Whether you're planning to build a fence, construct a new home, develop a property or resolve uncertainty about your property lines, understanding the legal boundaries of your land is essential.
Property boundaries are established through legal survey records and evidence, not simply by the location of an existing fence, hedge or driveway.
At Spatial Surveys Land Surveying Inc., we provide professional legal and boundary surveying services throughout Surrey, Vancouver, Langley, White Rock, Delta and the surrounding Lower Mainland.
What Is a Legal Land Survey?
A legal land survey establishes or documents property boundaries and other legal interests in land using registered survey records, physical survey evidence and applicable surveying standards.
In British Columbia, legal cadastral surveying is performed under the professional authority of a British Columbia Land Surveyor (BCLS).
Depending on the purpose, a legal survey may involve locating existing survey monuments, determining property corners, restoring missing monuments or preparing a legal survey plan for registration.
Legal surveying forms an important foundation for property ownership, land development and construction.
What Is a Boundary Survey?
A boundary survey determines the legal position of a property's boundaries using available survey evidence and registered records.
A professional boundary survey may involve:
Reviewing registered subdivision and reference plans.
Examining relevant Land Title and Survey Authority of British Columbia (LTSA) records.
Searching for existing legal survey monuments.
Measuring and verifying boundary evidence.
Determining property corner positions.
Marking confirmed boundary positions as appropriate.
Preparing survey documentation where required.
An important distinction is that a boundary survey does not always require a new legal plan to be registered. The appropriate deliverable depends on why the survey is being undertaken.
When Do You Need a Boundary Survey?
1. Installing a Fence or Retaining Wall
An existing fence does not necessarily represent the true legal property boundary.
Before installing a new fence or retaining wall, determining the boundary position can help prevent encroachments onto neighbouring land.
A boundary survey provides reliable information for planning improvements close to your property line.
2. Building a New Home or Addition
Accurate boundary information is essential when positioning new buildings and evaluating required setbacks.
Architects, designers and builders rely on dependable property information to develop suitable plans and avoid preventable construction conflicts.
3. Locating Missing Property Corners
Over time, property monuments may become buried, disturbed or removed during construction and landscaping.
A BC Land Surveyor can investigate the available evidence and determine the appropriate procedure for identifying or restoring property corner positions.
4. Resolving Boundary Uncertainty
Disagreements concerning fences, retaining walls, landscaping and other improvements can arise when neighbouring property owners have different understandings of their shared boundary.
A professional boundary survey provides an evidence-based determination of the boundary position and can help inform discussions between property owners.
Surveyors establish boundary evidence; they do not independently resolve every legal dispute concerning ownership or property rights.
5. Property Development and Subdivision
Legal surveys also play an important role in subdivisions, strata developments, road dedications and easements.
These projects may require registered survey plans prepared under the authority of a British Columbia Land Surveyor.
What Is a Section 68 Posting Plan?
In British Columbia, a posting plan under Section 68 of the Land Title Act is a particular type of legal survey plan used in appropriate circumstances to document the placement or restoration of survey monuments.
A posting plan may be necessary when the required boundary monumentation cannot be adequately documented through an existing registered survey plan.
The need for a posting plan depends on the property's legal survey history, available evidence and the circumstances of the work.
At Spatial Surveys, we assess the available records and surveying requirements before advising which service is appropriate.
Can I Locate My Property Line Using GPS or an Online Map?
Online property maps, municipal GIS viewers and smartphone GPS applications can be useful for general property research.
However, they should not be relied upon to establish exact legal boundary positions.
Digital parcel boundaries may be based on mapping information that does not reproduce the precise position established by legal survey evidence.
When accuracy matters for fences, structures, setbacks or potential encroachments, a professional boundary determination is the appropriate approach.
How Much Does a Legal Boundary Survey Cost in BC?
The cost of a legal survey depends on the type of work required and the condition of the existing survey evidence.
Factors influencing the cost include:
Property size and configuration.
Availability of reliable existing survey monuments.
Age and complexity of registered survey records.
Terrain, vegetation and accessibility.
Whether survey monuments need to be restored.
Whether a new legal survey plan must be prepared and registered.
A straightforward boundary investigation can differ significantly in scope and cost from a registered posting plan or subdivision survey.
At Spatial Surveys, we review the requirements and provide a clear quotation based on the work necessary for your property.
What's the Difference Between a Boundary Survey and a Topographic Survey?
Although both services involve precise field measurements, they serve different purposes.
Boundary Survey: Focuses on determining the legal property boundaries using survey evidence, records and applicable professional standards.
Topographic Survey: Documents the existing physical features and elevations of a site for architectural design, engineering and development planning.
Some projects require both services, particularly when legal boundaries and detailed site conditions are needed for design or construction.
