General addressing guidelines

Standard address format

A City of Calgary (or Civic) standard address consists of the following components:

Suite number (where applicable) – spaces in multiple tenancy buildings are often given a number or letter to supplement the basic address. These identifiers may be alphabetical, numeric or a combination of both. Suite numbers are shown at the start of the address. (For example - #101 2012 29 ST SW).

  • A suite number may designate a sub-unit located within a building or may indicate direct access to the building’s exterior.
  • In a suite number, generally, the graduating numbers are the last two digits and the leading number(s) indicates the floor.
  • Leading numbers indicate the suite’s placement within the building and sometimes the building number.

For example - #1101 2404 1 ST SW (1101 indicates the suite is on the 11th floor).

House and building numbers - All properties along a roadway are assigned consecutive numbers, usually starting at one end and finishing at the opposite end. This numbering system represents an incremental distance along the road.

  • The address must appear on the outside of a building to indicate the building's location in relation to the buildings on the block.
  • A house number must be visible from the road and lane.
  • With a house number on a numbered road, the last two digits are graduating numbers which increase as a person travels up the road. The leading numbers, 0-3 digits, represent the hundreds block.
  • A house number on a named road is determined either by the grid system or by a logical starting point on that road.

Street name - Most public roads are either numbered or named. The Calgary Planning Commission and Council approve street names.

Street type - All road descriptions include a street type (sometimes referred to as the street name suffix). The following is a list of street types and abbreviations.

Application form and checklist

Development permit addressing

After review, a development permit can result in addresses being changed or added.

Secondary suite addressing

The City of Calgary requires the assignment of a separate address for secondary suites to supplement the basic address of the main dwelling. The identifier for the secondary suite may be alphabetical or numeric.

A separate secondary suite address serves the following purposes:

  1. Emergency response and wayfinding: If an emergency event occurs in the secondary suite, every second counts and a precise location will assist the emergency responders to locate the suite.

  2. Current and future utility hookups: Utility hookups require the exact suite address where the utilities will be hooked up and for the utility bill to be sent.

  3. Applications for future business licences: A requirement of a business licence is to have the exact suite address to where the business will be operating. Although there might not be a business operating out of the secondary suite at this time, an address will still be created to enable a business to be licenced at the suite when needed.

  4. Applications for future short-term rentals: Although the secondary suite might not be used as a short-term rental at this time, a new address will still be created to enable a suite to be licenced for a short-term rental when needed. The licence requires the exact suite address and not the main dwelling address.

  5. Canada post and other mail delivery services: Although not a City of Calgary requirement, having a separate address for the secondary suite will assist in the delivery of mail to the correct dwelling unit.

The secondary suite address is provided on the Secondary Suite Registry letter and sticker. Once a tenant applies for mail delivery, postal codes are assigned through Canada Post.
