RADON Mitigation – Compliance with SB-9 and the Ontario Building Code
|
Radon is a colourless, odourless, radioactive gas that occurs naturally as a result of the decay of radium. It is found to varying degrees as a component of soil gas in all regions of Canada and is known to enter dwelling units by infiltration into basements and crawl spaces. The presence of the decay products of Radon in sufficient quantity can lead to increased risk of lung cancer. Thus the importance of providing soil gas barriers below floor slabs in basements and crawl spaces as well as foundation walls that are in contact with the soil.
Health Canada recommends that Radon gas testing consist of a long-term test (minimum of 91 days) carried out by a Canadian National Radon Proficiency Program (C-NRPP) certified professional during the winter season. Where a test results has been conducted that exceeds 200 becquerels per cubic meter (Bq/m3) you will require a subfloor depressurization system to be installed to reduce the concentration levels below 200 Bq/m3. The owner/ builder will be responsible for the remediation work.
In compliance with the Radon mitigation measures, all new dwellings will be required to provide one (1) of the Soil Gas Control Systems listed below:
Option 1 – Soil Gas Barrier
a) provide a minimum 0.15mm (6mil) polyethylene sheet below the basement floor slab with joints lapped 300mm or joints sealed,
b) provide a bead of flexible sealant at the junction of the perimeter basement slab and wall,
c) seal around any floor penetrations such as drains, wastes or vents, and
d) provide dampproofing/ drainage membrane to the exterior foundation walls in contact with the soils
Option 2 – Depressurization System
a) provide dampproofing/ drainage membrane to the exterior foundation walls in contact with the soils and,
b) install an active subfloor depressurization system
Option 3 – Mandatory Radon Gas Testing
a) install a 4”(100mm) diameter pipe vertically through the basement/ crawl space floor slab such that the bottom opens up into the granular fill below the slab that is 6” (150mm) deep x 24” (600mm) in diameter and the upper end terminates above the slab which will permit the connection of depressurization equipment and is provided with a removable seal, and
b) Mandatory Radon gas testing is required - Where mandatory radon gas testing results come back over 200 Bq/m3, the owner/ builder will be responsible for remediation work and follow-up testing.

Required Permit Inspections |
During various stages of the project, an inspection may be required (as set out in the Building Code) to inspect the work.
Inspections do not happen automatically. It is the responsibility of the permit holder to notify the building department of the following inspections required by the building code:
- Storm, sanitary sewer connection, and water connection if applicable
- Footings, prior to pouring concrete
- Foundation, prior to backfilling
- Underground plumbing
- Soil Gas Membrane (Poly below the slab)
- Framing after electrical and plumbing have been installed
- Rough-in plumbing
- Insulation and vapour barrier
- Completion of construction to permit occupancy. Requires final plumbing & electrical certificates, potable water testing and septic approval, if applicable. Also may require certified lot grading if it is a requirement of a subdivision agreement at this stage
Final inspection is completed when the project is completed (which may, if applicable, include certified lot grading).
Plumbing Inspections |
As of January 1, 2020, the South Huron Building Department is responsible for processing plumbing applications. Please contact Building Services to obtain an application.
For assistance with plumbing applications started with the County of Huron prior to January 1, 2019, please contact the County Clerk:

Other permits and approvals that may be required |
Applicants are responsible for obtaining all necessary permits, inspections and approvals.
Electrical Safety Association Certificate of Acceptance |
Keep yourself and your family safe by making sure electrical work meets the Ontario Electrical Safety Code.
No matter how small the job, when you hire someone to do electrical work in your home, by law in Ontario they must be a Licensed Electrical Contractor. A Licensed Electrical Contractor will ensure the work is done properly, safely and legally with the necessary notifications to ESA. General handymen and other service providers cannot do electrical work unless they hold an ECRA/ESA licence number.
Once your electrical work has been reviewed and passed, ESA will issue a Certificate of Acceptance (or Certificate of Inspection for notifications created before July 6, 2020) to the person who filed the notification. It’s an important document for insurance purposes, resale and peace of mind.
If your contractor filed the notification, ask for a copy of the certificate for your records.

Regulation of Development |
Conservation Authorities are watershed-based resource management agencies, whose mandate includes a variety of roles and responsibilities in the land use planning and development process. Conservation Authorities responsibilities include ensuring development is not at risk from natural hazards such as flooding or erosion and they aim to protect and restore the ecological health and integrity of natural systems.
Ausable Bayfield Conservation Authority |
Before undertaking any filling, construction or altering of watercourses, contact Ausable Bayfield Conservation Authority staff to determine if you are in a 'regulated area'.
If applicable, Ausable Bayfield Conservation Authority staff will guide applicants through a permit process that involves gathering on-site information, survey work, and providing specific conditions to reduce risk to life and property, reduce potential social disruption and protect the environment from naturally occurring flooding and erosion.
