Which office handles septic permits in Greater Sudbury?

Greater Sudbury’s current Building Permits page specifically warns that properties with septic systems may require Public Health approval. It instructs applicants to contact Building Services at 705-674-4455 ext. 4278 to confirm the requirement.

Confirm the exact Part 8 authority before applying. New systems, replacements, major repairs, additions or changes that increase design flow can require permit review, site/soil information, design calculations and inspections before covering.

City-specific source review complete. The official route above identifies City of Greater Sudbury Building Services; Public Health approval may also be required. This does not establish onsite service, legal use, capacity, setbacks or approval for a particular lot. Check the exact address with the issuing office before relying on any estimate.
