How do I find the property pins before installing a fence in my Coquitlam yard?

Finding your property pins before fence installation is absolutely critical in Coquitlam — building even a few inches onto your neighbour's property creates legal liability and may require expensive fence removal. Property pins (also called survey monuments) are small metal or concrete markers placed by licensed BC Land Surveyors to mark the exact corners and boundaries of your lot.

Start by checking your property documents for an existing survey plan. When you purchased your home, you should have received a copy of the legal survey or a "Form A" from the BC Land Title Office that shows your property boundaries and dimensions. This survey plan will indicate where property pins should be located, typically at lot corners and sometimes at intermediate points along long boundaries. The survey shows distances between pins and their relationship to permanent features like your house, driveway, or large trees.

Physically locating the pins requires some detective work. Property pins in Coquitlam are usually small iron bars (about 1/2 inch diameter) driven flush with the ground, sometimes with a plastic or metal cap marked with the surveyor's information. They may be buried under several inches of soil, grass, or landscaping that has accumulated over the years. Use a metal detector to scan the areas where your survey plan indicates pins should be located — you can rent one from tool rental shops for about $30-50 per day. Start your search at lot corners, measuring from your house or other known reference points shown on the survey.

If you cannot locate the pins yourself, hire a BC Land Surveyor to re-establish your boundaries. This is the most reliable approach and costs $1,000-$3,000 depending on lot size and complexity. The surveyor will use professional equipment to locate existing pins or set new ones if the originals are missing or damaged. They'll provide you with a current survey plan showing exact measurements and pin locations. Many Coquitlam properties, especially older subdivisions, have pins that were damaged during landscaping or construction over the decades.

Coquitlam-specific considerations include the city's varied terrain and development patterns. Properties on slopes, near ravines, or in areas with significant tree cover may have pins that are harder to locate. Some older Coquitlam subdivisions have property lines that don't run perfectly parallel to streets or houses, making visual estimation unreliable. The City of Coquitlam building department can provide information about your specific lot's survey history, though they cannot locate pins for you.

Never assume your existing fence marks the property line. Many fences in Coquitlam were built without proper surveys and may be several feet inside or outside the actual boundary. Neighbours sometimes agree to fence placement that doesn't follow the legal property line, but these informal arrangements don't change the legal boundaries and can create problems when properties are sold.

Before any fence installation, also call BC One Call (1-800-474-6886) for a free utility locate service. This marks underground gas lines, electrical cables, water mains, and telecommunications that could be damaged during post hole digging. This service is free and legally required in BC before any excavation.

Consider the investment perspective — spending $1,500-$2,500 on a professional boundary survey before installing a $5,000-$10,000 fence protects you from potentially having to remove and rebuild sections that encroach on neighbouring property. Boundary disputes between neighbours can cost tens of thousands in legal fees and create lasting animosity.

Once you've confirmed your property boundaries, you can confidently plan your fence placement, typically setting it 2-6 inches inside your property line to avoid any accidental encroachment and allow for maintenance access.
