A BIT OF HOME INSPECTION AND ASHI HISTORY

Home inspections were being performed in the mid 1950s, and by the early 1970s
were considered by many consumers to be essential to the real estate transaction. The
escalating demand was due to a growing desire by home buyers to learn about the
condition of a house prior to purchase. Meeting the expectations of consumers required
a unique discipline, distinct from construction, engineering, architecture, or municipal
building inspection.  As such, home inspection requires its own set of professional
guidelines and qualifications.

The American Society of Home Inspectors (ASHI) formed in 1976 and established the
ASHI Standards of Practice and Code of Ethics to help buyers and sellers make real
estate transaction decisions based on accurate, objective information.  As the oldest,
largest and highest profile organization of home inspectors in North America, ASHI
takes pride in its position of leadership. Its Membership works to build public
awareness of home inspection and to enhance the technical and ethical
performance of home inspectors.

Standards of Practice
The ASHI Standards of Practice guide home inspectors in the performance of their
inspections. Subject to regular review, the Standards of Practice reflect information
gained through surveys of conditions in the field and of the consumers’ interests and
concerns. Vigilance has elevated ASHI’s Standards of Practice so that today they are
the most widely-accepted home inspection guidelines in use and are recognized by
many government and professional groups as the definitive standards for professional
performance.

ASHI Membership
Selecting the right home inspector can be as important as finding the right home. ASHI
Members have performed no fewer than 250 fee-paid inspections in accordance with
the ASHI Standards of Practice. They have passed written examinations testing their
knowledge of residential construction, defect recognition, inspection techniques, and
report-writing, as well as ASHI’s Standards of Practice and Code of Ethics.
Membership in the American Society of Home Inspectors is well-earned and maintained
only through meeting requirements for continuing education.
