Who is responsible for a fence on the property line in British Columbia?

In British Columbia, when a fence sits directly on the property line between two properties, both property owners share responsibility for its maintenance and repair under Part 5 of the BC Property Law Act. This shared responsibility applies regardless of who originally built the fence, though the specifics of cost-sharing and decision-making can be more nuanced than many homeowners realize.

Part 5 of the BC Property Law Act (Boundaries) establishes the legal framework for shared boundary fences. The legislation provides that both owners benefit from a boundary fence and therefore both share the obligation to maintain it in reasonable repair. This means if the shared fence is falling down, rotting, or leaning, neither owner can simply ignore it and claim it's the other person's problem. Both parties are expected to contribute to keeping the fence in functional condition. The Act also provides a process for resolving disputes when neighbours cannot agree on fence matters.

However, "shared responsibility" does not automatically mean a 50/50 cost split on every fence project. If one owner wants to replace a functional fence with something more expensive — upgrading from a basic pressure-treated fence to a premium cedar board-on-board design, for example — the other owner is not obligated to pay half the upgrade cost. The shared obligation covers maintaining a reasonable fence in reasonable repair. If one owner wants something beyond what's reasonable, they typically bear the additional cost themselves. What constitutes "reasonable" depends on the neighbourhood standard, the condition of the existing fence, and local property values.

If you want to build a new boundary fence or replace an existing one, communicate with your neighbour first. The best approach is to discuss the project before getting quotes, agree on the fence style and materials, get two or three quotes together, and agree on the cost split in writing. A simple written agreement — even a signed email exchange — outlining what fence will be built, the total cost, each party's share, and the timeline prevents misunderstandings and provides a record if disputes arise later.

What if your neighbour refuses to contribute? If your neighbour will not share costs for a boundary fence that is in disrepair or does not exist, the BC Property Law Act provides a mechanism for resolution. You can apply to the BC Supreme Court for an order requiring your neighbour to contribute to the cost of erecting or repairing a boundary fence. However, court proceedings are expensive — legal fees alone can easily exceed the cost of just building the fence yourself. In practice, most homeowners who face an uncooperative neighbour either build the fence at their own expense (setting it 2-4 inches inside their own property line to avoid any boundary issues) or use mediation services to reach an agreement.

The BC Civil Resolution Tribunal (CRT) handles some property disputes and may be a more affordable alternative to Supreme Court for fence disagreements involving smaller amounts. The CRT process is largely online, fees are modest, and decisions are legally binding. Check the CRT website to confirm whether your specific fence dispute falls within their jurisdiction.

Practical considerations for shared boundary fences in Metro Vancouver. In Vancouver's older neighbourhoods — Kitsilano, Dunbar, Kerrisdale, East Vancouver — many boundary fences are 50-80 years old and have been replaced multiple times without formal agreements. When it's time for a new fence, start the conversation early. Most neighbours in Metro Vancouver are reasonable and willing to split costs for a shared fence, especially when presented with fair quotes and a good-neighbour approach. A typical 6-foot cedar privacy fence costs $40-$80 per linear foot installed, so a 100-foot shared boundary fence at $5,000-$8,000 total becomes $2,500-$4,000 each — a manageable investment that benefits both properties.

Good neighbour fence design matters on shared boundaries. A board-on-board (shadowbox) fence looks identical from both sides, which eliminates the awkward conversation about who gets the "good side" versus the post-and-rail side. Shadowbox fences cost 10-15% more than flat-board designs but are well worth it for shared fences — they also handle Metro Vancouver's wind conditions better by allowing air to pass through the gaps.
