Fence rules in Oak Bay

How tall a fence may be in Oak Bay

In the street-facing part of a lot a fence may not exceed 1.38 m (4.5 ft). Oak Bay measures that zone within 7.62 m (25 ft) of any property line abutting a street. Elsewhere on the lot the maximum is 2 m (6.6 ft).

The rules live in a standalone Screens and Fences Bylaw, not the zoning bylaw. The governing document is the Screens and Fences Bylaw No. 3536, 1986 (amended by 3546, 3602 and 4282).

How the height is measured — and why that matters more than the number

Oak Bay measures from the top of the fence down to the HIGHEST natural ground within 1 m in any direction — the most builder-friendly rule in the region.

Four municipalities in this region measure the same fence four different ways. A fence built to the limit under one method can be over the limit under another, which is why a contractor who works across Greater Victoria cannot carry one number in their head.

If the fence sits on a retaining wall

In Oak Bay: the bylaw caps a wall's exposed face at 1.2 m but states no combined wall-plus-fence rule; its fence definition includes "a wall", which is unresolved.

This is the single clause that most often decides a terraced lot, and the region splits on it. The City of Victoria measures from the high side of the wall, so the wall costs the owner nothing. Sidney, Saanich, Central Saanich and View Royal count the wall against the fence. Same drawing, opposite answers.

Corner lots and sight lines

On a corner lot: 1 m (3.3 ft) inside the triangle. The triangle is measured a 25 ft square whose corner sits at the intersection of the PAVED ROADS, with one side along the road edge. Measured off the asphalt, not the lot line — on a wide boulevard that is a real difference.

Do you need a permit?

None. The building bylaw excludes fences from "structure", though a retaining wall of 1.2 m or more does need one.

In ten of the thirteen Greater Victoria municipalities an ordinary residential fence needs nothing at all. The exceptions are Langford, where a fence inside a wildfire-interface or riparian development permit area needs a Development Permit; North Saanich, where a fence of 2 m or more is a "structure"; and Colwood, where a pool fence needs a building permit.

If your lot touches water

No fence within 7.62 m of a stream's high water mark or the top of a ravine bank; between 7.62 m and 10 m the Riparian Areas Regulation assessment process applies.

This is where the thirteen disagree most sharply. Highlands and View Royal prohibit a fence outright within 30 m of fresh water; Central Saanich expressly exempts fences from its marine setback. Knowing which side of a municipal boundary you are on changes the answer completely.

How do you know whether you are inside it? The distance is measured from the natural boundary, and that is not the edge of the water on the day you look — it is the line the water has marked on the ground over time, and on a creek it can sit well back from today's flow. You cannot pace it out and be safe. The people who establish it are a BC land surveyor, or a Qualified Environmental Professional where the Riparian Areas Regulation applies, and several of these bylaws name a QEP themselves. If your lot touches a creek, a ditch that runs most of the year, a pond or the sea, get that line located before you price a fence — it is cheaper than moving one, and in Oak Bay it may decide whether there is a fence at all.

Pool enclosures

Not less than 1.2 m; no opening that passes a 100 mm sphere; nothing between 100 mm and 1 m above the ground that would help a child climb; self-closing self-locking gates kept locked when not in use.

A pool enclosure is the one fence rule that is a minimum rather than a maximum: no enclosure, no water.

What beats these figures in Oak Bay

Everything above is the general case for an ordinary lot. Each layer below can override it, and for a large minority of properties at least one does. They are not exotic — a creek or the shoreline, a strata bylaw, an easement and a heritage designation.

Any part of the lot near the sea, a lake, a pond, a wetland or a watercourse: Oak Bay does not permit a fence there at all. A ditch that runs most of the year can be a watercourse, and the distance is measured from the natural boundary, which is not the edge of the water today.

A strata bylaw, or a restrictive covenant on your title: Either can forbid a fence Oak Bay would allow, dictate its style, height and colour, or require written approval first. Where the ground is common or limited common property you do not control it alone. If you rent, you cannot authorise a fence at all — the owner has to ask.

An easement or right of way crossing your land: A fence is generally not permitted across an easement unless that easement allows it, and it is on your title rather than in any bylaw. Search the title before you set the line.

The Uplands design guidelines, which do not reach a fence: Oak Bay has no heritage conservation area. In the Uplands, design guidelines sit on top of the fence bylaw, and this layer is here mostly to say they stop short of one. The Uplands Design Guidelines do speak to fences: “Fencing and walls should be used in a manner that promotes the open park-like concept of the Uplands. Enclose outdoor spaces with plants, screening, and layering of plants and features.” But the Uplands Design Guidelines Review Form is required of “anyone proposing a new building or an addition or alteration to an existing building in the Uplands”, and a fence on its own is not on that list. So the guideline is the District’s stated expectation, not an approval you have to win first. What can actually stop an Uplands fence is the building scheme registered against the title, which is a title search rather than a bylaw.

Your zone is named on your property tax notice. Easements and covenants are on your title. The municipality will confirm both.

The trees on your fence line

Almost every fence line wants a tree or two out of the way, and in twelve of the thirteen Greater Victoria municipalities that is regulated — often more tightly than the fence itself. Oak Bay: Tree Protection Bylaw No. 4742, 2020 (consolidated 10 March 2025).

The smallest tree that is protected here: A Garry oak, Arbutus, Pacific Yew, Black Hawthorn, Shore Pine or Pacific Dogwood with a basal diameter over 4 cm or a height over 1 m. Any other tree at a DBH over 30 cm.

Topping, pruning, bark removal and cutting roots inside the drip line are all prohibited without a permit.

Oak Bay defines a boundary tree — one whose trunk or visible root flare crosses the property line — and to remove one you must supply a letter from the adjacent owner agreeing to it. It is the same consent rule the fence itself follows when it sits on the line.

Across the region the smallest protected tree ranges from three centimetres thick in Sidney to eighty in Highlands, and Sooke is the only one of the thirteen with no tree bylaw on private property at all. Walk the line and identify what is in the way before you accept a quote, not after the posts are ordered.

The same fence, across a municipal boundary

Greater Victoria is thirteen separate local governments and the boundary between two of them often runs down the middle of an ordinary residential street. Here is what the same fence runs into a short distance from Oak Bay.

On a retaining wall Victoria measures from the high side, so the wall costs nothing there — in Oak Bay it comes straight off your fence height.

Near water the two are opposites: Oak Bay prohibits a fence outright, Central Saanich expressly exempts fences from its marine setback.

Colwood sets no fence height limit at all, where Oak Bay holds you to 2 m (6.6 ft).

On a corner lot Oak Bay caps it at 1 m inside the triangle; Esquimalt has no corner rule for fences at all.

None of this is a claim about which municipality borders Oak Bay — that is a geographic question we have not verified. It is a claim about how far apart the rules are inside one region.

Is a fence a "structure" in Oak Bay?

A fence IS a structure in the zoning bylaw (which is why the riparian rule reaches it) but is NOT a structure in the building bylaw (which is why no permit is needed).

It sounds like a technicality and it is not. A rule written for "structures" — a water setback, a permit trigger, a setback from a lot line — reaches a fence only where that municipality counts a fence as one. The region is split roughly down the middle.

What we could not settle

The Screens and Fences Bylaw defines "fence" to include a wall, while the zoning bylaw regulates retaining walls separately at 1.2 m. Whether wall and fence are read together, as Sidney reads them, is not resolved on the face of either document.

We publish open questions rather than smoothing them over. If a figure here matters to a job you are about to commit money to, confirm it with the municipality for your exact address.
