its applicable definition, and the assumptions and limiting conditions affecting the appraisal. It may include parameters for the data search and identification of the technology, including approaches to value, to be used to analyze the data. The scope of work should consider the specific requirements in 49 CFR 24.103(a)(2)(i) through (v) and address them as appropriate.
