Question 1

Corner fence in Kanata blocked by the triangle rule, options?

Accepted Answer

On a Kanata corner lot, two separate rules limit what you can put near the corner, and understanding both opens up a few practical paths forward. The Fence By-law (No. 2003-462) says no fence over 75 cm within a triangle formed by measuring 3 m along each lot line from the corner. That applies to any fence, solid or open.

Question 2

Where does the 3 m corner triangle start on a Kanata lot?

Accepted Answer

The Fence By-law, as published on ottawa.ca, describes the corner triangle as formed by measuring 3 m along the lot lines from the intersection of the two streets, or of two parts of the same street meeting at an angle of not more than 135 degrees. Inside that triangle, no fence may be higher than 75 cm. There is also a second rule to keep in mind on a corner lot, and it comes from a different source.

Question 3

My Nepean corner fence was built before the rules, now what?

Accepted Answer

Your fence may be allowed to stay as it is, but the answer depends on exactly when it was built and what you do with it next. The City of Ottawa Fence By-law No. 2003-462 came into effect on January 1, 2004. Section 23 says a fence lawfully built under an old municipality's fence by-law before that date may continue in use and be maintained.

Question 4

Corner triangle rules for a fence in Riverside South?

Accepted Answer

Riverside South is fully within the City of Ottawa, so the City of Ottawa Fence By-law No. 2003-462 and Ottawa's zoning by-laws both apply. There are two separate triangle rules that can affect a corner lot here, and they come from different sources with different measurements.
