Overview
Home inspection is a critical element in helping consumers understand the condition of their home, but improper home inspections can lead to serious safety and financial risks for home buyers and increased pressure for home inspectors.
There can be a high degree of variation in home inspection practices across associations and jurisdictions. This makes it difficult for home inspectors to demonstrate that their services are thorough and add value to their customers, while customers face greater uncertainty as to whether their homes have been properly inspected. Part of why these issues exist is because there hasn't been a consistent set of requirements for a proper home inspection.
Introducing CSA A770 Home Inspection, a first-of-its kind standard developed through the collaboration of home inspectors, regulators, consumer agencies, and various technical specialists, that provides guidance on the minimum requirements for a proper home inspection.
CSA A770 establishes key systems and components that need to be inspected in and around the home, and outlines general inspection methods and minimum reporting requirements for inspectors to follow.
CSA A770 aims to help foster increased consistency in home inspection practices, leading to improved service quality and consumer protection.

Preface
This is the first edition of CAN/CSA-CSA A770, Home inspection.
This Standard specifies minimum requirements for a home inspection and provides information for performing an inspection on dwellings. These inspections are typically carried out on single family homes of any building configuration, often, although not necessarily, as part of a real estate transaction. This Standard provides important and practical requirements on what items are to be inspected as part of a home inspection. This Standard is not intended to provide comprehensive requirements for the methods to be used to perform a home inspection or specific conditions to look for in a home. This information would typically be available through a recognized home inspection training program.
This Standard has been developed through the collaboration of home inspectors, regulators, consumer agencies, and various technical specialists.
CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Service Alberta, British Columbia Office of Housing and Construction Standards, Manitoba Securities Commission, Ontario Ministry of Government and Consumer Services, and Financial and Consumer Affairs Authority of Saskatchewan.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

2) In this Standard, a condominium unit, strata unit, or co-op does not include portions of the building owned in common with other owners. These items may also be included in an inspection and employ this Standard by contractual agreement (see Annex A).
3) Although this Standard is for the inspection of the dwelling and associated property, some properties can include one or more ancillary buildings or structures. These may also be included in an inspection and employ this Standard by contractual agreement.
