A septic system is a private waste disposal and treatment system. If your property doesn't connect to the municipal sewer system, you may need to install a septic system on your property.
You'll need to apply for a septic permit to:
- add a septic system to your property (for either a new or replacement system)
- repair or upgrade an existing system
- undertake projects that may affect an existing system

Septic change of use application
A septic change of use application is needed when proposed construction or alterations to your home may reduce the ability of your septic system to perform as originally designed.
If one or a combination of the following applies to your project, it could require changes to your septic system:
- adding more bedrooms to your house
- adding plumbing fixtures (e.g., a new bathroom)
- any planned addition that is more than 15 percent of the original finished area of your home when the septic system was installed
- changes in occupancy (e.g., from a residential use to a business use)
- any changes that could result in overloading the existing septic system.
Complete the septic change of use application
If any of the above apply to your building project, you must submit a completed septic change of use application to the Building department for review and approval before starting your project.

Septic inspections
You will need to get an inspection once the permit is issued and before the septic is covered. Additional inspections may be required depending on the plans or project. Please refer to your permit for details on required inspections.
When booking your inspection, please note:
- we require at least two days’ notice
- inspections are not conducted on weekends or statutory holidays
- we cannot book specific times, such as morning or afternoon inspections
Inspectors cover over 500 square kilometres which can include island access or special investigations. Please include any special instructions related to your request when completing the form, such as that your property is water-access only, or how to enter the property. Inspections are arranged to be as efficient as possible to complete the inspections requested for that day.
Building Inspection Request form
Failure to acquire permits and complete the required inspections per the issued permit and the Ontario Building Code can result in fines or penalties. You may even be required to remove or demolish unauthorized construction projects or septic systems.
Compliance letters
Compliance letters are typically requested during the sale of a property or a mortgage renewal. They provide information regarding open or closed building permits, septic files, non-compliance or non-conformance, by-law infractions, etc. To request a compliance letter visit our Zoning page.
