You must obtain a building permit from the City for constructing or altering an onsite sewage system with a daily capacity of 10,000 litres or less.
Permits for systems over 10,000 litres per day are issued through the Ministry of Environment, Conservation and Parks. This permit application is reviewed for compliance with the Ontario Building Code, local zoning bylaws, and the Cataraqui Region Conservation Authority regulations.
Constructing or altering a sewage system without a permit is illegal and subject to penalties, including a non-refundable administrative surcharge fee as per the City of Kingston Building Bylaw.

Plumbing in conjunction with another building permit
When applying for a new home, addition, or alteration building permit, there is no need for a separate sewage system record as we will review the sewage system in conjunction with the building permit. Plans and specifications should be uploaded to the building permit record. Additional fees for septic review may be charged.
When you want to make changes or add to a building that already exists, we will check if the sewage system can handle the new fixtures being added. You need to fill out an application for review of performance level of existing on-site sewage system and upload it to your DASH record.
