In the Residential Zone category, if a lot is located:

Beside one lot in the Residential Zone category, and that abutting lot has an existing principal buildingfronting on the same street and located, in whole or in part, 15.0 metres or less from the subject lot, theminimum required front yard setback is the existing front yard setback of that principal building on theabutting lot; or

Between two abutting lots in the Residential Zone category, each with an existing principal buildingfronting on the same street and located, in whole or in part, 15.0 metres or less from the subject lot, theminimum required front yard setback is the average of the existing front yard setbacks of those principal buildings on the abutting lots.

Lot Coverage means the portion of the lot that is covered by any part of any building or structure on or above the surface of the lot. 800.50 Defined Terms (415)

Building Depth means the horizontal distance between the front yard setback required on a lot and the portion of the principal building's rear main wall furthest from the required front yard setback, measured along a line that is perpendicular to the front yard setback line. 800.50 Defined Terms (100)

Building Length means the horizontal distance between the portion of the front wall of a principal building on a lot closest to the front lot line, and the portion of the rear main wall of the building closest to the rear lot line, measured along the lot centreline. If the relevant parts of these walls are not intersected by the lot centreline, the measurement is from the point on the lot centreline where a line drawn perpendicular to the lot centreline connects with the relevant part of the wall. 800.50 Defined Terms (105)

What is Floor Space Index (FSI)?


LA Lot Area

A FSI = 1.0Covering = 100% of lot on 1 floor

B FSI = 1.0Covering = 50% of lot on 2 floors

C FSI = 1.0Covering = 25% of lot on 4 floors

Floor Space Index (FSI) means the gross floor area of all buildings on a lot divided by the lot area. 800.50 Defined Terms (255)

FSI


How is Gross Floor Area (GFA) Calculated?


1 First Floor G Garage *(NOT INCLUDED IN GFA)

B Basement *(NOT INCLUDED IN GFA)

2 Second Floor

Gross Floor Area (GFA) means the total area of each floor level of a building, above and below grade, measured from the exterior of the main wall of each floor level, including voids at the level of each floor, such as an atrium, mezzanine, stairwell, escalator, elevator, ventilation duct or utility shaft, but excluding areas used for the purpose of parking or loading. 800.50 Defined Terms (310)

Exclusion of Basement from Gross Floor Area in a Residential Building Despite the definition of gross floor area in this By-law, for a lot in a Residential Zone category, the gross floor area of a residential building does not include the basement, unless the elevation of the established grade is higher than the average elevation of grade along the rear main wall of the residential building by 2.5 metres or more, in which case 50% of the gross floor area of the basement is included.

Established Grade means the average elevation of the ground measured at the two points where the projection of the required minimum front yard setback line is 0.01 metres past each side lot line.By-law Section 800.50-240 Defined Terms.

Determining the Height of a Principal 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.

A detached house in an RD zone that has a roof with a slope greater than 1.0 vertical units for every 4.0 horizontal units, for more than 50% of the total horizontal roof area; the maximum height for a principal building or structure on a lot is the numerical value shown in metres on the Height Overlay Map.
