An on-site sewage (septic) system permit is required for the installation, alteration or repair of any part of a septic system. If a building is served by a septic system and construction, alterations or a change of use of the building is proposed, then a septic system permit may also be required.
Whether you are constructing new or adding bedrooms, plumbing fixtures, floor area or changing a use of a building, you will be required to building a new septic system, add on to the existing septic system or confirm that the existing septic system is sized appropriately, contact the Building Division at email@example.com or 905-476-4301
- Lake Simcoe Region Conservation Authority: Approval from the LSRCA is needed if you are constructing in their regulated area. LSRCA regulations may restrict construction. Consult LSRCA's mapping tool to see if your property is regulated or call 905-895-1281
