Enbridge Gas Distribution must conduct an initial inspection of all gas appliances before homeowner occupancy (Ontario Regulation 212/01). If the inspection has not taken place at the time the account is transferred from the builder to the home buyer, the gas supply may be terminated until the inspections can be completed.


When is a home ready for initial installation inspections?

Initial installation inspections shall be conducted when the construction and finishing stages are completed and all natural gas appliances are installed, in accordance with codes and regulations. This includes all appliances intended to be installed at time of occupancy.

Minimum site requirements for initial installation inspections:

  • All natural gas equipment intended to be installed are ready for activation and inspection.1
  • Building is substantially completed and suitable for occupancy:

    - Builder has completed all major interior construction work.2
    - Builder has completed all major finishing work within the building.3
    - Interior electrical and plumbing work has been completed.
    - The interior is cleaned of all construction and/or finishing materials (i.e. floor, walls, counters, appliance(s), duct work, etc.). 

Rough-in work, which is work the occupant completes after moving in, is not considered part of ongoing construction or finishing stages during initial installation inspections.


Inventory Homes:
 

Sometimes builders may develop inventory homes, which will be sold at a later date and will not have all interior finishing completed. In these situations, gas will be activated in accordance with temporary heat guidelines. Initial installation inspections should only be requested after all major interior finishing work is completed. Temporary heat (construction and finishing) guidelines can be found on our website at www.buildwithgas.com.


Initial Installation Checklist: 

  • All major construction and finishing work has been completed.
  • The home has been cleaned of all construction and finishing materials.
  • All gas equipment is  fully installed as per local code and ready to be activated.
  • Furnace and ductwork are cleaned and new filters installed to ensure there is no residual drywall and/or construction debris.
  • Manufacturers’ installation and operation instructions are present.
  • All interior/exterior gas piping is installed in accordance with all local code.
  • Pressure test tag(s) are complete and present.
  • All appliance vents (combustion and air intake) are installed in accordance with all local codes.
  • All gas pipe and appliance vents are sealed at entrance points.
  • All clearances to the natural  gas meter and regulator(s) are met.


Important:

  • Initial installation inspections are a regulatory requirement by the distributor to ensure the safe delivery of natural gas to its customers, and that an appliance will only be operated within environments in which it was intended.
  • Initial installation inspections are distributors inspections. They are not meant to be inspections for commissioning. Appliance and/or equipment commissioning is the sole responsibility of the HVAC contractor. Enbridge is not responsible for final setup/commissioning of appliances under any circumstances.
  • If the furnace was activated for finishing heat, the finishing heat activation form must be completed and present at time of initial installation inspections.
  • The builder must make arrangements with the heating contractor for final verification of set up and proper operation of the natural gas equipment.

Click the Inspection Prior to Homeowner Occupancy request form to fill out the addresses, list all appliances to be inspected, and request a day for an inspector to attend. You will receive a confirmation email for your records. 

** It is the responsibility of the builder to contact Enbridge Gas Distribution for inspection before the appliances are turned on. We require a minimum of 48 hours’ notice. Before contacting Enbridge Gas Distribution to schedule the initial installation inspection, the site must be fully accessible to the inspector.


  • 1 Homes where the furnace was previously activated for residential finishing heat must have the Finishing Heat Activation Form on site for verification at time of initial installation  inspections.  

  • 2 Homes that still have exterior finishing work to be completed can request initial installation inspections provided all interior requirements are met.  

  • 3 Occasionally items such as carpet installation, change orders, minor trim work, minor floor or tiling work may not be fully completed at the time of initial installation inspection requests. Depending on the adverse effect this work may have on the operation or installation of the natural gas equipment, the inspector will choose to accept or reject the installation.
