USPAP 2018-2019 Edition
© The Appraisal Foundation
The Appraisal Standards Board (ASB) of The Appraisal Foundation develops, interprets, and amends the
Standards of Professional Appraisal Practice
(USPAP) on behalf of appraisers and users of appraisal services.
The 2018-2019 Edition of USPAP (2018-2019 USPAP) is effective January 1, 2018 through December 31, 2019.
USPAP has five sections: PREAMBLE, DEFINITIONS, Rules, Standards (including Standards Rules), and Statements
on Appraisal Standards (there are currently no active Statements). For convenience of reference, USPAP is
published with this Foreword and a Table of Contents. The publication also includes the Advisory Opinions and
Frequently Asked Questions (FAQs) as additional reference materials. These reference materials are forms of “Other
Communications” provided by the ASB for guidance only and are not part of USPAP.
It is important that individuals understand and adhere to changes that are adopted in each edition of USPAP. State
and federal regulatory authorities enforce the content of the current or applicable edition of USPAP.
HISTORY OF USPAP
These Standards are based on the original
Uniform Standards of Professional Appraisal Practice
1986–87 by the Ad Hoc Committee on Uniform Standards and copyrighted in 1987 by The Appraisal Foundation.
The effective date of the original Uniform Standards was April 27, 1987. Prior to the establishment of the ASB in
1989, USPAP had been adopted by major appraisal organizations in North America. USPAP represents the generally
accepted and recognized standards of appraisal practice in the United States.
At its organizational meeting on January 30, 1989, the Appraisal Standards Board unanimously approved and
adopted the original USPAP as the initial appraisal standards promulgated by the ASB. Portions of USPAP may be
amended, interpreted, supplemented, or retired by the ASB after exposure to the appraisal profession, users of
appraisal services, and the public in accordance with established rules of procedure.
CHANGES TO USPAP
Over the years, USPAP has evolved in response to changes in appraisal practice. The ASB has developed a
process for developing both Standards and guidance based, in part, on written comments submitted in response to
exposure drafts and oral testimony presented at public meetings.
The ASB issues guidance in the form of Advisory Opinions,
USPAP Frequently Asked Questions
(FAQ) and periodic
questions and responses “USPAP Q&A.” These communications do not establish new Standards or interpret
existing Standards and are not part of USPAP. They illustrate the applicability of Standards in specific situations
and offer advice from the ASB for the resolution of specific appraisal issues and problems. Please note that the
“See also FAQs” references shown in the margins of the Standards are in addition to already footnoted Advisory
Opinions (AOs); the location of these references do not place greater importance of USPAP FAQs over AOs, they
are simply another reference tool for the users of USPAP.
The USPAP Q&A is published periodically and available on The Appraisal Foundation website. These questions and
responses are compiled and published in the
USPAP Frequently Asked Questions
CONTACTING THE APPRAISAL STANDARDS BOARD
The ASB invites questions about USPAP, commentary on USPAP and proposed changes to USPAP from all interested
parties, including appraisers, state enforcement agencies, users of appraisal services, and the public.
If you have any comments, questions, or suggestions regarding USPAP, please contact the ASB.
