OAHI - Ontario’s Authority For Home Inspectors - The Law Since 1994 (Bill Pr158)

About the OAHI

Through education and advocacy the Ontario Association of Home Inspectors cultivates a thriving home inspection industry based on the highest standards of professional development and ethical standards. In doing so, OAHI cultivates the ‘gold standard’ for home inspectors among consumers and the government. OAHI is the only provincially recognized body of home inspectors by The Ontario Association of Home Inspectors Act, 1994. OAHI is a not-for-profit association.

OAHI member inspectors see homes differently.

"I have now been a home inspector and a member of OAHI for 15 years. I have always stayed with OAHI as it’s the only organization that I have ever had referrals from." Dave Leebody of Northern Healthy Homes Inc in Sudbury


"I want to thank the OAHI and everyone involved, for the continued support and professionalism which I have experienced, since I became a member of the OAHI, back in 2003. The past 16 years have been a great experience in my life, and I will definitely miss being a member and attending the various functions, meetings, and educational seminars." A past OAHI member who relocated to another province.

The Ontario Association of Home Inspectors Act, 1994 received Royal Assent on Dec. 9, 1994 in the Ontario legislature.

Considerable experience, education/training, field work and expertise are required for successful performance in this profession. No single source of information is sufficient to launch a competent practice in this field. It is a combination of all.

First, there is no other profession or line of work that would fully prepare you to become a home inspector. Although construction related fields require an understanding of how new homes are built, they rarely deal with the extended use and age related deterioration of components that the home inspector encounters daily. You will need extensive detailed knowledge in many areas such as electrical and plumbing systems, heating and cooling systems, roofing, attic structures, as well as interior components and structures.

You will also require knowledge of components that are obsolete yet still in service. No single course, nor even a collection of courses can prepare you for all of the significant conditions that occur in the field. The ability to recognize a condition or defect that may be a problem comes in part from experience with "what can go wrong".

OAHI meetings, workshops, education conferences, and webinars, are also instrumental in producing well qualified professional inspectors. Inspectors who lack exposure to more disciplined and formal training and rely on their "experience" only are at risk for having difficulty distinguishing between arm-waving opinions and well researched authoritative sources of information. This is a critical distinction if you are to practice as a qualified professional, rather than simply as a generic business operator.

The OAHI has recognized that and requires that certain specific courses are mandatory baseline requirements to ensure that its members are above the crowd and true professionals.

The best credential you can have in the home inspection profession is membership in the OAHI. Its members are widely recognized. Anyone interested in the business should become an Applicant or Student member as early as possible. This can enhance your competence and professionalism. Remember, your customer's expectations will be very high. In order to meet those expectations, you will need to be very good and very careful. Sharing ideas and experiences with others in the business can be extremely valuable to the survival of your business. Note: The courses can be done in any order; if you are not sure that this is the field for you... new home inspectors have indicated that by taking the weekend Defect Recognition Course first was a valuable tool in their decision. At this course, you meet those in the same situation as yourself, as well as veteran Inspectors, and knowledgeable instructors.
