Building code and bylaw information

Note: It is the responsibility of the applicant to ensure that the work being carried out conforms to any restrictive covenants, caveats or other restrictions that are registered on the land title.

Where to install an air conditioning unit

You can install an air conditioning unit in a front, rear and side setback with the following conditions:

  • Air conditioning units can only project 1.0 m into any side setback area.
  • Air conditioning units cannot be located in a side setback area that is required to be clear of projections. These projections include: air conditioning equipment, window wells, cantilevers and other portions of the building.
  • One side setback is required to be free and clear of projections.

Note: This does not include cantilevers and portions of the building higher than 2.4 m above grade. i.e; an upper floor cantilever.

Air conditioning in side yard

When air conditioning units are proposed on the same lot as a semi-detached dwelling:

  • Equipment is only permitted when one side setback area is on the street side of a corner parcel.

Previously installed air conditioning units

If you have a previously installed air conditioning unit that does not meet the Land Use Bylaw rules, a development permit for relaxation is required.

If the air conditioning unit was installed prior to June 1, 2008, there were no bylaw rules for air conditioning equipment and proof of installation is required to confirm the installation date.

Acceptable forms of proof are:

  • An official receipt or invoice showing the installation date (not the purchase date) of the equipment.
  • The builder’s purchase agreement showing record of air conditioning installation.

Inspection information

All residential construction and electrical permits can be booked at 311 online services Inspection - Residential Improvement Project/Electric. Plumbing and gas permits can be booked by contacting 311 and providing them with your permit number.

Generally, your project will require a rough-in and a final inspection for each building and trade permit pulled, though additional inspections may be required. You can contact 311 on the morning of your inspection to find out if it will be in the morning or afternoon.

A development completion permit inspection may be required if a development permit is involved in your project. Call our Planning Services Centre at 403-268-5311 to determine if a development completion permit is required.

The inspection process is dynamic and an inspection outcome depends on the construction method and site conditions at time of inspection. The information provided is not intended as an exhaustive list, but a generalized outline of the inspection process.
