A permit is required to install, alter or add to a gas system. A gas permit is required to ensure that all gas piping systems comply with the Natural Gas and Propane Installation Code (B149.1-10). A qualified gasfitter, licensed by the City of Medicine Hat must submit the gas permit application, unless the work is done under a Homeowner's Permit.


A Gas permit is not required for the replacement of a dryer, range, water heater or gas furnace if:

  1. it is located in a Single Family Dwelling, and
  2. there is no design change in any gas piping or venting system.

Licensed Contractors:

  • A permit to carry out gasfitting work may be issued to the to the following person:
    • a trained gasfitter;
    • the owner of a business employing a trained gasfitter;
    • a plant gasfitter for gasfitting work to be carrier out exclusively on the premises of his employer.
  • A Licensed Contractor can submit a Gas Permit Application by fax to 403.502.8036.
Homeowner's Permit:
  • As a homeowner, you may apply for a Homeowner's Permit if:
    • You own and reside in the premise where the work is to be carried out, and
    • The work is to be completed for a Single Family Dwelling, and
    • You are properly trained in the installation, operation and maintenance of a gas service to ensure the work will be done in accordance to CSA B149.1-10 and the Safety Codes Act.
  • You may not apply for a Homeowner's Permit if:
    • You will not personally be completing the work or
    • You are not a trained gasfitter, or
    • If the work involves a Secondary Suite or Rental Property.
  • Complete the Gas Permit Application and Homeowner's Acceptance Form and submit in person at the Planning, Building and Development Services department on the 2nd floor of City Hall.

Note: If you have no previous knowledge or experience with gasfitting, it would be in your best interest to hire an licensed gasfitter  who is eligible to receive permits. Work completed by inexperienced individuals often requires extensive corrections to bring the installation up to code, and may create a serious hazard.

Permit Cancellation:

A Safety Codes Officer may, by written notice sent or delivered to the applicant at the address or telefax number on the application, cancel or suspend a permit if he is aware that:
  1. in the case of an addition or alteration, the existing gas system in or on the building or premises does not comply with the Safety Codes Act;
  2. incorrect information was submitted in or with the application for the permit;
  3. information submitted with the application is inadequate to determine whether the gasfitting work complies or will comply with the Safety Codes Act;
  4. the gasfitting work for which the permit was issued does not or will not comply with the Safety Codes Act or the permit or any condition thereof; or
  5. the permit was issued in error.
 Expiration of Permit:
A gas permit expires if the work is not commenced within 180 days of the issuance of the permit or if no work is carried out under the permit for a period of 180 consecutive days. Upon written application made prior to the expiry of the permit, the Safety Codes Manager may extend the time period for a permit by an additional 180 days.
