When to contact the Sudbury & District Health Unit?

Prior to the issuance of a Building Permit for your proposed project, approval from the Sudbury & District Health Unit (SDHU) pertaining to your septic system is required if you are:
  • Constructing a new building
  • Adding a bedroom, sleeping cabin, or washroom
  • Increasing the number of fixture units (sink, toilet, bathtub, shower, laundry, dishwasher, etc.), or
  • Increasing the total floor area of the building by 15 percent or more.
Please visit the SDHU website for further information. 
In order to ensure a smooth process for the issuance of your building permit, it is recommended that you obtain SDHU approval prior to submitting your building permit application.
