202 National Standards of Practice

The National Standards of Practice are a set of guidelines for home and property inspectors to follow in the performance of their inspections. They are the most widely accepted Canadian home inspection guidelines in use, and address all the home’s major systems and components. The National Standards of Practice and Code of Ethics are recognized by many related professionals as the definitive Standards for professional performance in the industry.

These National Standards of Practice are being published to inform the public on the nature and scope of visual building inspections performed by home and property inspectors who are members of the Canadian Association of Home and Property Inspectors (CAHPI).

The purpose of the National Standards of Practice is to provide guidelines for home and property inspectors regarding both the inspection itself and the drafting of the inspection report, and to define certain terms relating to the performance of home inspections to ensure consistent interpretation.

To ensure better public protection, home and property inspectors who are members of CAHPI should strive to meet these Standards and abide by the appropriate provincial/regional CAHPI Code of Ethics.

These Standards take into account that a visual inspection of a building does not constitute an evaluation or a verification of compliance with building codes, Standards or regulations governing the construction industry or the health and safety industry, or Standards and regulations governing insurability.

Any terms not defined in these Standards shall have the meaning commonly assigned to it by the various trades and professions, according to context.

1. INTRODUCTION

1.1 The Canadian Association of Home and Property Inspectors (CAHPI) is a not-for-profit association whose members include the following seven provincial/regional organizations: CAHPI-British Columbia., CAHPI-Alberta, CAHPI-Saskatchewan, CAHPI-Manitoba, OAHI (Ontario), AIBQ (Quebec), and CAHPI-Atlantic. CAHPI strives to promote excellence within the profession and continual improvement of inspection services to the public.

2. PURPOSE AND SCOPE

2.1 The purpose of these National Standards
of Practice is to establish professional and uniform Standards for private, fee-paid home inspectors who are members of one of the provincial/regional organizations of CAHPI. Home Inspections performed to these National Standards of Practice are intended to provide information regarding the condition of the systems and components of the building as inspected at the time of the Home Inspection. This does NOT include building code inspections.

These National Standards of Practice enable the building being inspected to be compared with
a building that was constructed in accordance with the generally accepted practices at the time of construction, and which has been adequately maintained such that there is no significant loss of
functionality.

It follows that the building may not be in compliance with current building codes, standards and regulations that are applicable at the time of inspection.

These National Standards of Practice apply to inspections of part or all of a building for the following building types:

• single-family dwelling, detached, semi- detached or row house

• multi unit residential building
• residential building held in divided or

undivided co ownership
• residential building occupied in part for

a residential occupancy and in part for a commercial occupancy, as long as the latter use does not exceed 40% of the building’s total area, excluding the basement.

2.2 The Inspector shall:

A. inspect:

1. readily accessible, visually observable installed systems, and components of buildings listed in these National Standards of Practice.

B. report:

1. on those systems and components installed on the building inspected which, in the professional opinion or judgement of the inspector, have a significant deficiency or are unsafe or are near the end of their service lives.

2. a reason why, if not self-evident, the system or component has a significant deficiency or is unsafe or is near the end of its service life.

3. the inspector’s recommendations to correct or monitor the reported deficiency.

4. on any systems and components designated for inspection in these National Standards of Practice which were present at the time of the Home Inspection but were not inspected and a reason they were not inspected.

2.3 These National Standards of Practice are not intended to limit inspectors from:

A. including other inspection services in addition to those required by these National Standards of Practice provided the inspector is appropriately qualified and willing to do so.

B. excluding systems and components from the inspection if requested by the client or as dictated by circumstances at the time of the inspection.

3. GENERAL LIMITATIONS AND EXCLUSIONS

3.1 General limitations:

A. Inspections performed in accordance with these National Standards of Practice

1. are not technically exhaustive.
