Established Grade

Determining the Height of a Principle Building: Unless otherwise stated in this By-law, in the Residential Zone category the height of a principal building is measured as the distance between the elevation of the established grade and the elevation of the highest point on the building. Established grade means the average elevation of the ground measured at the two points where the projection of the required minimum front yard setback is 0.01 metres past each side lot line.

The Transition Clause allowed for transitioning from old by-laws to the city-wide zoning by-law, and was used for pipeline development applications, recognition of variance and by-law permissions and treatment of existing buildings.

On May 5, 2016 the Ontario Municipal Board heard the City’s motion requesting an amendment to Zoning By-law 569-2013 to extend the Transition Clause Repeal date by 2 years. The Memorandum of Oral Decision and Order issued September 13, 2016 amends the transition clause repeal period in regulation of this zoning by-law from the current 3 year period to 5 years.

The City of Toronto applied the Transition Clause provisions found in Chapter 2 of By-law 569-2013 until May 9, 2018.
