Fence Installation Cost in London (2026)

Generally, no. In London, residential fences do not require a permit unless they are for a swimming pool enclosure or exceed 2 metres (6.5 feet) in height. However, you must still comply with the City of London Fence By-law regarding height and location.

Contractors in London recommend a minimum depth of 48 inches (4 feet) for fence posts. This ensures the footings are below the local frost line, preventing the fence from leaning or shifting during Ontario's freeze-thaw cycles.

The standard maximum height for a fence in a rear or side yard is 2 metres (approximately 6.5 feet). Front yard fences are more restricted, typically limited to 1 metre (3.3 feet) to maintain visibility and neighborhood aesthetics.

Under the Ontario Line Fences Act, neighbors can be required to share the cost of a basic 'fence of reasonable quality.' Typically, this results in a 50/50 split of the cost for a standard pressure-treated wood fence, though agreements should be made in writing before construction starts.
