Regulations and Permit Information

TB198(2)(rev07/14)

ZONING REQUIREMENTSConsult with Planning Information Officer (located in the Planning & Building Division) to determine your property’s zone. The information contained in the table (below) is to be used only as a general guide for a single detached dwelling in a residential zone.

The following zoning requirements refer to the most common minimums for each of the zones listed but may not necessarily apply to all situations. For instance, lots created before 1987 may have dimensions less than those shown but may still be legal.

Where an addition is to be added to a single detached dwelling constructed prior to March 16, 1987, which has less than the required minimum side yards according to the Zoning By-law, the addition shall not be located closer to the side lot lines than the dwelling or 0.6m (23 5/8”) from the side lot line, whichever is greater. You cannot design your project unless you know the limitations set forth in the Zoning By-law.
