How to Become A Private Inspector of Onsite Sewage Systems (Home Inspector)

How to Become A Private Inspector of Onsite Sewage Systems (Home Inspector)

To become a private inspector of onsite sewage systems, you will need the required accreditation to become a Home Inspector, which usually involves a community college program. Check out the Ontario Association of Home Inspectors (OAHI) for more information about this industry.

If you would like to specialize in onsite sewage systems, or increase your knowledge about them, we recommend following these steps (which are the same steps required to become a qualified building official):

Step 1: Obtain Your Building Code Identification Number (BCIN)

To register for your BCIN which is a personal identification number, visit the MMAH website. You will be redirected to the QuARTS system to complete the registration. QuARTS is a public registry of all Ontario Building Code (OBC) practitioners and BCIN holders. By obtaining your BCIN you will be identified on the QuARTS system by MMAH as such. All registered practitioners are listed in the QuARTS Public Search Registry.

Step 2: Prepare for the Ontario Building Code (OBC) On-site Sewage Systems 2012 exam and the General Legal/Process 2012 exam (2 exams)

The two exams that are recommended are: On-site Sewage Systems 2012 (Part 8 of the OBC) and General Legal/Process 2012. There are courses available to prepare you to challenge the two exams. Part 8 preparation (On-site Sewage Systems 2012) and legal process courses are not a mandatory step in the process; however, these are recommended. These courses generally run for 5 days each and will address the fundamentals of sewage system functionality, basic design considerations and Division B, Part 8 of the Ontario Building Code, and the legal processes surrounding building inspections. An example of the syllabus for the exam can be found on the Government of Ontario’s website. There are a number of course providers who deliver both on-line and in-person classes. OOWA is proud to partner with some of these course providers and maintains a list of available courses in our Events Calendar as well as our monthly On-Track Bulletin – one of many OOWA Membership benefits.

If you would like to conduct other types of inspections (plumbing, HVAC, etc.), then it is recommended to take and pass those associated Ministry of Municipal Affairs and Housing (MMAH) exams.

Step 3: Book Your Exam Dates and Locations

Humber College administers all Ontario Building Code exams. Visit their website to see the exam fees, an exam schedule and register for your exams. Note that exams can only be booked a minimum of 21 days in advance. Exams are conducted on-line and can be written at home, the office, or at a nearby college. Be sure your computer has the required audio and video capabilities to complete the exams. The QuARTS system will send you an email notification when your exam results are available.

Suggested Step 4: Join the Industry Association

The Ontario Onsite Wastewater Association advocates to the Government on behalf of professionals in the onsite wastewater industry and represents our members with our organizational partners. Because OOWA sits at tables where individuals cannot, there is power in our numbers. As our membership grows, our ability to improve the industry for our members increases. Show your clients that you are an engaged and current professional by becoming a member of the Association. Set yourself apart from your competitors. Join us.
