Mississauga’s fence guidance distinguishes a closed panel from an open one. A front-yard fence of closed construction is limited to 1 m, while an open design can reach 1.5 m; “open” means at least one-third of the fence is see-through. A typical rear or side fence may reach 2 m, but the location beside a neighbour’s front-yard driveway adds another test: a rear-yard fence within 4.5 m of that driveway must be open construction. A solid six-foot privacy run turning a corner toward a neighbour’s driveway may fail even though its height never exceeds 2 m.
The City says a permit may not be needed for most fences, but that does not authorize use of its road allowance. The Fence By-law covers hedges, shrubs and trees acting as fences as well as constructed barriers. Mark the survey boundary, adjacent driveway and corner sight triangle before ordering solid panels. Mississauga also prohibits hazardous material such as barbed wire on residential fences. If the neighbour shares the line, its division-fence procedure and notices address cost disputes separately from height compliance; the City says it does not decide the location or price disagreement between owners.
There is a formal fence-exemption route for noncomplying proposals. The City asks for a survey, site plan, fence specifications, photographs and the particular bylaw section from which an exemption is sought; it notifies common-boundary neighbours and can consider their feedback. Its listed sections include the 2 m overall limit, the two front-yard construction thresholds and the adjoining-driveway openness rule. An exemption application is a request for a decision, not permission to install now. For example, an owner seeking a 1.8 m solid front screen should identify the closed-construction front-yard restriction, show why the street-facing view remains safe, and wait for the City’s decision. A pool enclosure or a privacy screen may invoke its own provisions, so describe the function rather than calling every barrier an ordinary fence.
