What if a Vancouver survey pin cannot be found?

If you can't find your survey pins in Vancouver, do not guess at the property line and do not start digging post holes. Missing or buried survey pins are a common problem in Metro Vancouver's older neighbourhoods, and proceeding without confirmed boundaries is one of the most expensive mistakes a homeowner can make.

Why Pins Go Missing

Survey pins (also called iron bars or survey monuments) are small metal stakes driven into the ground at property corners by a BC Land Surveyor. In established Vancouver neighbourhoods like Kitsilano, East Van, or Strathcona, pins can be 40-80 years old. They get buried under decades of soil and mulch accumulation, paved over during driveway or sidewalk work, disturbed during utility installations, or simply corroded and difficult to detect. In newer subdivisions in Surrey, Langley, or Maple Ridge, pins are more likely to be intact — but even recent pins can be disturbed by landscaping or grading work.

What To Do When Pins Are Missing

Your first step is to check the BC Land Title Office records. Your property's legal survey plan is registered there and shows the dimensions and bearings of your lot. You can access survey plans through the BC Land Title and Survey Authority (LTSA) at ltsa.ca — a copy of your survey plan costs a small fee and gives you the legal dimensions to work from. However, interpreting a survey plan and translating it to physical ground locations requires expertise.

If the plan doesn't get you to a confident answer, hire a BC Land Surveyor to locate or re-establish your pins. This is the only legally reliable way to confirm your property boundaries. A surveyor will use the registered plan, GPS equipment, and measurements from known reference points to locate existing pins or set new ones. Expect to pay $1,500–$3,500 for a residential boundary survey in Metro Vancouver, depending on lot complexity, how much archival research is required, and whether new pins need to be set. That cost is significant, but it is far less than the legal and financial consequences of building a fence on your neighbour's property — which can require removal at your full expense plus potential liability for damages.

The Risk of Guessing

In Metro Vancouver's urban neighbourhoods where lots are often only 33 feet wide, being off by even 6 inches on a property line is a meaningful encroachment. A fence built even slightly over the line onto a neighbour's property can trigger a dispute under the BC Property Law Act, require a formal survey to resolve, and potentially require you to tear out and rebuild the fence entirely. The cost of a survey before construction is almost always less than the cost of a dispute after.

Practical Steps Before Your Fence Project

Before any fence installation near a property boundary, call BC One Call at 1-800-474-6886 to get a free utility locate — this is legally required before digging in BC. Then pull your property's survey plan from the LTSA. If you can locate your pins using the plan dimensions and a measuring tape, mark them clearly. If you cannot confidently locate all four corners, bring in a BC Land Surveyor before you proceed.

A good fence contractor will ask about your property boundaries before starting work. If a contractor is willing to install a fence without any discussion of where the property line actually is, that's a red flag worth taking seriously.
