Section 5 of the by-law sets the residential maximums; Section 6 sets the exceptions.
How high can a fence be in Oakville?
In a residential zone, 2 metres (6 feet 6 inches) in any yard other than a front yard, and 1.5 metres (5 feet) in a front yard. Any part of a front-yard fence above 1 metre (3 feet 3 inches) must be commercially available open lattice.
Height is measured from the grade at the base of the fence, and where the fence steps, it is taken as the average height over any 2.44 metre (8 foot) portion.

Can a fence on the property line be higher than 2 metres?
Yes. A boundary fence in a side yard, rear yard or flankage may reach 2.2 metres (7 feet 4 inches), provided any portion above 1.9 metres (6 feet 2 inches) is commercially available open lattice.
A boundary fence is one located wholly or partly within 0.91 metres (3 feet) of a property line. Where neighbouring lots sit at different grades, its height is measured from the mean grade between the two lots.

They are allowed to exceed it. Gates may be up to 30 centimetres (1 foot) above the limit, an archway forming part of an entrance may reach 2.3 metres (7 feet 6 inches), and decorative caps on structural posts may add up to 15 centimetres (6 inches).

Can I fence a tennis court higher?
Yes. A fence enclosing a tennis court or similar private sports facility in a rear or side yard may be up to 3.7 metres (12 feet), must be chain link with corrosion-resistant or treated posts and bracing, and must sit at least 0.6 metres (2 feet) from any property line.
This provision explicitly does not cover pools. A pool enclosure is governed by the separate Pool Enclosure By-law and needs its own permit.
