Standard of Practice

The ASHI Standard of Practice was an important tool in helping define home inspection as a recognized profession and gain traction within the real estate market. Refined over the years, the Standard remains an influential document across the industry and ASHI Members continue to adhere to the Standard today.

The document is divided into specific systems of a home and details the manner in which home inspectors should inspect each component. Not only does this help guide the inspector during the home inspection, but also ensure their client will receive a thorough and effective inspection. ASHI encourages everyone involved with the homebuying process to review the Standard of Practice to better understand the role of the home inspector.
