In many rural or semi-rural communities across Ontario, residential properties are often not connected to municipal wastewater systems. Instead, these homes rely on private septic systems, which must be properly installed, maintained, and inspected to ensure long-term functionality and environmental safety. For prospective homebuyers considering properties with septic systems, conducting a thorough inspection prior to purchase is critical to avoiding legal complications, health hazards, or costly repairs.
Understanding the Legal Framework and Responsibility
Under Ontario's Building Code Act, 1992 and associated regulations, all on-site sewage systems with a design capacity of 10,000 litres per day or less fall under the jurisdiction of the local municipality or conservation authority. These systems must comply with strict guidelines regarding installation, distance from wells and watercourses, and ongoing operation. Upon the resale of a property with a septic system, the seller may be required to provide documentation regarding its maintenance history or permits, depending on the jurisdiction. Buyers are therefore advised to seek confirmation that the system is properly permitted and in compliance with applicable standards.
Key Components to Inspect During the Due Diligence Period
Before finalizing an Agreement of Purchase and Sale, the prospective buyer should retain a certified septic system inspector. This professional assessment should focus on:
- Location and Accessibility:
Confirm the location of the tank and drainage field. Ensure that access for maintenance trucks is possible and that no permanent structures are built over critical components.
- Age and Type of System:
Determine the system’s age and whether it is a conventional gravity-fed system, a pumped system, or an advanced tertiary treatment unit. Older systems may no longer comply with code or may be near the end of their serviceable life.
- Tanks and Lids:
Inspect the tank itself for cracks, rust, and structural integrity. Improper or broken lids can present safety hazards and allow surface water infiltration, compromising function.
- Leaching Bed (Drain Field):
The drain field should be examined for signs of hydraulic overload, pooling effluent, or odours. Vegetation over the area may also indicate saturation or failure.
- Maintenance Records and Pump-Out Schedule:
Request maintenance records and confirmation of routine pump-outs, typically every 3–5 years. Lack of maintenance documentation may indicate neglect, increasing the risk of system failure.
- Well Water Testing (if applicable):
If the property also relies on a private well, water quality should be tested to ensure that there is no bacterial contamination caused by a failing septic system.
Risks of Skipping Septic Inspections
Failing to inspect the septic system prior to closing can expose the buyer to environmental liabilities, repair costs, or even municipal orders to replace or decommission unsafe systems. A malfunctioning septic system may also negatively impact the property's future marketability, especially in competitive regions such as Waterloo and Kitchener, where many buyers prioritize environmentally sound infrastructure.
In some cases, financing or insurance providers may request inspection documentation before issuing approval, particularly in older homes or rural settings. A formal inspection report can thus play a critical role not only in negotiations but also in completing the transaction.
