<\/p>\n
Front Lot Line<\/h3>\n
The front lot line is the boundary that touches the street.
\n\u2022 Determines where your front yard setback is measured from.
\n\u2022 Establishes the \u201cfront\u201d orientation of your lot for all other zoning calculations.
\nExample<\/strong>: On a standard residential lot, the line along the sidewalk or street curb is your front lot line.<\/p>\nRear Lot Line<\/h3>\n
The rear lot line depends on the shape of your lot:
\n\u2022 Rectangular or square lots<\/strong> \u2192 The line directly opposite the front lot line.
\n\u2022 Three-sided lots<\/strong> \u2192 The point where the other two boundaries meet, farthest from the front lot line.
\n\u2022 Irregular lots<\/strong> \u2192 The boundary farthest from the front lot line, including angled connections under 45 degrees.
\nExample:<\/strong> On an L-shaped lot, the \u201crear\u201d may not be obvious zoning rules apply the 45-degree rule to determine it.<\/p>\nSide Lot Lines<\/h3>\n
Side lot lines are all property boundaries that aren’t front or rear lot lines. They run between the front and rear boundaries along the sides of your property.<\/p>\n
Why Lot Lines Matter in Toronto Zoning<\/h2>\n
Every setback rule ,front yard, rear yard, and side yard; is measured from these lot lines. If you misidentify them, you risk:
\n\u2022 Incorrect setback calculations
\n\u2022 Permit application delays
\n\u2022 Costly redesigns of your project
\nThis is especially important for irregularly shaped lots, where the rear and side lines may not be obvious.<\/p>\n
Irregular Lots Need Extra Attention<\/h3>\n
Properties with unusual shapes require careful analysis to determine which boundaries count as rear versus side lot lines. The 45-degree angle rule for rear lot lines can affect setback calculations significantly.<\/p>\n![\"Side](\"https:\/\/landsignal.ai\/blog\/wp-content\/uploads\/2025\/09\/1-2.png\")
